Carrolls Woods Master PlanCITY OF ROSEMOUNT EXECUTIVE SUXHARY FOR ACTION CITY COUNCIL MEETING DATE: OCTOBER 1, 1991 AGENDA ITEM: CARROLLS WOODS MASTER PLAN AGENDA SECTION: OLD BUSINESS PREPARED BY: DAVID J. BECHTOL t:- AGENDA E: DIRECTOR OF PARKS & RECREATION 5 A ATTACHMENTS: NONE APPROVED BY: The Carrolls Woods Master Plan Committee has been meeting since early spring. Their goal was to produce a plan that can be used to guide the development of the areas of Carrolls Woods and Schwarz Park in conjunction with a positive relationship with adjoining properties. In'~addition to the many meetings that the Carrolls Woods Committee held to' discuss this project there were also two community input meetings held. At those two meetings citizens were encouraged to voice their concerns and to share thoughts on this project. The copy of the concept plan that you received prior to this',council meeting was developed with the direction of the consulting firm of Brauer & Associates. Jeff Schoenbauer was the principal representing that firm in their consulting role. At the Parks & Recreation Committee meeting of September 16, 1991 this draft of the Carrolls Woods Master Plan was presented to the committee members. Following the presentation by Mr. Schoenbauer the Committee did approve the concept plan and moved to recommend to the City Council that they also approve the plan. RECOMMENDED ACTION: To approve and adopt the Carrolls Master Plan as presented by Brauer & Associates as apart of the planning process of the Rosemount Parks Department.

To accomplish this task, the City. • appointed an ad hoc advisory committee of local citizens to oversee the development of a master plan for the park. • hired the firm of Brauer & Associates, Ltd. to facilitate discussion and develop a park master plan document. The master plan document consists of the following major components: • Development Program: defines the park's general purpose and identifies the major issues affecting its future development. • Alternative Concepts: illustrate a number of schematic designs and physical relationships in response to the development program. • Site Inventory. identifies the site's existing physical characteristics such as soils, slopes, drainage patterns, etc. • Site Analysis: makes judgements about the site and identifies the site's opportunities and constraints for development. • Site Master Plan: is an outgrowth of the accepted concept plan and represents the design solution that best responds to the development program and site inventory/analysis information. • Vegetation Management Program: identifies the key management objectives to assure long term ecological diversity and integrity. • WMdlife Habitat Program: identifies the key management objectives to assure that the needs of wildlife are met. • Cost Estimate and General Phasing Program: projects the anticipated costs to develop the park and establishes a general phasing program. • Education and Interpretive Program: identifies key objectives of education and interpretive programs. • Advisory Committee: defines the critical role the advisory committee will play in overseeing the development of the park. The findings related to each of these components are summarized in the forthcoming text. Development Program The Advisory Committee defined during focus meetings the history and general purpose of the park and identified the major issues affecting its future development. These items make up the development program. The development program is important because it provides the direction and establishes the basis for the entire master planning process. LAWCON Grant Carrolls Woods Park was acquired by the City of Rosemount in 1975 through the State of Minnesota's Outdoor Recreation Grant Program (LAWCON). According to the original grant application, the intent of Carrolls Woods Nature Area 1 City of Rosemount the project was to "protect (from development) a natural, wooded area within a growing part of the metropolitan area" and to "provide some outdoor recreational and outdoor educational opportunities for the citizens of Rosemount." In subsequent years the City applied for a number of revisions and amendments to the original grant. LAWCON, in most cases, granted these requests. Since the original grant was obtained in 1975, the City has created some trails and removed many dead American Elms from the property. There has been no other substantial development. Wayne Sames, Director of the Outdoor Recreation Grant Program (Community Development Division of the Minnesota Department of Trade and Economic Development) represented the State in interpreting the provisions of the various grant application. Under his interpretation, the current level of development was considered to be within the guidelines and general parameters established as part of the original grant application and subsequent amendments. With respect to future development, Mr. Sames indicated that, under the State's interpretation, the park should: a) continue to focus on the preservation of the resource and b) provide passive recreational opportunities, such as nature observation, educational programs, walking trails, benches, etc. for the citizens to enjoy. General Purpose(s) Of The Park Given their understanding of the park's history and what it means to the community, the Advisory Committee was asked to identify what they considered to be the general purpose(s) of the park: Conservation and Preservation: to protect the site and natural environment from encroaching development. Passive Recreation: to provide opportunities for passive recreational activities such as: • walking/hiking (accessible for the handicapped) • nature/wildlife study • family and individual "quiet space" • informal cross-country skiing/snow-shoeing (groomed for one track of skiing only) Interpretation and Education: to provide opportunities for education and interpretation without jeopardizing the park's natural character. The City and School District should develop programs for a variety of potential users groups, including: • school children of all age groups. • individuals and families. • seniors and special populations. The park should also allow for "passive" educational opportunities so that an individual can gain knowledge in an informal manner. This passive education would include such things as interpretive signs, printed site maps as well as informational brochures, etc. General Issues Related To The Parks's Future Development Along with identifying the purpose(s) of the park, the Advisory Committee also identified a number of issues to address during the planning process. These included: • a general inventory/identification of existing plant communities and vegetation. • a need for a vegetation management program. • a need to provide wildlife habitat • a need for an interpretation program to identify and describe the various plant communities and wildlife. • a need to encourage the local school district and local civic groups to participate in the development of a comprehensive educational program to educate people (of all ages) about plant communities and wildlife. • the need to maintain some form of site access and control. Potential uses of the park which could damage it included: general overuse, free -roaming domestic animals attacking wildlife, motorized vehicles entering the park, and other "nuisance" problems, such as kids starting campfires, smoking, drinking, littering, etc. Uncontrolled access also allows a convenient "thoroughfare" from the west side of the park to the high school area. • the need to define more clearly the purpose of the internal trads. The Committee expressed concerns about the need to reduce the width of the trails, the desire for woodchip trails, and limiting the grooming of cross-country skiing trails. • the need for additional parkin The Committee considered the parking lots for Schwarz Pond Park and Rosemount High School to be too far away and often unavailable to potential users of the park. Carrolls Woods Nature Area 2 City of Rosemount • the need for additional site amenities such as benches, signs, observation blinds, bridges, etc. • the need to identify and capitalize on the opportunities inherent in park's proximity to Schwarz Pond Park and Rosemount High School. • the need for neighborhood recreational facilities to service the recreational needs of existing and future neighborhoods to the west and north of the park. Note: this was identified within the overall park system plan for the City. • the possibility of including a prairie preserve area within the park. • the need to address safety issues (personal and physical). Addressing these needs provides the direction and basis for the entire master planning process. Alternative Concepts Three alternative concepts explored different boundaries for the park and illustrated different management techniques and relationships between physical uses of the site. These concepts respond to the issues listed above in the Development Program. Figures I, 2, & 3 illustrate three alternative concepts for the park. After considerable debate, the Advisory Committee selected Concept #3 (Figure 3) because it: • responded to the criteria as set forth in the development program. • provided a visionary approach to the park's future development. • allowed for more diversity in plant communities and wildlife species than the other concepts. Based on these findings, Concept #3, along with the development program, was used to define the study area and provide the basis for the continuation of the master planning process. Site Inventory Site inventory identifies the existing characteristics of the proposed park area (including geology, topography, drainage, soils, and vegetation). Based on Concept Plan #3, the study area was broken down into four adjacent parcels of land, of which Rosemount currently owns two. The other two parcels would have to be acquired through parkland dedication, direct purchase, and/or State grant programs. Figw 8 - Site .Analysis identifies four parcels within the study area: • Parcel A. includes Carrolls Woods as defined by its current (1991) boundary (45 acres). Acquired by the City through a LAWCON grant in 1976 for passive use, nature preservation and environmental education. • Parcel B: includes the part of Schwarz Pond Park which lies west of the north -south asphalt trail (e.g., west of the existing ballfield). This would include the pond itself (31 acres). The parcel is already owned by the City. • Parcel Q is an area which lies between Carrolls Woods and an existing gasline easement north of the park. This parcel is currently used for pasture land and is not owned by the City (15 acres). • Parcel D: is an area west of Schwarz Pond, north of Parcel C, east of a dominant ridge line, and south of a future collector street. This parcel is also currently used for pasture land and is not owned by the City (7 acres). Geology, Topography, and Drainage Thousands of years ago the climate of Minnesota warmed and the glacial ice which covered Rosemount began to melt. As the glaciers receded northwards, they deposited huge amounts of debris which had been carried in the ice. The deposits of sand and gravel and boulders, often over one hundred feet thick, are known as terminal moraine. The topography of the terminal moraine is rolling with steep hills, ridges, and landlocked depressions. Some level areas do exist at the base of slopes, in saddles and depressions, and on hilltops. The slopes of Carrolls Woods are mostly hot, south- southwest facing slopes. The Schwarz Pond parcel is a hot west -facing hillside. Parcel D has mostly north -facing slopes and the most moderate topography. Parcel C is a Carrolls Woods Nature Area 3 City of Rosemount series of ridges running north to south with steepest slopes facing east and west. Glaciers determined the landscape of Carrolls Woods and set up the drainage patterns which still exist today. Figure 4 - Drainage Pattenrs illustrates the site's current drainage patterns. These patterns are critical to the formation of soils and the subsequent development of plant communities. In Figure 4 - Drainage Patterns, the thick dashed lines mark the high points of the property and the boundaries of the watersheds. Water flows in opposite directions on either side of these lines. It is interesting to note the north -south pattern of ridges within the study area which mark the direction of receding glaciers. Because of the steep slopes of these ridges, the watersheds would tend to drain rapidly after a heavy rain. Since the watersheds are small, their lowpoints would not collect much runoff. Even so, one would expect to find wetlands in the several landlocked depressions on the property unless the soils are porous. Soils After the glaciers melted, weathering forces began to act upon the rock and debris left behind and started to form soils. Soils and slopes are intrinsically related. Slopes affect the degree of wind and water erosion, the rate at which moisture is absorbed and retained, and finally in the amount of sunlight reaching the ground. These factors in turn affect the growth of vegetation and the subsequent development of soil strata called a profile. Any management program should begin with an examination of the area's soil profiles. Soils offer an explanation for existing plant communities and affect the success of any planting restoration efforts. Figure 5 - Slopes and Soils shows that the study area is generally a dry site. No clay soils are present. Most of the soils are sandy or silt loams with moderate to steep slopes. This means water either runs off rapidly or percolates through rapidly. The subsoils are usually composed of several feet of sand and/or gravel. Depressions on the site are silty loams and poorly drained; these soil types make up a very small percentage of the total acres of the study area. Figure 6 - Soil Quvncterirtics explains the possible uses of each soil type found within the study area. The Dakota County Soil Survey states that the hillsides of the study area are generally most suited to woodland or prairie/ pasture/hay. Tilling is often difficult. The Soil Conservation Service recommends using drought resistant species on the most of the hillside soils. Vegetation 150 years or so ago the Rosemount area was predominantly oak savannah and prairie. Prairies are communities dominated by grasses and forbes. Oak savannahs consist of isolated oaks or small stands of oaks surrounded by a sea of grasses and wildflowers. Both plant communities are dependent on fire for continued existence. The savannahs, with their open vistas and groves of beautifully -formed craggy oaks, were particularly attractive to European settlers who were reminded of the parklands of their home countries. As the settlers turned the savannahs into home sites and farms, they also suppressed the fires which are so critical to the continued existence of the prairie and oak savannah communities. In the absence of fire, woodland species invaded uncultivated savannahs and prairies. In the full sunlight between the established Bur Oaks of the savannahs, Black Cherry, White Oak and Red Oak sprouted and grew. Sun -loving shrubs such as Hazelnut, Sumac, Gooseberry and Raspberry also invaded. When wildfire was suppressed, American Elm, Boxelder, Hackberry, Green Ash began to take hold. Under their canopy, the more shade -tolerant shrub species such as Elderberry, Dogwoods and perhaps Arrowwood and Nannyberry Viburnums grew. Within 50 years of the arrival of settlers, the savannahs and prairies of Rosemount had changed dramatically. In addition to suppressing fire, the European settlers also brought with them plant diseases and non-native shrubs and trees which sometimes out -competed native species. 25 years ago, American Elm probably dominated the tree canopy of Carrolls Woods. Since then almost all the American Elm has died of Dutch Elm disease and has left the central portion of the 45 acre parcel with a very sparse canopy of trees. Common Buckthorn (Rhamnus cathartica), a particularly aggressive non-native shrub, has invaded the property and has virtually taken over the understory. Tartarian Honeysuckle and woody vines have also been aggressive invaders. Fortunately in the last decade the Tartarian Honeysuckle has died out because of aphid attacks and concerned citizens of Rosemount cut and reduced considerably the vines strangling many canopy trees. Today the canopy of trees in Carrolls Woods is composed of the following species: Boxelder (Acer negundo) Green Ash (Fraxinus pennsylvanica) Black Cherry (Prunus serotina) Hackberry (Celtic occidentalis) Red Oak (Quercus rubra) Northern Pin Oak (Quercus ellipsoidalis) Bur Oak (Quercus macrocarpa) Carrolls Woods Nature Area 4 City of Rosemount White Oak (Quercus alba) Silver Maple (Acer saccharinum) Cottonwood (Populus deltoides) Aspen (Populus asp.) Boxelder and Green Ash are the most common trees of the uplands. Black Cherry and oaks are also quite prevalent with some beautiful stands of mature individuals scattered throughout the site. Several Silver Maple dominate the moist lowlands of the site. One enormous Cottonwood grows along the trail which runs across the southern edge of the property. Small mature stands of aspen are scattered throughout the uplands. Aspen are short-lived in a forest because they are intolerant of shade. They may seed in or root sucker into openings, but as the canopy closes in, they will begin to die out. Ecologists and foresters examine the understory of a forest to determine the future of its canopy. The understory of Carrolls Woods and the forest west of Schwarz Pond has a rather depressing story to tell. Barring human intervention or natural catastrophe (fire), Carrolls Woods will succeed to an almost pure stand of impenetrable Buckthorn with some Boxelder as the existing canopy trees die out. There are almost no seedlings of oak or cherry present in the 45 acres except in small openings with full sun and no Buckthorn.' Occasional saplings of Green Ash and Hackberry are present but even they are rare. Shrub species other than Buckthorn are also uncommon. Occasional Elderberry and Prickly Ash are scattered throughout the site. The ground layer of Parcel A (Carrolls Woods) shows quite a diversity. Although not closely inventoried, Jack - in -the -Pulpit, Trillium, ferns and mosses are present in various areas of the site. These species indicate moist or mesic microclimate conditions and need shade to survive. Nettles, gooseberry, raspberry and seedlings of the ever- present Buckthorn are common along paths and in openings where there is full sunlight. Parcel B (part of Schwarz Pond Park ) consists of a hot west -facing slope which leads down to the pond. The slope is covered by a well-established canopy of Northern Pin Oak, Red Oak, White Oak and Black Cherry with a dense understory of Buckthorn. The eastern and northern shores of the pond are primarily open with young successional woodlands of pioneering species (aspen, Boxelder, and willow) and stands of sumac. Parcel C is a open, rolling site with one very small remnant of prairie. The topography is spectacular and interesting. It is currently used as sheep pasture. Parcel D is a open, rolling site with some fairly level topography. It too is used for sheep pasture. General Perceptions of Vegetation It is clear that Rosemount citizens are very fond and protective of Carrolls Woods and the Schwarz Pond property. Most people enjoy strolling under a lush, cool canopy of trees in the summer. They appreciate the beauty of the woods as they are now and are more interested in sensory experiences rather than how "pure" the ecological communities are. Ecologists, on the other hand, see Carrolls Woods through different eyes: as a forest of mixed hardwoods considerably degraded by Buckthorn and with a limited future. The short-term management objectives for the two views of the woods are opposite; the first demands little disturbance of existing conditions, the second demands heavy intervention and manipulation to maintain ecological diversity. Left on its current course, the canopy of mixed hardwoods will continue to die out and be replaced by Buckthorn which effectively shades out any tree seedling or sapling. In the not -to -distant future, Carrolls Woods will evolve into a dramatically different place: a sea of Buckthorn. The trails will become corridors through a dense mass of 20- 25 foot Buckthorn with no cool shade and no sensory diversity. At this point in time the two opposite approaches for forest management will become similar, demanding intense intervention to recreate the canopy. The perceptions of the public, rather than the ecologists, are critical to the acceptance of the Master Plan for Carrolls Woods Nature Area. Brauer & Associates Ltd. recognized this and inventoried the vegetation of the four parcels in a manner which would address these perceptions. The wooded areas of the study site were divided into six forest types (see Figure 7.- Vegetation). Each type has a different type of canopy and understory and very different visual and sensory qualities. Site Analysis Site analysis uses inventory information to make judgements about the site. Site analysis identifies potential opportunities and constraints for development. Access and Control• Users of Carrolls Woods currently enter the 45 acre parcel from several points. The asphalt trail running along the eastern border is the most sanctioned entry point. Several trails of varying widths enter the woods off this trail. Another main entry point is Carrolls Woods Nature Area 5 City of Rosemount at the bottom of a steep hill in the southeast comer of the property. There are three points of entry along the west border. The Advisory Committee felt strongly that the number of access points into the park be limited. The Committee also felt that entry points will be needed on the north, west, and east side of the property. Internal Tram System: Many trails crisscross Carrolls Woods. They vary in width, degree of steepness, and quality of the surface. The Committee did not want to create new trails unless necessary and felt some trails should be eliminated or realigned. Currently, individuals often use the trail along the southern edge of the woods as a way to get from the areas west of the park to the areas east of the park, particularly Rosemount High School. As residential development on the_ west side of the park continues, use of this trail will likely increase. The Committee felt that this type of "thoroughfare" was not in line with the park's natural character and therefore they did not want any trails developed through the park for this specific purpose. Figure & Site Analysis highlights those trails which should be eliminated because they are redundant, too steep, too wet, or because they serve undesirable access points. Site Amenities: There are no benches, signs, or other site amenities in Carrolls Woods. There are many opportunities for these built facilities which should be added once restoration efforts for the plant communities are underway. Parking: Visitors coming to Carrolls Woods by car must use the parking lots for Rosemount High School or Schwarz Pond Park. These are so far away from the woods that it takes a good walk just to get to the park. Also the lots are often full. Topography and existing development around the perimeter of the site presents a challenge to the designer of a parking lot which requires level grades. Parcel D has the most level grades for parking. The two lots owned by the City in the southwest comer are inadequate in size to serve the future parking needs of the park. Neighborhood Recreational Facilities: Parcel D is an open, rolling area with some fairly level topography. It will be immediately adjacent to a proposed collector street. In the near future the areas north and west of this parcel will likely be developed for residential housing. These communities will need neighborhood recreational facilities within walking and biking distance. Parcel D has the acreage and enough level topography for these recreational facilities. Schwarz Pond. The pond within Schwarz Pond Park is a significant natural area and has value as wildlife habitat. It has limited value as a recreational lake. The woodland east of the pond has many lovely oaks and cherry trees. This area should be included in the park. Parcel C. With its dramatic topography and open vistas and its existing use as a pasture, this area is perfect for prairie and oak savannah restoration. Near the northern border of Carrolls Woods is a mature, beautifully -formed Bur Oak and a nice stand of smaller Bur Oaks. The form of these trees indicates the area could have once been a savannah. Woodland Vegetation: the inventory of vegetation in the study area indicated six types of forest. Each type will have a different management approach (defined in the Vegetation Management Program). Control of Buckthorn will be critical in all areas. Fi urr 8 Site Analysis simplifies the areas of forest for the purpose of management. • Degraded Woods: sparse canopy; isolated mature trees @ 150-200+ feet apart. Understory is a impenetrable wall of Buckthorn. • Open Canopy: mature trees are much more common and closer together. The understory is still fairly dense Buckthorn. . • Pleasant Woods: mature trees form a good canopy with some Buckthorn in the understory. • Lowland forest: these small areas are disturbed frequently by groundwater or wet soil conditions. Gigantic Silver Maples and Cottonwoods are common with an ground layer of nettles. • Successional: young trees, dense understory with a variety of species. Master Plan The Master Plan is a direct outgrowth of the accepted Concept Plan and represents the design solution that best responds to the development program and the site inventory and analysis. Figure 9. MasterPlan illustrates the results of the planning process for Carrolls Woods Nature Area. This graphic: • clearly defines the park's property boundary (consistent with Concept Plan #3) to ensure diversity of plant communities and wildlife habitat. • locates and sizes all facilities and site amenities. Carrolls Woods Nature Area 6 City of Rosemount • establishes appropriate plant communities which are the basis for wildlife habitat. The following text describes each physical element of the Master Plan and explains the reasoning behind the design. Access Control It is clear that Rosemount citizens feel the need for an undeveloped area where they can stroll and appreciate the beauty of nature. A number of recent studies have documented this need, which is likely to become more acute as the community continues to grow. Likewise, Rosemount schools will continue to need a place for environmental education and interpretation. It is important to recognize that the park is different from other community -type parks: its environment is more fragile and complex. Human activity and intervention can easily change the character and overall quality of this natural area. To insure the long-term preservation of the park, it will be critical to protect the park from the pressures associated with urban development. These pressures raise the issue of control and access. Currently Carrolls Woods has an unfenced perimeter. Although it is not easy for the average citizen to reach the park (parking is far away), it is easy to enter the woods at any number of locations. There is no perceived stewardship of the park. This lack of control works fairly well with the existing level of use of the park and with the land uses which currently surround the property, i.e. farmland to the west and north, the high school to the east, and homes to the south. Without a doubt, this casual approach to control is ideal and very appropriate in the near future while the community begins managing the plant communities of the park and developmental pressures around the park remain limited. However times are changing in Rosemount. Within the next decade residential development will likely occur to the north and west of the park. As undeveloped land disappears from the community, citizens will have a greater desire to spend time in a nature preserve. The City will want to make access to the park as a community resource easier for the average citizen by providing parking and trails. Undesirable activities within the park will increase as the population of Rosemount grows. Free -roaming cats and dogs will disturb wildlife. Small footpaths begin to increase in width as people make their own shortcuts. Students will cut through the park to get to the high school. Unauthorized uses (parties, campfires) and nuisance and vandalism problems tend to increase in areas that the public does not perceive as controlled. All these pressures will degrade the woods as a natural area. At some point in the future the park will likely have to be protected by some means other than the goodwill of Rosemount citizens, namely a fence around the perimeter. This circumstance is certainly not unique to this park. Virtually all nature centers with limited acreage in the Twin Cities metropolitan area fence their property. The fence becomes not only a physical barrier but a psychological one as well. It makes a statement to the community that the area is special and needs protection. By limiting the number of gates, the City can control the hours and season of use (if desired) and most undesirable activities. Gates are also opportune places to present rules and interpretive information. Fences discourage unauthorized uses, encroachment, and trespassing on private property. Specifically, the fence is intended to: • clearly define the parks perimeter and make a statement as to its intended purpose. • protect the park from developmental encroachment. • restrict site access to pedestrians and maintenance vehicles and thereby limit trails. • control free -roaming domestic animals. • prevent motorized vehicles and bicycles from entering the park. • control "nuisance" problems, such as kids starting campfires, smoking, drinking, littering, etc. • prevent the park from becoming a convenient "thoroughfare" between the developing part of the City to the west and north of the park and the schools and major community center. After considerable discussion and debate, the Advisory Committee recognized that the need for a fence may become a reality at some point in the park's future and that a fence should be included in the Master Plan. However, the Committee also felt that there is no compelling reason at this point to have the fence high on the priority list for development. Instead, the Advisory Committee should review on a periodic basis the need for a fence, along with other development considerations. The Committee should use as criteria the items listed above to determine whether or not the fence is needed. If the site begins to degrade from unauthorized uses and these uses cannot be effectively controlled by other means, the City will have to strongly consider installing the fence to protect the site. Initial reactions to the idea of a fence around the park may be that it is intimidating, unnecessary, and ugly. However, this does not have to be the case. If installed properly, a fence can be relatively unnoticeable. Vegetation will screen Carrolls Woods Nature Area 7 City of Rosemount it. Psychologically, the fence becomes a barrier to the human world that, in the not so distant future, will encircle the park. Those who are involved in the park's future development should go out to any one of a number of fenced nature areas within the metropolitan area and see for themselves how little a fence affects the park's atmosphere. Should a fence become necessary in the future, it should be six foot in height. Galvanized chaird nk fence of a suitable commercial grade is the most commonly used material because it is relatively economical to construct and reasonably durable. As the Master Plan illustrates, the fence is intended to essentially follow the park's property boundary. To limit its visual impact and make it as unobtrusive as possible, the fence should be set back from 0 to 15 feet from the property line and be screened by surrounding vegetation. This is particularly true in the more heavily wooded areas of the site, where the fence's alignment will be dictated as much by the existing vegetation as by the property boundary. Care should be taken during the fence's installation to limit disturbance to the existing vegetation. Installing the fence in the late fall when plant life is largely dormant and avoiding existing trees will minimize damage to the park. In open areas, planting vines and shrubbery will help screen the fence from view. In areas where the fence will be adjacent to existing residential properties, the City should make homeowners aware of the fence's proposed alignment prior to its installation. Some homeowners may prefer the fence along the property line rather than set back and screened from view. The Master Plan identifies four pedestrian gates to provide access into the park. The tum -style type, pedestrian -only gate in the southeast comer of the site will serve the already -developed residential "core" of the City as well as the school. This entrance should be very simple and unobtrusive, with an asphalt trail providing access from the existing roadway down to the gate. The access shown on the northwest comer of the site will serve future residential areas to the west and northwest of the site. This gate should also be a tum -style, pedestrian - only gate. To access the gate from the future residential street west of the park, the City needs to acquire a 24' wide easement to allow for grading, screening and building a pedestrian trail. The Advisory Committee debated at length the issue of whether or not to provide a pedestrian access in the southwest comer of the site. After lengthy discussions and considerable public input, the Committee felt that a gate in the southwest is appropriate and necessary to serve both the current and future residential areas to the west and southwest of the park. As with the other secondary gates, this gate should also be a turn -style, pedestrian -only gate. To access this gate from the residential street west of the park, the City needs to retain a portion of the park dedication land directly adjacent to this comer of the park. Retaining a 24' wide strip (e.g., easement) to allow for grading, screening and building a pedestrian trail should be adequate. The remainder of the park dedication land is of limited future value (for the purpose of this master plan and providing access to the park) and could be, at the discretion of the Parks Committee and City Council, sold - off for development, with the proceeds ideally being used for future development within the park. With respect to the access in the southwest comer of the site, adjacent property owners and the Committee were very concerned about preventing a "thoroughfare" from being developed through the park along the southern property line. In this instance, "thoroughfare" means either a high volume asphalt -type trail and/or a developed roadway. It is not the intention of the southwest comer access to serve this type of development in the future. The only intention (within the context of this master plan) is to allow residents to the west and southwest the opportunity to enter the park itself, and not to serve as a direct link to other areas of the community. The main entrance gate on the north side of the site will serve not only those walking to the site but school buses and those driving to the site from other areas of the community. This entrance should be simple and natural in design and make a statement that the visitor is entering the nature area and a protected environment. This gate should be limited to pedestrians. A gathering area outside the gate should accommodate a group of 25 people (a class of students). This area will include benches and perhaps a kiosk. Inside the gate, a kiosk provides visitors with a map of the area and a brief description of what might be seen. The displays should include photos, graphics, and written text to describe and illustrate the park's features. The kiosk should have a leaflet box to dispense park maps/guides. The Master Plan also includes a number of gates for maintenance vehicle access. The primary access is near the main entrance gate on the north side of the park. This access should serve most maintenance needs once the park is fully developed. A second access is shown near the existing hockey rink on the southeast side of the site. This access will probably serve as the primary maintenance access until the park becomes more fully developed. This gate can also be opened in October for participants in the Haunted Woods program. Third and fourth accesses are shown near the pedestrian entrance on the northwest and the southwest. These are intended to be used on a minimal basis and only to service areas of the park that cannot be effectively serviced through other gates. The Advisory Committee also discussed the twenty foot easement near the southeast comer of the site. Given its Canolls Woods Nature Area 8 City of Rosemount relatively steep grades and the current lack of use as an access to the park, the Advisory Committee felt no action was necessary at this time. However, the members of the Committee did agree that the issue should be reviewed again prior to installing the fence, should the fence become a reality in the future. Internal Trail System An internal trail system which meanders through the park is intended to move people through the nature area with a minimum impact to the environment and yet insure that they receive a quality outdoor experience. Although the primary objective of the trails is to link together the various plant communities, the system should also be developed to take advantage of the varying topography, views, and vistas. The trails should provide visitors with a variety of perspectives and experiences. Yzgum 10- Typical Tial Cross Seddon for GVTOUs Woods Nature Area shows the suggested design for internal trails. In order to keep the experience of the woods as intimate as possible, the width of the trail should ideally be six feet with a one foot maintenance strip on each side. Although this would be ideal, it should be recognized that the trail widths will have to be somewhat wider in at least the near future since the City's current maintenance equipment cannot economically maintain an eight foot wide trail corridor. Instead, a ten foot wide trail corridor is a more realistic expectation at this time, with the width potentially being narrowed over time as new equipment becomes available. The surfacing material should be: • compacted crushed aggregate (suitable for handicap accessibility) on the primary loop within the wooded and prairie/savanna areas. • woodchips on the auxiliary and secondary trails within the wooded areas. • mowed grass on the auxiliary and secondary trails within the prairie/savanna areas. Because one of the primary development objectives is to limit disruption to the existing mature vegetation, the Master Plan uses existing trails within the park as much as possible. However, some changes will be needed where existing trails do not serve a future purpose and/or where their grades are excessive. In some cases, trails will be eliminated because they serve undesirable access points. Since the existing trials vary from four to twelve feet in width, they will require some reworking, much of which can begin immediately. Also, even though the trails shown on the Master Plan may follow existing alignments, they may need redesigning to make sure that they are safe and maintainable. The new trails shown on the master plan supplement the existing trails. All of the trail alignments, both old and new, should give the user a quality experience of the park with many options for routes to walk. The exact location of each trail must be established in the field during design development (i.e. the "next step" in the planning process) to take advantage of the opportunities afforded by the site. In other words, the trail alignments as illustrated on the Master Plan should be considered approximate and not absolute. As with the existing trails, new trials should be designed to make sure that they are safe and maintainable. Carrolls Woods Nature Area should be a community resource in the winter as well as in the spring, summer and fall. Snow and ice can be barriers to using the trails. The Advisory Committee felt that a single groomed track for cross-country skiing would allow people to experience the woods in winter and would not detract from the quality of the environment. A single pass through the woods by a snowmobile trailing a pair of weighted skis would create a narrow trail for skiers which would not damage surrounding vegetation. Site Amenities Enhancing the perceptions and experiences of park visitors through the careful use and placement of site amenities is important and will greatly affect the overall success of the park as a public resource. Site amenities are the built features which increase the comfort/access of the park users. As with the trial alignments, the exact locations of the various site amenities must be established in the field during design development to take advantage of the opportunities afforded by the site. All of the site amenities should be natural and simple in design and as much as possible blend into the environment that surrounds them. Interpretive Nodes and Signs: interpretive nodes are places along the trail with low profile kiosks. These kiosks have interpretive panels and exhibits which are fun and easy to read with good graphics and minimal text. Interpretive nodes are typically located near benches and other site amenities (i.e. decks, docks, etc.). Located along the trails, unobtrusive interpretive signs will identify the various plant communities and wildlife species and augment the interpretive nodes. Benches: should be provided to take advantage of different views and site features, ranging from quiet, intimate spots to wide open vistas. Again, benches can be installed at Carrolls Woods Nature Area 9 City of Rosemount interpretive nodes if appropriate. A Floating Boardwalk: located in the wet prairie area gives park users an close -hand experience of the tall grasses and Forbes of the wet prairie. Environmental Education Dock: provides an educational opportunity for school children so that they can study pond life and take water samples, etc. In addition, the shop students from the local schools could help construct the dock as part of their classes. Pond Overlook Dock provides park users with a pleasant place to sit and view the pond. Two benches allow seating. Pond Observation Blind: provides park users with an opportunity to view waterfowl activities. If properly designed, the blind hides people whose presence and movements normally scare the waterfowl away. The blind is on the edge of the pond and surrounded by vegetation to help screen it from view. An elevated catwalk from high ground provides an interesting access to the blind. Wooden Bridge Across Woodland Pothole: is a simple structure with a railing that crosses the woodland pothole at a narrow point. 'Lookout" Tower. gives park users a birds eye view of the area and is another opportunity for a visitor to observe nature in relative anonymity. A height of thirty feet should elevate the tower platform above most of the understory trees. Woodland Deck is another simple structure with benches designed for resting and observing nature. Cottage House for Interpretive Displays, Storage, Meetings, Restrooms, Etc.: is a simple building to serve the listed uses. The building should be sited near the main entrance gate at the edge of the savannah. It should have a low profile and use natural materials to blend into the surroundings. A patio outside the building allows visitors a place to sit and observe the prairie. Entrance Drive and Parking Since the entrance drive is the first contact that visitors have with the park, it should be located in a manner which compliments the existing topography. The entrance drive will tie into a future collector street which is likely to be developed north of Schwarz Pond Park. The parking lot at the end of the entrance road should be sized to prevent overuse of the park but large enough to allow a bus to turn around. Ideally, the lot should be paved with asphalt to minimize long-term maintenance and dust. Since the entrance drive and lot are outside the nature area itself, they will technically be part of Schwarz Pond Park. Users of the picnic areas on the west end of the park will probably park in the lot. A lot for 35 to 50 spaces plus several bus parking stalls will probably be sufficient to satisfy the parking needs of the users of both the nature area and Schwarz Pond Park. However, as actual design and construction of the lot and entrance road become reality, the City should closely examine potential demand for parking and size the lot accordingly. Neighborhood Recreational Facilities The city-wide park system study identified the need for neighborhood recreational facilities for this area of the community. Parcel D is an open, rolling area with some fairly level topography and is adjacent to the proposed collector street. Parcel D is the best site within the study area for neighborhood recreational facilities. Since it is the policy of the City to include input from area residents when determining what recreational features will be in the park, the facilities shown on the plan are for reference only and need to be confirmed (or changed) when development actually occurs. These recreational facilities should be connected by trails to the community -wide trail system. Schwarz Pond Park The pond within Schwarz Pond Park is a significant natural area which could add greatly to the diversity of plant and wildlife habitat within the park. The area east of the pond can provide excellent waterfowl nesting habitat if current mowing practices are discontinued and the City restored the area to prairie. Fencing (should it become necessary) and wildlife plantings along the asphalt trail would keep domestic animals from disturbing nesting areas. The woodlot west of the pond is a beautiful natural area which justifiably should be included and managed as part of the park. Its location next to the pond enhances the wildlife value of both areas. The pond is a ecological community which' has important education and interpretive possibilities. The City and Rosemount School District should monitor the pond's water quality and protect its integrity as a resource by establishing water quality guidelines. The Master Plan shows a number of amenities within Schwarz Pond Park and outside the nature area. These amenities include two scenic overlooks and a number of Carrolls Woods Nature Area 10 City of Rosemount picnic areas near the parking lot. The overlooks should be mowed areas or decks with benches overlooking the pond. The picnic areas should also be simple in design, with a number of picnic table and grills and perhaps a small - group picnic shelter. External Trails External trails provide access to park entrances and play an important role in how well the park ultimately serves the residents of Rosemount. The four entrance gates should tie into the community -wide trail system which is defined within the City's Comprehensive Park Plan and Development Guide. The existing asphalt trails on the east side of Carrolls Woods and Schwarz Pond will ultimately be outside the (fenced) nature area. The trail link to the southwest entrance can easily tie into the already established community trail along the 142nd Street West. Since the trail does run across school property, the district would have to be involved in determining its exact location. The trail links to the northwest, southwest, and main entrance gates are also very important and should be developed in conjunction with future roadway and subdivision development. The Advisory Committee and City should review access concerns periodically and in conjunction with planned development in the area to insure that trail access opportunities are not lost along the way. Vegetation Management Program The Vegetation Management Program identifies the management approaches and procedures to guarantee the ecological diversity of the park so that it will be a treasure and resource for future generations. In order to maintain long-term ecological diversity and integrity, the wooded portions of the park must be managed and improved and the open areas need to be restored to prairie or savannah. Vegetation management programs can be geared to create five different types of sensory experiences of the park and adjacent parcels. These sensory experiences also represent different ecological communities. Dense canopy. 75%-95% overstory coverage with sparse understory (relatively open). Sensory experience: lush, shady, cool. Open feeling under a ceiling of trees. Long views through woods. This type of feeling is most common in a lowland forest or in a mature Sugar Maple -Basswood forest. The latter requires moist (not wet), protected and semi -shaded conditions. Neither Sugar Maple or Basswood grows naturally on the site; introducing these species would create an anomaly or artificial condition. It might be beneficial to attempt to create this woodland community for an environmental education program. Moderate canopy. 40%-60% overstory coverage with moderately dense understory. Cool shade dappled by sunlight, limited views. Common in a mixed hardwood forest. This sensory experience is probably most popular among Rosemount citizens and already exists along most of the trails and along the northern edge of Carrolls Woods. Sparse canopy. less than 15% overstory coverage and dense understory. Without fire, this community is dominated by aggressive pioneering plants. The sensory experience in summer is hot, walled -in, transitional, young, not as appealing as types listed above. This condition is frequent in the center portion of the site with dense Buckthorn. Savannah: mostly open with occasional spreading individual trees or small stands of stunted trees. Intense sunlight with pockets of shade. Bright, hot, open, windy in summer. In winter, savannahs feel exposed and cold; snow melts away quickly especially on south -facing slopes. Attention focuses on landform and trees. Oak savannahs are rare plant communities today. Prairie: open, hot, often uncomfortable in the summer unless there is a good breeze. Pleasant in spring and fall. Windy and unprotected in winter; snow disappears quickly on south -facing slopes. Attention focuses on landform, the texture and color of grasses, the washes of color from wildflowers. Prairies can grow in a variety of situations: from wet, poorly drained areas to dry, barren hilltops. Available water and the depth of topsoils determine which species of grasses and wildflowers will best grow. Existiung Site Opportunities. The two wooded parcels within the study area (Parcels A & B) currently provide opportunities for nature lovers to enjoy two types of Minnesota forests: the dry upland forests of mixed hardwoods (oak, cherry, ash, Hackberry) and lowland forest of boxelder, cottonwood and silver maple. Parcel A (Carrolls Woods) has one north -facing slope which could provide the cooler microclimate conditions needed for a moist upland forest (Sugar Maple -Basswood). Parcel C is an open, rolling site with one very small remnant of prairie. The topography of this parcel is spectacular and interesting and has great potential for prairie and oak savannah restoration. If possible, Carrolls Woods Nature Area 11 City of Rosemount Rosemount should acquire enough land to control the viewshed (Le. to the tops of ridge lines) and should also consider scenic easements. Aesthetics suggest softening the straight line boundaries between woods and pasture (prairie) that exist along the northern boundary of Parcel A (Carrous Woods) and along the eastern border of Parcel B (Schwarz Pond Park ). For this reason, some of the oak woods along the western edge of Parcel B be restored to savannah. Since savannah is more easily restored than recreated, Rosemount should treasure the savannah type oaks (Le. 100-150 year old Bur Oaks with rounded canopies) which exist within the study area. Management Objectives. The management objective of woodland management within the nature area is to maiptain diversity within the existing woodland communities. This will insure that the future generations will be able to enjoy a forest of trees rather than a monoculture of Buckthorn. Woodland management will be a tricky issue for the City. The Buckthorn infestation is so severe that removing it will devastate the forest for a few years until other species take hold. Unfortunately, there is no alternative if Rosemount citizens want to achieve the long-term goal for the park with ecological diversity. Phasing and public awareness/education will be critical to public's understanding of what is happening within the park and to their support of management efforts. The restoration of prairie and oak savannah should not create the same concerns as the woodland management program. The proposed sites for these communities are currently in pasture and restoration efforts will not appear to change the area so dramatically. Burning may present some problems, but again publicity and sensible scheduling will limit public concern. Vegetation Management Plan Kigum 11- Vegetation Management divides the park into several zones. Each zone is described by. • a letter/number code. • a phase number. • an approximate acreage figure. The first part of the code describes the ecological community (e.g. WO = Woodland - Mixed Hardwood, P = Prairie, S = Savannah, etc.). The second part of the code is an alphabetical letter which describes the method of restoring or managing the ecological zone. These methods are described in detail below. The third part of the code is a number which describes the priority of the zone for management/restoration. Zone 1 is the highest priority within a particular ecological community and Zone 9 is the lowest. Ytgure 12 - Vegetation Management Phasing Progr+wn describes phasing in more detail. Prairie Areas (Method A or P -A-#) The City should hire a firm specializing in prairie restorations such as Prairie Restorations of Zimmerman, Minnesota or Prairie Nursery of Winona, Minnesota. These firms offer advice and a range of services including burning and planting. Make sure the chosen firm uses prairie seed collected within a 200 mile radius of Rosemount. Non-native seeds can be aggressive, resulting m one or two species dominating the site. Mow fire breaks around the perimeter of the future prairie areas. The experts from the prairie restoration firms will recommend the best technique for restoring the prairie grasses and forbes appropriate to each particular microlite. The nursery may recommend burning the entire prairie - designated area to see what surprises the seed bank in the soil holds. Prairie seed can lie dormant for years in the soil. Next, the experts may recommend one or two general or local applications of Round -Up. This herbicide will kill all vegetation. The next step is to use a Truax Drill to plant seeds of prairie grasses. The following year the restoration firm may mow and plant by hand forbes or wildflowers (1000/acre). In the beginning a prairie should be burned every year in order to eliminate weeds and the woody plant materials which naturally invade an open site. Burning also creates spectacular wildflower displays. Once established, a prairie should be burned every 3-5 years. Although other techniques, such as mowing, can be used in the restoration process, burning is typically the most effective (and natural) and should be used when at all possible and permitted by the City. Communicating with nearby residents about the burning process and burning under ideal conditions will go a long way toward minimizing or mitigating the negative aspects of this procedure. Recreated Oak Savannah (Method A or S-A-#) In these designated savannah areas, mow 10-15 foot fire breaks around the edges to prevent the fire from jumping into the adjacent woods. Carrolls Woods Nature Area 12 City of Rosemount Hire a prairie restoration firm. Restore prairie. Once the prairie community is established, tree spade in small Bur Oaks ( 2" -3" diameter at breast height). Plant the Bur Oaks in clusters or as isolated species 150-200 feet apart. The City can reduce costs by transplanting Bur Oaks from other City property or by donation from private property. This transplanting can occur over a period of years. All plant stock should be obtained from a local source to insure its hardiness. Examine the transplanted trees after one season. If they are doing well, leave them be. If they appear sick, cut the trunks off around 6-12 inches above ground. The Bur Oaks should sprout from the base. After 2-3 years, select a main leader and prune off the rest. The Bur Oaks seedlings will need Tubex Tree Shelters (@$5.00 apiece installed) to protect them from deer browsing. Initially, a savannah should be burned annually. The young Bur Oaks need protection from the heat of the fire. Mow a 16 foot diameter circle around each oak to protect it from damage. Once sufficient shade is established, plant the forbes and grasses unique to a savannah community. Restored Oak Savannahs (Method B or S -B-#) Oak Savannahs are more easily restored than created from scratch. A few savannah type trees exist along the northern edge of the Carrolls Wood. These are Bur Oaks with well -formed rounded canopies; they look like they have always grown in the open rather than in cramped forest conditions. Mature Bur Oak have thick corky bark which makes them resistant to quick ground fires common to prairies. In the designated savannah areas, mow 10-15 foot fire breaks around the edges to prevent the fire from jumping into the woods. The City should also hire a prairie restoration firm to assist in restoration of prairie grasses and forbes within the savannah areas. In the fall cut and remove undergrowth (usually Buckthorn). Paint the herbicide Garlon on cut surfaces of stems. The next spring, bum. Because of lack of fuel it may take a few years to get a complete bum. Savannah - type grasses and forbes should start to reappear. After an area is burned, seed in handfuls of grasses and forbes (seeds and berries) appropriate to an oak savannah. The prairie restoration firm can provide some of these species. Others may have to be collected by volunteers from local areas. Initially a restored savannah should be burned every years. Once the understory of desired species is established, the burning can be done every three to five years and, eventually once every ten to fifteen years. Oak Woodland (Method A or WO -A-#) This restoration method is for degraded woods (see Figure 8: Site Analysis) with a sparse canopy or isolated mature trees @ 150-200+ feet apart. The understory is a impenetrable wall of Buckthorn. These woodland areas will be the most costly and exasperating to restore. This method of management is geared towards eliminating the dense understory of Buckthorn and replacing it with more desirable species. This is a multiyear process because Buckthorn is a prolific seeder. Year One: In the fall or winter, cut and remove adult Buckthorn (any stem over ; inch in diameter if possible). Treat the cut stems with Garlon. This phase will eliminate 90-95% of the Buckthorn biomass. It is extremely labor intensive (Rosemount may want to organize volunteer help. A person licensed to apply herbicides must be in charge of training and overseeing the volunteer help.) Year Two: Plant 75 saplings per acre. Plant Red Oak, White Oak, Black Cherry, and Green Ash. Use the Tubex 5' tree shelters for these saplings. These tubes will serve 3 functions: • protect the saplings from rodents and deer • create condensation which will help the saplings survive the drought -prone soils. • protect the saplings from herbicide sprays. After planting, use a foliar spray (such as Krenite .or Round -up) to kill off all the Buckthorn seedlings. These sprays will kill any green growing plant that they contact. Buckthorn remains green and growing in the forest 2-14 days after most native vegetation goes dormant in the autumn. This time may be the best time to spray in order to preserve as much non -Buckthorn understory vegetation as possible. Rosemount will need expert advice from the herbicide distributor as to timing of application (the window of opportunity varies from year to year and can be quite small). Year Three: Apply a foliar spray again to eliminate any remaining Buckthorn seedlings. Seed each acre with Canons Woods Nature Area 13 City of Rosemount acorns or plant oak/cherry seedlings (2000/acre). The DNR sells 1000 tree seedlings for $150. Acorns are not available commercially, collecting them could be a volunteer effort in early to mid August. One drawback for acorns is that not every year is a productive year for oaks to produce them. Subsequent years: Monitor the restored areas for buckthorn regeneration. Continue to eliminate either by cutting and applying Garlon to the cut stems or by using foliar sprays for pockets of infestation. Oak Woodland (Method B or WO -B-#) This management method is for pleasant woods (see Ylgure 8. Site Analysis) with a well-developed canopy of mature trees and a moderate Buckthorn understory. Management efforts should be directed at eliminating Buckthorn, especially the mature individuals and ones in the occasional openings in the canopy, and supplementing the planting especially in openings. Year One: Cut and remove adult Buckthorn (over 4 inch in diameter). Apply Garlon to cut stems. Replace the Buckthorn with tree saplings or shade -tolerant shrubs. Possible species: Common or Scarlet Elderberry (Sambucus canadensis or pubens) American Hazelnut (Corylus americana) Nannyberry (Viburnum lentago) Gray Dogwood (Cornus racemosa) Pagoda Dogwood (Cornus alternifolia) Round -Leafed Dogwood (Cornus rugosa) Serviceberry (Amelanchier canadensis) Gooseberry (Ribes cynosbati) Raspberry (Rubus strigosus) Prickly Ash (Zanthoxylum americana) Green Ash (Fraxinus pennsylvanica) Red Oak (Quercus rubra) Northern Pin Oak (Quercus ellipsoidalis) White Oak (Quercus alba) Black Cherry (Prunus serotina) Hackberry (Cells occidentalis) All plant stock should be obtained from a local source to insure its hardiness. If there are any large openings in these zones with solid stands of Buckthorn, eliminate using Method A. Year Two: Monitor these zones, cut and apply Garlon to any remaining Buckthorn. Continue to add shrubs and saplings if needed. Begin to enrich the herbaceous layer in shady areas with appropriate wildflowers. Oak Woodland (Method C) This restoration method is for north -facing slopes with an open canopy and a fairly dense understory of Buckthorn. For areas without canopy trees and heavy Buckthorn, use Method A. When planting, use the species listed below. For areas with canopy trees and some Buckthorn, use Method B. Species to plant: Sugar Maple (Acer saccharum) Basswood (Tilia americana) Ironwood (Ostrya virginiana) Black Cherry (Prunus serotina) Hackberry (Celtic occidentalis) Red Oak (Quercus rubra) Butternut (Juglans cinera) Black Walnut (Juglans nigra) All plant stock should be obtained from a local source to insure its hardiness. As the Buckthorn is eliminated and the canopy begins to fill in, enrich the forest floor with wildflowers called spring ephemerals. Lowland Woods (WL) These small areas of the site are disturbed frequently by groundwater or wet soil conditions. This community will not require much management except to prevent disturbance of the drainage systems and to eliminate infestations of Buckthorn. Successional Woods (WS) Successional forest: these areas are dominated by pioneering plants and have few mature trees and a dense understory of a variety of species. The only management needed for these areas is to control Buckthorn invasions. Woodland Pothole The area in the southwest comer of Carrolls Woods was once quite productive waterfowl habitat. In the last twenty years it has silted in and become dry enough for Silver Maples to grow. To make the area a pothole again, it must be dredged, regraded, and perhaps sealed to prevent water from seeping away. If possible the City should Can -oils Woods Nature Area 14 City of Rosemount construct a small siltation pond to filter all stormwater runoff before it enters the pothole. Once open water is provided, the bird (and animal) life will return. Schwarz Pond The fluctuations in water levels for this pond actually increase its productivity as a food source for waterfowl. Discontinuing mowing and planting prairie would improve this area as habitat for birds and animals. Some wildlife plantings along the fence will help screen it. The City or school should monitor water quality in future years. Wildlife Habitat Program One of the primary objectives for this park is to establish diverse wildlife habitat which provides food, water, and shelter for a variety of wildlife species. Although the pallet of plants included in the Vegetation Management Program for the park will provide habitat for several wildlife species, a wildlife management program will add extra components to improve the diversity of species using the nature area. A number of state and regional resources are available to help develop a wildlife habitat and management program. The Minnesota Department of Natural Resources (D.N.R.) have individuals with expertise necessary to: • evaluate existing habitat and its potential to support wildlife. • recommend habitat development programs to improve the habitat that is already present. • identify the bearing capacity of the park and ways to maintain a healthy wildlife population. The City should contact the D.N.R. Section of Wildlife prior to future development to insure that no opportunities are missed along the way. Based on the DN.R.'s guidelines, fifteen components of wildlife habitat are necessary to fulfill the major needs of most species. Eight of these components are plants and eight are structural or non -living components. Plant Components: • grasses/legumes • butterfly, bees, moth plants • hummingbird plants • summer plants • fall plants • winter plants • nut/acorn trees Structural Components: • feeders • water • dust beds/grit • salt • cut banks/cliffs/banks • brush/rock piles • snags • nest boxes By providing these components, the community will improve the chances of wildlife flourishing within the confines of this nature area. Cost Estimate and General Phasing Program Although certainly not an exact science, estimating or projecting the costs to develop this park is important because it provides the citizens of the community, governing bodies, and City staff with a basic understanding of the economic commitment necessary to put the park's Master Plan into effect. The estimated costs to develop the park will affect priorities for adding the various components and amenities and in deciding which ones are best accomplished through volunteer efforts versus paid contracts. The City and Advisory Committee should use the figures below only as 'benchmarks" to compare the relative costs of items and for budgeting purposes. Actual cost to acquire land and develop the Master Plan will depend a great deal on: • the actual land values at the time of acquisition. the actual construction costs at the time of development. • how much of the costs for development can be offset through alternative funding programs, such as volunteerism, grants, donations, etc. The cost estimates below are based on estimated land values in 1991 dollars (determined by the City) and typical development costs in 1991 dollars (as determined by industry cost -to -construct averages, i.e. what it would typically cost, on average, for a contractor to come in and do the work). Carrolls Woods Nature Area 15 City of Rosemount Park Land Acquisition Costs The Master Plan includes two parcels of land which the City does not currently own. The first parcel (Parcel C) has the highest priority for acquisition because it plays an critical role in the long term objectives of the Master Plan. Based on current land prices in the City of $8,000 to $11,000 per acre, the cost for the 15 acres identified in the master plan would range from $120,000 to $165,000. The second parcel (Parcel D) plays an important secondary role in the long term objectives of the Master Plan. It provides an area for support facilities (e.g., parking lot) and neighborhood recreational facilities. Again based on current land prices in the City of $8,000 to $11,000 per acre, the cost for the 7 acres identified in the master plan would range from $56,000 to $77,000. Although these two parcels play an important sole in the park's Master Plan, they may not be either available for purchase or the City may not be 'able to fund their acquisition. If this becomes the case, the overall integrity of the Master Plan is not lost. Even without these parcels, the park will be a priceless natural resource and will make a significant contribution to the park system within the community. However, if the vision of this master planning process is to be realized, every effort should be made to include these parcels within the park. Park Development Costs The cost estimate and general phasing program for developing the park is illustrated in Figure 13 - Cost Estimate and General Phasing Program. The suggested phasing is based on the most reasonable approach to the park's future development. The vegetative management programs are the top priorities. The auxiliary site amenities can be added in the future. The phasing program is based on the best judgements given current conditions. Since conditions and opportunities often change over time, the City and Advisory Committee should review the phasing program on a periodic basis to change priorities if necessary. Interpretive/Education Programs One of the important program elements for this park is the an. interpretive and environmental education program to emphasize the importance of preservation and conservation of limited natural resources. The programs should focus on native plant communities, how they evolve and maintain themselves, and on the wildlife which depend on them for survival. These programs should also emphasize the use of native plants around homes and the benefits they provide, both in an aesthetic and practical sense (such as wind screening, shade, attraction to wildlife, etc.). Environmental education programs for elementary and secondary schools should be a high priority, considering the park's proximity to the nearby schools. The Minnesota Department of Education often assists communities in developing environmental educational programs. State personnel, along with local school district staff, should be contacted and asked to help create these programs. Interpretive programs should be created to reach a wide variety of people and age groups. Interpretive programs typically focus on providing park visitors with information about the plant communities and wildlife within the park. These programs often include: • interpretive nodes (low profile kiosks with interpretive panels). • interpretive signs throughout the park which describes different features. • maps and handouts with text describing the park's ecological systems, wildlife, geology, etc. Development of interpretive programs should also include the Minnesota Department of Education, local school district staff, as well as a naturalist and other environmental professionals. Existing Community Programs This Master Plan does not intend to exclude existing and successful community programs from taking place within park boundaries. However these programs should occur. only if they do not cause significant negative impacts to the park's natural character. Organized events bring visitors to the park and create experiences which give people a vested interest in the future of the park. A pleasant memory of a place can motivate people to protect it as a resource. As an example, there is no compelling reason why the Haunted Woods program should not continue as it has in Carrolls Woods Nature Area 16 City of Rosemount the past as long as its organizers take reasonable care to protect fragile plant life from damage. To accomplish this, organizers of community programs should work closely with the Advisory Committee in selecting a route and location for props. In the future, when the nature area is fully restored and developed, the Haunted Woods program may be better suited to another location. The organizers should work with the Parks and Recreation Committee and city staff in the next few years to see if another more suitable site exists. In the interim, the Haunted Woods program should continue. Advisory Committee The.City should establish an advisory committee to oversee and guide the future development and protection of Carrolls Woods Nature Area. The Committee should be made up of individuals with different backgrounds who can help give direction and motivation to the community in support of the park's Master Plan. The Advisory Committee should work directly with the Parks & Recreation Committee and City staff to guarantee that the park's best interests are served. The Parks and Recreation Committee and City Council should formally accept the Advisory Committee in an advisory role and as the guiding force behind the park's future development in order to add strength to Advisory Committee's position. The Committee's make-up should include: • local citizens who are concerned about the park's future and want to contribute their energies toward insuring that its mission is carried out. • members of local conservation organizations with interest and expertise in native habitat, wildlife observation and wildflower gardening. • members of local garden club(s) who have a special interest in native plants and gardening. • teachers in the local educational community who have an interest in environmental education and interpretation. • community leaders who can provide political guidance and potential sources of private funding. • a City staff member(s) to assist in guiding the project through administrative and political channels. The Advisory Committee's involvement in the development of the park should occur prior to the design development stage of the project. The Advisory Committee should use the Master Plan as a guide to any development within the park. Other key responsibilities for the Committee include: • interpreting the master plan document, including periodic review of the plan itself and the priorities for phasing. • implementing the plan, including scheduling of improvements, securing professional assistance as necessary, and making recommendations to the Parks & Recreation Committee, City staff, and City Council. • initiating education and interpretive programs. • initiating public awareness programs and public meeting to keep the citizens of Rosemount aware of the park's development. • initiating volunteer programs to assist in the development of the park and reduce development costs. • providing on-going guidance and support to volunteer and educational programs to insure the long-term success of the park. • monitoring maintenance practices so that, they stay within the intent of the Master Plan. • monitoring existing community programs (such as the Haunted Woods) and work with program organizers to guarantee that the best interests of the park are served. Conclusion The citizens of Rosemount should commend its City Council, Park and Recreation Committee, and the Advisory Committee for their concern in planning for such a valuable community resource as the Carrolls Woods Nature Area. The Advisory Committee in particular put in many hours debating the issues facing this park and came to some tough and critical decisions about its future. Carrolls Woods Nature Area is a treasure for future generations. Rosemount is lucky to have citizens who feel passionate about its existence and the quality of its environment. Their energy can go a long way toward motivating the community and creating the support necessary to implement the Master Plan. Carrolls Woods Nature Area 17 City of Rosemount kkv.

As you know, I have had an opportunity to reveiw the draft master plan and attended some of the committee meetings and one of the public information meetings. In general, I think the proposed master plan for Carroll's Woods is an excellent document that should provide a solid basis for long- term management and development of the park. I believe that it is consistent with the purposes of the original grant request and the requirements of the grant agreement. On the issue of trails, I believe the plan goes a long way toward resolving some of the concerns I had. For example, the recommendation to eliminate some trail segments, particularly on steeper slopes, is a good one. I feel the committee's original suggestion to provide an entry point on the northwest corner of the park was reasonable, given the inevitable residential development that is bound to occur in that area. The possible compromise, suggested by one member of the committee, to enter the park somewhere between the northwest and southwest corner also seemed reasonable because it still seemed to deal with my concern, and that of several committee members, that there not be a direct trailway through the south end of the park that would be used primarily for access to the school. I would prefer one of these entry points because of this concern. If it is decided that a southwest entry to the park is necessary, S would suggest that the entry be kept unobtrusive by using an easement of no more than twenty feet in width and routing the trail in such a way that it would not be attractive as a transportation route between the neighborhood and the school. I agree with the consultant's conclusion that the two lots in the southwest corner should not be used for parking and that they are not really suitable for development as a neighborhood park. ��, An Equal Opportunity Employer On the issue of vegetative management, it appears that some difficult decisions must be made. After listening to the consultants' explanation of the problem, I personally feel that a long term effort to reduce the Buckthorn and restore other species is the way to go. This may be expensive and require a great deal of effort, but I think the future of the woods as an attractive natural area depends on it. The whole master plan is based on the premise that the area will be managed to preserve its natural characteristics. The proposed additions to the park, while not directly related to the grant requirements, would certainly complement the existing park area, provide additional buffer between the park and future residential development, provide opportunities for restoring some of the original vegetation types and provide for some of the more active recreation uses that are likely to be needed in the future. On the issue of fencing I think the master plan suggests a prudent approach to what could be a controversial and expensive project. While I am not usually a big proponent of fencing parks, in this particular case some good arguements can be made for the possible future need for fencing. At this time, however, it is probably reasonable to direct funding resources toward other high priority items, such as vegetative management and land acquisition, rather than immediately fencing the area. In summary, the proposed master plan for Carroll's Woods appears to be consistent with the requirements of the grant agreement and, if adopted, would establish needed guidelines for the future development and management of the park. While I still have some concern about the development of a southwest entry point, this concern can be eliminated by taking steps to ensure that the trail will not be used in the future as a traffic route between the school and residential area. This concern should not detract, however, from the overall importance and value of the master plan. I think that city officials, your consultants and the citizens who participated in the master planning process have done a fine job in planning for the future of Carroll's Woods. Finally, I want to compliment the City of Rosemount for its decision to undertake such a comprehensive master planning project. It is an effort that, I believe, has already proven its worth and will continue to pay dividends into the future. I also want to thank you for your efforts to keep me informed during the planning process. Sincerely, Wayne GSames, Director Outdoor Recreation Grants Program Master Plan for Carrolls Woods Nature Area V Planning Overview In early 1991 the City of Rosemount undertook this master planning study for Carrolls Woods Nature Area to define its long-term purpose and objectives for development. To accomplish this task, the City: • appointed an ad hoc advisory committee of local citizens to oversee the development of a master plan for the park. • hired the firm of Brauer & Associates, Ltd. to facilitate discussion and develop a park master plan document. The master plan document consists of the following major components: • Development Program: defines the park's general purpose and identifies the major issues affecting its future development. • Alternative Concepts: illustrate a number of schematic designs and physical relationships in response to the development program. • Site Inventory: identifies the site's existing physical characteristics such as soils, slopes, drainage patterns, etc. • Site Analysis: makes judgements about the site and identifies the site's opportunities and constraints for development. • Site Master Plan: is an outgrowth of the accepted concept plan and represents the design solution that best responds to the development program and site inventory/analysis information. • Vegetation Management Program: identifies the key Carrolls Woods Nature Area management objectives to assure long term ecological diversity and integrity. • Wildlife Habitat Program: identifies the key management objectives to assure that the needs of wildlife are met. • Cost Estimate and General Phasing Program: projects the anticipated costs to develop the park and establishes a general phasing program. • Education and Interpretive Program: identifies key objectives of education and interpretive programs. • Advisory Committee: defines the critical role the advisory committee will play in overseeing the development of the park. The findings related to each of these components are summarized in the forthcoming text. Development Program The Advisory Committee defined during focus meetings the heritage and general purpose of Carrolls Woods Nature Area and identified the major issues affecting its future development. These items make up the development program. The development program is important because it provides the direction and basis for the entire master planning process. LAWCON Grant Carroll's Woods Park was acquired by the City of Rosemount in 1975 through the State of Minnesota's Outdoor Recreation Grant Program (LAWCON). City of Rosemount According to the original grant application, the intent of the project was to "protect (from development) a natural, wooded area within a growing part of the metropolitan area" and to "provide some outdoor recreational and outdoor educational opportunities for the citizens of Rosemount." In subsequent years the City applied for a number of revisions and amendments to the original grant. I AWCON, in most cases, granted these requests. Since the original grant was obtained in 1975, the City has created some trails and removed many dead American Elms from the property. There has been no other substantial development. Wayne Sames, Director of the Outdoor Recreation Grant Program (Community Development Division of the Minnesota Department of Trade and Economic Development) represented the State in interpreting the provisions of the various grant application. Under his interpretation, the current level of development was considered to be within the guidelines and general parameters established as part of the original grant application and subsequent amendments. With respect to future development, Mr. Sames indicated that, under the State's interpretation, the park should: a) continue to focus on the preservation of the resource and b) provide passive recreational opportunities, such as nature observation, educational programs, walking trails, benches, etc. for the citizens to enjoy. General Purpose(s) Of The Park Given their understanding of the park's history and what it means to the community, the Advisory Committee was asked to identify what they considered to be the general purpose(s) of the park: Conservation and Preservation: to protect the site and natural environment from encroaching development. Passive Recreation to provide opportunities for passive recreational activities such as: • walking/hiking (accessible for the handicapped) • nature/wildlife study • family and individual "quiet space" • informal cross-country skiing/snow-shoeing (groomed for one track of skiing only) Interpretation and Education: to provide opportunities for education and interpretation without jeopardizing the park's natural character. The City and School District should develop programs for a variety of potential users groups, including: • school children of all age groups. • individuals and families. • seniors and special populations. Carrolls Woods Nature Area should allow "passive" education so that an individual can gain knowledge in an informal manner. This passive education would include such things as interpretive signs, printed site maps as well as informational brochures, etc. General Issues Related To The Parks's Future Development Along with identifying the purpose(s) of the park, the Advisory Committee also identified a number of needs to address during the planning process. These included: • a general inventory/identification of existing plant communities and vegetation. • a need for a vegetation management program. • a need to provide wilMe habitat. • a need for an interpretation program to identify and describe the various plant communities and wildlife. • a need to encourage the local school district and local civic groups to participate in the development of a comprehensive educational program to educate people (of all ages) about plant communities and wildlife. • the need to maintain some form of site access and- control. ndcontrol. Potential uses of Carrolls Woods Nature Area which could damage it included: overuse of the park, free -roaming domestic animals attacking wildlife, motorized vehicles entering the park, and other "nuisance" problems, such as kids starting campfires, smoking, drinking, littering, etc. Uncontrolled access also allows a convenient "thoroughfare" from the west side of the park to the high school area. • the need to define more clearly the purpose of the internal traiil& The 'Committee expressed concerns about the need to reduce the width of the trails, the desire for woodchip trails, and limiting the grooming of cross-country skiing trails. the need 'for additional parking. The Committee considered the parking lots for Schwarz Pond Park and Carrolls Woods Nature Area City of Rosemount 2 Rosemount High School to be too far away and often unavailable to potential users of Carrolls Woods Nature Area. • the need for additional site amenities such as benches, signs, observation blinds, bridges, etc. • the need to identify and capitalize on the opportunities inherent in Carrolls Woods' proximity to Schwarz Pond and Rosemount High School • the need for neighborhood recreational facilities to service the recreational needs of the neighborhoods to the west and north of the park. Note: this was identified within the overall park system plan for the City. • the possibility of including a prairie preserve area within the park. • the need to address safety issues (personal and physical). Addressing these needs provides the direction and basis for the entire master planning process. Alternative Concepts Three alternative concepts explored different boundaries for Carrolls Woods Nature Area and illustrated different management techniques and relationships between physical uses of the site. These concepts respond to the issues listed above in the Development Program. Fgwes 1, 2, & 3 illustrate three alternative concepts for the park. After considerable debate, the Advisory Committee selected Concept #3 (Figure 3) because it: responded to the criteria as set forth in the development program. provided a visionary approach to the park's future development. • allowed for more diversity in plant communities and wildlife species than the other concepts. Based on these findings, Concept #3, along with the development program, provided the basis for the continued progress in the master planning process. Brauer & Associates Ltd. used this concept to begin an inventory of the study area, analyzing its opportunities and constraints in light of the development program and finally to refine the concept into a Site Master Plan. Site Inventory Site inventory identifies the existing characteristics of the proposed park area (including geology, topography, drainage, soils, and vegetation). Based on Concept Plan #3, the study area breaks down into four adjacent parcels of land. Rosemount currently owns two and would have to acquire the other two parcels through parkland dedication, direct purchase, and/or grant money. Figure 8 - Site Analysis identifies four parcels within the study area: • Parcel A: includes Carrolls Woods Nature Area as defined by its current (1991) boundary (45 acres). Acquired by the City through a LAWCON grant in 1976 for passive use, nature preservation and environmental education. • Parcel B: includes the part of Schwarz Pond Park which lies west of the north -south asphalt trail (e.g., west of the existing ballfield). This would include the pond itself (31 acres). The parcel is already owned by the City. • Parcel C. is an area which lies between Carrolls Woods and an existing gasline easement north of the park. This parcel is currently used for pasture land and is not owned by the City (15 acres). • Parcel D: is an area west of Schwarz Pond, north of Parcel C, east of a dominant ridge line, and south of a future collector street. This parcel is also currently used for pasture land and is not owned by the City (7 acres). Geology, Topography, and Drainage Thousands of years ago the climate of Minnesota warmed and the glacial ice which covered Rosemount began to melt. As the glaciers receded northwards, they deposited huge amounts of debris which had been carried in the ice. The deposits of sand and gravel and boulders, often over one hundred feet thick, are known as terminal moraine. The topography of the terminal moraine is rolling with steep hills, ridges, and landlocked depressions. Some level areas do exist at the base of slopes, in saddles and depressions, and on hilltops. The slopes of Carrolls Woods are mostly hot, south- southwest facing slopes. The Schwarz Pond parcel is a hot Carrolls Woods Nature Area City of Rosemount west -facing hillside. Parcel D has mostly north -facing slopes and the most moderate topography. Parcel C is a series of ridges running north to south with steepest slopes facing east and west. Glaciers determined the landscape of Carrolls Woods and set up the drainage patterns which still exist today. Figure 4 - Dmimagie Paltems illustrates the site's current drainage patterns. These patterns are critical to the formation of soils and the subsequent development of plant communities. In Figure 4 - Dndnage Pauems, the thick dashed lines mark the high points of the property and the boundaries of the watersheds. Water flows in opposite directions on either side of these lines. It is interesting to note the north -south pattern of ridges within the study area which mark the direction of receding glaciers. Because of the steep slopes of these ridges, the watersheds would tend to drain rapidly after a heavy rain. Since the watersheds are small, their lowpoints would not collect much runoff. Even so, one would expect to find wetlands in the several landlocked depressions on the property unless the soils are porous. Soils After the glaciers melted, weathering forces began to act upon the rock and debris left behind and started to form soils. Soils and slopes are intrinsically related. Slopes affect the degree of wind and water erosion, the rate at which moisture is absorbed and retained, and finally in the amount of sunlight reaching the ground. These factors in tum affect the growth of vegetation and the subsequent development of soil strata called a profile. Any management program should begin with an examination of the area's soil profiles. Soils offer an explanation for existing plant communities and affect the success of any planting restoration efforts. Figure 5 - Slopes and Soils shows that the study area is generally a dry site. No clay soils are present. Most of the soils are sandy or silt loams with moderate to steep slopes. This means water either runs off rapidly or percolates through rapidly. The subsoils are usually composed of several feet of sand and/or gravel. Depressions on the site are silty loams and poorly drained; these soil types make up a very small percentage of the total acres of the study area. Figure 6 - Soil ChanutoWd explains the possible uses of each soil type found within the study area. The Dakota County Soil Survey states that the hillsides of the study area are generally most suited to woodland or prairie/ pasture/hay. Tilling is often difficult. The Soil Conservation Service recommends using drought resistant species on the most of the hillside soils. Carrolls Woods Nature Area Vegetation 150 years or so ago the Rosemount area was predominantly oak savannah and prairie. Prairies are communities dominated by grasses and forbes. Oak savannahs consist of isolated oaks or small stands of oaks surrounded by a sea of grasses and wildflowers. Both plant communities are dependent on fire for continued existence. The savannahs, with their open vistas and groves of beautifully -formed craggy oaks, were particularly attractive to European settlers who were reminded of the parklands of their home countries. As the settlers turned the savannahs into home sites and farms, they also suppressed the fires which are so critical to the continued existence of the prairie and oak savannah communities. In the absence of fire, woodland species invaded uncultivated savannahs and prairies. In the full sunlight between the established Bur Oaks of the savannahs, Black Cherry, White Oak and Red Oak sprouted and grew. Sun -loving shrubs such as Hazelnut, Sumac, Gooseberry and Raspberry also invaded. When wildfire was suppressed, American Elm, Boxelder, Hackberry, Green Ash began to take hold. Under their canopy, the more shade -tolerant shrub species such as Elderberry, Dogwoods and perhaps Arrowwood and Nannyberry Viburnums grew. Within 50 years of the arrival of settlers, the savannahs and prairies of Rosemount had changed dramatically. In addition to suppressing fire, the European settlers also brought with them plant diseases and non-native shrubs and trees which sometimes out -competed native species. 25 years ago, American Elm probably.dominated the tree canopy of Carrolls Woods. Since then almost all the American. Elm has died of Dutch Elm disease and has left the central portion of the 45 acre parcel with a very sparse canopy of trees. Common Buckthorn (Rhamnus cathartica), a particularly aggressive non-native shrub, has invaded the property and has virtually taken over the understory. Tartarian Honeysuckle and woody vines have also been aggressive invaders. Fortunately in the last decade the Tartarian Honeysuckle has died out because of aphid attacks and concerned citizens of Rosemount cut and reduced considerably the vines strangling many canopy trees. Today the canopy of trees in Carrolls Woods is composed of the following species: Boxelder (Acer negundo) Green Ash (Fraxinus pennsylvanica) Black Cherry (Prunus serotina) Hackberry (Celtis occidentalis) Red Oak (Quercus rubra) Northern Pin Oak (Quercus ellipsoidalis) Bur Oak (Quercus macrocarpa) City of Rosemount White Oak (Quercus alba) Silver Maple (Acer saccharinum) Cottonwood (Populus deltoides) Aspen (Populus sp.) Boxelder and Green Ash are the most common trees of the uplands. Black Cherry and oaks are also quite prevalent with some beautiful stands of mature individuals scattered throughout the site. Several Silver Maple dominate the moist lowlands of the site. One enormous Cottonwood grows along the trail which runs across the southern edge of the property. Small mature stands of aspen are scattered throughout the uplands. Aspen are short-lived in a forest because they are intolerant of shade. They may seed in or root sucker into openings, but as the canopy closes in, they will begin to die out. Ecologists and foresters examine the understory of a forest to determine the future of its canopy. The understory of Carrolls Woods and the forest west of Schwarz Pond has a rather depressing story to tell. Barring human intervention or natural catastrophe (fire), Carrolls Woods will succeed to an almost pure stand of impenetrable Buckthorn with some Boxelder as the existing canopy trees die out. There are almost no seedlings of oak or cherry present in the 45 acres except in small openings with full sun and no Buckthorn. Occasional saplings of Green Ash and Hackberry are present but even they are rare. Shrub species other than Buckthorn are also uncommon- Occasional ncommonOccasional Elderberry and Prickly Ash are scattered throughout the site. The ground layer of Parcel A (Carrous Woods) shows quite a diversity. Although not closely inventoried, Jack - in -the -Pulpit, Trillium, ferns and mosses are present in various areas of the site. These species indicate moist or mesic microclimate conditions and need shade to survive. Nettles, gooseberry, raspberry and seedlings of the ever- present Buckthorn are common along paths and in openings where there is full sunlight. Parcel B (part of Schwarz Pond Park ) consists of a hot west -facing slope which leads down to the pond. The slope is covered by a well-established canopy of Northern Pin Oak, Red Oak, White Oak and Black Cherry with a dense understory of Buckthorn. The eastern and northern shores of the pond are primarily open with young successional woodlands of pioneering species (aspen, Boxelder, and willow) and stands of sumac. Parcel C is a open, rolling site with one very small remnant of prairie. The topography is spectacular and interesting. It is currently used as sheep pasture. Parcel D is a open, rolling site with some fairly level topography. It too is used for sheep pasture. General Perceptions of Vegetation It is clear that Rosemount citizens are very fond and protective of Carrolls Woods and the Schwarz Pond property. Most people enjoy strolling under a lush, cool canopy of trees in the summer. They appreciate the beauty of the woods as they are now and are more interested in sensory experiences rather than how "pure" the ecological communities are. Ecologists, on the other hand, see Carrolls Woods through different eyes: as a forest of mixed hardwoods considerably degraded by Buckthorn and with a limited future. The short-term management objectives for the two views of the woods are opposite; the first demands little disturbance of existing conditions, the second demands heavy intervention and manipulation to maintain ecological diversity. Left on its current course, the canopy of mixed hardwoods will continue to die out and be replaced by Buckthorn which effectively shades out any tree seedling or sapling. In the not -to -distant future, Carrolls Woods will evolve into a dramatically different place: a sea of Buckthorn. The trails will become corridors through a dense mass of 20- 25 foot Buckthorn with no cool shade and no sensory diversity. At this point in time the two opposite approaches for forest management will become similar, demanding intense intervention to recreate the canopy. The perceptions of the public, rather than the ecologists, are critical to the acceptance of the Master Plan for Carrolls Woods Nature Area. Brauer & Associates Ltd. recognized this and inventoried the vegetation of the four parcels in a manner which would address these perceptions. The wooded areas of the study site were divided into six forest types (see Figure 7• Vegetation). Each type has a different type of canopy and understory and very different visual and sensory qualities. Site Analysis Site analysis uses inventory information to make judgements about the site. Site analysis identifies opportunities and constraints for development. Access and ControL• Users of Carrolls Woods currently enter the 45 acre parcel from several points. The asphalt trail running "along the eastern border is the most sanctioned entry point. Several trails of varying widths enter the woods off this trail. Another main entry point is Carrolls Woods Nature Area City of Rosemount 19 at the bottom of a steep hill in the southeast comer of the property. There are three points of entry along the west border. The Advisory Committee felt strongly that the number of access points into Carrolls Woods Nature Area be limited. The Committee also felt that entry points will be needed on the north, west, and east side of the property. Internal Trail System: Many trails crisscross Carrolls Woods. They vary in width, degree of steepness, and quality of the surface. The Committee did not want to create new trails unless necessary and felt some trails should be eliminated or realigned. Currently teens often use a trail along the southern edge of the woods as a way to get to and from Rosemount High School. As residential development on the west side of the park continues, use of this trail will likely increase. The Committee felt that they did not want Carrolls Woods Nature Area to be used merely as a shortcut from one point to another. Figure 8. Site Analysis highlights those trails which should be eliminated because they are redundant, too steep, too wet, or because they serve undesirable access points. Site Amenities: There are no benches, signs, or other site amenities in Carrolls Woods. There are many opportunities for these built facilities which should be added once restoration efforts for the plant communities are underway. Parking: Visitors coming to Carrolls Woods by car must use the parking lots for Rosemount High School or Schwarz Pond Park. These are so far away from the woods that it takes a good walk just to get to the park. Also the lots are often full. Topography and existing development around the perimeter of the site presents a challenge to the designer of a parking lot which requires level grades. Parcel D has the most level grades for parking. The two lots owned by the City in the southwest comer are inadequate in size to serve the future parking needs of the park. Neighborhood Recreational Facilities: Parcel D is an open, rolling area with some fairly level topography. It will be immediately adjacent to a proposed collector street. In the near future the areas north and west of this parcel will likely be developed for residential housing. These communities will need neighborhood recreational facilities within walking and biking distance. Parcel D has the acreage and enough level topography for these recreational facilities. Schwarz Pond: The pond within Schwarz Pond Park is a significant natural area and has value as wildlife habitat. It has limited value as a recreational lake. The woodland east of the pond has many lovely oaks and cherry trees. This area should be included in the Carrolls Woods Nature Area. Parcel C: With its dramatic topography and open vistas and its existing use as a pasture, this area is perfect for prairie and oak savannah restoration. Near the northern border of Carrolls Woods is a mature, beautifully -formed Bur Oak and a nice stand of smaller Bur Oaks. The form of these trees indicates the area could have once been a savannah. Woodland Vegetation: the inventory of vegetation in the study area indicated six types of forest. Each type will have a different management approach (defined in the Vegetation Management Program). Control of Buckthorn will be critical in all areas. Fguue & SiteAnalp* simplifies the areas of forest for the purpose of management. • Degraded Woods: sparse canopy; isolated mature trees @ 150-200+ feet apart. Understory is a impenetrable wall of Buckthorn. • Open Canopy: mature trees are much more common and closer together. The understory is still fairly dense Buckthorn. • Pleasant Woods: mature trees form a good canopy with some Buckthorn in the understory. • Lowland forest: these small areas are disturbed frequently by groundwater or wet soil conditions. Gigantic Silver Maples and Cottonwoods are common with an ground layer of nettles. ., • Successional: young trees, dense understory with a variety of species. Master Plan The Master Plan is a direct outgrowth of the accepted Concept Plan and represents the design solution that best responds to the development program and the site inventory and analysis. Fgune 9. MasterPlan illustrates the results of the planning process for Carrolls Woods Nature Area. This graphic: • clearly defines the park's property boundary (consistent with Concept Plan #3) to ensure diversity of plant communities and wildlife habitat. locates and sizes all appropriate facilities and site amenities. Carrolls Woods Nature Area City of Rosemount • establishes appropriate plant communities which are the basis for wildlife habitat. The following tem describes each physical element of the Master Plan and explains the reasoning behind the design. It is clear that Rosemount citizens feel the need for an undeveloped area where they can stroll and appreciate the beauty of nature. A number of recent studies have documented this need, which is likely to become more acute as the community continues to grow. Likewise, Rosemount schools will continue to need a place for environmental education and interpretation. It is important to recognize that Carrolls Woods Nature Area is different from other community -type parks: its environment is more fragile and complex. Human activity and intervention can easily change the character and overall quality of this natural area. To insure the long-term preservation of Carrolls Woods Nature Area, it will be critical to protect the park from the pressures associated with suburban development. These pressures raise the issue of control and access. Currently Carrolls Woods has an unfenced perimeter. Although it is not easy for the average citizen to reach the park (parking is far away), it is easy to enter the woods at any number of locations. There is no perceived stewardship of the park. This lack of control works fairly well with the existing level of use of the park and with the land uses which currently surround the property, i.e. farmland to the west and north, the high school to the east, and homes to the south. Without a doubt, this casual approach to control is ideal and very appropriate in the near future while the community begins managing the plant communities of Carrolls Woods Nature Area and developmental pressures around the park remain limited. However times are changing in Rosemount. Within the nem decade residential development will occur to the north and west of the park. As undeveloped land disappears from the community, citizens will have a greater desire to spend time in a nature preserve. The City will want to make access to the park as a community resource easier for the average citizen by providing parking and trails. Undesirable activities within the park will increase as the population of Rosemount grows. Free -roaming cats and dogs will disturb wildlife. Small footpaths begin to increase in width as people make their own shortcuts. Students will cut through the park to get to the high school. Unauthorized uses (parties, campfires) and nuisance and vandalism problems tend to increase in areas that the public does not perceive as controlled. All these pressures will degrade the woods as a natural area. At some point in the future Carrolls Woods Nature Area will likely have to be protected by some means other than the goodwill of Rosemount citizens, namely a fence around the perimeter. This circumstance is certainly not unique to this park. Virtually all nature centers with limited acreage in the Twin Cities metropolitan area fence their property. The fence becomes not only a physical barrier but a psychological one as well. It makes a statement to the community that the area is special and needs protection. By limiting the number of gates, the City can control the hours and season of use (if desired) and most undesirable activities. Gates are also opportune places to present rules and interpretive information. Fences discourage unauthorized uses, encroachment, and trespassing on private property., Specifically, the fence is intended to: • clearly define the parks perimeter and make a statement as to its intended purpose. • protect the park from developmental encroachment. • restrict site access to pedestrians and maintenance vehicles and thereby limit trails. • control free -roaming domestic animals. • prevent motorized vehicles and bicycles from entering the park. • control "nuisance" problems, such as kids starting campfires, smoking, drinking, littering, etc. • prevent the park from becoming a convenient "thoroughfare" between the developing part of the City to the west and north of the park and the schools and major community center. After considerable discussion and debate, the Advisory Committee recognized that the need for a fence may become a reality at some point in the park's future and that a fence should be included in the Master Plan. However, the Committee also felt that there is no compelling reason at this point to have the fence high on the priority list for development. Instead, the Advisory Committee should review on a periodic basis the need for a fence, along with other development considerations. The Committee should use as criteria the items listed above to determine whether or not the fence is needed. If the site begins to degrade from unauthorized uses and these uses cannot be effectively controlled by other means, the City will have to consider strongly installing the fence to protect the site. Initial reactions to the idea of a fence around the Carrolls Woods Nature Area may be that it is intimidating, unnecessary, and ugly. However, this does not have to be Carrolls Woods Nature Area City of Rosemount the case. If installed properly, a fence can be relatively unnoticeable. Vegetation will screen it. Psychologically, the fence becomes a barrier to the human world that, in the not so distant future, will encircle the park. Those who are involved in the park's future development should go out to any one of a number of fenced nature areas within the metropolitan area and see for themselves how little a fence affects the park's atmosphere. Should a fence become necessary in the future, it should be six foot in height. Galvanized chainlink fence of a suitable commercial grade is the most commonly used material because it is relatively economical to construct and reasonably durable. As the Master Plan illustrates, the fence is intended to essentially follow the park's property boundary. To limit its visual impact and make it as unobtrusive as possible, the fence should be set back 15 to 20 feet from the property line and be screened by surrounding vegetation. This is particularly true in the more heavily wooded areas of the site, where the fence's alignment will be dictated as much by the existing vegetation as by the property boundary. Care should be taken during the fence's installation to disturb the existing vegetation as little as possible. Installing the fence in the late fall when plant life is largely dormant and avoiding existing trees will minimise damage to the park. In open areas planting vines and shrubbery will help screen the fence from view. In areas where the fence will be adjacent to existing residential properties, the City should make homeowners aware of the fence's proposed alignment prior to its installation. Some homeowners may prefer the fence along the property line rather than set back and screened from view. The Master Plan identifies three pedestrian gates to provide access into the park. The tum -style type, pedestrian -only gate in the southeast comer of the site will serve the already -developed residential "core" of the City as well as the school. This entrance should be very simple and unobtrusive, with an asphalt trail providing access from the existing roadway down to the gate. The access shown on the northwest comer of the site will serve future residential areas to the west and northwest of the site. This gate should also be a tum -style, pedestrian - only gate. To access the gate from the residential street west of the park, the City needs to acquire a 25-30' wide easement to allow for grading, screening and building a trail. The main entrance gate on the north side of the site will serve not only those walking to the site but school buses and those driving to the site from other areas of the community. This entrance should be simple and natural in design and make a statement that the visitor is entering the nature area and a protected environment. This gate should be limited to pedestrians. A gathering area outside the gate should accommodate a group of 25 people (a class of students). This area will include benches and perhaps a kiosk. Inside the gate, a kiosk provides visitors with a map of the area and a brief description of what might be seen. The displays should include photos, graphics, and written text to describe and illustrate the park's features. The kiosk should have a leaflet box to dispense park maps/guides. The Master Plan includes a number of gates for maintenance vehicles. The primary access is near the main entrance gate on the north side of the park. This access should serve most maintenance needs once the park is fully developed. A second access is shown near the pedestrian entrance on the northwest. A third access is shown near the existing hockey rink on the southeast side of the site. This access will probably serve as the primary maintenance access until the park becomes more fully developed. This gate can be opened in October for participants in the Haunted Woods program. The Advisory Committee debated at length the issue of whether or not to provide a pedestrian access in the southwest comer of the site. After lengthy discussions, the majority of Committee felt that a gate, in the northwest would better serve the park because: • it was more centrally located to serve the residential areas to the west as well as the northwest. • it reduced the likelihood of the park being used as a "thoroughfare" from the western part of the community to the high school and other community areas east of the park. I _ . Since no pedestrian access is planned for the southwest comer of the site, the park dedication land currently owned by the City adjacent to the park is of little future value (for the purpose of accessing the park) and could be, at the discretion of the City Council, sold -off for residential development. The Advisory Committee also discussed the twenty foot easement near the southeast comer of the site. Given its relatively steep grades and the current lack of use as an access to the park, the Advisory Committee felt no action was necessary at this time. However, the members of the Committee did agree that the issue should be reviewed again prior to installing the fence, should the fence become a reality in the future. Internal Trail System An internal trail system which meanders through the park will move people through the nature area with a minimum Carrolls Woods Nature Area City of Rosemount a impact to the environment and yet insure that they receive a quality outdoor experience. Although the primary objective of the trails is to link together the various plant communities, the system should also be developed to take advantage of the varying topography, views, and vistas. The trails should provide visitors with a variety of perspectives and experiences. Figure Ia- Typical Trad Dass -Section for Canvas Woods Nature Area shows the suggested design for internal trails. In order to keep the experience of the woods as intimate as possible, the width of the trail should be six feet with a one foot maintenance strip on each side. The surfacing material should be: compacted crushed aggregate (suitable for handicap accessibility) on the primary loop within the wooded and prairie/savanna areas. • woodchips on the auxiliary and secondary trails within the wooded areas. mowed grass on the auxiliary and secondary trails within the prairie/savanna areas. Because one of the primary development objectives is to limit disruption to the existing mature vegetation, the Master Plan uses existing trails within the park as much as possible. However, some changes will be needed where existing trails do not serve a future purpose and/or where their grades are excessive. In some cases, trails will be eliminated because they serve undesirable access points. Since the existing trials vary from four to twelve feet in width, they will require some reworking, much of which can begin immediately. Also, even though the trails shown on the Master Plan may follow existing alignments, they may need redesigning to make sure that they are safe and maintainable. The new trails shown on the master plan supplement the existing trails. All of the trail alignments, both old and new, should give the user a quality experience of the park with many options for routes to walk. The exact location of each trail must be established in the field during design development (i.e. the "next step" in the planning process) to take advantage of the opportunities afforded by the site. In other words, the trail alignments as illustrated on the Master Plan should be considered approximate and not absolute. As with the existing trails, new trials should be designed to make sure that they are safe and maintainable. Carrolls Woods Nature Area should be a community resource in the winter as well as in the spring, summer and fall. Snow and ice can be barriers to using the trails. The Advisory Committee felt that a single groomed track for cross-country skiing would allow people to experience the Carrolls Woods Nature Area woods in winter and would not detract from the quality of the environment. A single pass through the woods by a snowmobile trailing a pair of weighted skis would create a narrow trail for skierswhich would not damage surrounding vegetation. Site Amenities Enhancing the perceptions and experiences of park visitors through the careful use and placement of site amenities is important and will greatly affect the overall success of the park as a public resource. Site amenities are the built features which increase the comfort/access of the park users. As with the trial alignments, the exact locations of the various site amenities must be established in the field during design development to take advantage of the opportunities afforded by the site. All of the site amenities should be natural and simple in design and as much as possible blend into the environment that surrounds them. Interpretive Nodes and Signs: interpretive nodes are places along the trail with low profile kiosks. These kiosks have interpretive panels and exhibits which are fun and easy to read with good graphics and minimal text. Interpretive nodes are typically located near benches and other site amenities (i.e. decks, docks, etc.). Located along the trails, unobtrusive interpretive signs will identify the various plant communities and wildlife species and augment the interpretive nodes. Benches: should be provided to take advantage of different views and site features, ranging from quiet, intimate spots to wide open vistas. Again, benches can be installed at interpretive nodes if appropriate. A Floating Boardwalk: located in the wet prairie area gives park users an close -hand experience of the tall grasses and forbes of the wet prairie. Environmental Education Dodc provides an educational opportunity for schoolchildren so that they can study pond life and take water samples, etc. In addition, the shop students from the local schools could help construct the dock as part of their classes. Pond Overlook Doc]- provides park users with a pleasant place to sit and view the pond. Two benches allow seating. Pond Observation Blind: provides park users with an opportunity to view waterfowl activities. If properly designed, the blind hides people whose presence and movements normally scare the waterfowl away. The blind is on the edge of the pond and surrounded by vegetation to help screen it from view. An elevated catwalk from high ground provides an interesting access to the blind. City of Rosemount Wooden Bridge Across Woodland Pothole: is a simple structure with a railing that crosses the woodland pothole at a narrow point. "Lookout' Tower. gives park users a birds eye view of the area and is another opportunity for a visitor to observe nature in relative anonymity. A height of thirty feet should elevate the tower platform above most of the understory trees. Woodland Dedc is another simple structure with benches designed for resting and observing nature. Cottage House for Interpretive Displays, Storage, Meetings, Etc.: is a simple building to serve the listed uses. The building should be sited near the main entrance gate at the edge of the savannah. It should have a low profile and use natural materials to blend into the surroundings. A patio outside the building allows visitors a place to sit and observe the prairie. Entrance Drive and Parking Since the entrance drive is the first contact that visitors have with the park, it should be located in a manner which compliments the existing topography. The entrance drive will tie into a future collector street which is likely to be developed north of Schwarz Pond Park. The parking lot at the end of the entrance road should be sized to prevent overuse of the park but large enough to allow a bus to turn around. Ideally, the lot should be paved with asphalt to minimize long-term maintenance and dust. Since the entrance drive and lot are outside the nature area itself, they will technically be part of Schwarz Pond Park. Users of the picnic areas on the west end of the park will probably park in the lot. A lot for35 to 50 spaces plus several bus parking stalls will probably be sufficient to satisfy the parking needs of the users of both the nature area and Schwarz Pond Park. However, as actual design and construction of the lot and entrance road become reality, the City should closely examine potential demand for parking and size the lot accordingly. Neighborhood Recreational Facilities The city-wide park system study identified the need for neighborhood recreational facilities for this area of the community. Parcel D is an open, rolling area with some fairly level topography and is adjacent to the proposed collector street. Parcel D is the best site within the study area for neighborhood recreational facilities. Carrolls Woods Nature Area /^ Since it is the policy of the City to include input from area residents when determining what recreational features will be in the park, the facilities shown on the plan are for reference only and need to be confirmed (or changed) when development actually occurs. These recreational facilities should be connected by trails to the community -wide trail system. Schwarz Pond Park The pond within Schwarz Pond Park is a significant natural area which could add greatly to the diversity of plant and wildlife habitat within the park. The area east of the pond can provide excellent waterfowl nesting habitat if current mowing practices are discontinued and the City restored the area to prairie. Fencing (should it become necessary) and wildlife plantings along the asphalt trail would keep domestic animals from disturbing nesting areas. The wooded area, as a beautiful natural area west of the pond, should be included and managed as part of the park. Its location next to the pond enhances the wildlife value of both areas. The pond is a ecological community which has important education and interpretive possibilities. The City or Science Department of the Rosemount High School should monitor the water quality of the pond to protect its integrity as a resource. The Master Plan shows a number of amenities within Schwarz Pond Park and outside the nature area. These amenities include two scenic overlooks and a number of picnic areas near the parking lot. The overlooks should be mowed areas or decks with benches overlooking the pond. The picnic areas should also be simple in design, with a number of picnic table and grills and perhaps a small - group picnic shelter. External Trails External trails provide access to park entrances and play an important role in how well the park ultimately serves the residents of Rosemount. The three entrance gates should tie into the community -wide trail system which is defined within the City's Comprehensive Park Plan and Development Guide. The existing asphalt trails on the east side of Carrolls Woods and Schwarz Pond will ultimately be outside the (fenced) nature area. The trail to the southwest entrance can easily tie into the City of Rosemount already established community trail along the 142nd Street West. The trail to the northwest gate and main entrance gate are important. Since no access is planned for the southwest corner of the park, the residential areas to the west need a safe means to get to the northwest entrance. Likewise, the communitytrail built along the future collector street north of the park will be an important link to the communities to the north and northwest of the site. The Advisory Committee and City should review access concerns periodically and in conjunction with planned development in the area to insure that trail access opportunities are not lost along the way. Vegetation Management Program The Vegetation Management Program identifies the management approaches and procedures to guarantee the ecological diversity of the Carrolls Woods Nature Area so that it will be a treasure and resource for future generations. In order to maintain long-term ecological diversity and integrity, the wooded portions of the park must be managed and improved and the open areas need to be restored to prairie or savannah. Vegetation management programs can be geared to create five different types of sensory experiences of Carrolls Woods Nature Area and adjacent parcels. These sensory experiences also represent different ecological communities. Dense canopy: 75%-95% overstory coverage with sparse understory (relatively open). Sensory experience: lush, shady, cool. Open feeling under a ceiling of trees. Long views through woods. This type of feeling is most common in a lowland forest or in a mature Sugar Maple -Basswood forest. The latter requires moist (not wet), protected and semi -shaded conditions. Neither Sugar Maple or Basswood grows naturally on the site; introducing these species would create an anomaly or artificial condition. It might be beneficial to attempt to create this woodland community for an environmental education program. Moderate canopy. 40%-60% overstory coverage with moderately ,dense understory. Cool shade dappled by sunlight, limited views. Common in a mixed hardwood forest. This sensory experience is probably most popular among Rosemount citizens and already exists along most of the trails and along the northern edge of Carrolls Woods. Sparse canopy: less than 15% overstory coverage and dense understory. Without fire, this community is dominated by aggressive pioneering plants. The sensory experience in summer is hot, walled -in, transitional, young, not as appealing as types listed above. This condition is frequent in the center portion of the site with dense Buckthorn. Savannah: mostly open with occasional spreading individual trees or small stands of stunted trees. Intense sunlight with pockets of shade. Bright, hot, open, windy in summer. In winter, savannahs feel exposed and cold; snow melts away quickly especially on south -facing slopes. Attention focuses on landform and trees. Oak savannahs are rare plant communities today. Prairie: open, hot often uncomfortable in the summer unless there is a good breeze. Pleasant in spring and fall. Windy and unprotected in winter; snow disappears quickly on south -facing slopes. Attention focuses on landform, the texture and color of grasses, the washes of color from wildflowers. Prairies can grow in a variety of situations: from wet, poorly drained areas to dry, barren hilltops. Available water and the depth of topsoils determine which species of grasses and wildflowers will best grow. Existing Site Opportunities. The two wooded parcels within the study area (Parcels A & B) currently provide opportunities for nature lovers. to enjoy two types of Minnesota forests: the dry upland forests of mixed hardwoods (oak, cherry, ash, Hackberry) and lowland forest of boxelder, cottonwood and silver maple. Parcel A (Carrolls Woods) has one north -facing slope which could provide the cooler microclimate conditions needed for a moist upland forest (Sugar Maple -Basswood). Parcel C is an open, rolling site with one very small remnant of prairie. The topography of this parcel is spectacular and interesting and has great potential for prairie and oak savannah restoration. If possible, Rosemount should acquire enough land to control the viewshed (i.e. to the tops of ridge lines) and should also consider scenic easements. Aesthetics suggest softening the straight line boundaries between woods and pasture (prairie) that exist along the northern boundary of Parcel A (Carrolls Woods) and along the eastern border of Parcel B (Schwarz Pond Park ). For this reason, some of the oak woods along the western edge of Parcel B be restored to savannah. Since savannah is more easily restored than recreated, Rosemount should treasure the savannah type oaks (Le. 100-150 year old Bur Oaks with rounded canopies) which exist within the study area. Management Objectives. The management objective of woodland management within the nature area is to maintain diversity within the existing woodland communities. This will insure that the future generations Carrolls Woods Nature Area City of Rosemount will be able to enjoy a forest of trees rather than a monoculture of Buckthorn. Woodland management will be a tricky issue for the City. The Buckthorn infestation is so severe that removing it will devastate the forest for a few years until other species take hold. Unfortunately, there is no alternative if Rosemount citizens want to achieve the long-term goal for the park with ecological diversity. Phasing and public awareness/education will be critical to public's understanding of what is happening within the park and to their support of management efforts. The restoration of prairie and oak savannah should not create the same concerns as the woodland management program. The proposed sites for these communities are currently in pasture and restoration efforts will not appear to change the area so dramatically. Burning may present some problems, but again publicity and sensible scheduling will limit public concern. Vegetation Management Plan Figure 11 - Vegetation Management divides the park into several zones. Each zone is described by: • a letter/number code. • a phase number. • an approximate acreage figure. The first part of the code describes the ecological community (e.g. WO = Woodland - Mixed Hardwood, P = Prairie, S = Savannah, etc.). The second part of the code is an alphabetical letter which describes the method of restoring or managing the ecological zone. These methods are described in detail below. The third part of the code is a number which describes the priority of the zone for management/restoration. Zone 1 is the highest priority within a particular ecological community and Zone 9 is the lowest. Ytg=12 - Vegetation Management Phasing Program describes phasing in more detail. Prairie Areas (Method A or P -A-#) The City should hire a firm specializing in prairie restorations such as Prairie Restorations of Zimmerman, Minnesota or Prairie Nursery of Winona, Minnesota. These firms offer advice and a range of services including burning and planting. Make sure the chosen firm uses prairie seed collected within a 200 mile radius of Rosemount. Non-native seeds can be aggressive, resulting in one or two species dominating the site. Can-olls Woods Nature Area 1-7 Mow fire breaks around the perimeter of the future prairie areas. The experts from the prairie restoration firms will recommend the best technique for restoring the prairie grasses and forbes appropriate to each particular microlite. The nursery may recommend burning the entire prairie - designated area to see what surprises the seed bank in the soil holds. Prairie seed can lie dormant for years in the soil. Next, the experts may recommend one or two general or local applications of Round -Up. This herbicide will kill all vegetation. The next step is to use a Truax Drill to plant seeds of prairie grasses. The following year the restoration firm may mow and plant by hand forbes or wildflowers (1000/acre). In the beginning a prairie should be burned every year in order to eliminate weeds and the woody plant materials which naturally invade an open site. Burning also creates spectacular wildflower displays. Once established, a prairie should be burned every 3-5 years. Recreated Oak Savannah (Method A or S-A-#) In these designated savannah areas, mow 10-15 foot fire breaks around the edges to prevent the fire from jumping into the adjacent woods. Hire a prairie restoration firm. Restore prairie. Once the prairie community is established, tree spade in small Bur Oaks ( 2• -3" diameter at breast height). Plant the Bur Oaks in clusters or as isolated species 150-200 feet apart. The City can reduce costs by transplanting Bur Oaks from other City property or by donation from private property. This transplanting can occur over a period of years. Examine the transplanted trees after one season. If they are doing well, leave them be. If they appear sick, cut the trunks off around 6-12 inches above ground. The Bur Oaks should sprout from the base. After 2-3 years, select a main leader and prune off the rest. The Bur Oaks seedlings will need Tubex Tree Shelters (@$5.00 apiece installed) to protect them from deer browsing. Initially, a savannah should be burned annually. The young Bur Oaks need protection from the heat of the fire. Mow a 16 foot diameter circle around each oak to protect it from damage. Once sufficient shade is established, plant the forbes and grasses unique to a savannah community. City of Rosemount Restored Oak Savannahs (Method B or S -B-#) Oak Savannahs are more easily restored than created from scratch. A few savannah type trees exist along the northern edge of the Carrolls Wood. These are Bur Oaks with well -formed rounded canopies; they look like they have always grown in the open rather than in cramped forest conditions. Mature Bur Oak have thick corky bark which makes them resistant to quick ground fires common to prairies. In the designated savannah areas, mow 10-15 foot fire breaks around the edges to prevent the fire from jumping into the woods. The City should also hire a prairie restoration firm to assist in restoration of prairie grasses and forbes within the savannah areas. In the fall cut and remove undergrowth (usually Buckthorn). Paint the herbicide Garlon on cut surfaces of stems. The next spring, bum. Because of lack of fuel it may take a few years to get a complete bum. Savannah - type grasses and forbes should start to reappear. After an area is burned, seed in handfuls of grasses and forbes (seeds and berries) appropriate to an oak savannah. The prairie restoration firm can provide some of these species. Others may have to be collected by volunteers from local areas. Initially a restored savannah should be burned every years. Once the understory of desired species is established, the burning can be done every three to five years and eventually once every ten to fifteen years. Oak Woodland (Method A or WO -A-#) This restoration method is for degraded woods (see Figure & Site Analysis) with a sparse canopy or isolated mature trees @ 150-200+ . feet apart. The understory is a impenetrable wall of Buckthorn. These woodland areas will be the most costly and exasperating to restore. This method of management is geared towards eliminating the dense understory of Buckthorn and replacing it with more desirable species. This is a multiyear process because Buckthorn is a prolific seeder. Year One: In the fall or winter, cut and remove adult Buckthorn (any stem over ; inch in diameter if possible). Treat the cut stems with Garlon. This phase will eliminate 90-95% of the Buckthorn biomass. It is extremely labor intensive (Rosemount may want to organize volunteer help. A person licensed to apply herbicides must be in charge of Carrolls Woods Nature Area training and overseeing the volunteer help.) Year Two: Plant 75 saplings per acre. Plant Red Oak, White Oak, Black Cherry, and Green Ash. Use the Tubex 5' tree shelters for these saplings. These tubes will serve 3 functions: • protect the saplings from rodents and deer • create condensation which will help the saplings survive the drought -prone soils. • protect the saplings from herbicide sprays. After planting, use a foliar spray (such as Krenite or Round -up) to kill off all the Buckthorn seedlings. These sprays will kill any green growing plant that they contact. Buckthorn remains green and growing in the forest 2-14 days after most native vegetation goes dormant in the autumn. This time may be the best time to spray in order to preserve as much non -Buckthorn understory vegetation as possible. Rosemount will need expert advice from the herbicide distributor as to timing of application (the window of opportunity varies from year to year and can be quite small). Year Three: Apply a foliar spray again to eliminate any remaining Buckthorn seedlings. Seed each acre with acorns or plant oak/cherry seedlings (2000/acre). The DNR sells 1000 tree seedlings for $150. Acorns are not available commercially; collecting them could be a volunteer effort in early to mid August. One drawback for acorns is that not every year is a productive year for oaks to produce them. Subsequent years: Monitor the restored areas for buckthorn regeneration. Continue to eliminate either by cutting and applying Garlon to the cut stems or by using foliar sprays for pockets of infestation. Oak Woodland (Method B or WO -B-#) This management method is for pleasant woods (see Figure & Site Analysis) with a well-developed canopy of mature trees and a moderate Buckthorn understory. Management efforts should be directed at eliminating Buckthorn, especially the mature individuals and ones in the occasional openings in the canopy, and supplementing the planting especially in openings. Year One: Cut and remove adult Buckthorn (over � inch in diameter). Apply Garlon to cut stems. Replace the Buckthorn with tree saplings or shade -tolerant shrubs. Possible species: Common or Scarlet Elderberry (Sambucus eanadensis or pubens) City of Rosemount American Hazelnut (Corylus americana) Nannyberry (Viburnum lentago) Gray Dogwood (Comus racemosa) Pagoda Dogwood (Comus alternifolia) Round -Leafed Dogwood (Cornus rugosa) Serviceberry (Amelanchier canadensis) Gooseberry (Ribes cynosbati) Raspberry (Rubus strigosus) Prickly Ash (Zanthoxylum americana) Green Ash (Fraxinus pennsylvanica) Red Oak (Quercus rubra) Northern Pin Oak (Quercus ellipsoidalis) White Oak (Quercus alba) Black Cherry (Prunus serotina) Hackberry (Celtis occidentalis) If there are any large openings in these zones with solid stands of Buckthorn, eliminate using Method A. Year Two: Monitor these zones, cut and apply Garlon to any remaining Buckthorn. Continue to add shrubs and saplings if needed. Begin to enrich the herbaceous layer in shady areas with appropriate wildflowers. Oak Woodland (Method C) This restoration method is for north -facing slopes with an open canopy and a fairly dense understory of Buckthorn. For areas without canopy trees and heavy Buckthorn, use Method A. When planting, use the species listed below. For areas with canopy trees and some Buckthorn, use Method B. Species to plant: Sugar Maple (Acer saccharum) Basswood (Tilia americana) Ironwood (Ostrya virginiana) Black Cherry (Prunus serotina) Hackberry (Celtic occidentalis) Red Oak (Quercus rubra) Butternut (Juglans cinera) Black Walnut (Juglans nigra) As the Buckthorn is eliminated and the canopy begins to fill in, enrich the forest floor with wildflowers called spring ephemerals. Lowland Woods (WL) These small areas of the site are disturbed frequently by groundwater or wet soil conditions. This community will not require much management except to prevent disturbance of the drainage systems and to eliminate infestations of Buckthorn. Successional Woods (WS) Successional forest: these areas are dominated by pioneering plants and have few mature trees and a dense understory of a variety of species. The only management needed for these areas is to control Buckthorn invasions. Woodland Pothole The area in the southwest comer of Carrolls Woods was once quite productive waterfowl habitat. In the last twenty years it has silted in and become dry enough for Silver Maples to grow. To make the area a pothole again, it must be dredged, regraded, and perhaps sealed to prevent water from seeping away. If possible the City should construct a small siltation pond to filter all stormwater runoff before it enters the pothole. Once open water is provided, the bird (and animal) life will return. Schwarz Pond The fluctuations in water levels for this pond actually increase its productivity as a food source for waterfowl. Discontinuing mowing and planting prairie would improve this area as habitat for birds and animals. Some wildlife plantings along the fence will help screen it. The City or school should monitor water quality in future years. Wildlife Habitat Program One of the primary objectives for this park is to establish diverse wildlife habitat which provides food, water, and shelter for a variety of wildlife species. Although the pallet of plants included in the Vegetation Management Program for the park will provide habitat for several wildlife species, a wildlife management program will add extra components to improve the diversity of species using the nature area. A number of state and regional resources are available to help develop a wildlife habitat and management program. The Minnesota Department of Natural Resources (D.N.R.) have individuals with expertise necessary to: • evaluate existing habitat and its potential to support wildlife. Carrolls Woods Nature Area City of Rosemount am • recommend habitat development programs to improve the habitat that is already present. • identify the bearing capacity of the park and ways to maintain a healthy wildlife population. The City should contact the D.N.R. Section of Wildlife prior to future development to insure that no opportunities are missed along the way. Based on the DN.R: s guidelines, fifteen components of wildlife habitat are necessary to fulfill the major needs of most species. Eight of these components are plants and eight are structural or non -living components. Plant Components: • grasses/legumes • butterfly, bees, moth plants • hummingbird plants • summer plants • fall plants • winter plants • nut/acorn trees Structural Components: • feeders • water • dust beds/grit • salt • cut banks/cliffs/banks • brush/rock piles snags • nest boxes By providing these components, the community will improve the chances of wildlife flourishing within the confines of this nature area. Cost Estimate and General Phasing Program Although certainly not an exact science, estimating or projecting the costs to develop this park is important because it provides the citizens of the community, governing bodies, and City staff with a basic understanding of the economic commitment necessary to put the park's Master Plan into effect. The estimated costs to develop the park will affect priorities for adding the various components and amenities and in deciding which ones are best accomplished through volunteer efforts versus paid contracts. The City and Advisory Committee should use the figures below only as "benchmarks" to compare the relative costs of items and for budgeting purposes. Actual cost to acquire land and develop the Master Plan will depend a great deal on: • the actual land values at the time of acquisition. the actual construction costs at the time of development. • how much of the costs for development can be offset through alternative funding programs, such as volunteerism, grants, donations, etc. The cost estimates below are based on estimated land values in 1991 dollars (determined by the City) and typical development costs in 1991 dollars (as determined by industry cost -to -construct averages, i.e. what it would typically cost, on average, for a contractor to come in and do the work). Park Land Acquisition Costs The Master Plan includes two parcels of land which the City does not currently own. The first parcel (Parcel C) has the highest priority for acquisition because it plays an critical role in the long term objectives of the Master Plan. Based on current land prices in the City of $8,000 to $11,000 per acre, the cost for the 15 acres identified in the master plan would range from $120,000 to $165,000. The second parcel (Parcel D) plays an important secondary role in the long term objectives of the Master Plan. It provides an area for support facilities (e.g., parking lot) and neighborhood recreational facilities. Again based on current land prices in the City of $8,000 to $11,000 per acre, the cost for the 7 acres identified in the master plan would range from $56,000 to $77,000. Although these two parcels play an important role in the park's Master Plan, they may not be either available for purchase or the City may not be able to fund their acquisition. If this becomes the case, the overall integrity of the Master Plan is not lost. Even without these parcels, the park will be a priceless natural resource and will make a significant contribution to the park system within the community. However, if the vision of this master planning process is to be realized, every effort should be made to include these parcels within the park. Carrolls Woods Nature Area City of Rosemount ,L Park Development Costs The cost estimate and general phasing program for developing the park is illustrated in Figure 13 Cost Estimate and General Phasing Program. The suggested phasing is based on the most reasonable approach to the park's future development. The vegetative management programs are the top priorities. The auxiliary site amenities can be added in the future. The phasing program is based on the best judgements given current conditions. Since conditions and opportunities often change over time, the City and Advisory Committee should review the phasing program on a periodic basis to change priorities if necessary. Interpretive/Education Programs One of the important program elements for this park is the an interpretive and environmental education program to emphasize the importance of preservation and conservation of limited natural resources. The programs should focus on native plant communities, how they evolve and maintain themselves, and on the wildlife which depend on them for survival. These programs should also emphasize the use of native plants around homes and the benefits they provide, both in an aesthetic and practical sense (such as wind screening, shade, attraction to wildlife, etc.). Environmental education programs for elementary and secondary schools should be a high priority, considering the park's proximity to the nearby schools. The Minnesota Department of Education often assists communities in developing environmental educational programs. State personnel, along with local school district staff, should be contacted and asked to help create these programs. Interpretive programs should be created to reach a wide variety of people and age groups. Interpretive programs typically focus on providing park visitors with information about the plant communities and wildlife within the park. These programs often include: • interpretive nodes (low profile kiosks with interpretive panels). • interpretive signs throughout the park which describes different features. maps and handouts with text describing the park's ecological systems, wildlife, geology, etc. Development of interpretive programs should also include the Minnesota Department of Education, local school district staff, as well as a naturalist and other environmental professionals. Existing Community Programs This Master Plan does not intend to exclude existing and successful community programs from taking place within park boundaries. However these programs should occur only if they do not cause any negative impacts on the park's natural character. Organized events bring visitors to the park and create experiences which give people a vested interest in the future of the park. A pleasant memory of a place can motivate people to protect it as a resource. As an example, there is no compelling reason why the Haunted Woods program should not continue as it. has in the past as long as its organizers take reasonable care to protect fragile plant life from damage. To accomplish this, organizers of community programs should work closely with the Advisory Committee in selecting a route and location for props. In the future, when the nature area is fully restored and developed, the Haunted Woods program may be better suited to another location. The organizers should work with the Parks and Recreation Committee and city staff in the next few years to see if another more suitable site exists. In the interim, the Haunted Woods program should continue. Advisory Committee The City should establish an advisory committee to oversee and guide the future development and protection of Carrolls Woods Nature Area. The Committee should be made up of individuals with different backgrounds who can help give direction and motivation to the community in support of the park's Master Plan. The Advisory Committee should work directly with the Parks & Recreation Committee and City staff to guarantee that the park's best interests are served. The City Council should formally accept the Advisory Committee in ,an advisory role and as the guiding force behind the park's future development in order to add strength to Advisory Committee's position. Carrolls Woods Nature Area City of Rosemount The Committee's make-up should include: • local citizens who are concerned about the park's future and want to contribute their energies toward insuring that its mission is carried out. • members of local conservation organizations with interest and expertise in native habitat, wildlife observation and wildflower gardening. • members of local garden club(s) who have a special interest in native plants and gardening. • teachers in the local educational community who have an interest in environmental education and interpretation. • community leaders who can provide political guidance and potential sources of private funding. • a City staff member(s) to assist in guiding the project through administrative and political channels. The Advisory Committee's involvement in the development of the park should occur prior to the design development stage of the project. The Advisory Committee should use the Master Plan as a guide to any development within the park. Other key responsibilities for the Committee include: • interpreting the master plan document, including periodic review of the plan itself and the priorities for phasing. • implementing the plan, including scheduling of improvements, securing professional assistance as necessary, and making recommendations to the Parks & Recreation Committee, City st4 and City Council. • initiating education and interpretive programs. • initiating public awareness programs and public meeting to keep the citizens of Rosemount aware of the park's development. • initiating volunteer programs to assist in the development of the park and reduce development costs. • providing on-going guidance and support to volunteer and educational programs to insure the long-term success of the park. • monitoring maintenance practices so that they stay within the intent of the Master Plan. monitoring existing community programs (such as the Haunted Woods) and work with program organizers to guarantee that the best interests of the park are served. Carrolls Woods Nature Area 1 -r Conclusion The citizens of Rosemount should commend its City Council, Park and Recreation Committee, and the Advisory Committee for their concern in planning for such a valuable community resource as the Carrolls Woods Nature Area. The Advisory Committee especially put in many hours debating the issues facing this park and came to some tough and critical decisions about its future.
