R-2, Single Family attached Residential (Outlot B); IP, Industrial Park (Outlot Q. R-2, Single Family attached Residential overall. UR, Urban Residential. Affirmative recommendation for both the rezoning and the PUD final plan / preliminary plat Mr. Gary Grant of Pulte Homes has requested approval of a PUD final development plan, preliminary plat and rezoning for the former University of Minnesota property based upon the concept that was approved on September 17, 1996. The new plan eliminates a twin home element contained in the concept and concentrates on "detached townhomes" (small homes on fifty foot lots), and "club homes" (single level townhomes typically in unit clusters of four). On August 12, 1997, the Planning Commission conducted a public hearing as required and received comments from residents of the neighborhood. Several residents were concerned about the spacing between the units, berms and landscaping, and the transition to townhouse housing types. Speculative comments were made about property values, appreciation and comparisons with traditional single family detached housing. The impact of the anticipated tree removal also generated concern. Several comments in favor of the development were also received. After considerable discussion regarding strict adherence to the tree preservation ordinance, building setbacks and street alignment; the Planning Commission unanimously recommended in favor of the rezoning and the PUD final plan / preliminary plat. Additional discussion of the Tree Preservation ordinance including the City Attorney's recommendation is provided in the attached memo. RECOMMENDED ACTION: Motion to adopt an ordinance rezoning Outlot C, University Addition to R-2, Single Family Attached Residential; ;u` -,CIO-T-1.-t-\ - and - Motion to adopt a resolution approving the planned unit development final plan and preliminary plat for Pulte Homes of Minnesota. COUNCIL ACTION: MEMORANDUM TO: Mayor, City Council members FROM: Rick Pearson, City Planner DATE: August 28, 1997 RE: Pulte Homes "The Enclave" Tree Preservation Ordinance Implementation On August 12, 1997, the Planning Commission adopted a motion to recommend approval of the Pulte Homes PUD final development plan called "The Enclave" with conditions. During and after the public hearing, the potentially enormous numbers of replacement trees associated with the implementation of the tree preservation ordinance was extensively discussed by the Commission, Developer and Staff. However, no alternatives were included in the resulting Planning Commission recommendation of approval. The Developer has requested that several considerations be made by the City Council relative to the replacement requirements specified by the ordinance. The City Attorney has reviewed the situation and has advised staff to consider a reasonable approach that does not mandate off-site replacement plantings. As a result, Staff is offering further analysis and implementation options for the Council's consideration. Existing Trees The trees consist of primarily Jack Pines arranged in a double shelter belt with very tight spacing intervals. Many of the trees are six to eight feet apart which is less than half the appropriate spacing for the trees in their mature form. Generally, the pines are in obvious decline, having reached their maximum growth potential and are suffering from nutrient competition as a result of the tight spacing. The lack of vegetation in the interior of the tree stands result from shade intolerance. Jack Pines are native to northern Minnesota and are often found in swampy boreal forests, typically north of the deciduous "big tree" forests. The development area in Rosemount is more likely to consist of oak savanna and short grass prairie ecosystems. The small number of Box Elder, Cottonwood, Elm and a few Oak saplings observed are more likely to be naturally occurring than the Jack Pine in the absence of agricultural cultivation. Tree Preservation The Planning Commission review memo for August 12, 1997 discussed the significant tree replacement requirement based upon a rather strict interpretation of the ordinance. Flexibility with interpretation may be necessary in light of the City Attorney's opinion of this first application of the tree preservation ordinance standards. In essence, the 1900 trees required would more than cover the entire site if properly spaced, thus eliminating the ability to reasonably develop the site. The strategy of planting trees off-site under the direction of staff was a good idea until recently reviewed case law revealed that a direct connection or "nexus" is required between the off-site tree plantings and the Pulte development. This means that it might be acceptable if some trees are planted in Biscayne Park a few hundred feet away. However, requiring the developer to plant large numbers of trees across town would probably be indefensible in court if challenged. These discussions have resulted in the following three apparent options. Option #1, 4:1 Replacement of Individual Significant Trees Strict interpretation and implementation of the ordinance based upon the four per one replacement requirement with consideration given to the relative quality of the existing trees. This means that of the 1,500 existing trees, a 25% credit is automatically applied for grading, drainage, utilities, etc. Another credit for the relative quality or health of the trees is applied. The original staff assessment of 30% credit for unhealthy or declining trees may be low. If 50% is used, the replacement number still reaches 1,300 which would cover over 22 acres of the 35 acre property with trees. This method of calculation would be considered as a "taking" by the developer. Option #2, Woodland Replacement in Area The ordinance actually requires that the square footage of woodlands be replaced as an alternative to counting individual trees in densely wooded areas. This solution is the most practical approach. Crediting the shelter belt massings as a woodland results in a massing of 177,670 sq. ft. of woodland in addition to isolated trees beyond the massings that would utilize the formula in option #1 above. Given a reasonable 750 sq. ft. of area for each tree, the required replacement is 237 trees for the woodland replacement requirement. The replacement requirement for the individual or "isolated trees" is 92, based upon a 2:1 or 4:1 replacement ratio as required. The resulting total replacement requirement is 329 trees. Option #3, Modify the Ordinance The City Attorney suggested that a ceiling for replacement requirements should be considered in order to avoid a developer's claim for a "taking". The common sense approach is to ensure that the intent of the ordinance is implemented without exacting a punitive replacement requirement which precludes any development. Lacking the ability to purchase all of the wooded developable land within the city results in the attorney's strong recommendation to pursue option #2 for the Pulte Homes proposal, and utilize that strategy in all cases until such time as the ordinance may be modified. RECOMMENDATION Staff is recommending the second option is most appropriate implementation of the tree preservation ordinance relative to the Pulte Homes proposal. Pursuant to the abovementioned Option 92, the tree replacement requirement for the Pulte Homes "The Enclave" is 329 trees in addition to the normal requirement for R-2, Single Family attached Residential District. This calculation is based upon shade trees only. Staff will calculate the areas of evergreen and ornamental trees for a comparison to the Pulte landscape plan in time for Tuesday's meeting.

Public Hearing: The Enclave -Residential Final PUD, Preliminary Plat and Rezoning Chairperson Droste opened the public hearing for The Enclave -Residential Final PUD, Preliminary Plat and Rezoning. The recording secretary has placed the Affidavit of Publication and Affidavit of Mailing and Posting of a Public Hearing Notice on file with the City. Mr. Pearson presented the application of Pulte Homes to develop the 35 acres formerly owned by the University of Minnesota located between CSAH 42 and the Biscayne Way area. The concept was previously approved for 126 units including detached, twinhome and townhome units. Pulte Homes is proposing 56 detached townhomes and 72 rambler style townhouse units. The detached townhomes border the existing neighborhood, providing a transition from detached to attached dwellings. Density is less than 4 du/acre. The development has a public through street with two cul-de-sacs which connects Biscayne Avenue and 145th Street. A second connection to Biscayne Avenue is via a private street. Due to a pipeline easement, the through street is located in an area which will result in significant tree loss. The developer has performed a tree inventory, and City Staff has inspected the area to determine the extent of unhealthy trees. From this initial review, it appears the developer's responsibility for tree replacement is 1,900 trees. The corner lots at the entrances to the cul-de-sacs will require variances for 20' additional setback (rather than the required 30'). There is an issue with snow removal and storage and consideration could be given to grouping or sharing driveways. Sidewalks or trails will be located on both 145th Street West and Biscayne Avenue to provide pedestrian access to Biscayne Park. In addition, park dedication fees paid by the developer will be used for improvements to Biscayne Park. Commissioners discussed the tree replacement issue, suggesting that trees be planted elsewhere in the City if there is limited space for plantings within the development. Trees must be replaced with similar types of trees. The developer will be establishing a new shelter belt along CSAH 42. Chairperson Droste opened the floor to the applicant. Planning Commission Regular Meeting Minutes August 12, 1997 Page 5 Gary Grant, Vice President of Construction for Pulte Homes was present at the meeting. Mr. Grant presented a history of the company. The targeted market for this development will be baby boomer age and older. Dennis Griswald was also present on behalf of Pulte Homes. Mr. Griswald indicated they are attempting to save trees along Biscayne and some maples along 145th Street. A large number of trees will be planted along the north perimeter of the property, together with berming. Plantings will also be along CSAH 42 and the right-of-way easement, along Biscayne and 145th St. There will be 722 trees planted, replacing existing trees which are near the end of their growth cycle. Based upon their inventory, 650 trees will be removed. While a tot lot was recommended by the City for the open space, the developer would prefer to put in a picnic area and gazebo, which would more closely meet the needs of the potential buyers. The entire area will be governed by an Association. The developer held a neighborhood meeting last week, which was attended by 5 residents. Commissioner DeBettignies, addressing the snow removal and storage issue, asked why the through street is not private and maintained by the Association. Mr. Pearson explained Public Works recommended that, because the street connects two collector streets, it should be public. The street will be built to standard width. 12 foot wide driveways are recommended in the cul-de-sacs. Because the majority of the street is not double loaded, snow removal should be comparable to a conventional street with driveways on both sides. The interior streets will be maintained by the Association. Mr. Litterer suggested combining two driveways into one 24' wide driveway. Mr. Grant indicated the developer prefers 16' wide driveways. Commissioner Shoe -Corrigan expressed concern that snow buildup could cause visibility problems. There was further discussion concerning application of the Tree Preservation Ordinance. Mr. Pearson indicated he estimates 30% of the trees were past the growth cycle or unhealthy. Mr. Pearson also indicated the tree ordinance was not in place when the concept was approved. Commissioner Weisensel confirmed all structures will be slab -on -grade. Mr. Grant indicated the potential buyer does not wish to incur the additional cost for a basement. All storage is in the garage. No storage sheds are allowed. Chairperson Droste opened the floor to the public. Norman Timmer, 14625 Biscayne Way, indicated he has no problem with removal of the trees. He feels they will be replaced with better plantings. Marlin Rechtzigel, 14727 Clayton Avenue, claims the subject property was confiscated from his neighbors for the war effort and was later sold to the University. Since then the property has been contaminated by the University. This property should be turned back to the public. Although the development appears to be a nice project, it should not be placed where the property owner was forced to sell. Mr. Rechtzigel cannot sell his property because of the contamination, and now the City is encouraging development of the property. Planning Commission Regular Meeting Minutes August 12, 1997 Page 6 Scott Baldwin, 14555 Biscayne Way, disagrees on the tree issue, claiming the trees are 50 years old and have created their own ecosystem. Mr. Baldwin further indicated the townhome units do not appreciate in value like detached homes. The existing neighborhood has small children, which would not mix with the proposed plan. The developer is cramming in too many lots. There are two structures behind his home. There will be increased traffic to Biscayne Park and people will be forced to walk on the street. Without basements under the units, there is a concern for shelter during severe weather. Paul Wrolstad, 14545 Biscayne Way, is concerned about the width of the lots. Traffic on 42 will see it as single family detached homes, not townhomes, on very narrow lots. There is more than 30% coverage on these small lots. Mr. Pearson responded that the PUD R-2 requirements do not require 30% coverage for twinhomes, and this issue does not come into play for the detached units. Mr. Wrolstad was also concerned about the lack of shelter in severe weather. Dean Carlson, 14699 Biscayne Way, favors the development. As long as the property has to be developed, he would prefer to see this type of development occur. Nancy Cisewski, 14675 Biscayne Way, asked how high the berms will be. The berms will be 2'-4' with trees planted on top. Ms. Cisewski also wondered how this will affect their taxes. Mr. Pearson indicated the County looks at an individual property and not adjacent properties when determining taxes, and instructed Ms. Cisewski to verify this with the County Assessor's office. Ms. Cisewski stated that, although she would prefer to see the property remain public land or have more open space, the plan is acceptable. Gale LaFavor, 14635 Biscayne Way, would prefer to see the homes further apart. Katie LaFavor, 14635 Biscayne Way, asked how far the houses are from the rear property line. Mr. Pearson indicated the detached dwellings have the same setback requirements as typical single family lots. The homes are 30' from the rear property line. Rhonda Baldwin, 14555 Biscayne Way, would like to see the developer work around the trees and not disturb the wildlife. The lot sizes should blend with the existing neighborhood. Marlin Rechtzigel, 14727 Clayton Avenue, restated his claim that this is stolen property. Anyone involved in its sale is an accessory to the crime. The property should be public land. Mr. Pearson explained to Mr. Rechtzigel that the issue before the Planning Commission is not the sale of the land. The City has no authority over the transfer of ownership of land. MOTION by Droste to close the public hearing. Seconded by Tentinger. Ayes: Droste, Shoe - Corrigan, Weisensel, DeBettignies, and Tentinger. Nays: 0. Motion carred. Commissioner DeBettignies addressed neighbors' concerns regarding severe weather shelter. There are no state statutes which require the developer to provide shelters. Planning Commission Regular Meeting Minutes August 12,1997 Page 7 There were further discussions concerning the streets. Mr. Pearson indicated the streets are aligned for future expansion and designed to avoid offsetting intersections. 145th Street will be upgraded. Additionally, new sidewalks will provide pedestrian access to the park. Commissioner Tentinger asked whether the through street could be moved north, enlarging the Outlot A area. Mr. Griswald indicated there would be a facility in the outlot area for the residents. Back to back yards are more feasible. There is a possibility the road could be moved approximately 10' south. Commissioner Tentinger further asked if the developer would consider expanding the lots wider. Mr. Griswald responded the tree situation reduces the buildable lots. To maintain balance and project viability, wider lots are not possible. Mr. Pearson further indicated the building mass will provide buffer to the existing neighborhood from CSAH 42. Chairperson Droste pointed out the original concept allowed 126 units, the developer is proposing 128 units. If 2 units were dropped, 5' would be added to the lots. Mr. Grant indicated there is no flexibility in lot reduction. Compared to existing developments in other cities of detached townhomes, lots run 40'-50'. Commissioner Shoe -Corrigan indicated she likes the concept plan. There is transition between the existing homes and CSAH 42. She questions, however, the intentions of the developer as concerns the tree replacement. The developer previously asked for flexibility in the replacement of trees. The Tree Preservation Ordinance is fair, and the developer has a responsibility to the community to follow the regulations. The developer should be given credit for unhealthy trees, to be determined by Staff. She supports the plan, provided there is no compromise on tree replacement. If the ordinance is not strictly followed, she will not support the concept plan. Mr. Grant stated the developer will work with Staff to determine the number of unhealthy trees. They asked for flexibility in that determination, not in compliance with the Tree Preservation Ordinance. Commissioner Weisensel noted this is the City's first experience with the Tree Preservation Ordinance. Compliance must be scrutinized very carefully. He does not agreed with the slab -on - grade and lack of demand for basements. Further, Commissioner Weisensel indicated it is not unreasonable to drop three units from the plan to get wider lots for more green space. Chairperson Droste also wants the tree ordinance followed. Commissioner DeBettignies supports the plan and the landscape plan. Setbacks are close to what you find in R-1, and the plan is more consistent in density with R-1 than standard R-2. There was confusion regarding the side setbacks. The plans reflect 10' side yard setbacks, however, Mr. Griswald explained the garage side has a 5' setback.

Pulte Homes has come forward to pursue their interest in developing the property. Subsequently, the Dakota County Highway Department purchased approximately one acre of land along CSAH 42 near the eastern approach to Biscayne Avenue. The concept approval was conditioned on: 1. Amending the Comprehensive Guide Plan to place the property within the MUSA. The recent Comp. Guide Plan Amendment which expanded the MUSA included this property. 2. Rezoning the southerly 980 feet of the property to R-2, Single Family attached Residential. A rezoning application is included with the current submission. 3. Provision of buffering or screening between the existing homes and the proposed development. The grading plan indicates proposed berm ing and the landscaping plan details screening plantings 4. Reduction of potential setback variances for dwelling units adjacent to the existing neighborhood. The Plan submitted for Pulte Homes accomplished this objective. 5. Incorporation of recommendations relative to grading, street design and utilities by the Public Works Department. The attached Public Works/Engineering memo details specific issues and the attached recommendation is included as part of the recommended action. ACCESS & CIRCULATION The dominant feature of this development is the through street that parallels Biscayne Way with two of the three access points, connecting Biscayne Avenue with 145th Street West. This street which includes two small cul-de-sacs will be a public street with 60 ft. right-of-way width.. The remaining streets serving the townhouses will be private, consisting of a loop off of the through street and two cul-de-sacs. A second connection to Biscayne Avenue occurs via this private system. The curb cuts on Biscayne Avenue are in place as a result of the recent Biscayne Pulte Homes "The Enclave" August 12, 1997 Page 2. Avenue improvements. These entrances align with the Eastbridge entrances, west of Biscayne Avenue. HOUSING CHARACTERISTICS Detached Townhomes: These structures consist of two types, a two story and a single story version with both being slab -on -grade. Both units have attached two car garages. Face brick is used about the first floor front facade including entry areas and garages. Elsewhere, vinyl siding is used. Club home Townhomes: The attached single -level townhomes combine three different models typically within four unit building clusters. The two interior units are unique with the end units being "mirror -opposites". As above, face brick is proposed for the front facades, entry areas and garage fronts. Also as above, all units have two car garages. All of the units have driveway parking infront of each unit. The club homes have twenty five feet of driveway between the curb and the garages, and the detached townhomes have thirty feet of front yard setback which includes driveways. LANDSCAPING Given the extent of the property covered by pipeline easements, landscaping is typically concentrated about the outer edges of the development for buffering or screening purposes. Additionally, each detached townhouse unit has a boulevard tree within the lot frontage. The club homes have at least one tree per unit mixed between boulevard, back yard shade, and ornamental or screening trees. Foundation plantings will also be provided. TREE PRESERVATION The proposal presents the first application of the tree preservation ordinance to a property that has large numbers of significant trees that will be removed if the development is approved. Large numbers of pines have been planted in what appears to be a multiple layered shelter -belt. The uniformity of age, size, spacing and species supports a conclusion that few if any of the plantings are naturally occurring. Because of the shelter -belt pattern, the trees are generally too close together with nutrient competition as the result. The pines are generally not shade tolerant which results in the lack of leaves or needles in the interior of the tree stands. However, in spite of the origin or purpose of the trees, they still provide a very attractive amenity for the area if not the type of wildlife habitat usually created by more diverse and naturally occurring woodland. The intent of the ordinance is to discourage removal of significant trees and woodlands with strong replacement requirements. Unfortunately for the Developer, the irregularity of the Pulte Homes "The Enclave" August 12, 1997 Page 3. property shape and the pipeline easements place the only public through -street location directly upon the shelter -belt location. As a result, only approximately ten percent of the estimated 1,500 trees on the site may be spared. While the overall density of the development is relatively low, almost all of the land outside of the pipeline easements is affected because of the housing pattern. Except for reducing the density, concentrating units by stacking at the same overall density is the only way to save additional trees. Furthermore, no trees would be saved by a shift to a conventional R-1, Single Family detached pattern because of the right-of-way location. In any event, a conservative estimate of the additional trees required of the developer is over 1,900 trees. Most of the trees are considered significant and require four trees to be planted to replace significant coniferous trees exceeding 12 ft. in height. This number allows a credit for an initial 25% reduction because of drainage, utilities and right-of-way needs allowed by the ordinance. In addition, a credit of 30% is given for the interior trees greatly denuded of vegetation deemed to be "unhealthy". Last (but not least), another credit was given for the almost 600 trees proposed by the developer in the landscaping plan which exceeds minimum requirements. The tree preservation ordinance does provide an alternative means of calculating the replacement requirement in the case of woodland replacement. The square footage of the woodland area can be calculated and replaced on a "one per one" basis. Typically, trees would not be planted as close together as they have been in this shelter -belt, thus reducing the nutrient and sunlight competition amongst the replacements. Staff will have comparisons available for discussion at Tuesday's meeting. Various options for tree preservation were discussed between staff and the developer. Pockets and edges of existing trees, at a minimum were identified as important and feasible. The developer may provide additional information regarding additional efforts to preserve existing trees. Due in part to the approved concept plan and site constraints, however, the replacement penalty is being chosen by the developer. OTHER CONSIDERATIONS Four variances have been identified, one on each corner lot at the entrances to the two cul-de- sacs in the detached townhome area. The street -side side lots are shown with twenty foot setbacks instead of the standard thirty feet. Variances can be granted via the PUD process based upon findings (see attached). The Park and Recreation Committee will recommend that sidewalks or trails be located on both 145th Street West and Biscayne Avenue to provide pedestrian access to Biscayne Park which is the designated neighborhood park intended to serve this development. In addition, a sidewalk Pulte Homes "The Enclave" August 12, 1997 Page 4. will be located on one side of the through -street for pedestrian access to both Biscayne Avenue and 145th Street West. In addition, a private tot lot is recommended for the proposed Outlot A. SUMMARY The PUD final development plan and preliminary plat offers an apparently high quality single level townhome project intended for "empty -nesters" (or active adults) coupled with a new housing type to Rosemount, detached townhomes. The arrangement offers a transition of housing types with the detached units separating the existing single family neighborhood from the attached townhome area. Although new to Rosemount, Pulte Homes has a reputation for quality product. The development site challenges the developer with an irregular shape, few alternatives for street design and lastly, pipeline easements along the longest contiguous outer edge of the property. Strict adherence to the tree preservation ordinance replacement requirements may be difficult for the developer to accept. The Planning Commission may consider offering a separate recommendation to the City Council regarding possible alternatives after discussion.

Incorporation of recommendations relative to County State Aid Highway 42 by the Dakota County Plat Commission; and 3. Developer must make payment to the City at the time of final plat for the following items: a. Preliminary payment for future improvements to 145th Street West, including street and trail estimated at this time in the amount of $50,812.80; b. Preliminary payment for future trunk watermain improvements on 145th Street West estimated at this time in the amount of $10,251; C. 1997 Storm Sewer Trunk Area Charges at $2,530 per acre which is estimated at this time in the amount of $89,056 (Based on 35.2 acres); and d. 1997 Geographic Information System (GIS) fees at $50 per lot/unit estimated at this time in the amount of $6,400 (Based on 128 units). The following is a review by the Public Works/Engineering Department of the Preliminary Plat plans received by the Public Works/Engineering Department on July 24, 1997. The street & utilities will have to be done as a public improvement. The Developer can also petition for the site grading to be done as a public improvement. Grading/Drainage Facilities/Water Resources Site drainage is generally from the northerly portion to the southerly portion of the site. Runoff from this site would be directed by existing storm sewers to the pond on the north side of County 42 which is across the road from the Rosemount Business Park. Storm sewer stubs off a trunk storm sewer on Biscayne Avenue were provided to serve this development. The City's 2nd Draft of the SWMP (2/97) indicates that no ponding is necessary on this site. Directing post development runoff from this site to the County 42 ditch system is not desirable and could be prohibited by the County or City. The Grading Plan submitted in the preliminary plat package will be reviewed and comments sent to the Developer and their consulting engineer. No wetlands showed up on this property with the recent completion in this area of the wetland inventory. The Enclave g:\....\enclarl.wpd Page 1 of 3 Sanitary Sewer It will be difficult to service the northerly portion of this development unless the structures are slab on grade Existing ground elevations were obtained from a 1991 Dakota County topographical map. Ground elevations range from 956' in the southerly one third of the property, 958' in the middle one third, and 960' in the northerly one third. The best connection to existing sanitary sewer is at a manhole located on Biscayne Avenue approximately 500' north of CSAH 42 with an invert elevation of about 941.0'. The review assumed a sewer line would run northeasterly from this stub out for approximately 2,300' to a point about 150' south of 145th Street West. A manhole about 150' south of 145th Street West would have an estimated invert elevation of 951.0'. The existing ground elevation in this area is 960'. A twelve -foot difference in elevation between the ground and sanitary sewer invert is desirable for typical homes with basements which lead to the conclusion that slab on grade structures would be best suited for the northerly portion of the development. Any septic systems on this property should be abandoned per code prior to any grading on the site Watermain The minimum watermain diameter is 8" for residential property. The watermain in the development will need to be looped between the existing 16" watermain on Biscayne Avenue and a future watermain on 145th Street West. The trunk watermain improvement on 145th Street West is proposed to be constructed with the 145th Street West improvements which are tentatively scheduled for next year. Any wells on this property should be identified and sealed per code. If already sealed, paperwork should be submitted showing proof of closure. Streets The proposed Public Street intersection with Biscayne Avenue needs to align with Bloomfield Path in the proposed Eastbridge Addition. City staff prefers that the street connecting 145th Street West and Biscayne Avenue be a public street. The northerly and westerly cul-de-sac streets are also preferred to be public streets. It is assumed that the Developer would like the remaining streets to be private. If this assumption is incorrect then it will be requested that these streets be constructed to public street requirements. The reconstruction of 145th Street West from Brazil Avenue to County 42 is tentatively scheduled to begin next year. In this development, a maximum driveway width of 12' will be allowed in the public right-of-way per building unit. A maximum driveway width of 24' in the public right-of-way will be allowed if two building units share a driveway. Staff would like to meet with the developer to review driveway locations on the cul-de-sacs, mailbox locations, and new tree locations. Walks & Trails Staff has identified that a 8' wide bituminous trail will be constructed with the 145th Street construction work which is scheduled for next year. Staff has also identified the construction of an 8' trail along the east side of Biscayne Avenue which shall be constructed with other development improvements. A 5' sidewalk is proposed to be constructed along the south side of the proposed public street from Biscayne Avenue to 145th Street. The Enclave g:\....\enclarl .wpd Page 2 of 3 Easements & Right -of -Ways The developer will need to incorporate recommendations made by the Dakota County Plat Commission which are relative to County State Aid Highway 42. Fifty (50') feet of half right-of-way needs to be dedicated for Biscayne Avenue and the proposed trail to be constructed along the east side of this street. Fifty (50') feet of half right-of-way needs to be dedicated for 145th Street. Drainage & Utility easements will need finalizing prior to finalized utility plans. Private Utilities This area will be provided electrical power by Northern States Power, phone service by Frontier Communications, gas service by Peoples Natural Gas, and cable television by Marcus Cable. Street lights will be provided by the developer as determined by the City and Northern States Power. A shoe box style street light will be requested at the public and private street intersections with Biscayne Avenue and 145th Street West besides the normal street light installations. Construction The City has adopted a policy for the public construction of all future publicly owned facilities. The Developer has the choice of City financing or private financing of these improvements per the adopted policy. A petition can be obtained from the Public Works Department. Fees & Assessments Developer must make payment to the City at the time of final plat for the following items: Preliminary payment for future improvements to 145th Street West, including street and trail estimated at this time in the amount of $50,812.80; b. Preliminary payment for future trunk watermain improvements on 145th Street West estimated at this time in the amount of $10,251; 1997 Storm Sewer Trunk Area Charges at $2,530 per acre which is estimated at this time in the amount of $89,056 (Based on 35.2 acres); and d. 1997 Geographic Information System (GIS) fees at $50 per lot/unit estimated at this time in the amount of $6,400 (Based on 128 units). The preliminary payment for future improvements to 145th Street West is based on the 1997 multi -family residential rate of half a street at $53.20 per foot for 804 lineal feet. It also includes $10 per lineal foot for future trail construction on 145th Street West. The preliminary payment for future trunk watermain improvements on 145th Street West is based on the 1997 residential rate of half an 8" watermain at $12.75 per foot for 804 lineal feet.
