Bloomfield Addition Preliminary Plat & Rezoning (Phase 2)CITY OF ROSEMOUNT EXECUTIVE SUMMARY FOR ACTION City Council Meeting Date: June 18, 2001 AGENDA ITEM: Bloomfield Addition Preliminary Plat & Rezoning (Phase 2) AGENDA SECTION: Old Business PREPARED BY: Rick Pearson, City Planner AGEND Property Owner(s): Centex Homes & CMC Heartland Partners LLC ATTACHMENTS: Draft resolution and ordinance, Plan APPROVED BY: Reductions; Carriage Home Elevations; 244 single family and 76 carriage (attached) homes Revised Concept Reduction; PC Minutes, Urban Residential Engineering and Planning memos (5 -8 -01) R -1, Low Density Residential Applicant: Steve Ach of Centex Homes Location: North of CSAH 42 & 145 Street West, and east of Bloomfield's first phase Property Owner(s): Centex Homes & CMC Heartland Partners LLC Area in Acres: 165.51 Number of Lots /units: 244 single family and 76 carriage (attached) homes Comp. Guide Plan Desig: Urban Residential Current Zoning: R -1, Low Density Residential Planning Commission Action: Recommendations of Approval for both the Preliminary Plat and the rezoning. SUMMARY This preliminary plat represents the design of the balance of the former CMC Bloomfield planned unit development as it has been taken over by Centex homes. The design includes streets, lot dimensions, grading, landscaping and utilities. Open space for parkland expansion, storm water ponds and wetlands are also included. .Given the recently requested (and denied) amendment to the PUD, this plan reflects extensive discussions between the City and Developer. The intent and goal of the preliminary plat is to be consistent with the City Council direction and standards. PRELIMINARY PLAT The plans include overall lot & street design, grading, utilities and landscaping which is consistent with the concept approved by Council (minor PUD amendment) on April 3, 2001. The Staff recommended changes will not severely impact the plat, unless right -of -way widths need to be expanded for Bloomfield Path and Auburn Avenue. REZONING All off the property is currently zoned R -1, Low Density Residential. The area containing the 76 carriage homes (Blocks 12 & 13) is part of the approved PUD and should be rezoned as needed to R -2, Moderate Density Residential. PLANNING COMMISSION PUBLIC HEARING No one attended the public hearing other than the Developer and Consultant. The Commissioners expressed concerns about maintenance of open space and ponds. The Commissioners also recommended that more sidewalks be included in addition to the Staff recommendation. DEVELOPER RESPONSE Steve Ach of Centex has agreed to every recommended change with two exceptions: 1. Two of the corner lots (lots 13 and 20, Block 3) will not meet the additional lot width requirement (105 ft.) next to Bloomfield Path, a Collector street. 2. Centex is asking that the Interim City Engineer compromise on right -of -way widths for Collector streets, particularly Auburn Avenue (Street D). Staff has agreed to 70 ROW instead of 80 ft. (local streets are 60 ft.) RECOMMENDED ACTIONS: Motion to adopt a resolution approving the Bloomfield Addition Preliminary Plat for Centex Homes. Motion to adopt an ordinance rezoning Blocks 12 & 13 (Carriage H omes) to R -2, Moderate Density Residential.

CITY HALL 2875 — 145th Street West Rosemount, MN 55068 -4997 Phone: 651- 423 -4411 Hearing Impaired 651- 423 -6219 Fax: 651- 423 -5203 Memorandum To: Honorable Mayor and City Council From: Bret A. Weiss, P. E. Interim City Engineer Re: Bloomfield Preliminary Plat Comments WSB Project No. 1005 -391 Date: May 31, 2001 We have reviewed the preliminary plat submittal dated May 8, 2001, which is a completely revised submittal from the original application. We have attempted to address the major issues with this memo and reserve the right to make additional comments as necessary. Our comments are as follows: Plat Issues 1. The town home lots located north of Bloomfield Path should be platted as individual lots, not combined as shown. 2. Street D should be shown on the plans as Auburn Avenue. 3. The right -of -ways for Bloomfield Path and Auburn Ave should be increased to accommodate a 42' wide street and the proposed pathway /sidewalk sections, including 8 -foot boulevards. 4. The street for Block 13 should be revised to match up with Street B: 5. This plat includes numerous 90° corners, which cannot accommodate the typical 30 mph curves. The City has allowed these in the past, but would prefer to maximize the radii on these types of curves. 6. Street L has less than a 90° corner, which should be revised to a minimum 90° curve. 7. The City is in the process of evaluating the overpass location and the location as shown is subject to modification. C. IwindowslTM -hm-cc. doc 8. All drainage swales must be contained within easements. 9. The eyebrow cul -de -sac in Block 7 should be eliminated. 10. The street widths throughout the plat are shown narrower than the current City standards. The City standards are 32 feet face -to -face for most streets, 28 feet face -to -face for private streets and larger for collector streets. Bloomfield Path and Auburn Ave should be a minimum 42' face -to -face width, as they will serve a collector function. If Bloomfield Path, adjacent to the park is anticipated to include on street parking, the width should be expanded to a minimum 44' width. 11. An expanded easement will be necessary along portions of the MCES sanitary sewer line where the pipe is outside the street. 12. Streets F and L could serve as future minor collectors, depending on how the plats to the east are developed and should be held to the minimum City standard 32' face -to -face width. Grading plan 1. The grading plan should include lot pad elevations and lot types.. 2. The pond in the southeast corner of the site should be self - contained within the site so that it does not spill onto the adjoining site. 3. The erosion control measures and plan should be put on a separate page. The erosion control plan as shown does not currently address the City requirements. 4. The grading plan does not show the proposed sidewalk and pathway locations. 5. The park area should be graded as required by the Parks Department. 6. Provide an earthwork analysis for the proposed grading plan to verify the site balance. All streets shall include only sand sub grade and pathway /sidewalks should include a 1' sand sub base. 7. The large stockpile located north of Bloomfield Path in the Park area should be removed and graded to the Parks Department satisfaction. 8. The proposed berms at the intersection of Auburn Ave and CSAH 42 should be evaluated for site distance issues. 9. The berm along CSAH 42 is lowered from the original grading plan. C- IwindowsITE tOS3101- hm -=doc Sanitary Sewer and Watermain: 1. The plan identifies the installation of a sanitary sewer lift station. We would prefer to utilitize gravity systems if possible. It appears that this can be accomplished by revising the housing styles. Additional justification will be required to justify the proposed lift station. 2. A portion of Block 11 can be connected to the gravity sewer, but is proposed to connect to the proposed lift station. This should be revised. 3. A 16" watermain needs to extend along Bloomfield Path to the east edge of the plat and a 16" watermain will be extended along Auburn Ave from CSAH 42 to the north plat boundary. 4. There are many locations where the watermain dead ends should be looped to another watermain and should be adjusted accordingly. Storm sewer /ponds 1. The proposed storm sewer system is not sized on the plan and does not include invert elevations. The storm sewer design and calculations should be provided for review and elevations on sizes shown on the plan. 2. The future publicly designed storm sewer system will not include catch basin MHs or allow cutting across property lines. 3. Several of the proposed ponding areas do not include the required maintenance bench. 4. The City has made it a practice to avoid rear yard catch basins. This plan has utilized a substantial number of these rear yard catch basins, which should be reevaluated for need. We would prefer to utilize 2% positive drainage swales. Any catch basin that is deemed necessary to remain will need to be analyzed to verify easement requirements. 5. Show the existing storm sewer that discharges into the site from the north. 6. Some adjustments to the pond elevation will be required, however the storage does appear to be in place. Both ponds are very deep and may be in conflict with future City standards with regard to infiltration and oversizing. Please call me at (763) 287 -7190 if you have any questions or comments.

Public Hearing: Bloomfield Addition Prelminary Plat & Rezoning Chairperson Caspar opened the public hearing on the Bloomfield Addition Preliminary Plat & Rezoning. The recording secretary has placed the Affidavit of Mailing and Posting of a Public Hearing Notice and Affidavit of Publication on file with the City. Mr. Pearson reviewed the concept plan for Bloomfield Addition and confirmed that the proposed preliminary plat is consistent with the approved PUD. The preliminary plat pertains to the remaining undeveloped area of the development and includes 255 single family homes, 76 carriage homes, parkland and ponding areas. Staff recommends that Planning Commission Regular Meeting Minutes May 8, 2001 Page 2 the ponding area be maintained by the homeowners' association and that the city retain an easement. Street design and access were reviewed. The consulting City Engineer is reviewing the street widths to ensure that city standards are met. Mr. Pearson noted lot deficiencies due to increased lot depth requirements on collector streets. The developer indicated that any necessary changes would be made to meet those requirements. Proposed access to CSAH 42 requires approval from the Dakota County Plat Commission. Mr. Pearson identified pipeline easements and their effect on individual lots. A 60 foot separation is required between the carriage homes, which the developer indicated will be met. The developer will also make the necessary change to align the intersections for the carriage homes. Sidewalks and trails were reviewed. Mr. Pearson explained the general practice of not placing sidewalks on cul -de -sac streets. Chairperson Caspar suggested that for future developments the city should take a closer look at the lengths of cul -de -sacs in determining whether sidewalks should be required. Commissioners recommended sidewalks on loop streets. Mr. Pearson recommended additional landscaping along CSAH 42 where there are gaps in the berming. Commissioners recommended the addition of conditions to include maintenance of the ponding areas and additional sidewalks. Chairperson Caspar opened the floor to the public. There were no comments. Dwight Jelle, Construction Engineer for the project, provided a history of the development and assured Commissioners that city regulations would be met. As concerns the ponding area, Mr. Jelle indicated a preference to run an imaginary line through the middle of the pond, extending lot lines from the single family homes and requiring the homeowners' association to maintain the other half of the pond. Ponding capacity was discussed. Mr. Jelle wishes to clarify with the city whether there is any off - site drainage into the pond. MOTION by Carr to close the public hearing. Seconded by Napper.

TO: Planning Commission FROM: Rick Pearson, City Planner DATE: May 3, 2001 RE: Bloomfield Addition Preliminary Plat Comments CITY HALL 2875 — 145th Street West Rosemount, MN 55068 -4997 Phone: 651 - 423.4411 Hearing Impaired 651 -423 -6219 Fax: 651 -423 -5203 BACKGROUND This preliminary plat is a new application that is based upon the original Bloomfield Planned Unit Development as it has been amended and approved by the City Council. It should not be confused with the previous PUD major amendment that was denied by the Council. Subsequently, Centex Homes, (the applicant) prepared a concept drawing that was consistent with the originally approved CMC Heartland Partners concept. The new concept reflected the Centex approach to development and did not require a public hearing because the revisions were quite minor. The Council did approve the Centex concept. PRELIMINARY PLAT The plan is dominated by 244 units of single family housing on approximately 70% of the land. The 76 Carriage home units occupy about 7.5 %, with the balance given over to park expansion (5 acres) and ponds /wetlands (12.85 acres). ACCESS & STREET DESIGN Three streets are the primary entrances into the development. "Street D ", a collector street connects to CSAH 42, and has been named Auburn Avenue. This is a through street that will connect to an extension of Connemara Trail (Street K ") as it eventually crosses the railroad tracks from the north. Bloomfield Path is a collector street that is an extension from the first phase. All three streets will not have any direct driveway access. All driveways will connect to local streets that will connect to these three "through streets ". Two of the local streets connect to the vacant land to the east to promote neighborhood "interconnectedness ". The Interim City Engineer has commented that the street design and right -of -way widths will be required to conform to city standards. The plans indicate several street width and design issues that will have to be revised, or the Council will have to approve them as exceptions. "Street D" (Auburn Avenue) is notable as a collector street which will be recommended for addition right -of -way and street width. "Street K" (Connemara Trail) is located in the position that has been previously recommended by the City. Ther may be "fine- tuning" of the location and width. The railroad crossing is intended to be grade May 8, 2001 PC Reviews - Bloomfield Preliminary Plat & Rezoning Page 2. separated. For this reason, the adjacent lots are deeper in order to absorb some of the anticipated grade change for a bridge approach. The half -loop street for the three carriage home buildings that connects to the north side of Bloomfield Path should line up with "Street B" at both ends. The reason is to eliminate off -set intersections with very small intervals between them. LOT ISSUES The plat design typically provides for additional lot depth along the outer edges of the development, especially for the screening needed to mitigate the effects of the highway and the railroad tracks. Recent Council direction indicates strict adherence to R -1 Low Density lot standards for single familyOut of 244 lots, Staff has identified 12 lot dimension variances. Lot & Block Scaled Dimension Standard Variance Lot 20, Block 3 95 feet width 105 feet width 10 feet Lot 13, Block 3 90 ft. width 105 ft. width 15 ft. Lot 33, Block 1 113 ft. depth 125 ft. depth 12 ft. Lot 41, Block 1 97 ft. width 105 ft. width 8 ft. Lot 28, Block 4 91 ft. width 105 ft. width 14 ft. Lot 29, Block 4 98 ft. width 105 ft. width 7 ft.

Lot 8, Block 7 132 ft. depth 135 ft. depth 3 ft. Lot 1, Block 7 100 ft. width 105 ft. width* 5 ft. * This section of "Street D" may not have to be a collector street, which reduces the lot dimension requirements. Most of the variances occur on lots that are adjacent to collector streets which have requirements for increased lot dimensions for screening. Several lots are affected by pipeline or sewer easements. Specifically, Lots 12, 13 and 14 Block 8; and Lot 1, Block 7 are situated along a natural gas easement. The pipeline company that controls the easement will have to be willing to allow driveways across the easement. All of the lots have enough space beyond the easement area to allow houses elsewhere on the lot. Likewise, several lots and streets are located on top of the Metropolitan Council sanitary sewer interceptor easement. Obviously, cooperation and approval is also needed. All of the lots affected have space outside of the easement for house pads. May 8, 2001 PC Reviews — Bloomfield Preliminary Plat Page 3. CARRIAGE HOMES The 75 units distributed over 19 "quad" buildings are shown in the place of the CMC "Mansion homes ". Since CMC is out of the picture, the carriage homes are an acceptable substitute. They are required to be consistent with the attached housing standards in the zoning ordinance. The attached elevations /plans were included in the previous PUD Amendment package. The units will have to be platted on separate lots, or as a condominium development for sale of individual units. PARKS, SIDEWALKS & OPENSPACE Outlot A consisting of about 5 acres is proposed for park expansion. Previously, the Parks and Recreation Commission did make a recommendation to the City Council regarding additional park dedication in this area. This preliminary plat will require follow -up to that previous recommendation. Outlot B is set aside for ponding and wetlands. There may be an opportunity to locate a trail on one edge, but this item will be included in the P & R Commission recommendation. Sidewalks were not indicated on the preliminary plat drawings. Therefore the staff recommendation is as follows: 1. Sidewalks on one side and trail or sidewalk on the other side of Bloomfield Path; "Street D" (Auburn Avenue) and "Street K" (Connemara Trail), and "Street C ". 2. Sidewalks on one side of Azalea Path; "Street A "; "Street B "; Bayberry Trail (Except the cul -de -sac); "Street E "; "Street F "; "Street J" and "Street D "(north of Connemara Trail /Street K). LANDSCAPING The landscaping plan meets minimum requirements for boulevard trees (1 per lot/unit frontage) and screening along the railroad tracks. 6ft. berms have or will be graded along CSAH 42. The landscaping along CSAH 42 does not provide a complete screen. However, the berm fulfills the function. Gaps in the berm along CSAH 42 point to a need for extensive landscape screening in these areas, particularly east of "Street D" (Auburn Avenue). RECOMMENDATION Motion to recommend that the City Council approve the Bloomfield Addition preliminary plat for Centex Homes subject to: 1. Conformance with requirements for final plat for each phase and execution of a subdivision agreement with each final plat. 2. Plan revisions as necessary to eliminate the 12 lot dimension variances identified by staff. May 8, 2001 PC Reviews - Bloomfield Preliminary Plat Page 4. 3. Plan revisions as necessary to incorporate recommendations by the Interim City Engineer relative to easements, grading, street design, rights -of -way and utilities. 4. Approval of the Dakota County Plat Commission in accordance with the contiguous plat ordinance. 5. Approvals as needed from applicable agencies and pipeline companies for public and private use of easement areas'. 6. Park dedication in a form as recommended by the Parks and Recreation Commission. 7. Sidewalks & Trails installed by the Developer as identified by Staff. 8. Enhancement of Landscaping along CSAH 42 within areas not screened by 6' high (along rear yards) berms.
