Box 510, Rosemount, Minnesota 55068.0510 TO: Mayor McMenomy Council Members Klassen, Staats, Willcox, Wippermann FROM: Stephan Jilk, City Administrator DATE: January 31, 1992 RE: Legislative Position Statements Legislative Breakfast MAYOR Edward S. McMenomy COUNCILMEMSERS Sheila Klassen James (Red) Steals Harry Willcox Dennis Wippermann ADMINISTRATOR Stephan Jilk On January 21st the City Council passed a motion to support the legislative position statements drafted by the Dakota County City/County Administrators. On January 30th the City Administrators met to discuss any changes proposed by the various city councils and the County Board during their consideration of the position statements. There were several changes I wish to bring to your attention so that if you have concerns with them we can consider them before we present them to the legislative delegation. The following changes were considered and consensus was reached: 1) Drug Education and Enforcement The last paragraph relating to the county's levy will be separated out as a separate recommendation. 2) Local Government Finance - In the background section thesecond paragraph was revised to replace the words "has further diminished the ability of" with "prevents". In the recommendation section the Levy Limits section was discussed in depth. The County is not supportive of removing levy limits because they are concerned that if levy limits are removed the state will mandate additional programs, now funded and managed by the state, to be funded and managed by the county. Consensus was that if the cities and the county can agree on some language which addresses this concern the levy limit section will be left in. If a compromise can't be reached the levy limit section will be removed. 3) Regional Airport Policy - In the recommendation section the #1 recommendation was revised by removing the last sentence. In addition there will be an additional recommendation to indicate that we should not allow any transportation dollars to be allocated away from other needs to fund planning and/or construction of any needed elements of the relocation of a new airport. 6vertylhtngs (Pouring ` J6 RosemounlY `i ecvc�eA Wane., 4 • The revised draft of the position statements will not be available for a few days and I wanted to get you this information for our meeting. Legislative Breakfast - The planned breakfast at which we will present these issues is planned for February 14th at 7:30 a.m. at the Rosemount American Legion. At this time at least six of the legislators from Dakota County have committed to attending. I would encourage all of you to attend and exhibit support for the legislators consideration on these issues.

The project area is located in the northwest quarter of the southwest quarter of Section 31 and lies immediately north of West Ridge 3rd Addition and south of Wensman 3rd and 4th Additions. The westerly boundary of the plat is located on the Apple Valley corporate limits. 2.2 Project Area West Ridge 4th Addition consists of 32 single family residential lots, an outlot for future construction of County Road 33 (Diamond Path), and rights-of-way for seg- ments of Darling Path, 156th Street West, and Darjeeling Path. This is the fourth phase of the Rosemount West PUD. 2.3 Adjacent Property The project area is adjacent to West Ridge 3rd Addition and Wensman 3rd and 4th Additions. Utility and street construction in West Ridge 3rd Addition was com- pleted in 1990 under City Project No. 195, Contract No. 1989-2. Utility and street construction in Wensman 3rd Addition was completed in 1989 under Project No. 510. Utility and street construction in Wensman 4th Addition was completed in 1990 under Project No. 512. Outlot A, located on the west end of the plat, has been reserved for the future con- struction of County Road No. 33 (Diamond Path), and will be dedicated to the City for this purpose. It is anticipated that a future phase of the West Ridge Development will be located immediately to the east of the project area. 2.4 Site Conditions The project area is currently used for agricultural purposes. In accordance with City requirements, all street and site grading will be completed by the developer in accordance with the master grading plan submitted in the approved PUD. The required street grading includes core excavation of all plastic (non -suitable) mate- rials within the roadway area and replacement with granular (suitable) materials. Part 2 General Background Page 3 Part 3 Proposed Improvements 3.1 Sanitary Sewer Proposed sanitary sewer facilities are shown in Drawing No. 2. These facilities include the northerly extension of a 10 inch trunk sewer along Darling Path from the inplace stub south of 156th Street to the inplace stub in Darjeeling Path; the con- struction of an 8 inch sewer along 156th Street east of Darling Path; and the con- struction of an 8 inch sewer along Darling Path east of Darjeeling Path. The 10 inch connection along Darling Path will result in the abandonment of the private lift station and forcemain currently serving Wensman 3rd, 4th and 5th Additions. The developer of Wensman Additions will be responsible for removing the temporary lift station and abandoning the 4 inch forcemain. The extra depth 10 inch trunk sewer will also allow for future development to the north of Wensman 5th Addition. The 8 inch sewer on Darling Path east of Darjeeling Path and on 156th Street will provide for future easterly extensions to serve a subsequent phase of the West Ridge Development. The proposed facilities also include the installation of 4 inch services 15 feet into each lot from the proposed mains in the street. Service risers will be installed on the extra depth 10 inch main. 3.2 Watermain Proposed watermain facilities are shown in Drawing No. 3. These facilities include the northerly extension of an 8 inch main along Darling Path from the inplace stub south of 156th Street to the inplace stub in Darjeeling Path; the extension of an 8 inch main along 156th Street east of Darling Path; and the construction of a 6 inch main along Darling Path east of Darjeeling Path. Future extensions to, the east will be made from the mains along 156th Street and Darling Path east of Darjeeling Path to serve a subsequent phase of the West Ridge Development. The proposed facilities will also include the extensions of 1 inch services 15 feet into each lot from the proposed mains. 0 Part 3 Proposed Improvements Page 4 LJ 3.3 Drainage Proposed drainage facilities within the project are shown in Drawing No. 4. These facilities include the northerly extension of a 21 inch trunk storm sewer along Dar- ling Path from the inplace stub south of 156th Street to the inplace stub near the northeast corner of Outlot A; and the construction of a 15 inch main from the trunk main in Darling Path into Block 3 to facilitate back yard drainage. Inlets are pro- posed along Darling Path and at the intersection of Darling Path and 156th Street West. The proposed 21 inch storm sewer connection will provide an overflow from the Wensman 4th Addition pond to the West Ridge pond located adjacent to Shannon Parkway and 160th Street. This overflow is consistent with the City of Rosemount Drainage Plan for the West Drainage Area. It may be possible to eliminate back yard drainage facilities during the final design stage if significant changes are made to the developer's proposed grading plan. If these drainage facilities are installed, emergency overflow routes will be provided to prevent back yard flooding. 3.4 Street Construction The construction of standard City streets is proposed as shown in Drawing No. 5. The proposed streets are 30 feet wide between curb faces and are located within 60 foot rights-of-way. The proposed street section consists of a 1-1 /2 inch bituminous wearing course and 1-1/2 inch bituminous binder course placed over a 6 inch aggregate base with design D418 (surmountable) concrete curb and gutter. This pavement section assumes that a granular subgrade will be provided by the devel- oper. Rough grading, topsoiling and seeding of the boulevards will also be included in the City's contract. However, the developer will be responsible for final restoration of the boulevard areas as a part of the final lot development. ! The street facilities will also include the construction of 6 foot wide concrete side- walks along the south side of 156th Street West, the east and south sides of Darling Path, and the west side of Darjeeling Path. Temporary bituminous cul-de-sacs will be constructed on the easterly ends of Dar- ling Path and 156th Street West to facilitate emergency vehicle access. Part 3 Proposed Improvements Page 5 0 6 IM 0 3.5 Lighting The street lighting system within West Ridge 4th Addition will be provided by the local electric utility (Dakota Electric Association) as a part of the extension of ser- vice into the project area. Provisions for electric service and associated restoration should be coordinated by the developer. Installation of the system should not occur until the street construction is completed. 3.6 Easements A 15 foot utility easement will be required along either side of the common lot line between Lots 6 and 7 of Block 1, and Lots 1 and 13 of Block 3 for the installation of proposed storm sewer facilities. A 15 foot utility easement will also be required along the back line of Lot 7, Block 1 for the proposed trunk storm sewer. Part 3 Proposed Improvements Page 6 Part 4 Financing 4.1 Cost Estimates Detailed cost estimates for all proposed improvements are included in the Appen- dix of this report. These estimates are based on projected 1992 unit costs and include allowances for contingencies (10%) and anticipated overhead costs (30%). These estimates do not include any costs for street or site grading, or for easements which will be required of the developer as a part of the Development Contract with the City. A summary of these costs is as follows: Sanitary Sewer $113,000 Watermain 71,000 Storm Sewer 60,000 Street Construction 121,000 Total $365,000 4.2 Assessment Area The following parcels of land are located within the project area and are subject to assessments to recover the project costs. ! West Ridge 4th Addition Block 1, Lots 1 through 11 Block 2, Lot 1 Block 3, Lots 1 through 13 Block 4, Lots 1 through 7 4.3 Cost Recovery 4.3.1 Core Facilities A core facility cost has been defined as the difference in cost between the actual improvement and a residential equivalent improvement. For trunk sanitary sewer, the cost of the extra depth and pipe diameter of mains in excess of 8 inches is considered to be a City core facility cost. For trunk storm sewer, the cost of the extra depth and pipe diameter which is in excess of that needed to serve the immediate site is considered to be a City core facil- Part 4 Financing Page 7 0 i 0 Part 4 Financing Page 8 ity cost. The above core costs are not assessable to the project area, but can be recovered from the respective Core Facility Funds. The sanitary sewer and storm sewer core cost calculations are included in the Appendix of this report. With standard contingencies and overhead allowances, the estimated core costs are as follows: Sanitary Sewer Core Cost $48,000 Storm Sewer Core Cost 16,000 4.3.2 Assessments After the core facility costs have been subtracted from the total estimated cost of the project, the remaining assessable amount is $301,000. Spreading this amount over the 32 lots in the project area, the total esti- mated assessment rate for each lot is $9,400. 4.3.1 Summary Assessments = $301,000 Sanitary Sewer Core Facility Costs = 48,000 Storm Sewer Core Facility Costs = 16,000 Total $365,000 0 i 0 Part 4 Financing Page 8 0 • 0 0 Part 5 Project Schedule Page 9 Part 5 Project Schedule The proposed schedule for this improvement is listed below.

This report addresses the sanitary sewer, watermain, storm drain and street necessary for the area. We would be happy to discuss this report with you at your convenience. Please call if you have any questions. Respectfully, ORR-SCHELEN-MAYERON & ASSOCIATES, INC. Bud Osmundson, P.E. Associate /cmw 0127hm&c Enclosure EXECU'!'[VE S. City Project No. 225 provides for the installation of city utilites and streets in the Third Phase of the Shannon Hills Planned Unit Development in western Rosemount. The project includes the installation of sanitary sewer, watermaut, storm drain, and street lighting` facilities plus the construction of the streets and a sidewalk within the Third Addition. The grading of the area will be completed by the developer under a private contract. The impetus for the project was a petition from the developer, Ground Development. The project is feasible from an engineering standpoint. This Feasibility Report proposes the construction of approximately 1,660 lineal feet of sanitary sewer, 1,750 feet of watermain, 1,490 feet of storm drain, and 1,750 feet of street construction to provide service to 26 residential lots. The total estimated project cost is $344,400. The funding for the project will totally come from assessments to the benefitted property. The project construction can be initiated in May, 1992 with construction substantially complete in June, 1992. 1.0 1.1 1.2 1.3 RODUCTI4N Authorization - On January 7, 1992, the Rosemount City Council authorized the preparation of an Engineering Feasibility Report for Public Utilities and Street Construction for the Shannon Hills Third Addition. This project has been designated as City Project No. 225. The Developer submitted a petition for these improvements, which constituted 1100% of the benefitted property. Scope This project provides for the construction of utilities and streets in the Shannon Hills Third Addition in western Rosemount. Sanitary sewer, watermain, storm drain, street, sidewalk, and street light facilities will be provided to the Third Addition. The Developer, Ground Development, is responsible for the site grading in the Third Addition, which will be competed prior to the construction of the utilities and street examined in this report. Data Available - Information and materials used in the preparation of this report include: ♦ City of Rosemount Record Plans. ♦ Comprehensive Water System Pian, October, 1988. Comprehensive Storm Water Drainage Plan, West Drainage Area, May, 1989 ♦ Shannon Hills PUD Preliminalry Plat and Preliminary Grading Plan. ♦ Construction Plans from the Shannon Hills Second Addition, City Project No. 216. 1 2.0 GENERAL BACKGROUND 2.1 Location - The project is located in the southwest quarter of the northeast quarter of Section 30, adjacent to and west of the Carrollton Addition, and adjacent to and north of Shannon Hills First and Second Additions. The project location is shown on the Location Map, Drawing No. 1, at the end of this report. 2.2 Project Area - The Shannon Hills Third Addition consists of 26 single-family residential lots, plus dedicated street right-of-way and an outlot. The Shannon Hills Planned Unit Development consists of 75 acres of single-family residential lots. The Shannon Hills First and Second Additions are immediately south of the Third Addition. The Second Addition was constructed in 1991 and provides utility access for the Third Addition. The project area is currently zoned R-1. 2.3 Existing Conditions - The project area is currently used for agricultural purposes.The terrain is primarily rolling grassland. The area generally slopes and drains from the north to the southwest to a wooded ponding area. 2 3.0 PROPOSED IMPROVEMENTS 3.1 Sanitary Sewer - The proposed project will provide sanitary sewer service to the Shannon Hills Third Addition, plus extensions to the future Shannon Hills Additions to the north. The proposed 8" PVC gravity dines will generally flow from the west to the east, then south to the existing extension provided in the Shannon Hills Second Addition. Four inch services will be provided to the lots within the Third Addition. The proposed sanitary sewer facilities are shown on Drawing No. 2. 3.2 Watermain - The proposed watermain facilities are shown on Drawing No. 3. The proposed project will provide water service to the 'Third Addition, plus extensions to the future Shannon Hills Additions to the north. A 6 watermain will be extended to the east on proposed 143rd Street West from an existing b" hydrant lead located on Shannon Parkway. An 8" watermain will be extended north from an existing extension in the Second Addition within Cobler Avenue. A 6" watermain will also be provided on the proposed cul-de-sac, Crofton Court. The proposed facilities include 1" services to each of the lots. Hydrants will be spaced accordingly for a residential area. 3.3 Storm Drain - The proposed storm drain facilities are shown on Drawing No. 4. The proposed storm drain facilities will generally drain the proposed subdivision from east to west to a detention pond near Shannon Parkway. The proposed piping ranges in size from 12" to 24" diameter. An overland overflow drainage swale is necessary between Lots 6 and 7, Block 2, at the low point on 143rd Street West, which shall be completed under the grading contract. The outlet for the detention pond was constructed in the Shannon Hills First Addition Project. In accordance with the City policy, all storm drain facilities are sized to transport runoff from a 10 year storm event and all ponding areas and outlet sewers are sized for a 100 year storm event. 3.4 Street Construction - The proposed str proposed streets will be constructed to street. The street section will consist of 3 :s are shown on Drawing No. 5. The ty standards which call for a 3T wide of bituminous courses and 6" of Class' 5 Aggregate Base, based on the soils information known at this time. The street will be flanked by surmountable concrete curb and gutter. The street section design and cost estimate are based on the assumption that an acceptable subgrade is provided by the grading operation, for which the Developer is responsible. A small amount of sodding and seeding blanket are provided in this project for erosion control. 3.5 Sidewalk - An 5' wide concrete walk isproposed to be constructed within the Shannon Hills Third Addition along the south side of 143rd Street and along the east side of Cobbler Avenue for approximately 1,460 L.F. This trail will ultimately connect Carrolls Woods Park with the Shannon Parkway Trail. 3.6 Street Lighting - The proposed lighting units are the Type "A" units which are 15 feet high poles ' with post top mounted fixtures. The feed points and connector runs will also be installed. The local electric utility in this project area is Northern States Power Company, which will install all of the electric utilities for this project under a separate contract with the developer. 3.7 Permits - Permits will be required for this project from the Minnesota Department of Health for watermain extensions and the Minnesota Pollution Control Agency for sanitary sewer extensions. Approval of the sanitary sewer plans is also required by the Metropolitan Waste Control Commission. 3.8 Right-of-Way and Easements The 60' right-of-way and all necessary easements are anticipated to be dedicated by the Developer on the final plat. The majority of the facilities are located within the'; right-of-way except the storm drain facilities north and south of Crofton Court. These facilities will require 20' wide easements centered on the common lot lines between Lots 5 and 6 of Block 1, and Lots 9 and 10 of Block 2. In addition, a ponding and drainage utility easement will be required in the rear yard areas of Lots 9 through 13 of Block 2. FINANCING 4.1 Cost Estimate - A detailed Cost Estimates can be found in the Appendix. The following estimates are based on 1991 construction costs and include a 10% contingency factor and all related administrative costs. The administrative costs are estimated at 30% and include leg al, engineering, interest, and other administration. A summary of these costs are as follows: 4.2 A.
