AUGUST 7,1995 AGENDA #: PREPARED BY: SUBJECT: INTRODUCTION: The purpose of this Agenda item is to discuss and approve the concept plans for the improvement of CSAH 21 and CSAH 42, approve the preparation of the feasibility report and authorize the city's engineering consultant MSA to prepare the feasibility report. The purpose of the feasibility report is to determine the costs for trunk sewer and water lines. BACKGROUND: The proposed improvement for CSAH 21, located between County Road 82 and CSAH 4:2, upgrades the existing road from a two lane rural design to a four lane urban design. As an urban design, the improvement will include curb and gutter and a concrete median. Other improvements include a bikeway, which will be constructed the length of the project on the east side and a traffic signal, which will be installed at the intersection of County Road 82 and CSAH 42. Trunk watermain will be installed with the project and improvements will be made to the storm sewer and ponding system. Limited landscaping will be included where houses do not have a buffer. A median will be constructed with channelization from CSAH 42 to the south side of lords Street. The median will provide channelization for turn lanes. Channelization will be included at three intersections for future access to the Jeffers parcels. Those intersections are Carriage Hills Parkway, Coachman lane and Raspberry Ridge Road. 16200 Eagle Creek Ave., Prior Lake, Minnesota 55372-1714 / Ph.

As a rural design, the road will be divided by a grass median. An eight foot bituminous bikeway will be constructed from CSAH 21 to Ferndale Avenue along the south side. Trunk watermain and sanitary sewer will be installed with the project and improvements made to the storm sewer and ponding system. Because of the rural character of the area, landscaping will not be included with this project. The rural design will provide channelization with turn lanes for the existing street intersections on CSAH 42. Full access with turn lanes and a median opening will be provided on CSAH 42 at Ferndale Avenue, Rolling Oaks Circle, Pike Lake Trail, CSAH 21, and McKenna Road. Individual driveways will have limited access to right in, right out. Future access points to the Vierling parcel to the north will be determined when development occurs. This parcel is not in the urban service area and is in the Agricultural Preserve Program. Scott County would like to construct CSAH 21 and CSAH 42 in 1997. The county would like to construct the two projects concurrently to balance out the earthwork. CSAH 42 has an excess amount of dirt which will be used on CSAH 21 which is short of dirt. The county intends for the CSAH 18 project to begin in 1996 but is facing a potential lawsuit from residents in the Shakopee portion of the project. The previous lawsuit by these same residents, based on a noise variance, was disallowed when the State legislature conditionally exempted county roads from the requirement for a noise variance. If the project is delayed by legal action, the county intends to move the CSAH 42 and 21 projects to 1996 and construct CSAH 18 in 1997. The county will make that assessment at the end of this year. The city can not fund 2 , "'.. _ . ...,......-.--_.~~_~".<.".,"'~~"v,.,~_.""H__.'~~"-_~n'u'.~........_.."~ both projects in 1996, but can in 1997. By doing both projects in 1997, the city can use two separate bond issues, (one each year) to fund the city's share of the costs. Funding of these projects has a substantial financial impact on the city. Staff has proposed reducing the scope of the projects to reduce the City's Ad Valorem Tax Levy. The County Road 42 project is proposed as a rural section versus urban section to reduce cost. The trail is proposed to be on one side (south side) from Ferndale Avenue to CSAH 42. No landscaping is proposed as the area is either agricultural or the existing residential areas currently have a buffer. Trunk sanitary sewer and watermain improvements need to be included. On CSAH 21 the proposed improvements are a bikeway on the east side only to reduce cost. The landscaping would be limited to residential areas which do not have an existing wooded buffer. Trunk watermain improvements need to be made. Staff is requesting that MSA prepare a feasibility study to more accurately determine costs for the trunk sewer and watermain improvements. Staff is also reviewing the proposed comprehensive sewer and water plans for their consistencies. The following is an estimated cost summary for CSAH 21 and 42. The requested feasibility study will refine the cost of the utilities. CSAH 21 Storm Sewer Bikeway Curb and Gutter Signal System Landscaping Total city cost Project levy County project total = $ 330,000 = $ 105,000 = $ 62,000 = $ 12,000 = $ 33,000 = $ 542,000 = $ 542,000 = $3,755,000 3 Funding for CSAH 21 will be by project levy and is estimated to be $542,000. CSAH 42 Storm Sewer Curb and Gutter 16" Watermain 12" Sanitary Sewer Relocation 1 0" Sanitary Sewer Bikeway Total city costs Trunk Reserve Project levy County Project Total = $ 30,000 = $ 2,500 = $ 173,000 = $ 45,500 = $ 71,500 = $ 260,000 = $ 582,500 = $ 290,000 = $ 292,500 = $3,065,000 Funding for CSAH 42 will be by project levy and trunk reserve. The estimated project levy is $292,500 and the Trunk Reserve expenditure is $290,000. The 12" sanitary sewer indicated above may be relocated if the county needs to correct for bad soils in the area near McKenna Road. The 10" line will serve the Meadowlawn and Rolling Oaks Circle area to the south of CSAH 42. The county is proceeding with the design of the projects, and would like Council approval of the design concepts. Final plans will be presented to the City Council in the future. The city and county have had neighborhood meetings with adjacent property owners previously. Property owners will receive a notice of the meetings. Plans are available in the Engineering Department. A frontage road was requested by the four property owners north of CSAH 42 east of CSAH 21 to provide access. This request was made at the informational meeting. Staff explained that the cost of the frontage road could not be justified. 4 The City asked MSA Consulting engineers to submit a proposal with a cost estimate to prepare a feasibility report for CSAH 21 and CSAH 42. The cost of the feasibility study is $5,000. Funding would be from the Trunk Reserve Fund. ALTERNATIVES: The alternatives are as follows: 1. Make a motion and second to approve the concept plans for CSAH 21 and CSAH 42, and authorize MSA Consulting Engineers to prepare a feasibility study for CSAH 21 and CSAH 42 utilities. 2. Make a motion and second to disapprove the concept plans for CSAH 21 and CSAH 42 3. Table this item for specific reasons. RECOMMENDATION: The recommendation is to approve Alternative No.1. FINANCIAL IMPACT: The project will be funded by project levy and trunk reserve. ACTION REQUIRED: Make a motion to approve or deny the concept plans, the feasibility report and a orization for MSA to prepare the report at a cos t to eed $5,000.
