Home My WebLink About10B - CR 21 Extension Layout MEETING DATE: AGENDA #: PREPARED BY: AGENDA ITEM: DISCUSSION: ISSUES: CITY COUNCIL AGENDA REPORT DECEMBER 1, 2008 10B STEVE ALBRECHT, DIRECTOR OF PUBLIC WORKS CONSIDER APPROVAL OF A RESOLUTION APPROVING THE CR 21 EXTENSION LAYOUT Introduction The purpose of this agenda item is for the City Council to consider approval of the layout for the CR 21 extension from CR 42 to the northern city limits. Historv The City of Prior Lake has supported the CR 21 Extension Project as part of the City's Transportation Plan. The project layout has been developed based on City of Prior Lake comments related to an Environmental Impact Study approved in 2005 and a utility extension and underpass study approval on June 2, 2008. The County has begun final plan preparation for the CR 21 extension project, which must be initiated by 2010 or significant federal funding will be lost, and needs City approval on design elements related to the City. These elements include intersection locations, lighting and trail connections. Current Circumstances The attached exhibit shows the proposed project layout. The following elements are included in the design: 1) Future City intersection with North Berens Road which will extend west to Shepards Path Campus and east to Pike Lake Park in the future. 2) Bituminous Trails on both sides of CR 21. 3) Pedestrian Street lights (downtown style) on the east side of CR 21 from CR 42 to North Berens Road. A copy of the Transit Station Layout in Shakopee has been included for information purposes only. The Transit Station approvals will be completed as part of the Transit Agreement approval expected in January or February of 2009. As the Council is aware once the CR 21 extension is completed, traffic volumes in this area are expected to triple on CR 21 by 2030. Volumes on CR 42 near CR 21 are expected to nearly double. These increases will make pedestrian crossings at the CR 21 and CR 42 intersections increasingly difficult. This intersection will be a primary corridor for pedestrians utilizing Pike Lake Park, Jeffers Pond Park, Jeffers Pond Development, Shepherd's Path Campus and the future Vierling Property development. :-?sporls\1 www.cityofpnorlake.com .:::: Phone 952.447.9800 / Fax 952.447.4245 For that reason the City worked with WSB Associates to develop alternatives for pedestrian traffic in the CR 42/ CR 21 area. The following alternatives were identified (see attached graphic): Option 1: CR 21 Overpass Advantages/Disadvantages Provides Safe Crossing High Construction Cost Not desirable location Provides safe crossing Promotes connectivity between YMCA/Shepherd's Path and future park Cost effective Only feasible crossing option north of CR 42 Not at CR 42/CR21 Intersection East side can only be partially constructed until development occurs Provides safe crossing under CR 42 west of CR21 Not feasible due to water levels of ponds and outlet channel Provides safe crossing Good location Costs of constructing prior to development and CR 21 intersection reconstruction is cost prohibitive Provides safe crossing Good location Costs of constructing prior to development and CR 21 intersection reconstruction is cost prohibitive Provides safe crossing Combines options 4 and 5 to provide pedestrian mobility from east to west and north and south of CR 42 and CR 21 Cost savings achieved by combining Pedestrian access to NW quadrant will still need to be via intersection at grade crossings Costs of constructing prior to development and CR 21 intersection reconstruction is cost prohibitive 2: CR 21/ North Berens Underpass 3: CR 42 Underpass West of CR 21 4: CR 21 Underpass South of CR 42 5: CR 42 Underpass east of CR 21 6: Options 4 and 5 combined Cost $2,650,000 $330,000 Not Feasible $956,500 $948,500 $1,500,000 All of the options considered meet ADA requirements. Based on the results City Staff believes the Council should consider three scenarios: A) Utilize stoplight controlled intersections for pedestrian crossings and construct no underpass facilities. B) Plan for Option NO.6. Completion would need to be timed with the reconstruction of the CR 21 and CR42 intersection and development of the adjoining properties. The City does not have funding available to complete this option as part of the CR 21 extension project. The City has approximately $300,000 available with the CR 21 intersection for pedestrian improvements. By waiting the total costs can be reduced by 50%, however it could be 20 years before the intersection is reconstructed. CONCLUSION: FINANCIAL IMPACT: ALTERNATIVES: C) Plan for completion of option 6 but construct option 2 as part of the project. This option provides the City with an east west connection as soon as the Berens Road construction is completed with adjacent development. Option 6 alone does not allow for pedestrian mobility to the NW quadrant which includes the Shepherd's Path Campus. Historically, pedestrian crossing facilities have not been planned to address future roadway traffic volumes. The Council needs to determine which if any options should be pursued. The Council needs to provide staff with direction with regards to the proposed design and pedestrian facilities. The City Council will review final design details and estimated costs as part of the final plan and cooperative agreement approval scheduled for February of 2009. The Council also needs to provide direction regarding pedestrian crossing facilities. If pedestrian crossing facilities are desired, staff believes that scenario C which includes construction of option 2 and planning for option 6 is the best long term for the City. The project layout is consistent with cost estimates included in the City's 10 Year Transportation Plan which estimated $975,000 for the City's cost. Final costs and payment timing will be determined as part of the Cooperative Agreement. 1. Approve a resolution approving the layout with any City Council modifications. 2. Deny this agenda item for a specific reason and provide staff with direction. 3. Table this item to a certain date in the future Staff recommends alternative number 1.
