Presently,the City of OPH is interested in preliminary cost estimates,related to the potential provision of municipal infrastructure and services(roadway,sewer,water and storm water),related to approximately 35 acres of the 5o acres located in Stillwater Township as shown on the attached figure. Public infrastructure was planned in OPH's current Comprehensive Plan to potentially serve this area. The Feasibility Report will outline a study and present costs and financing alternatives to serve the 35 acres with public infrastructure to allow development to occur and will include the following: • Roadway Improvements/Extension of 58th Street Westerly: The study will present up to two alternatives with associated estimated costs to extend 58th Street to the west from Memorial Avenue as a Minor Collector to Manning Avenue.Manning Avenue presently exists as a two lane rural road serving existing development in the City of Lake Elmo and Stillwater Township connecting to Hwy 36.This section of Manning Avenue is the only access to these existing developments.Manning Avenue at Hwy 36 has a fully signalized intersection. • Sanitary Sewer and Water Service: Sanitary sewer and water main would be extended from Memorial Avenue. Alignments anticipated and estimated costs to serve this area in the City's comprehensive utility plans would be confirmed and refined as necessary. • Storm Water/Natural Resource Plans:Storm water from the study area naturally drains north under Hwy 36 to Long Lake in the City of Stillwater. This area is included in Browns Creek Watershed District.OPH's Comprehensive Storm Sewer Plan identifies ponding and storm sewers to serve this area when it develops. Cost estimates for stormwater improvements for the proposed infrastructure will be provided and potential land acquisition areas will be quantified.The existing wooded areas included in the study area will be identified and the report will include preliminary Storm Water and Natural Resource Plans that will delineate open spaces that satisfy the goals of the City and Watershed District for this area as it develops. • Land UseLGrading Alternatives:The potential alignment of 58th Street in relation to Manning Avenue is dependent on future land use and the preferred location of the potential roadway in relation to the existing transmission towers/power lines and visibility to Hwy 36. The extent that grading is needed beyond the required right of way for 58th Street will be dependent on its preferred vertical and horizontal alignments,which in turn,will have direct impacts on the costs to construct the roadway.The attached Site Map shows the existing transmission towers/power lines,woodlands,contours,and wetlands.The anticipated land use in OPH Comprehensive Plan for this area is Business/Residential Transition. Meetings with City Staff are included to review alternatives for consideration. 1 Feasibility Report Estimate Potential Stillwater Township Annexation Area Oak Park Heights, Minnesota March 2017 • Project/Phasing Schedule,the proposed development of the 35 acres will occur over time.Therefore,dependent on the proposed land uses and the schedule to develop,the public infrastructure could be phased in over time also.The phasing alternatives will be identified and subject to change based on further review and the demand for development. Report Outcomes The final report will include an analysis of the physical layouts and estimated costs of the roadway, sewer,water and storm water infrastructure studied to serve the subject property. Financing alternatives,as coordinated with City staff,will be included. The report will be presented at a City Council workshop and/or City Council meeting,as per the City's preferences. The report will also assist the City Council in considering the following items regarding the potential annexation area: 1. What future land uses are most feasible based on the infrastructure costs? 2. What are the impacts to adjacent properties and other jurisdictions? 3. What additional properties may benefit from infrastructure extensions to the area? 4. Potential project phasing that will facilitate development of the area. Fees/Schedule The estimated fees for the Feasibility Report are$37,250.A possible schedule to complete the report is shown below: • Authorize Feasibility Report April 2017 • Meeting(s)w/City Staff May 2017 • Complete Draft Report for Review July 2017 • Present Feasibility Report August 2017 2 CITY OF �' f' CITY OFtk_ * GRANT I STiLLWATER t STILLWATER •' _ c+ TOWNSHIP n!
