Attachment A Proposal to Provide Engineering Services To: Mr. Todd Blomstrom Public Works Director/City Engineer City of Arden Hills From: Sean Delmore, PE, PTOE Erik Seiberlich, Project Manager Date: July 30, 2019 Re: Scope and Cost Estimate for Lake Valentine Roadway Improvement Recommendations Study The City is currently working with Mounds View Public Schools and Wold Architects & Engineers on site developments for the Mounds View High School on Valentine Road. As part of the school development process, a traffic and parking lot study was completed by Wenck in May of 2019. The City of Arden Hills has received negative comments about the future site plan and is very concerned about the limited scope of that study as well as the safety and operational deficiencies in some of the key recommendations. WSB was asked to develop a more comprehensive set of recommendations based on a broader look at the area rather than try to fit recommendations in to the existing constraints of the Lake Valentine Road corridor. This broader look assumes that geometric revisions can be made to the existing roadway and parking lot entrances. Also, recommendations will be made for modifications to the north parking lot and entrance area (future parent drop off) to the school to enhance the safety and operations of the future pedestrian crossing. The following is a summarized scope for professional engineering services relating to improvements proposed for Lake Valentine Road in the direct vicinity of Mounds View High School for the City of Arden Hills. This proposal includes data collection, development of concepts for improved circulation, alternative evaluation, and recommendations for site revisions and appropriate traffic control adjacent to Mounds View High School on Lake Valentine Road. The study will be completed in collaboration with the City of Arden Hills and Mounds View Public Schools. The project tasks include: Data Collection — Use video cameras at up to four locations for weekday data collection. The extracted counts will be used along with 2018 data to determine the existing conditions a.m. and p.m. peak hour turning movement counts for use in modeling and analysis. As part of the traffic data collection, WSB staff will collect speed data and perform sight distance calculations to be used for the school speed zone evaluation. Staff will also review the most recent traffic study and document any hazards adjacent to the school and provide information on mitigation. Development of Concepts — The WSB team will create geometric concepts for the area. The concepts will be created based on the results of the traffic analysis and coordination with the City of Arden Hills. We anticipate three (3) concepts will be developed for the area. These concepts may include, but are not limited to, additional turn lanes, approach realignments, entrance relocations, entrance closures, and median additions. WSB will create a preliminary opinion on probable costs for each of the concepts. The concepts will be discussed with the City and further revisions will be made as requested.
