TASK 6 - CONSTRUCTION PLANS SRF will prepare construction plans for these I ected alternative, based on State Aid, MN Bicycle Facility Design Manual and other accepted design standards. The plan set shall include, but is not limited to, the following sheets: • Title Sheet Plan and Profile Sheets for • Statement of Estimated Quan- Trail, Drainage and Retaining tities and Cost Participation Walls • Construction Notes, Standard Pavement and Curb Resto- Plates, and ADA Compliance ration Sheets • Typical Sections Grading Plan • Removal Sheets Erosion Control Sheets • SWPPP Sheets • Cross Sections TH 694 Bridge Nos. 62716 & 62717 MnDOT owns the twin bridges that carry westbound (62716) and eastbound (62717) TH 694 traffic over the proposed trail improve- ments. The bridges were built in 2013 and and 2012 respectively and are in good condition. SRF has reviewed the as -built plans available on MnDOT's eDOCS Public Website. Each bridge was designed with a 12-foot trail accommodation at the base of the west slope pav- ing adjacent to the roadway's southbound shoulder. SRF has also reviewed the site and changes were implemented between the design and construction. Current conditions would allow a 12-foot trail along either side of Old Highway 10. Thus, we assume the trail can be designed and constructed below the bridges with no impact to the in -place concrete slope paving. Minor coordination for con- struction within MnDOT's right-of-way will be needed and we assume the City will need to enter into a cooperative construction agreement with MnDOT. However, no bridge modifications should be necessary. Retaining Walls The feasibility study identifies up to four (4) retaining wall systems needed beginning just north of Brueberry Lane. Review of the site indicates the wall will be needed to retain embankment used to widen the shoulder area while maintaining ditches and low wetland areas. We Assume this can be completed with simple standard wall systems such as a reinforced soil slope (RSS) or precast modular block wall (PMBW) system and fall protection railing. A brief wall type study will be conducted in conjunction with the foundation recom- mendations provided by Braun to determine the appropriate wall type. Once identified, the wall design, plans and construction cost estimating will be initiated at the 60% design stage and final wall plans and special provisions will be completed in conjunction with the overall project schedule. A refined concept layout and estimate will be submitted for review by the City at 30% and plans by both the City and County at 60% and 90%. 100% plans will be provided to the City and County for final approval. Project specifications and project manual bidding support and con- struction admin will not be provided at this time, but can be amended into the project at a later date as project funding and construction timeframe become more clearly defined. SRF will provide a pdf digital copy of final plans. SRF will delineate corridor wetlands and prepare a report to commence project permit- ting with the rice creek watershed district (RWCD). Permit applica- tions will be completed and submitted for initial review but not fully approved until construction is imminent. Wetlands are anticipated to be impacted but mitigation is unlikely. TASK 7 - EASEMENT DOCUMENTS SRF will prepare a right-of-way boundary map for Ramsey County and easement drawings and legal descriptions for up to 41 individual par- cels along the corridor requiring permanent and temporary easements necessary for installation and long term maintenance of the proposed improvements. Through the design process, we will look to reduce or eliminate the need for any easement or right -of way impacts. Acquisitions will be completed under a separate contract. Assume trail and supporting infrastructure to be located in existing right of way to extent possible. We have assumed up 10 easement graphics to account for potential temporary or permanent easements as needed. TASK 8 - COUNTY COORDINATION SRF will prepare a cost participation summary tabulation spread- sheet and project location map as exhibits to assist City and County staff in the development of a cooperative agreement for the segment of trail along Snelling Ave. SRF Consulting Group
