Proposed Improvements Sunwood Drive is a Municipal State Aid (MSA) street and must conform to MSA design standards, including meeting a 10-ton pavement design standard. Because the existing pavement section is only 4.2-inches of bituminous over 2.2-inches aggregate base (6.4-inch total section), the typical full -depth reclamation (FDR) process cannot be used to meet pavement strength design requirements. Staff is proposing to place 4-inches of new bituminous over 6-inches aggregate base. This will be achieved by removing the existing pavement and aggregate base, removing an additional 4-inches of subbase material, and placing 6-inches of new aggregate base and 4-inches of new bituminous pavement. Ideally the new aggregate base will be made of recycled reclamation material, but to allow for the best bidding environment, the project will not require it. The existing concrete curb and gutter is proposed to remain in -place with spot replacements. Per the ADA Transition Plan, existing pedestrian ramps will be updated to current ADA standards. There are 10 such pedestrian ramps within the project area. Replacing the pedestrian ramps will also result in three concrete valley gutters being replaced. Review of the geotechnical report found clean sands, ideal for both utility and pavement support within the project area. Additionally, groundwater is not anticipated to be a concern for the street reconstruction. Improvements to the existing municipal utilities are not anticipated other than a minor improvement to a watermain gate valve identified by the City Utilities Department. Additional Permitting Sunwood Drive is an MSA street, approval by the MnDOT MSA department was received prior to bidding the project. Because the project goes up to the Anoka County right-of-way, and will require temporary signage within said right-of-way, an Anoka County Highway Department Right -of -Way Permit will be required. No other permits are anticipated.
