Mr. Swearingen | Arden Oaks Street Improvements Proposal for Engineering Services September 2, 2021 Page 3 Similar Projects Marie Avenue and Wesley Neighborhood Improvements, Mendota Heights, Minnesota The City of Mendota Heights retained TKDA for feasibility study, design development, bidding services, construction administration, construction observation, and construction staking for street improvements for the Wesley Lane Neighborhood and Marie Avenue between Lexington Avenue and Dodd Road. Both projects followed Minnesota Statutes 429 and involved assessments. State Aid funding was used on both projects and therefore needed to meet State Aid standards. Pavement reclamation included placement of 1” rock over the existing pavement that was mixed during the pavement reclamation. This process produced a quality aggregate base for the new roadway. Excess material was used for trail and sidewalk base. Project Included: • Reclamation of pavement and spot curb replacement • Traffic calming (bumpouts, digital speed sign) • Watermain replacement • Land bridge repair • Pond cleanout • Trail rehabilitation • Dakota County regional trail extension • Dakota County regional trail tunnel rehabilitation • Updated signage and striping • Valley Park parking lot paving SE Area Reconstruction, White Bear Township, Minnesota TKDA completed a pavement condition review of the entire White Bear Township pavement system and prepared a “Pavement Management Booklet.” The SE Area Reconstruction project includes four miles of neighborhood streets and was defined for improvements over a period of three years starting in 2020. TKDA has completed the following steps for the first phase of this project: Feasibility Report, Topographic Survey, Public Engagement, Resident Questionnaire, Public Hearings, Design Drawings, Bidding Services, Construction Administration, Construction Inspection, and Construction Staking. All streets within the first phase of the 1.4-mile project area were originally constructed in 1962. The width of each street varied between 14-feet and 30-feet and were constructed with bituminous curb. The narrow streets were widened as much as possible, but were restricted by the narrow existing right- of-way. The new bituminous street for Phase I was reconstructed with concrete curb and gutter to improve drainage and functioning of the roadway. Additional storm sewer pipe was added to address existing drainage problems, including an underground stormwater treatment structure to treat stormwater before it discharged into White Bear Lake. In addition, TKDA worked with the Rice Creek Watershed District and its cost share program to add in Rain Gardens at individual properties. TKDA held multiple neighborhood meetings, sent out residential flyers, and worked with individual residents to meet the community’s and residents’ expectations. The next phase has been ordered and construction will start in the spring of 2021.
