This past winter and early spring these roads experienced severe frost boils and rutting. The roadway drainage is poor and the ditches have filling in with sediment over the years. Neither one of these streets are programmed for paving or development in the near future. The plan is to reconstruct some of gravel section, replace it with a thicker gravel section, reestablish a ditch section and place new gravel over the street. For this work to take place survey data must be collected to generate a grading plan. Staff has used WSB for other survey and preliminary design work. There work has been acceptable. WSB’s proposal identifies the scope of services and estimated cost to complete survey work and preliminary engineering. Primary Issues to Consider • Is this work necessary? In order to generate a plan for a design to make improvements to 190th and 215th Streets survey work is necessary. • The preliminary engineering work will assist City staff in evaluating roadway improvement options and used to develop final plans.

Specifically, our services will include topographic survey and preliminary design, including draft plans and an opinion of probable cost for both the 190th Street West Ditch Grading Project and the 215th Street West Ditch Grading Project. PROJECT UNDERSTANING The 190th Street West Ditch Grading Project is located on 190th Street West between Cedar Avenue and Highview Avenue. This segment of 190th Street West is approximately 1.06 miles and is designated as a major collector. The roadway consists of a rural section with aggregate surfacing and drainage ditches on both sides. The existing drainage ditches and driveway culverts are not adequately conveying surface drainage from the roadway. The 215th Street West Ditch Grading Project is located on 215th Street West between Kenrick Avenue and CSAH 70. This segment of 215th Street West is approximately 0.79 miles and is designated as a minor collector. The roadway consists of a rural section with aggregate surfacing and drainage ditches within portions of the project corridor. The existing drainage ditches and driveway culverts are not adequately conveying surface drainage from the roadway. The scope of improvements is very similar for both projects. Proposed improvements include excavating excess material within the existing drainage ditches and re-grading the ditches to a typical slope and width. The desired ditch cross section consists of a 1:4 slope along the roadway embankment, a maximum 3-foot ditch bottom, and a 1:3 slope to tie-in to existing grades. There are a number of driveways serving properties adjacent to the roadways that have existing culverts. The scope of improvements includes evaluating these culverts and replacing or adding culverts as necessary to accommodate drainage. PROJECT APPROACH/SCOPE OF SERVICES WSB’s project scope and proposed tasks are based on our und erstanding of the project, and we propose the following scope of services: Mr. Matt Barnard October 10, 2019 Page 2 G:\Group Data\Municipal\Clients - Cities - Counties\Lakeville\Proposals\190th Street Ditch Grading Improvements\Lakeville 190th St W & 215th St W Ditch Grading Prof. Engineering Services Proposal.docx Topographic Survey Task 1 – 190th Street West Task 3 – 215th Street West WSB will complete the topographic survey for the areas identified as the 190th Street West Ditch Grading Project and the 215th Street West Ditch Grading Project. Both roadways currently exist as rural roadways with prescriptive rights to maintain the roadway measuring 66’ in width. Initially, survey controls will be set up for the project areas followed immediately by the topographic survey of the existing conditions within the extents of prescriptive rights. Driveways, mailboxes, culverts, and private utilities will also be surveyed. It is also proposed to complete the Gopher State One Call locate request for markings and maps as a part of the topographic survey work. Preliminary Design Task 2 - 190th Street West Task 4 – 215th Street West WSB will provide preliminary design services for both the 190th Street West Ditch Grading Project and the 215th Street West Ditch Grading Project which will include: • Prepare two separate draft project plans for the proposed ditch excavation and grading and culvert replacement work. The plans will include the following draft plans: o Title sheet o Proposed roadway and ditch typical section, plan and profile of the roadway centerline, and cross sections every 50-feet o Plan and profile of culvert types, sizes, locations, and elevations o Grading and construction limits for use by the City to obtain any necessary easements o Erosion control, SWPPP, and restoration plans o Cross-sections for the corridor • Prepare an Engineer’s Opinion of Probable Cost for both projects • Perform quality control reviews regularly throughout the duration of the design • Attend project meetings with City staff and design team (WSB staff) members as necessary • Coordination of design with CSAH 70 widening project as needed • For 215th Street only, WSB will also include roadway profile changes to better facilitate drainage within the project corridor. Our proposal assumes only one iteration of roadway profile changes will be required based on direction we receive for a typical ditch section standard for this corridor. Deliverables – 190th Street West and 215th Street West • 60% Draft Plan Submittal: Draft plan set for review and comment • 100% Draft Plan Submittal: Draft plan set as described above, including engineer’s opinion of probable cost Mr. Matt Barnard October 10, 2019 Page 3 G:\Group Data\Municipal\Clients - Cities - Counties\Lakeville\Proposals\190th Street Ditch Grading Improvements\Lakeville 190th St W & 215th St W Ditch Grading Prof. Engineering Services Proposal.docx Final Design, Bidding, Construction Staking, and Administration This proposal for professional services for the both the 190th Street West Ditch Grading Project and the 215th Street West Ditch Grading Project does not include services pertaining to final design, specification preparation, bidding assistance, construction staking, or construction observation.

Work Performed by the City of Lakeville It is our understanding that the City may pave theses segments of 190th Street West and 215th Street with a future improvement project and that the City will perform and coordinate all planning and design, including geotechnical work under said project. It is also our understanding that the City of Lakeville will obtain all right -of-entries or temporary easements necessary to construct the improvements based on the construction limits provided in the draft plans. Any permanent roadway easement acquisition needs will also be obtained by the City of Lakeville. Should the City require legal descriptions f or easements, temporary or permanent, WSB can provide a separate proposal to complete that work. Our scope of services does not include organizing and hosting a utility coordination meeting for the work. It is our understanding that the City will orchestrate this meeting with the preliminary plans. Schedule Based on our discussions with City Staff, we are proposing the following schedule for the 190th Street West Ditch Grading Project and the 215th Street West Ditch Grading Project. • October 21, 2019 - Approve professional services agreement with WSB • Late October, 2019 – Topographic survey of the project area • Late October thru Late November – Complete preliminary design including draft project plans and engineer’s opinion of probable cost PROPOSED FEE WSB will provide the services as outlined in Project Approach/Scope of Services.
