Subject:
Professional Services Agreements for Design Services for Stormwater Improvement Projects
Policy/Action Requested:
Authorize the execution of two Professional Services Agreements with AE2S to perform design services for the Annual Erosion/Pond Cleaning/Outlet Improvements Project STORM-20-001 (projects 1, 3 and 5) in the amount of $72,869; and for the Drainage and Flood Prevention Improvements Project STORM-20-002 (projects 2 and 3) in the amount of $27,573.
Recommendation:
Authorize execution of the agreements.
Discussion:

The 2021 Capital Improvement Plan (CIP) includes projects Storm-20-001 and STORM-20-002. The CIP projects have been evaluated and updates/initiatives provided as follows:

 

Project STORM-20-001

Project Storm-20-001 includes multiple improvements to address erosion and pond maintenance issues. Feasibility studies were completed by AE2S that evaluated the improvements to address the issues. As a result of the feasibility studies, improvements were identified for project locations 1, 3 and 5 (see attached CIP Sheet for project locations). The next steps for project improvements 1, 3 and 5 are design and construction. City staff will give a presentation update on the projects (see attached).

 

The feasibility studies also identified a solution for project location 2 that will be completed by Public Works staff. The culvert at project location 4 is located on property recently purchased by the Shakopee Mdewakanton Sioux Community (SMSC) and is no longer a project that needs consideration. Project location 6 is an erosion issue that will not be addressed at this time since the cause is runoff from several stakeholders and is located on private property, currently with no easement. Project location 7 is the Quarry Lake Outlet project which is in design by the engineering firm WSB.

 

Project STORM-20-002

Project Storm-20-002 includes multiple improvements to mitigate drainage and flood prevention issues. Feasibility studies were completed by AE2S that evaluated the flooding issues and identified improvements to mitigate the issues. As a result of the feasibility studies, improvements were identified for project locations 2 and 3 (see attached CIP Sheet for project locations). The next steps for project improvements 2 and 3 are design and construction. City staff will give a presentation update on the projects (see attached).

 

The feasibility studies also evaluated flooding issues at project locations 1, 4 and 5. Improvements at these locations are not located on public property or existing easements. Additional coordination with private property owners and City of Savage is still needed prior to design and construction of these projects. These projects will continue to be advanced, anticipating projects 1 and 4 to be advanced with further property owner coordination and easement acquisition; and project 5 is expected to be pushed to 2022 in the CIP.

 

Professional Services Agreements

City staff needs assistance from a design consultant to complete the designs and assist with construction as outlined above. City staff have worked with AE2S to develop work scopes and professional services agreements that are needed to deliver the plans and specifications for these projects. AE2S has the experience, technical skill and capacity to provide the needed services and is part of the city's approved consultant pool. The attached Professional Services Agreements authorizes and describes the scope and fees for their work on these projects.

Budget Impact:

The scope of the AE2S Professional Services Agreement for the Annual Erosion/Pond Cleaning/Outlet Improvements Project Storm-20-001 (projects 1, 3 and 5) is proposed to cost (not to exceed) $72,869. The scope of the AE2S Professional Services Agreement for the Drainage and Flood Prevention Improvements Project Storm-20-002 (projects 2 and 3) is proposed to cost (not to exceed) $27,573. This work is budgeted in the 2021 CIP within the Storm Drainage Fund.
