PART IV – PROJECT DETAIL

Proper maintenance of the City owned stormwater basins is an important part of the

identified 11 BMP’s that need to be assessed to determine maintenance needs.

At a minimum include the following tasks for this project as described below:

Task 1 – Project Management:

This task includes all the meetings and coordination with the City. At a minimum, provide

monthly progress meetings and (1) meeting after the Draft Report. Provide agendas and

meeting minutes for each meeting.

Task 2 – Records Review:

Review the City provided record drawings, engineering calculations, and Operation and

Maintenance recommendations, if provided. Determine the original design intend, goals,

and function of each BMP and if the BMP was constructed in general conformance to the

plan set.

Task 3 – BMP Inspection:

Inspect each BMP to determine the need for maintenance and to determine the overall

function of the BMP. Inspections shall be performed or directed by an individual certified

to perform the work of inspection of stormwater treatment BMP’s.

Task 3a – BMP Inspection:

Use City SOP and Inspection Form to inspect each BMP to determine the need for

maintenance. Take photos to document the condition of each BMP. See Appendix

B for the City SOP and Inspection Form.

Task 3b – Topographic Survey:

Preform topographic survey of each BMP to determine the elevation of:

1. Top and toes of berms

2. BMP bottom

3. All outlets to the BMP, including emergency overflow

4. All inlets to the BMP

Task 3c – Testing:

Test pond to determine if the sediment is contaminated and to assess pond

functionality. Test sediment to MPCA sediment testing guidance, as described in

“Managing Stormwater Sediment Best Management Practices Guidance”

MPCA, December 2024.

Task 4 – BMP Modeling:

Develop up to three models, in HydroCAD, for each BMP as follows:

1. Designed Model:

a. If a HydroCAD model is provided by the City, review model and revise as

required to model the original design of the project.

b. If a HydroCAD model is not provide by the City, use record drawings to

develop a “Designed Model”.

2. Existing: Revise the Designed Model to reflect the existing condition of the BMP.

3. Proposed: Model any BMP that has been identified as being able to be retrofitted,

to show proposed improvement to the BMP.

Task 5 – Recommendations and Cost Estimate:

Recommend what, if any, maintenance is needed for each BMP. Determine if the BMP

can be retrofit to improve stormwater treatment, rate reduction, maintenance access, and
