Attach the following documentation with your credit application for each of the Credits you are applying to receive.

1)       Detention Credit –Provide drawings and calculations to verify that the storm water runoff from the site is detained to at least 5% less than the predevelopment rate for a 24-hour, 2-, 10- and 100-year runoff event. Possible 25% credit available.

2)       Retention Credit –Provide drawings and calculations to verify that the parcel retains or infiltrates at least 1 inch runoff volume calculated over the entire site. Retention or infiltration must be done in an on-site, constructed storm water management facility. Please provide documentation that clearly states that the landowner will be responsible for maintaining the management facility (Maintenance agreement). Possible 25% credit available.

3)       Water Quality Credit – Provide documentation demonstrating the water quality improvement. It is required that the documentation be prepared by a licensed professional engineer of the State of Minnesota. Also provide the necessary drawings and calculations to support the storm water benefit. It is the applicant’s responsibility to prove the benefit. Possible 50% credit based proportionally on treatment capacity (load reduction) for a 24-hour, 2-inch rainfall event.

4)       Regional Treatment Credit – Provide drawings and calculations to verify that at least 75% of the parcel’s runoff directly enters a regional treatment facility by storm sewer or overland flow.

Possible 25% credit based on above credit requirements.

5)       Green/Vacant Space Land Use Credit – Provide a diagram(s) and documentation that clearly dimensions the green/vacant space and shows that the green/vacant space meets all of the following criteria:
