The following requirements and performance standards are required for erosion control:
A. Additional Requirements For Stormwater Pollution Prevention Plan: A stormwater pollution prevention plan (SWPPP) shall be submitted indicating compliance with the standards of this section. The SWPPP shall show erosion control best management practices (BMPs) to be used during construction and long term (postconstruction). The following are additional requirements for the SWPPP:
1. Erosion control BMPs, as appropriate, from the "State Of Idaho Best Management Practices For Stormwater Pollution Prevention";
2. Detailed plans showing the location of all erosion control structures, and a time schedule for installation of said structures; and
3. Location, type and amount of plant material to be used for erosion control, and the month and year that all vegetation proposed for erosion control will be planted.
B. Erosion Control Performance Standards:
1. All areas on the property graded for development, disturbed by construction, or changed in any other way which may increase soil loss due to water or wind erosion, shall be stabilized by one or more of the following methods:
a. Revegetated with plant materials including, but not limited to, flowering plants, low growing shrubs or native grasses; or
b. Stabilized with flexible, biodegradable materials or synthetic soils erosion matting in conjunction with native grasses; or
c. Other BMPs as recommended in the "State Of Idaho Best Management Practices For Storm Water Pollution Prevention".
2. Where native grasses are used for erosion control, written specifications shall be submitted to the city for approval, indicating the grass seed mix, the preparation of the seed bed, method of application and the maintenance schedule;
3. Where vegetation is proposed as an erosion control method for disturbed or graded land, the new vegetation shall be maintained until established to adequately prevent erosion; and
4. City staff shall inspect graded areas where vegetation is proposed as an erosion control measure to verify that such revegetation conforms to the submitted erosion control plan. (Ord. 382, 10-25-2006)
