Erosion & Sediment Control (ESC) Cost Estimate
The formula for establishing a performance guaranty sum in Section 412.080.B of the County Codes only covers the basic costs for establishing acceptable ESC measures on the construction site (stable construction entrance, perimeter protection, sediment basins, vegetative stabilization). If additional products, infrastructure, or measures are designed for the project, then these ESC measures must be itemized and included in the performance guaranty amount. If itemizing the costs is desired or required to establish the Erosion & Sediment Control Performance Guarantee amount, the estimate must include, but is not limited to, the following costs:

Retaining walls, if part of road embankment
Sidewalks (adjacent to common ground and handicap ramps)
Storm sewer systems, bridges, and culverts
