Covering material will be anchored to ensure adequate protection. Erosion control measures will remain in place until soil stabilization can be achieved by the installation of permanent surfacing. The use of landscape surfacing BMPs shall be coordinated with the project landscape plans. There will be no soil stockpiles after construction. Dust control will be utilized as necessary at the Contractor's discretion by keeping the work area adequately moisture conditioned.

This will be accomplished through the use of catch basin inserts and pavement sweeping. The construction drawings detail the location and protection measure required for each existing adjacent catch basin to be protected. Inlet protection filters are required on all existing catch basins near the area of work. Filters will be inspected frequently ' during construction (especially after storm events) and pavement will be checked and swept as necessary. If inlet protection filters become filled to one-third of available storage with sediment, they will be cleaned in such a manner as to prevent sediment from entering the stormwater drainage system. Inlet protection material will also be kept on hand in case additional protection becomes necessary. Applicable BMPs: BMP C220: Storm Drain Inlet Protection Element 8- Stabilize Channels and Outlets No conveyance channels are proposed to manage stormwater on the finished site. The use of channels during construction to carry construction stormwater is at the discretion of the contractor.
