Site maps should show the construction activities and stormwater management practices for each major phase

of construction (e.g., initial grading, infrastructure, construction, and stabilization). Site maps should identify

the following features:

• Stormwater flow and discharges

• Areas and features to be protected

• Disturbed areas (locations and timing of activities)

• Clearing limits

• Identify locations of structural and non-structural BMPs

• Identify locations of Post-construction BMPs

• Areas of stabilization

• Indicate locations of material, waste, borrow, or equipment storage

The site map should show changes that have been made to the construction site, BMPs and stabilization meth-

ods as the site progresses. The Missouri State Operating Permit requires that the SWPPP and site map be kept

up to date, so mark up the site map with the locations and dates of any changes being made. Also include the

current locations of the following:

• Portable toilets

• Material storage, vehicle and equipment fueling and maintenance areas

• Concrete, paint and stucco washouts

• Dumpster containers

• Spill kits

• Stockpiles

• Any other non-structural non-stormwater BMPs, temporarily removed structural BMPs or changes to the

structural BMPs

• Environmentally Sensitive Areas

• Stream Buffers
