About this file
This is an Erosion Control Plan attachment for the City of Wichita's Public Works & Utilities Department, prepared for the Veranda Second Addition paving project (Phase 2) in Wichita, Kansas. The plan outlines comprehensive erosion control measures required during construction, including temporary and permanent seeding specifications, site preparation requirements, and stormwater pollution prevention protocols. Key construction elements include approximately 2.07 acres of annual ryegrass seeding at 150 lbs./acre with slow-release fertilizer, approximately 85 square yards of Curlex or Excelsior blanket installation, 440 linear feet of back-of-curb protection, 4 ditch checks, 2 curb inlet protection devices, and a stabilized construction entrance. All disturbed areas exceeding 14 days must receive permanent seeding with turf reinforcement matting where indicated, and seed shall be distributed at 1/4-inch depth using approved mechanical equipment followed by prairie hay mulch at 2 tons/acre. The plan was issued for construction on August 5, 2026, at a scale of 1 inch equals 20 feet.
The contractor is responsible for maintaining and implementing all erosion control measures throughout construction phases, with modifications subject to approval by the owner's representative. Weekly Best Management Practice (BMP) inspection reports must be completed and maintained on-site, with additional reports required within 24 hours of any rainfall exceeding 1/2 inch. The contractor must prevent silt or sediment from entering adjacent properties, remove any mud tracked onto adjacent paved areas or streets by end of business each day, and maintain a site entrance sign displaying contact information, the Notice of Intent/Stormwater Pollution Prevention Plan (NOI/SWPPP), and the erosion control plan location. All erosion control work must comply with federal, state, county, and local code standards, and the contractor shall maintain existing BMPs from previous project phases.
