The information below is a list of documents required to be submitted with the CSR permit application process for construction sites disturbing an acre or greater:

Construction Stormwater Runoff (CSR) Permit Pre-requisites for Industrial, Commercial, and Residential Development with an acre or greater of land disturbance activity

• A copy of the Developer’s IDNR NPDES General Permit No.2 Notice of Intent
• Copy of the site’s NPDES General Permit No.2
• Copies of any other state and federal permits associated with surface water discharge
• SWPPP Narrative – A document narrating existing site conditions, contact information, potential sources of pollution, detailed information of individual erosion and sediment control practices to be utilized as sediment runoff prevention, etc. To assist with the development of a SWPPP the City has provided a Storm Water Pollution Prevention Plan Outline, and Iowa Statewide Urban Specifications manual for a list of controls and practices, including their specs.
• Construction Site Schedule - An electronic construction schedule form is provided to fill out through the City’s new permitting management system during the CSR permitting process.
• Contractors/Sub-Contractors SWPPP Certification/Agreement – All contractors and sub-contractors are required by state law to agree to the terms and sign the certification/agreement.
  • Contractor certification agreement
  • Sub-contractor certification agreement
• A NPDES General Permit No.2 Transfer Agreement – An agreement between the permittee of the existing NPDES General Permit No.2 and the new owner of the future developing lot to set-forth coverage or non-coverage to the new owner is required if the project site is part of a larger NPDES General Permit No.2 permitted development project.
  • Same Transfer Agreement
  • Separate Transfer Agreement 
• 3 Phase Erosion Control Plan Set – See below for a list of common practices for each phase by project type. (Please remember to apply grading strategies into the design to reduce the length of time a disturbed area is vulnerable to the elements, and to integrate offsite and onsite runoff management practices.)
• Linear and Residential Development Projects (Accompanying each phase below is a listing of the most common types of erosion and sediment control practices associated to that phase.)

• Grading Phase – Perimeter controls, construction entrance drives, stockpile

   stabilization, fuel barrel secondary confinement tank, etc.

• Infrastructure Phase – Perimeter controls, construction entrance drives, inlet protection, interior sediment controls, ditch checks, concrete washout, staging area, fuel barrel secondary confinement tank, temporary or permanent stabilization of inactive areas, permanent stabilization of drainage ways (incorporating matting practices), solid waste disposal units, etc.

• Stabilization Phase – Sediment controls (perimeter protection for hydro-seeded

  areas), permanent stabilization practices, area and field inlet protection, etc.

• Commercial and Industrial Projects

• Grading Phase – Perimeter controls, construction entrance drives, stockpile stabilization, fuel barrel secondary confinement tank, etc.
• Building Phase - Perimeter controls, construction entrance drives, inlet

   protection, interior sediment controls, concrete washout, staging area, fuel barrel secondary confinement tank, temporary or permanent stabilization of inactive areas, permanent stabilization of drainage ways and storm water facilities, etc.

• Stabilization Phase – Sediment controls (perimeter protection for hydro-seeded areas), permanent stabilization practices, area and field inlet protection, etc.
