8-4B-7: CONSTRUCTION SITE RUNOFF (CSR) PERMITS:
   A.   All construction sites requiring coverage under a state permit, as well as other activities requiring building permits for new residential or new commercial construction, shall obtain a CSR permit from the city engineer. Issuance of the CSR permit requires that the applicant submit a completed city of Waterloo CSR permit application form and submit a site plan identifying BMPs, building, parking and driveway footprint, and direction of flow for site runoff. Sites that must provide an SWPPP as required by a state permit need not submit a separate site plan for their CSR permit.
   B.   Sites applying for a CSR permit that are not subject to a state permit shall meet the following requirements:
      1.   Submit a CSR permit application and related documents as described in subsection A of this section.
      2.   Implement and maintain BMPs sufficient to prevent the discharge of pollutants from the site in conformity with the requirements described in subsections 8-4B-3D2, D3 and D5 through D17 of this article.
      3.   Contact the city engineer for a preconstruction inspection prior to commencing land disturbing activities and provide access to the enforcement officer as needed to determine compliance with rules set forth in article A of this chapter and this article.
      4.   Keep plans current and provide notification to the city engineer within seventy two (72) hours of the change or addition of personnel, contractors or subcontractors, or of a substantial change of site conditions as described in subsection 8-4B-3K of this article.
      5.   Contact the city engineer for a postconstruction inspection once the site has reached seventy percent (70%) uniform coverage with perennial vegetation or equivalent stabilization and all temporary erosion control measures have been removed.
   C.   CSR permits issued to sites covered by a state permit shall remain valid until such time as the state permit authorization expires or thirty (30) days after a notice of discontinuation is submitted to the IDNR and the city engineer. If the state permit is renewed prior to expiration, the applicant must provide proof of reauthorization to the city engineer. Failure to provide proof of reauthorization shall be considered a violation of this article. In the event that a state permit is suspended, the CSR permit shall automatically expire, and the applicant must thereafter reapply for a CSR permit before resumption of permitted activities. State permit discontinuation or suspension is subject to a postconstruction inspection.
   D.   CSR permits issued to sites not covered by a state permit shall expire one year from the date of CSR permit issuance. If construction has not been completed before the date the CSR permit expires, the applicant shall renew the permit. Failure to renew the permit shall be considered a violation of this article. Closure of a CSR permit is subject to a postconstruction inspection. (Ord. 5218, 5-19-2014)
