[Ord. No. 16-008 §1, 6-13-2016]
A. 
The intent of this Chapter is to protect and enhance the water quality of local receiving waters in a manner pursuant to and consistent with the Federal Clean Water Act and also to provide for the health, safety, and general welfare of the citizens of the City through the regulation of non-stormwater discharges to the municipal separate storm sewer system (MS4) according to locally approved standards as required by Federal and State law. The objectives of this Chapter are:
1. 
To regulate the contribution of pollutants to the MS4 by stormwater discharges from construction activity and development;
2. 
To reduce pollutants in stormwater discharges from construction activity by guiding methods for control of stormwater runoff quantity and/or quality; and
3. 
To enable legal authority to carry out all inspection, surveillance, monitoring and enforcement procedures necessary to ensure compliance with this Chapter.
