New Home Construction stormwater review

Beginning June 1, Development Engineering will review Stormwater Minimum Requirements (MR) #1-5 for NHC/ADS building permits. The Permit Center will notify Development Engineering staff who will reach out to the applicant to start the submittal process. This is an ENG case in CC LMS and the fee is $345.00. The applicant (creator of the job) is responsible for submittals and payments. 


Stormwater is rain that runs off hard surfaces such as rooftops, paved streets, and parking lots. As water runs off these surfaces, it can pick up pollution such as oils and dirt. Untreated stormwater might flow directly into a local stream, river or lake negatively impacting the habitat or wildlife.

Development codes and design manuals ensure compliance with the county's National Pollutant Discharge Elimination System (NPDES) Phase I Municipal Stormwater permit.
