Overview and Resources

As a part of the stormwater program, the County is required to regulate new development and redevelopment projects so that they do not result in pollutants being discharged or disrupt the water balance and/or increase flows into the creeks and streams. The activities that are subject to these requirements are defined as:

  • Development: Any construction, rehabilitation, redevelopment, or reconstruction of any public or private residential project (whether single-family, multi-unit or planned unit development); industrial, commercial, retail and other non-residential projects, including public agency projects; or mass grading for future construction. It does not include routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of facility, nor does it include emergency construction activities required to immediately protect public health and safety.

 

  • Redevelopment (Significant):  Significant redevelopment is defined as the creation or addition of at least 5,000 square feet of impervious surfaces on an already developed site. Significant redevelopment includes, but is not limited to, expansion of a building footprint or addition or replacement of a structure; structural development including an increase in gross floor area and/or exterior construction or remodeling; replacement of impervious surface that is not part of a routine maintenance activity; and land disturbing activities related with structural or impervious surfaces. It does not include routine maintenance to maintain original line and grade, hydraulic capacity, or emergency construction activities required to immediately protect public health and safety


Effective January 2021, the Stormwater Quality Control Criteria Plan (SWQCCP) has new guidelines that directly impact region-wide construction projects, including post-construction runoff from new developments and redeveloped areas.
