Summary
The City of Bellflower, Los Angeles County requires a state NPDES construction stormwater permit before grading one acre or more, and requires City-approved erosion-control BMPs before a grading permit issues on smaller sites.
No person shall be granted a grading permit or shall commence or continue any construction activity in the City that causes the disturbance of one acre or more of soil by clearing, grading, and excavating without demonstrating to the City that such person has obtained a NPDES general construction activity stormwater permit from the SWRCB. NPDES construction activity does not include: 1) routine maintenance to maintain original line and grade; 2) hydraulic capacity; 3) the original purpose of the facility; or 4) emergency construction activities required to immediately protect the public health and safety.
B. Any person engaged in a construction activity in the City requiring a NPDES construction permit shall retain at the construction site the following documents: 1) a copy of the notice of intent to comply with terms of the general permit to discharge water associated with construction activity; 2) a waste discharge identification number issued by the SWRCB; 3) a stormwater pollution prevention plan and monitoring program plan for the construction activity requiring the construction permit; and 4) records of all inspections, compliance and noncompliance reports, evidence of self-inspection and good housekeeping practices.

Full Breakdown
Before Bellflower will grant a grading permit or allow construction disturbing one acre or more of soil, the applicant must demonstrate to the City that a NPDES general construction activity stormwater permit has been obtained from the State Water Resources Control Board. Projects disturbing less than an acre still cannot get a grading permit without agreeing to implement City-prescribed best management practices to curb pollutant runoff. Permit holders must keep stormwater pollution prevention plan and inspection records on-site for at least three years. This applies only inside Bellflower city limits.
Violations & Fines
Proceeding with grading or construction without the required NPDES permit or City-prescribed BMPs is a violation of Chapter 13.20, enforced under BMC Chapter 1.08 as a misdemeanor (up to $1,000 fine/six months jail) or infraction ($100-$500), and is a public nuisance the City may abate.
