Summary

Oceanside requires anyone conducting land disturbance or construction work to install erosion and sediment control best management practices under City Code Section 40.2.5, regardless of whether a city permit is required. A grading or building permit issued without meeting these BMP requirements is void under the same section.

(c)Minimum BMPs for land disturbance activities. Whether a city permit or approval is required or not, and whether a urban runoff management plan is required to be submitted or not, all dischargers engaged in land disturbance activities shall implement required BMPs as detailed in the city JRMP plan.(d)Control to the maximum extent practicable. All dischargers engaged in land disturbance activities must install, implement and maintain BMPs which effectively prevent non-storm water discharges into the MS4. All dischargers engaged in land disturbance activities must install, implement and maintain BMPs to reduce pollutant discharges in urban runoff from land disturbance to the MEP. BMPs must be site specific, seasonally appropriate, construction phase appropriate and implemented at the site year-round. BMPs are not limited to and must be implemented in the following categories:(1)Project planning;(2)Good site management, including waste;(3)Non-storm water management;(4)Erosion control;(5)Sediment control, including, but not limited to, dust control and offsite tracking;(6)Run-on and run-off control; and(7)Active/passive sediment treatment systems, where applicable.

Full Breakdown

Oceanside folds construction-site erosion and sediment control into its stormwater ordinance rather than a stand-alone grading chapter. 5 sets the requirements for land disturbance activities, defined broadly enough to include grading, clearing and building work. Subsection (a) makes compliance a precondition of permitting: no grading, clearing, building or other land development permit may issue without first satisfying Chapter 40, and a permit issued in violation of that rule is null and void without shielding the site from enforcement. Subsection (c) requires every discharger doing land disturbance work, whether or not a city permit or urban runoff management plan is required, to implement the minimum BMPs detailed in the city's Jurisdictional Runoff Management Program (JRMP) plan.

Subsection (d) requires those BMPs to be installed, implemented and maintained to the maximum extent practicable, site-specific, seasonally appropriate and active year-round across seven named categories, including erosion control and sediment control such as dust suppression and offsite soil tracking. Sites covered by the state's general construction stormwater permit face added duties under subsections (e) through (g): they must keep an active waste discharge identification number (WDID) and notice of intent (NOI) on file for city inspection, prepare and maintain a stormwater pollution prevention plan (SWPPP) on site, and conduct any state-required monitoring, with failure on any of these fronts treated as a separate chapter violation. 4.

Violations & Fines

Failing to implement required erosion and sediment control BMPs, or failing to maintain a state-required SWPPP or WDID/NOI on site, violates Section 40.2.5 and Section 40.3.3(d). Section 40.3.4 allows the city to prosecute as a misdemeanor or infraction and to pursue civil penalties, restoration costs and injunctive relief.

Frequently Asked Questions

Do I need erosion control on a construction project in Oceanside?
Yes. Section 40.2.5(c) requires every discharger engaged in land disturbance activity to implement best management practices detailed in the city's Jurisdictional Runoff Management Program plan, whether or not a city permit is required for the work.
What categories of BMPs must a construction site cover?
Section 40.2.5(d) lists seven required categories: project planning, good site management including waste handling, non-storm water management, erosion control, sediment control including dust and offsite tracking, run-on and run-off control, and active or passive sediment treatment systems where applicable.
What happens if a construction permit is issued without meeting these erosion rules?
Section 40.2.5(a) states that a grading, clearing, building or other land development permit issued without first meeting Chapter 40's requirements is deemed null and void, and that void status does not prevent the city from separately enforcing the chapter against the site.
