A. Regulatory Compliance: All persons engaged in construction activity within the city shall operate in compliance with all state, federal, and city laws regulating or pertaining to stormwater management and runoff.
B. Erosion and Sediment Control Plan. (Rep. by Ord. 13-984)
C. City Review And Requirements: Prior to the issuance of a building permit for a new development project, the city shall evaluate the proposed project using the guidelines and BMP list approved by the California regional water quality control board, Los Angeles region and erosion and grading requirements of the city manager to determine the following:
1. Its potential to generate the flow of pollutants into the municipal storm sewer system both during and after construction.
2. How well the urban runoff mitigation plan for the proposed project meets the goals of this chapter. Each plan will be evaluated on its own merits according to the particular characteristics of the project and the site to be developed.
Based upon the review, the city may impose conditions upon the issuance of the building permit, in addition to any required by the state construction activities stormwater permit for the project, in order to minimize the flow of pollutants into the municipal storm sewer system.
No grading permit for developments with a disturbed area of five (5) acres or greater shall be issued unless the applicant can show that a notice of intent to comply with state construction activities stormwater permit has been filed and that a stormwater prevention plan has been prepared for the project.
D. Plan Approval: (Rep. by Ord. 13-984)
E. Standard Best Management Practices: Stormwater runoff containing sediment, construction waste or other pollutants from the construction site and parking areas shall be reduced to the maximum extent practicable. All construction sites shall implement an effective combination of the erosion and sediment control BMPs listed in Table 7 and/or Table 8 of the Municipal NPDES Permit (where applicable). The following best management practices shall also apply to all construction projects within the city, and shall be required from the time of demolition of existing structure or commencement of construction until receipt of a certificate of occupancy.
1. Sediment, construction waste, and other pollutants from construction activities shall be retained on the construction site to the maximum extent practicable.
2. Structural controls such as sediment barriers, plastic sheeting, detention ponds, dikes, filter berms, etc., shall be utilized to the maximum extent practicable in order to minimize the escape of sediment and other pollutants from the site.
3. All excavated soil shall be located on the site in a manner that minimizes the amount of sediments running onto the street, drainage facilities or adjacent properties and covered with appropriate materials until the soil is either used or removed from the site.
4. No washing of construction or other vehicles is permitted adjacent to a construction site. No water from the washing of construction or other vehicles is permitted to run off the construction site, or to otherwise enter the municipal storm sewer system.
F. Vegetation Clearing Limits: As a condition of granting a construction permit, the city may set reasonable limits on the clearing of natural vegetation from construction sites, in order to reduce the potential for soil erosion. These limits may include, but not be limited to, regulating the length of time soil is allowed to remain bare or prohibiting bare soil.
G. Additional Plans: The city manager may require, prior to the issuance of any building or grading permit, preparation of appropriate erosion and sediment control plans, stormwater pollution prevention or other plans consistent with the countywide development construction guidance document and the goals of this chapter.
H. Construction Activities Requiring Construction General Permit Coverage: No person shall commence or continue any construction activity in the city that causes the disturbance of one (1) acre or more of soil by clearing, grading, excavation or demolition without first demonstrating to the satisfaction of the city manager that such person has filed a "notice of intent" to comply with the Construction General Permit for stormwater discharges associated with construction activity, or has obtained a waste discharge identification number from the State Water Resources Control Board and has prepared a state Stormwater Pollution Prevention Plan (SWPPP).
Copies Of Documents: All persons engaged in construction activity within the city requiring a state construction activity stormwater permit shall have at the construction site available for review the following:
1. A copy of the notice of intent for the state construction activities stormwater permit.
2. The waste discharge identification number issued by the state water resources control board.
3. Copies of the stormwater pollution prevention plan and stormwater monitoring plan as required by the permit.
I. Inspections: Construction or work not otherwise designated as an exempt project. shall be subject to inspection by the city manager to assess whether the minimum requirements for construction development are being achieved and applicable BMPs are being implemented.
J. Compliance Waivers: Full or partial waivers of compliance with the requirements of this section may be obtained by persons who apply in writing and show that incorporation of design elements that address the objectives set forth above is an economic or physical impossibility due to the particular configuration of the site or due to irreconcilable conflicts with other city requirements. All such requests for waivers must be approved, in writing, by the city manager. (Ord. 96-799; amd. Ord. 23-1072)
