§ 55.25 CONSTRUCTION SITES.
   Any person performing construction work in the city shall comply with the provisions of this chapter and other applicable county and city ordinance for erosion and sediment control and any subsequent revisions.
   (A)   All persons engaged in construction activity within the city shall operate in compliance with all state and federal laws regulating or pertinent to storm water management and runoff including operating with all required permits. The Director of Public Works or designee may require that such permits be displayed at the work sites as a condition of continuing to perform the construction.
   (B)   No person shall commence or continue any construction activity in the city that causes the disturbance of one acre by clearing, grading, excavating, or reconstructing existing facilities involving removal and replacement without demonstrating to the Director of Public Works that such person has obtained a National Pollution Discharge Elimination System General Permit for Storm Water Discharges Associated with Construction Activity (Construction Storm Water Permit) from the State Water Resources Control Board. For purposes of the Construction Storm Water Permit, construction activity requiring a permit does not include:
      (1)   Routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility; or
      (2)   Emergency construction activities required to protect the public health and safety.
   (C)   Properties of one acre or greater in size shall be designed to retain the 100-year 24-hour duration storm on site. Refer to Chapter 162, Grading for more information.
   (D)   Any person engaged in a construction activity requiring a Construction Storm Water Permit shall retain at the construction site the following documents:
      (1)   A copy of the Notice of Intent to comply with the requirements of the General Permit for Storm Water Discharges Associated with Construction Activity;
      (2)   A waste discharge identification number issued by the State Water Resources Control Board; and
      (3)   A duly issued Storm Water Pollution Prevention Plan and Monitoring Program Plan for the construction activity requiring the construction permit.
   (E)   Any person engaged in construction activity requiring a Construction Storm Water Permit shall provide any of the documents described in division (D) of this section to the city upon request of the Director of Public Works or designee.
   (F)   Prior to the issuance of any building or grading permit for the construction of new development or redevelopment, a Water Quality Management Plan (WQMP) and Stormwater Pollution Prevention Plan (SWPPP) must be submitted and approved. The Director of Public Works or designee shall evaluate the proposed project to determine its potential to generate illicit discharges into the municipal storm drain system. Based upon this evaluation, the city may require that conditions be placed upon the issuance of the building or grading permit to minimize the risk of discharge of pollutants into the storm drain system. The imposition of conditions under this section shall be based on the standards set forth in the most recent edition of the California Storm Water Best Management Practice Handbooks (Municipal, Industrial/Commercial, and Construction volumes) and additional standards as determined by the city.
   (G)   Subject to all of the provisions of this chapter, the following additional requirements shall apply to persons conducting construction in the city for which a certificate of occupancy is required as well as the owners of such property. The requirements set forth below shall apply at the time of demolition of an existing structure or commencement of construction and until receipt of a certificate of occupancy.
      (1)   Runoff containing sediment, construction waste and other pollutants from construction sites and construction vehicles and equipment parking areas which is likely to enter the storm drain system shall be reduced to the maximum extent practicable.
      (2)   Where determined necessary by the Director of Public Works or designee, a temporary sediment barrier shall be installed.
      (3)   Between October 1 and April 1 of each year, the owner of property or any person performing improvements on such property shall use a plastic or other covering, along with additional runoff control devices if necessary to intercept and safely convey the runoff on unprotected areas to control run-off of pollutants. Provisions and Best Management Practices of the site specific Stormwater Pollution Prevention Plan (SWPPP) must be in place and the document on site for inspection.
      (4)   Excavated soil shall be located on the site in a manner that minimizes the amount of soil transported into the public right of way onto adjoining properties. Soil stockpiles shall be covered with plastic or other covering until the soil is either used or removed.
      (5)   Washing industrial or construction equipment or vehicles is not allowed on city rights of way or private roadways adjacent to a construction site. No person shall allow water from vehicles or equipment on a construction site to run-off into the city's storm drain system.
      (6)   Drainage controls shall be utilized as needed to prevent illicit discharge, depending on the extent of proposed grading and topography of the site, including but not limited to the following:
         (a)   Detention ponds, sediment ponds, or infiltration pits;
         (b)   Dikes, filter berms or ditches; or
         (c)   Downdrains, chutes or flumes.
   (H)   The city may, as a condition of granting a building or grading permit, set forth reasonable limits on the clearing of vegetation from construction sites, including but not limited to, regulating the length of time during which soil may be left bare.
