<br />301.3.1 Nonresidential additions and alterations that cause updates to plumbing fixtures only:
<br />Note: On and after January 1, 2014, certain commercial real property, as defined in Civil Code Section 1101.3, shall have its
<br />noncompliant plumbing fixtures replaced with appropriate water-conserving plumbing fixtures under specific circumstances. See Civil Code
<br />Section 1101.1 et seq. for definitions, types of commercial real property affected, effective dates, circumstances necessitating replacement of
<br />noncompliant plumbing fixtures, and duties and responsibilities for ensuring compliance.
<br />301.3.2 Waste Diversion. The requirements of Section 5.408 shall be required for additions and alterations whenever a permit is
<br />required for work.
<br />301.4 PUBLIC SCHOOLS AND COMMUNITY COLLEGES. (see GBSC)

<br />SECTION 5.106 SITE DEVELOPMENT
<br />5.106.1 STORM WATER POLLUTION PREVENTION FOR PROJECTS THAT DISTURB LESS THAN ONE ACRE OF LAND. Newly
<br />constructed projects and additions which disturb less than one acre of land, and are not part of a larger common plan of development or sale,
<br />shall prevent the pollution of storm water runoff from the construction activities through one or more of the following measures:
<br />5.106.1.1 Local ordinance. Comply with a lawfully enacted storm water management and/or erosion control ordinance.
<br />5.106.1.2 Best Management Practices (BMPs). Prevent the loss of soil through wind or water erosion by implementing an effective
<br />combination of erosion and sediment control and good housekeeping BMPs.
<br />1. Soil loss BMPs that should be considered for implementation as appropriate for each project include, but are not limited to, the
<br />following:
<br />a. Scheduling construction activity during dry weather, when possible.
<br />b. Preservation of natural features, vegetation, soil, and buffers around surface waters.
<br />c. Drainage swales or lined ditches to control stormwater flow.
<br />d. Mulching or hydroseeding to stabilize disturbed soils.
<br />e. Erosion control to protect slopes.
<br />f. Protection of storm drain inlets (gravel bags or catch basin inserts).
<br />g. Perimeter sediment control (perimeter silt fence, fiber rolls).
<br />h. Sediment trap or sediment basin to retain sediment on site.
<br />i. Stabilized construction exits.
<br />j. Wind erosion control.
<br />k. Other soil loss BMPs acceptable to the enforcing agency.
<br />2. Good housekeeping BMPs to manage construction equipment, materials, non-stormwater discharges and wastes that should be
<br />considered for implementation as appropriate for each project include, but are not limited to, the following:
<br />a. Dewatering activities.
<br />b. Material handling and waste management.
<br />c. Building materials stockpile management.
<br />d. Management of washout areas (concrete, paints, stucco, etc.).
<br />e. Control of vehicle/equipment fueling to contractor's staging area.
<br />f. Vehicle and equipment cleaning performed off site.
<br />g Spill prevention and control.
<br />h. Other housekeeping BMPs acceptable to the enforcing agency.
<br />5.106.2 STORMWATER POLLUTION PREVENTION FOR PROJECTS THAT DISTURB ONE OR MORE ACRES OF LAND. Comply with all
<br />lawfully enacted stormwater discharge regulations for projects that (1) disturb one acre or more of land, or (2) disturb less than one acre of land
<br />but are part of a larger common plan of development sale.
<br />Note: Projects that (1) disturb one acre or more of land, or (2) disturb less than one acre of land but are part of the larger common plan of
<br />development or sale must comply with the post-construction requirements detailed in the applicable National Pollutant Discharge Elimination
<br />System (NPDES) General permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities issued by the State
<br />Water Resources Control Board or the Lahontan Regional Water Quality Control Board (for projects in the Lake Tahoe Hydrologic Unit).
<br />The NPDES permits require postconstruction runoff (post-project hydrology) to match the preconstruction runoff (pre-project hydrology) with the
<br />installation of postconstruction stormwater management measures. The NPDES permits emphasize runoff reduction through on-site
<br />stormwater use, interception, evapotranspiration, and infiltration through nonstructural controls, such as Low Impact Development (LID)
<br />practices, and conversation design measures. Stormwater volume that cannot be addressed using nonstructural practices is required to be
<br />captured in structural practices and be approved by the enforcing agency.
<br />Refer to the current applicable permits on the State Water Resources Control Board website at:
<br />www.waterboards.ca.gov/constructionstormwater. Consideration to the stormwater runoff management measures should be given during the
<br />initial design process for appropriate integration into site development.
