Stormwater Checklist for Small Projects
<br /> 3 Last modified 7/1/23
<br />D. Implement construction Best Management Practices (BMPs) (Required for all projects.)
<br />D.1 Is the site a “High Priority Site”? (Municipal staff will make this determination; if the answer is yes,
<br />the project will be referred to construction site inspection staff for monthly stormwater inspections
<br />during the wet season - October 1 through April 30.) (“High Priority Sites” require a grading permit,
<br />are “hillside projects” [defined as disturbing > 5,000 sq. ft. of land area and a slope based on
<br />municipal criteria or map or > 15%] are adjacent to a creek, or are otherwise high priority for
<br />stormwater protection during construction per MRP Provision C.6.e.ii(2).)
<br /> ☐ Yes ☐ No
<br />D.2 All projects require appropriate stormwater BMPs during construction - indicate which BMPs are included in the project, below.

<br />6 Ask municipal staff for the SMCWPPP Construction BMP Plan Sheet.
<br />Yes No Best Management Practice (BMP)
<br />☐ ☐ Attach the San Mateo Countywide Water Pollution Prevention Program’s construction BMP plan sheet to
<br />project plans and require contractor to implement the applicable BMPs on the plan sheet.6
<br />☐ ☐ Temporary erosion controls to stabilize all denuded areas until permanent erosion controls are established.
<br />☐ ☐ Delineate with field markers the following areas: clearing limits, easements, setbacks, sensitive or critical
<br />areas, buffer zones, trees to be protected and retained, and drainage courses.
<br />☐ ☐ Provide notes, specifications, or attachments describing the following:
<br />▪ Construction, operation and maintenance of erosion and sediment controls, include inspection frequency;
<br />▪ Methods and schedule for grading, excavation, filling, clearing of vegetation, and storage and disposal of
<br />excavated or cleared material;
<br />▪ Specifications for vegetative cover & mulch, include methods and schedules for planting and fertilization;
<br />▪ Provisions for temporary and/or permanent irrigation.
<br />☐ ☐ Perform clearing and earth moving activities only during dry weather.
<br />☐ ☐ Use sediment controls or filtration to remove sediment when dewatering and obtain all necessary permits.
<br />☐ ☐ Protect all stormdrain inlets in vicinity of site using sediment controls (e.g., berms, socks, fiber rolls, or filters.)
<br />☐ ☐ Trap sediment on-site, using BMPs such as sediment basins or traps, earthen dikes or berms, silt fences,
<br />check dams, compost blankets or jute mats, covers for soil stockpiles, etc.
<br />☐ ☐ Divert on-site runoff around exposed areas; divert off-site runoff around the site (e.g., swales and dikes).
<br />☐ ☐ Protect adjacent properties and undisturbed areas from construction impacts using vegetative buffer strips,
<br />sediment barriers or filters, dikes, mulching, or other measures as appropriate.
<br />☐ ☐ Limit construction access routes and stabilize designated access points.
<br />☐ ☐ No cleaning, fueling, or maintaining vehicles on-site, except in a designated area where washwater is
<br />contained and treated.
<br />☐ ☐ Store, handle, and dispose of construction materials/wastes properly to prevent contact with stormwater.
<br />☐ ☐ Contractor shall train and provide instruction to all employees/subcontractors re: construction BMPs.
<br />☐ ☐ Control and prevent the discharge of all potential pollutants, including pavement cutting wastes, paints,
<br />concrete, petroleum products, chemicals, washwater or sediments, rinse water from architectural copper, and
<br />non-stormwater discharges to storm drains and watercourses.
