19.62.100b Surfacing standards for private vehicular areas.
Areas upon private property which are required to be surfaced per the various City regulations, or pursuant to conditional approval of the Planning Commission, shall be surfaced in accordance with the requirements contained herein and with the standard specifications for public works construction and any amendments or supplements thereto, including the San Diego regional supplement amendments and the City of Chula Vista standard special provisions. Such requirements shall apply to all areas to be surfaced for the movement, parking or storage of vehicles except as specifically noted.
A. Temporary Use (Maximum of One Year). Temporary surfacing shall consist of permeable road base material suitable for light traffic or other intended use to form a permeable and dust-free surface. A weed killer shall be applied to the entire area to be surfaced in accordance with the manufacturer’s recommendations.
B. Permanent Use (for Areas Less Than 5,000 Square Feet). Permanent pavement for areas less than 5,000 square feet shall consist of a minimum of two inches of asphaltic concrete pavement with seal coat, applied over a four-inch-thick Class II aggregate base or better. Aggregate base shall comply with Section 400-2 of the San Diego regional supplement amendments and shall be compacted to 95 percent minimum relative compaction per ASTM D-1557. Native subgrade shall be graded, scarified, and compacted to 95 percent minimum relative compaction per ASTM D-1557 to a minimum depth of six inches prior to application of the asphaltic concrete structural section.
Permanent areas less that 5,000 square feet for the storage only of passenger-type vehicles may be surfaced as specified under “temporary use.” This provision shall apply only to the specific storage areas and does not include areas designated for parking or movement of vehicles.
C. Permanent Use (for Areas Greater Than 5,000 Square Feet). Permanent pavement for areas greater than 5,000 square feet for private vehicular areas shall comply with the requirements of the National Pollutant Discharge Elimination System (NPDES) Municipal Permit for San Diego Region and the City’s development storm water manual, and shall be constructed of pervious pavements such as permeable unit pavers, or porous asphalt or concrete. If impervious pavements are proposed, the runoff shall be directed to low impact development (LID) or treatment control facilities such as vegetated swales or bioretention areas. Such LID and treatment control best management practices (BMPs) shall be designed in accordance with acceptable design standards established in the City’s development storm water manual. Pervious pavements, LID features, and treatment control BMPs shall be maintained for the life of the project to function as designed to infiltrate, filter, or treat runoff from impervious areas.
