means the rate and amount of erosion caused by development
activities that exceed the natural processes by which the surface

the results specified in this title.
means a registered architect licensed by the state of California.
means the ground surface conditions extant on completion
of grading.
means any program, activity, technology, process, siting
criteria, operational method, practice, facility and/or procedure
that when properly implemented will control, prevent, remove or reduce
pollutants in discharges. "Source control" BMPs (both structural and
nonstructural) are operational practices or methods that prevent pollution
by reducing potential pollutants at the source. A "site design" BMP
is a source control BMP and means any design feature that reduces
the creation or severity of potential pollutant sources or reduces
the alteration of the project site's natural flow regime. "Treatment
control" BMPs are structural methods of treatment to remove pollutants
from urban runoff. (The city utilizes the BMPs which have been specified
in the city's jurisdictional urban runoff management program (JURMP).
Presently, these BMPs have been developed, and may be amended from
time to time, by the California Stormwater Quality Association (CASQA)
and can be referenced at www.cabmhandbooks.com. The city reserves the right to implement any equivalent BMP prepared
by other qualified water quality organizations or government agencies.)

earth material on which fill is to be placed or within a cut or fill

soils, such as of materials from two natural soil horizons, or for
the intermixing or admixing and compaction of natural site soils with
imported soil or other materials.
means soil, rock or other material acquired from an off-site
location for use in the planned grading.

which show the construction site perimeter, existing and proposed
buildings, lots, roadways, storm water collection and discharge points,
general topography both before and after construction, and drainage
patterns across the project. The SWPPP must list best management practices
(BMPs) the discharger will use to protect storm water runoff and the
placement of those BMPs. Additionally, the SWPPP must contain a visual
monitoring program; a chemical monitoring program for "non-visible"
pollutants to be implemented if there is a failure of BMPs; and a
sediment monitoring plan if the site discharges directly to a water
body listed on the 303(d) list for sediment.
