Applicant's Certification
Project Name: Barron Residence
Permit Number: LD20-0804
APPLICANT'S CERTIFICATION
I have read and understand that the City of Temecula has adopted minimum requirements for
managing urban runoff, including stormwater, from land development activities, as described in
the BMP Design Manual. I certify that this WQMP has been completed to the best of my ability
and accurately reflects the project being proposed and the applicable BMPs proposed to minimize
the potentially negative impacts of this project's land development activities on water quality. I
understand and acknowledge that the plan check review of this WQMP by City staff is confined
to a review and does not relieve me, as the Applicant, of my responsibilities for project design.
I hereby declare that the design is consistent with the requirements of the City of Temecula BMP
Design Manual, which is a design manual for compliance with local City of Temecula Stormwater
and Urban Runoff Management and Discharge Controls Ordinance (Chapter 8.28 et seq.) and
regional MS4 Permit (California Regional Water Quality Control Board San Diego Region Order
No. R9-2013-0001 as amended by R9-2015-0001 and R9-2015-0100) requirements for
stormwater management; as well as the requirements of the City of Temecula Engineering and
Construction Manual (Chapter 18) and the City of Temecula Erosion and Sediment Control
Ordinance (Chapter 18.18 et seq.).

3 If Vegetation Stabilization (Planting or Hydroseeding) is proposed for erosion control it may be installed between
May 1st and August 15th. Slope irrigation is in place and needs to be operable for slopes >3 feet. Vegetation
must be watered and established prior to October 1st. The owner must implement a contingency physical BMP
by August 15th if vegetation establishment does not occur by that date. If landscaping is proposed, erosion
control measures must also be used while landscaping is being established. Established vegetation must have a
subsurface mat of intertwined mature roots with a uniform vegetative coverage of 70 percent of the natural
vegetative coverage or more on all disturbed areas.
4 All slopes over three feet must have established vegetative cover prior to final permit approval.

Step 4: Project type determination (Standard or Priority
Development Project)
Is the project part of another Priority Development Project (PDP)? ☐ Yes No
If so, Standard and PDP requirements apply. Go to Step 4.1 and select “PDP”
The project is (select one): New Development ☐ Redevelopment 7
The total proposed newly created or replaced impervious area is: ______9,971_____ ft2
The total existing (pre-project) impervious area is: _________0______ ft2

If the total area disturbed by the project is 1 acre (43,560 sq. ft.) or more OR the project is part of a larger
common plan of development disturbing 1 acre or more, a Waste Discharger Identification (WDID) number
must be obtained from the State Water Resources Control Board.

mixed-use, and public development projects on public or private land.
Yes
☐
No
(b) Redevelopment projects that create and/or replace 5,000 square feet or more of
impervious surface (collectively over the entire project site on an existing site of 10,000
square feet or more of impervious surfaces). This includes commercial, industrial,
residential, mixed-use, and public development projects on public or private land.
Yes
☐
No
(c) New and redevelopment projects that create and/or replace 5,000 square feet or more of
impervious surface (collectively over the entire project site), and support one or more of
the following uses:

commerce.
(iv) Streets, roads, highways, freeways, and driveways. This category is defined as
any paved impervious surface used for the transportation of automobiles, trucks,
motorcycles, and other vehicles.
7 Redevelopment is defined as: The creation and/or replacement of impervious surface on an already developed
site. Examples include the expansion of a building footprint, road widening, the addition to or replacement of a
structure, and creation or addition of impervious surfaces. Replacement of impervious surfaces includes any
activity that is not part of a routine maintenance activity where impervious material(s) are removed, exposing
underlying soil during construction. Redevelopment does not include routine maintenance activities, such as
trenching and resurfacing associated with utility work; pavement grinding; resurfacing existing roadways; new
sidewalks construction; pedestrian ramps; or bike lanes on existing roads; and routine replacement of damaged
pavement, such as pothole repair.
8 Applicants should note that any development project that will create and/or replace 10,000 square feet or more of
impervious surface (collectively over the entire project site) is considered a new development.
