This Water Quality Management Plan (WQMP) has been prepared for JOE YU c/ o Brightview
Development, LLC by CalCoast Engineering & Design Group, Inc.. The WQMP is intended to
comply with the requirements of the County of Orange NPDES Stormwater Program requiring
the preparation of the plan.
The undersigned, while it owns the subject property, is responsible for the implementation of
the provisions of this plan , including the ongoing operation and maintenance of all best
management practices (BMPs), and will ensure that this plan is amended as appropriate to
reflect up-to-date conditions on the site consistent with the current Orange County Drainage
Area Management Plan (DAMP) and the intent of the non-point source NPDES Permit for
Waste Discharge Requirements for the County of Orange, Orange County Flood Control
District and the incorporated Cities of Orange County within the Santa Ana Region. Once the
undersigned transfers its interest in the property, its successors-in-interest shall bear the
aforementioned responsibility to implement and amend the WQMP. An appropriate number of
approved and signed copies of this document shall be available on the subject site in perpetuity.

Section IV Best Management Practices (BMPs)
IV. 1 Project Performance Criteria
Describe project performance criteria. Several steps must be followed in order to determine what
performance criteria will apply to a project. These steps include:
• If the project has an approved WIHMP or equivalent, then any watershed specific criteria
must be used and the project can evaluate participation in the approved regional or sub-
regional opportunities. (Please ask your assigned planner or plan checker regarding
whether your project is part of an approved WIHMP or equivalent.)
• Determine applicable hydromodification control performance criteria. Refer to Section 7.II-
2.4.2.2 of the Model WQMP.
• Determine applicable LID performance criteria. Refer to Section 7.II-2.4.3 of the Model WQMP.
• Determine applicable treatment control BMP performance criteria. Refer to Section 7.II-3.2.2 of
the Model WQMP.
• Calculate the LID design storm capture volume for the project. Refer to Section 7.II-2.4.3 of the
ModelWQMP.
(NOC Permit Area only) Is there an approved WIHMP or equivalent
for the project area that includes more stringent LID feasibility
criteria or if there are opportunities identified for implementing LID
on regional or sub-regional basis?
If yes, describe WIHMP
feasibility criteria or
regional/ sub-regional LID
opportunities.

Describe an alternative compliance plan (if applicable). Include alternative compliance obligations
(i.e., gallons, pounds) and describe proposed alternative compliance measures. Refer to Section 7.II
3.0 in the WQMP.
IV.4.1 Water Quality Credits
Determine if water quality credits are applicable for the project. Refer to Section 3.1 of the Model
WQMP for description of credits and Appendix VI of the Technical Guidance Document (TGD) for
calculation methods for applying water quality credits.
Description of Proposed Project
Project Types that Qualify for Water Quality Credits (Select all that apply):
-□Redevelopment
projects that reduce the
overall impervious
footprint of the project
site.
□Brownfield redevelopment, meaning
redevelopment, expansion, or reuse of real
property which may be complicated by the
presence or potential presence of hazardous
substances, pollutants or contaminants, and
which have the potential to contribute to
adverse ground or surface WQ if not
redeveloped.
--□ Higher density development projects which
include two distinct categories ( credits can only
be taken for one category): those with more
than seven units per acre of development (lower
credit allowance); vertical density
developments, for example, those with a Floor
to Area Ratio (FAR) of 2 or those having more
than 18 units per acre (greater credit allowance).
D Mixed use development, such as a
combination of residential, commercial,
industrial, office, institutional, or other land
uses which incorporate design principles that
can demonstrate environmental benefits that
would not be realized through single use
projects ( e.g. reduced vehicle trip traffic with
the potential to reduce sources of water or air
pollution).
--□ Transit-oriented developments, such as a D Redevelopment projects
mixed use residential or commercial area in an established historic
designed to maximize access to public district, historic
transportation; similar to above criterion, but preservation area, or similar
where the development center is within one significant city area
half mile of a mass transit center (e.g. bus, rail, including core City Center
light rail or commuter train station). Such areas (to be defined through
projects would not be able to take credit for mapping).
