Temecula Valley Hospital Northeast Parking Expansion
Water Quality Management Plan (WQMP) Provisions
September 13, 2017
The project site is located in the City of Temecula in Riverside County. The proposed
development includes the construction of a new parking field in the northeast corner of the
master site plan, sidewalk improvements and modifications to get to the parking lot,
landscaping and drainage swale improvements from the new parking field to the existing
detention basin and water quality swale located to the west of the parking field and north of
the hospital.
The proposed development of the parking lot expansion, as shown on the Phase 1 BMP Plan
(see WQMP-1), drains to Detention Basin C which is identified as a treatment BMP. The Phase
1 Drainage Area Map (see WQMP-3) shows that this Subbbasin No. 32 drains to that detention
basin for treatment and then is collected and routed into Infiltration Basin A. Per the original
WQMP, Detention Basin C was already sized to treat the entire area where the proposed
parking lot expansion is located as if that subbasin were entirely a parking lot with a C-factor of
0.83 (see WQMP-3 and Worksheet 1 for Detention Basin "C"). The pervious areas of the
proposed development will be self-treating landscaped areas. Therefore,there is no need for
the addition of any new BMPs.
The design of the proposed development accounts for treatment of the new impervious area
and is consistent with the overall water quality treatment for the site. It will not adversely
impact the in-place treatment measures currently maintained on-site.

1. Determine Design Volume (Use
Worksheet 1)
a. Total Tributary Area (minimum 5 Atotai= acres
ac.) VBMP= f&it 4 ft3
b. Design Volume, VBMp
2. Basin Length to Width Ratio (2:1 min.) Ratio= a ; I L:W
3. Two-Stage Design
a. Overall Design
1) Depth(3.5' min.) Depth = ft
2) Width (30' min.) Width = ft
3) Length (60.' min.) Length = — ft
4) Volume (must be >_ VBMp) Volume = / C. ft3
b. Upper Stage
1) Depth (2' min.) Depth = ft
2) Bottom Slope (2%to low flow Slope = %
channel recommended)
c. Bottom Stage
1) Depth(1.5'to 3') Depth = ft
2) Length Length = ft
3) Volume (10 to 25% of VBMp) Volume = ft3
4. Forebay Design
a. Forebay Volume (5 to 10%of VBMp) Volume = ft3
b. Outlet pipe drainage time (-L-445 Drain time= minutes
min)
5. Low-flow Channel
a. Depth (9" minimum) Depth = ft
b. Flow Capacity(2* Forebay Qou-r) QLow Flaw=_ Cls
6. Trash Rack or Gravel Pack (check one) Trash Rack Gravel Pack L'

7. Basin Outlet
a. Outlet type (check one) Single orifice ..�'
Multi-orifice plate
Perforated Pipe
Other
b. Orifice Area Area = ft
2
c. Orifice Type Type
d. Maximum Depth of water above Depth = ft
bottom orifice
e. Length of time for 50%VBMP Time 50% = hrs
drainage (24 hour minimum)
f. Length of time for 100%VBMP Time 100% = 2, hrs
drainage (between 48 and 72
hours)
