PROJECT DISCRIPTION
The project will construct a new 2,500 s.f. Starbucks building with a 500 s.f. patio deck and a
parking lot on a 0.39 ac lot.
SITE DISCRIPTION
The entire was previously a gas station. The site topographic relieve ranges from 62 to 66 feet
above mean sea level with the lower elevation at the south-east of the lot towards the Caltrans
ditch. Most of the site (approx. 88%) drains to this area, while a small portion of the existing site
(approx. 12%) drains toward Tamarack (north-west). The site is located at 895 Tamarack Ave in
Carlsbad California and has direct access to Tamarack Avenue.
- SCOPE AND PURPOSE
The scope of this study is to determine the detention retardation necessary to comply with CEQA's
requirement that the post developed storm water discharge from the site does not exceed the pre-
developed discharge. The storm event used for this comparison is the 100 year design storm.
HYDROLOGIC METHODOLOGY
The small size and short drainage paths of the site makes the time of concentration calculation
based on multi-sub-basin drainage paths ineffective. The calculation for the hydrologic runoff is
therefore in accordance with the County of San Diego Hydrology Manual for a small single basin
drainage shed utilizing the Rational Method equation. The time of concentration to determine the
rainfall intensity index will be the initial area qualifying time of 5 minutes as required by the County
Manual. The drainage shed area is the entire site at approximately 17,000 sf (0.39 ac) for the pre-
developed condition and the post developed condition. See exhibit B, appendix A.
The rainfall intensity (I) index was determined using the equation from the Intensity- Duration
Design Chart, Figure 3-2, taken from the San Diego County Hydrology Manual:
From:
I = 7.44PD 645
Where:
P6= 6-Hour Precipitation in inches = 2.5 inches as shown for the mainland costal
area on the County 100 year isoprofio map.
D = Duration in minutes = 5 minutes.
1=6.59 in/hr
With the intensity the peak runoff can be calculated with the rational formula:
Q=CIA
For the pre-developed condition:
C = 0.82
1= 6.59 in/hr
Al =0.34ac
A2=0.05ac
Q2 = 2.10 cfs TO AREA 2
Qi = 0.30 cfs TO AREA]
For the post-developed condition:
With 13,278 s.f. of semi-impervious surface and 3,432 s.f. of landscaped surface.
C = (0.79x 13,278 + 0.35 x 3,432) / 16,710 = 0.70
1= 6.59 in/hr
A2=0.39ac
Al =Oac
Q2 = 1.79 cfs TO AREA 2 (SEE RETARDED/ADJ
OUTFLOW TO ACCOUNT FOR BIO BASIN
WHERE Q(ADJ)=0.487 CFS TO AREA 2
Q1=O..OcfsTO AREA 1
HYDRAULIC METHODOLOGY
The peak 100 year post development discharge of 1.8 cfs is less than the pre-development
discharge of 1.84 cfs. The reduction if flow is due to the permeable payers in the parking area,
and the addition of a bio-retention basin, as well as landscaped areas. When the retardation of
the bio basin is accounted for, the total q 10 outflow is reduced to 0.487 cfs).
The project incorporates LID Bio-Retention basins that are sized in the SWMP under separate
cove, to provide a surface area that can pass and treat the 85 percentile storm event through an
amended soil medium at a filtration rate of 5 inches per hour per square foot. Therefore, the
minimum square foot area of the basin is set by LID policy including a minimum depth of filtration
medium of 1.5 feet plus a 1 foot layer of crushed rock. This 2.5 feet of material has a porosity of
40 percent. This void ratio may provide the storage volume necessary to attenuate the developed
flows. Analyzing the Bio-Retention Basins as retardation detention basins is done using a
computer application of the County of San Diego Flood Control District's Hydrology Manual. The
application includes a routine that uses the modified plus routing method to analyze the detention
basin. It is offered by CivilDesign ®Corporation and a complete program description is available
upon request.

HYDROLOGIC ANALYSIS RESULTS
Analyzing the LID Bio-Retention basin as a detention retardation basin shows that the basin
discharge can be attenuate well below the pre-development 100 year storm discharge and achieve
compliance with CEQA. See computer printout in appendix B.
The basins outlet is a 6 inch pipe. Two overflow risers are incorporated within the bio basin, These
risers will be used when ponding depth in the basin exceeds capacity. All water above ponding
design depth will bypass the bio basin and flow directly to the outlet pipe. In the event that these
inlets get clogged, all runoff will flow over the edge of the basin and toward the intended drainage
ditch.
Outlet pipe Capacity:
The calculated flow capacity of the outlet pipe is based on the critical depth of the flow through the
entrance. Considering a 6 inch (0.50 feet) diameter pipe with an entrance flow of 0.589 cfs the
critical depth is 0.39 feet and the critical velocity is 3.58 f/s. See critical depth calculator in appendix
C.
The head water build up in the overflow riser to push the required flow into the pipe is:
From the velocity head equation;
Assuming an entrance loss k = 0.2:
Headwater buildup in riser:
Vh = kV2 / 2g
Vh =1.2 (3.58)2 / 64.4 = 0.24 feet.
HW = Vh + Dc = 0.63 feet
Therefore for this flow, as long as the 6 inch outlet pipe has a slope that is steeper than the critical
slope of 1.20 percent the pipe will exhibit entrance control and the headwater will not exceed 0.63
feet. See critical slope calculator in exhibit C.
