The redevelopment of the site will consist of mixed used (residential, Office, retail), parking under building podium, driveways, associated utilities and treatment system. Project located on V-B per General plan Land Use Designation. The total site development area is ±0.46 ac.

Comparisons will be made at the same discharge points for each drainage basin affecting the site and adjacent properties. The adequacy of existing and proposed conveyance facilities affected by the project will be determined. 3.0 METHODOLOGY The Rational Method as outlined in the San Diego County Hydrology Manual, dated June 2003, was used to determine the runoff flow rate. The 100-year frequency storm event was analyzed to determine peak runoff rates discharging the site for both onsite existing and post- development. Soil type was determined to be type B from the Soil Hydrologic Groups map, NRCS Web Soil Survey (see Appendix A). The runoff coefficient “C” was determined by using the closest matching land use category in Table 3-1 (Appendix A). The exhibits have been prepared for the pre-development and post-development conditions and are attached as Exhibits “A” and “B”. Runoff coefficients, “C” are summarized below.  Pre-Development o Undisturbed Natural Terrain C = 0.25 (soil type B) o From the table 3-1, the nearest weighted C coefficient was selected per the site calculated weighted C: ((0.9*12813) + (0.25*7414)) / 20227 = 0.66 Weighted C formula used = [(0.9 x imper A) + (0.25 x perv A)] / (Total A) Basin Area Impervious Area (ac) % IMP HSG Weighted C* 1 0.46 0.29 63 B 0.66  Post-Development o Undisturbed Natural Terrain C = 0.25 (soil type B) o From the table 3-1, the nearest weighted C coefficient was selected per the site calculated weighted C: ((0.9*18488) + (0.25*1739)) / (20227) = 0.84 Weighted C formula used = [(0.9 x imper A) + (0.25 x perv A)] / (Total A) Basin Area Impervious Area (ac) % IMP HSG Weighted C* 1 0.46 0.42 91 B 0.84 4.0 HYDROLOGY 4.1 Existing Conditions The existing site is an existing office building and parking lot that all the runoff surface flow in easterly direction discharging into Roosevelt St. and then storm water enters existing curb inlet south of the project. The storm water is then conveyed to an existing 30” RCP storm 3 drain constructed per city of Carlsbad drainage 456-4J. The topography of the site is essentially a flat plain with a slight slope to the east. There is no storm drain system on the site. The site ultimately discharges into Buena Vista Lagoon within the Carlsbad Watershed. A Existing hydrology map delineating basin areas, flow paths, and concentration points has been prepared and is attached to this report as Exhibit “A”. Existing hydrology calculations can be found in Appendix B. 4.2 Post-Development Conditions The post development flow will maintain as existing drainage pattern. The entire site runoff will flow in north easterly direction via roof drains and surface into proposed treatment basin and then via proposed 12” storm drain system into the existing 30” RCP storm drain system located on Roosevelt St. The site small frontage and sidewalk on the south end portion that can’t make into biofiltration will drain offsite into Roosevelt St. and ultimately into existing inlet located downstream of the site. The site ultimately discharges into Buena Vista Lagoon within the Carlsbad Watershed. A post-development hydrology map delineating basin areas, flow paths, concentration points, and proposed drainage facilities has been prepared and is attached to this report as Exhibit “B”. Post- development hydrology calculations can be found in Appendix C. 5.0 CONCLUSION The proposed redevelopment site will maintain the flow patterns as in the Existing condition since the site proposed runoff will also discharge into existing 30” RCP storm drain system located on Roosevelt St. via proposed onsite storm drain system and concrete lug that is located just downstream of the existing curb inlet on Roosevelt St. Since the C coefficient in post condition will slightly increase compared to the existing condition, therefore the improvement of the site will have small increase in Q by 0.75 cfs which will be attenuated by construction of the biofiltration basin to reduce the post 100-year storm runoff below/equal the existing runoff. Tables 1-4 provide a summary of the pre- and post-development areas and their flows prior to discharging into offsite. All the onsite runoff after leaving the site will discharge into an existing 30” RCP storm drain system located on Roosevelt St. via proposed 12” pipe.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.
