5 NOX, CO, and SOX emissions include running exhaust, starting exhaust, and idling exhaust. Emissions were estimated using emission factors from Tables C-3, C-4, and C-5 along with peak daily VMT and peak daily trips.
6 PM10 and PM2.5 emissions include running exhaust, tire wear, brake wear, fugitive dust, starting exhaust, and idling exhaust. Emissions were estimated using emission factors from Tables C-3, C-4, C- 5, and B-6 along with peak daily VMT and peak daily trips. 7 Off-site primary trip emissions include travel emissions (running exhaust, running loss, tire wear, brake wear, and fugitive dust), off-site evaporative emissions (hot soak, diurnal, and resting loss) using the number of round trips (i.e., half of the one-way trips), and off-site starts using the number of round trips. 8 Off-site diverted trip emissions include travel emissions (running exhaust, running loss, tire wear, brake wear, and fugitive dust). 9 On-site passenger vehicle trip emissions include travel emissions (running exhaust, running loss, tire wear, brake wear, and fugitive dust), on-site evaporative emissions (hot soak) using the number of round trips (i.e., half of the one-way trips), on-site starts using the number of round trips, and idling exhaust using the number of round trips. Since passenger vehicles turn off their engines for approximately 4 minutes while fueling on-site, they will not emit diurnal and resting loss emissions; these types of emissions occur after the engine has been turned off for more than 30 minutes. 10 On-site fuel delivery truck trip emissions include travel emissions (running exhaust, running loss, tire wear, brake wear, and fugitive dust), on-site evaporative emissions (hot soak, diurnal, and resting loss) using the number of round trips (i.e., half of the one-way trips), on-site starts using the number of round trips, and idling exhaust using the number of round trips.

Total Emissions
Notes
1 Data obtained from Table C-1. The off-site trip distance is equivalent to the average trip length minus the on-site trip distance. 2 VMT is calculated as the product of the trip distance and peak daily trips shown in this table. 3 Idle duration for passenger vehicles visiting the gas station is estimated using a maximum queue length of 4 vehicles and a transaction time of 4 minutes per vehicle. Fuel delivery truck idle duration is 5 minutes based on the CARB Air Toxic Control Measure to Limit Diesel-Fueled Commercial Motor Vehicle Idling. Available at: https://ww2.arb.ca.gov/our-work/programs/atcm-to-limit-vehicle- idling/about. Accessed: September 2021.
4 VOC emissions include running exhaust, running loss, hot soak, diurnal, resting loss, starting exhaust, and idling exhaust. Emissions were estimated using emission factors from Tables C-3, C-4, and C-5 along with peak daily VMT and peak daily trips.

1.0 INTRODUCTION

1.1 PROJECT INTRODUCTION AND BACKGROUND
The proposed project consists of the relocation of the existing fuel facility and the construction of a new parking lot at Costco Wholesa le of Culver City. The existing site consists of the warehouse, fuel facility, associate d parking, and adjacent commercial development. The project encompasses approximately 2.25 acres of this land. The scope of work to be performed consists of the demol ition of the existing fuel facility, the construction of a new parking lot, the demoliti on of several retail buildings, and the construction of the new fuel facility. The proj ect site is located at 13463 Washington Boulevard in the City of Culver City.

The project includes a new, approximately 13,000-sq uare-foot fuel canopy, the installation of 15 new multi-product dispensers (MP Ds), three (3) 40,000-gallon underground gasoline storage tanks (USTs), one (1) 1,500-gallon fuel additive UST, a new controller enclosure, a vapor processing unit, and associated site improvements, such as parking and landscaping. In addition, tempo rary noise barriers will be provided along the project’s western property line, northern property line, and the existing fueling facility’s eastern property line; the power construction equipment will contain noise shielding and muffling devices, consi stent with manufacturers’ standards; and a portion of the project constructio n activities will not occur concurrently with the City’s Washington Boulevard S tormwater and Urban Runoff Project, as further described in the Noise Study, p repared by Acoustical Engineering Services, Inc., dated February 2023.

The existing fueling facility will be razed and rem oved from the site and the existing, currently unoccupied, commercial buildings will be demolished. The existing underground storage tanks and piping will be decomm issioned and removed by state certified contractors. Following demolition, the ex isting fueling facility site will be improved with additional parking for the Costco War ehouse. The intent of the relocation is to install a new state of the art fac ility to provide a more efficient fuel purchasing experience for Costco members.

1.2 PURPOSE OF THIS REPORT
The purpose of this report is to analyze the pre an d post development hydrologic conditions, and provide a water quality analysis with prescriptive treatment design.

2.0 EXISTING TOPOGRAPHIC & HYDROLOGIC

CONDITIONS

2.1 EXISTING SITE LOCATION AND TOPOGRAPHY
The proposed Gas Station Relocation Project consist s of approximately 2.25-acres of the larger Costco Wholesale Culver City property. T he areas of work are located on the southern half of the property site. It is bound ed by the main parking lot for the Costco Warehouse to the north, Washington Boulevard to the south, an existing driveway entrance to the east, and Walnut Avenue to the west. There are two commercial buildings located between the two areas of work which are not a part of this development.

As determined from aerial photos, topographic maps and contour data, the proposed fuel facility site is relatively flat and gradually slopes towards the western portion of the site. The site generally sits slightly above grade of the adjacent streets with the biggest difference located off Walnut Avenue, at approximately two feet.

2.2 EXISTING DRAINAGE PATTERN
The existing site is sloped in such a way to direct all drainage to on-site storm drain infrastructure. Overall, the site primarily drains via surface flow and cross gutters before being collected in catch basins. All stormwa ter is then routed offsite via reinforced-concrete pipes (RCP) that ultimately dis charge into a 42-inch RCP on Washington Blvd.

At the existing fuel facility, there are a total of two existing catch basins located south of the canopy and north of Washington Blvd. These s tructures collect stormwater runoff and route it to the onsite storm drain syste m. The existing commercial development that will be converted into the new fue l facility to the west contains two cross gutters that collect stormwater runoff and ro ute it to an existing catch basin where it joins the onsite storm drain system.

2.3 EXISTING STORM DRAIN FACILITIES
There is an existing private storm drain system loc ated onsite, and all on-site drainage flows to existing catch basins. From there, it is ro uted into variously sized piping that directs flows to the southwest toward Washington Bo ulevard. After the drainage flows south off-site, it is ultimately discharged into th e 48” RCP that flows southwest underneath Washington Boulevard in the public right-of-way.

3.0 HYDROLOGY

3.1 STORM FREQUENCY
Per the County of Los Angeles Hydrology Manual, all drainage facilities in developed areas not covered under the Capital Flood protection conditions must meet the Urban Flood level of protection. As defined by the County, an Urban Flood level is runoff from a 25-year frequency design storm falling on a saturated watershed. Based on these requirements for urban floods, the design sto rm for this project is the 25-year design storm event.

3.2 METHODOLOGY
This study was prepared using HydroCalc software in conformance with the Los Angeles County Hydrology Manual. Delta flow rates and volumes are provided for comparison purposes (see Appendix C & D – Pre & Post Development Hydrology Calculations ).

3.3 EXISTING CONDITION HYDROLOGY
Currently, the project site drains via sheet flow o ver one catchment area as described in Section 2.2 (see Appendix A – Existing Condition Hydrology Map ).

Based upon the County’s guidelines, any additional runoff that exceeds that of the existing 25 year storm event must be detained onsite and released at a rate equivalent to the existing 25 year storm. The existing condit ion 25 year flow rates have been provided on the existing condition hydrology map (see Appendix A - Existing Condition Hydrology Map ).

Based upon this study and as depicted in Table 3.3.1, approximately 2.25 acres (Area A) are tributary to Washington Boulevard. This yields a 25-year event flow rate of 4.63 cubic feet per second (cfs). With the project site being in the location of an existing parking lot and commercial development, approximately 95% of the site is impervious.

See Table 3.3.2 for existing storm water discharges.

3.4 PROPOSED CONDITION HYDROLOGY
Based on the proposed site development layout and g rading, the site will follow similar drainage patterns as in the existing conditions, with flow being routed to on-site catch basins before ultimately being discharged to the existing infrastructure on Washington Boulevard. In the proposed grading desi gn, new catch basins will be installed to collect storm water runoff before ultimately being routed to the existing 48” RCP main in Washington Boulevard. See Appendix A – Proposed Condition Hydrology Map for reference.

On-site drainage will be collected in a proposed pr ivate storm drain system and treated before discharging to the public street. Wa ter quality treatment will be provided via a detention system and a proprietary b iofiltration unit on the project site.

Refer to Section 5 of this report for Low Impact Development (LID) design.

Based upon the proposed site plan, included as show n in the Post Development Hydrology Map, an average onsite impervious ratio of 95% was determined.

Using LA County’s HydroCalc software, flow rates ha ve been determined for the Low Impact Development (LID) 85
th percentile storm event, as well as the 2, 5,10, 25 , & 50 year storm events (see Table 3.4.2).

The project site will maintain a single Drainage Man agement Area (DMA) for water quality design.

Based upon a comparison of discharge rates for the tributary area described above, discharge decreases in the post-development conditi on. This is due to a longer flow path for the post-development condition. As such, d etention is not required. See comparison of pre and post conditions shown in Table 3.4.3

3.5 CEQA THRESHOLD EVALUATIONS
The following section addresses California Environm ental Quality Act (CEQA) threshold questions related to hydrology. Would the project:
a) Violate any water quality standards or waste discha rge requirements or otherwise substantially degrade surface or ground water quality?
Response: During construction, the Project would im plement an Erosion Control Plan that specifies BMPs and erosion control measur es to be used during construction to manage runoff flows. These BMPs wo uld be designed to reduce runoff and pollutant levels in runoff during constr uction. Therefore, impacts to water surface water quality during construction would be less than significant.

During on-site grading and building construction, ha zardous materials, such as fuels, paints, solvents, and concrete additives, co uld be used and would therefore require proper management and, in some cases, dispo sal. The management of any resultant hazardous wastes could increase the o pportunity for hazardous materials releases into groundwater. However, compli ance with all applicable federal, state, and local requirements concerning t he handling, storage, and disposal of hazardous waste, would reduce the potential for the construction of the project to release contaminants into groundwater. Therefore, the project would not result in any substantial increase in groundwater contamination through hazardous materials releases and impacts on groundwater quali ty during construction would be less than significant.

Under the existing conditions, there are no water q uality BMPs implemented within the project area. Under the proposed conditions, bi ofiltration BMPs will be implemented as part of the site design. Based on th e implementation of water quality BMPs consistent with the MS4 Stormwater Per mit, no violations of any water quality standards or waste discharge requirem ents are anticipated during operation and are considered less than significant. Infiltration has not been proposed as a storm water quality solution; therefo re, groundwater quality would not be affected.

Operational activities which could affect groundwat er quality include spills of hazardous materials and leaking underground storage tanks (USTs). The four USTs that will be installed as part of the project will undergo preinstallation testing to verify structural integrity and employ safety fe atures such as primary and secondary containment systems, spill containment an d overfill prevention systems, and leak detection systems. Therefore, with compli ance with applicable regulations, impacts to groundwater from the USTs would be less than significant.

The development of the expanded fuel facility would incrementally increase the use of on-site hazardous materials during operation s. However, compliance with all applicable regulations regarding the handling and potentially required cleanup of hazardous materials would prevent the project fr om affecting or expanding any potential areas of contamination, increasing the level of contamination, or causing HYDROLOGY /MS 4 STUDY
GAS STATION RELOCATION - COSTCO CULVER CITY M AY 2024

COSTCO WHOLESALE 10
regulatory water quality standards at an existing p roduction well to be violated.

Furthermore, operation of the project would not requ ire extraction from the groundwater supply. The project is not anticipated to result in releases or spills of contaminants that could reach a groundwater recharg e area or spreading ground or otherwise reach groundwater through percolation. Therefore, impacts to groundwater quality would be less than significant.
b) Substantially decrease groundwater supplies or inte rfere substantially with groundwater recharge such that the project may impe de sustainable groundwater management of the basin?
Response: The existing site condition is 95% imperv ious, and infiltration and associated groundwater recharge is highly limited d ue to very little pervious area.

Under the proposed condition, site perviousness wil l remain nearly the same and thus will allow the same or more incidental groundw ater recharge through proposed landscaping areas. Neither the existing co ndition nor the proposed project include any groundwater pumping onsite. The refore, impacts related to decreasing groundwater supplies is less than significant. c) Substantially alter the existing drainage patter n of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
i) result in a substantial erosion or siltation on- or off-site; Response: During construction, the project would be required to comply with all applicable City grading permit regulations that req uire necessary measures, plans, and inspections to reduce sedimentation and erosion . Through compliance with all NPDES General Construction Permit requirements, impl ementation of BMPs, and compliance with applicable City grading regulations , project construction would not result in substantial erosion or siltation on- or off-site.

Under the existing condition, an existing storm dra in system collects flows from the project areas and conveys flows to improved storm d rain facilities on Washington Boulevard before being ultimately discharged into M arina Del Rey. The on-site and off-site storm drain systems are fully hardened and improved and are not susceptible to erosion. The site is currently 95% impervious.

Under the proposed condition, the site will remain 95% impervious, and the proposed on-site storm drain will not be susceptible to eros ion. The existing off-site storm drain systems will continue to be utilized. Thus, the pr oject will not result in any increase in erosion on or off-site, and impacts are considered less than significant. ii) substantially increase the rate or amount of su rface runoff in a manner which would result in flooding on- or off-site;
Response: Construction activities are temporary, a nd flow directions and runoff volumes during construction will be controlled. Thr ough compliance with all NPDES HYDROLOGY /MS 4 STUDY
GAS STATION RELOCATION - COSTCO CULVER CITY M AY 2024

COSTCO WHOLESALE 11
General Construction Permit requirements, implement ation of BMPs, and compliance with applicable City grading regulations, the Proje ct would not substantially alter the project site drainage patterns during construction in a manner that would result in flooding on- or off-site.

During operation, the proposed project will not significantly alter the rate or amount of surface runoff that could impact flooding on- or of f-site. Under the proposed conditions, peak flow runoff will slightly decrease due to improved site design and a proposed storm drain system, which will collect run off to minimize on-site flooding.

Due to the slight decrease in proposed runoff condit ions, impacts related to off- site flooding are considered less than significant.
iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or
Response: As discussed above, the project would imp lement an Erosion Control Plan that specifies BMPs and erosion control measures to be used during construction to manage runoff flows and prevent pollution. These B MPs would be designed to contain stormwater or construction watering on the Project Site such that runoff will not impact off-site drainage facilities or receiving wa ter. Therefore, impacts during construction would be less than significant.

The proposed project will not create or contribute runoff that exceeds the existing capacity of the storm drain system. Implementation of biofiltration BMPs sized in accordance with the local MS4 Stormwater Permit wil l result in a decrease of proposed runoff. The existing and proposed storm dr ain systems are adequately sized to accommodate flood flows. Increases in runoff wat er will not exceed the capacity of existing or planned stormwater drainage systems. Therefore, impacts during operation would be less than significant.
iv) impede or redirect flood flows?
Response: The site is in FEMA flood zone X, and ther efore is located within an area of minimum flood hazard. In addition, the existing and proposed storm drain systems are adequately sized to accommodate flood flows. Furthe r, implementation of the project will result in a small decrease in proposed runoff. As such, the project would not alter the existing drainage pattern of the Project Site i n a manner that would impede or redirect flood flows, and impacts would be less than significant. d) In flood hazard, tsunami, or seiche zones, risk rel ease of pollutants due to project inundation?
Response: The project is not located in an area su bject to flood hazard, tsunami or seiche. The project is not located adjacent to a major body of water and is over 1.5 miles from the Pacific Ocean. The project site is not in a hillside area and is not at risk of mudflow. Therefore, impacts related to release of pollutants due to project inundation are considered less than significant.

HYDROLOGY /MS 4 STUDY
GAS STATION RELOCATION - COSTCO CULVER CITY M AY 2024

COSTCO WHOLESALE 12
e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?
Response: As discussed previously in the responses to (a) and (b), the project would implement BMPs to filter, treat, and reduce s tormwater pollutants prior to discharge from the project site in accordance with applicable regulations. Non- stormwater runoff associated with typical operation s of the Project Site would also be filtered by the BMPs provided on-site prior to d ischarging from the Project Site.

Therefore, the Project would not conflict with or o bstruct implementation of a water quality control plan or sustainable groundwat er management plan, and impacts would be less than significant.

4.0 PROPOSED ONSITE STORM DRAIN FACILITIES

Culver City, as adopted from the County of Los Ange les, enforces LID design requirements for stormwater treatments. The purpose of LID is to reuse and/or eliminate the areas of the post-development hydrogr aph by reducing the peak discharge rate, volume, and duration of flow, throu gh the use of site design and stormwater quality control measures. In general, al l proposed projects must maximize on-site retention of the StormWater Quality Design Volume (SWQDv) through (in hierarchal order): Infiltration, Stormwater Capture and Reuse, Biofiltration, or a combination thereof. The impact (cost, size, etc.) of these implementations can be minimized by maximizing pervious surfaces whether b y natural means such as landscape improvements or by introducing measures s uch as green roofing and/or permeable pavements (limitations notwithstanding).

The proposed onsite storm drain facilities will con sist of a storm water detention chamber and a proprietary biofiltration system, whi ch will intercept the low flows and provide water quality treatment in order to meet th e LA County LID Ordinance. High flows and bypass flows will flow past these structu res and be routed into the storm drain on Washington Boulevard.

The location of the detention chamber and the propr ietary biofiltration system will be provided onsite. Please see Appendix A – Proposed Condition LID Map for reference.

All onsite storm drain facilities will be privately owned and maintained by the site developer.

5.0 MS4 STORMWATER QUALITY DESIGN

This section covers the post-construction operation s of the Gas Station Relocation at Costco Wholesale Culver City, within the County of Los Angeles, California. It has been developed as required under State Water Resour ces Control Board (SWRCB) Municipal NPDES Stormwater Permit for the County of Los Angeles and the Incorporated Cities of Los Angeles County (Order No . R4-2012-0175), and in accordance with good engineering practices.

HYDROLOGY /MS 4 STUDY
GAS STATION RELOCATION - COSTCO CULVER CITY M AY 2024

COSTCO WHOLESALE 13
This Municipal Separate Storm Sewer (MS4) Plan will identify, at a minimum, the project performance criteria specified in the Los A ngeles County MS4 Permit, which details implementation of Best Management Practices (BMPs) that mitigate the project’s Stormwater Quality Design Volume (SWQDv) de fined as the runoff from the 85 th percentile, 24-hour rain event, as determined from the Los Angeles County 85 th percentile precipitation isohyetal map. BMPs selec ted shall rely on infiltration, bioretention, stormwater rainfall capture and use, and/or biofiltration, as feasible.

The Los Angeles County MS4 Permit requires the impl ementation of LID BMPs in addition to site design and source control measures . LID BMPs are engineered facilities that are designed to retain or biotreat runoff on the project site. All designated projects must detain the water quality v olume on-site through infiltration, evapotranspiration, detain water runoff, harvest an d use, or a combination thereof unless it is demonstrated that it is technically in feasible to do so. The project is a Designated Project: Redevelopment project and retail gasoline outlet categories.

Per the Los Angeles County LID Standards Manual, a Redevelopment Project category is defined as a project that results in the creatio n, addition, or replacement of either:
(1) 5,000 square feet or more of impervious surface on a site that was previously developed; or (2) 10,000 square feet or more of imp ervious surface area. Because the new development will be replacing more than 5,0 00 sf of impervious surface the project must meet County LID requirements. Retail ga soline outlets are categorized as having 5,000 square feet or more surface area, which is also applicable.

The County requires execution of a maintenance agre ement to be recorded by the property owner for the on-going maintenance of any privately maintained stormwater quality measures. The property owner is responsible for compliance with the maintenance agreement.

5.1 PROJECT PERFORMANCE CRITERIA
As mentioned, the proposed development project must mitigate the Stormwater Quality Design Volume (SWQDv) defined as the 85 th percentile depth 24-hour storm event, as determined from the Los Angeles County Hyd rology GIS isohyetal map ( see Appendix B – Site Characteristics ) (http://dpw.lacounty.gov/wrd/hydrologygis/).

Based on that electronic map, it was determined tha t the site 24-hour storm event has a rainfall depth of 1.08 inches, which was used as the LID rainfall depth in the HydroCalc software for the determination of the 24-h our runoffs. BMPs selected shall rely on infiltration, bioretention, rainfall harves t and use, and/or biofiltration, as feasible.

Due to the infeasibility of infiltration because of the shallow groundwater table, the project site will utilize a detention structure and a proprietary biofiltration system for treatment.

HYDROLOGY /MS 4 STUDY
GAS STATION RELOCATION - COSTCO CULVER CITY M AY 2024

COSTCO WHOLESALE 14

6.0 LOW IMPACT DEVELOPMENT (LID)

The Costco Gas Station Relocation project will impl ement LID BMPs in treating the site’s storm water runoff mitigation requirements. The proposed project is considered a Designated Project because the redevelopment will be replacing more than 5,000 sf of impervious surface and is also a gasoline outlet with 5,000 square feet or more of surface area. As recommended by the County of Los A ngeles Low Impact Development Standards Manual (February 2014), the selection of LID BMPs proposed for the project must follow the following order of preference: (1) infiltration, (2) capture and reuse, (3) biofiltration, and (4) other treatme nt BMPs at the discretion of the Director of Public Works that demonstrate compliance with LID design requirements to the maximum extent practicable.

6.1 INFILTRATION FEASIBILITY
Due to the nature of the project site being a gas station, infiltration will not be used.

6.2 LID CALCULATIONS
The table below outlines the input and output from the LA County HydroCalc software.

As shown, the developed LID runoff total volume is a pproximately 2,374 ft 3. Since biofiltration will be implemented, the required vol ume is 1.5 times the SWQDv or 3,561 ft 3. The project shall use a detention structure to pr ovide storage for the required treatment volume (see Table 6.2.1) . This detention structure consists of an ADS Stormtech MC-3500 chamber system that is able to contain the required SWQDv. Treatment will be handled by a proprietary Bi oclean WetlandMod biofiltration unit. This structure will treat the SWQDv and then discharge into the storm drain system.

It shall be noted that the LID area required to be t reated was further governed by an existing covenant agreement between Costco Wholesal e and the City of Culver City.

This document, titled “Cost Sharing Agreement and M emorandum of Understanding for the Washington Boulevard Stormwater and Urban R un-off Diversion System Project” outlines the agreement between the City an d Costco for the funding and design of a Stormwater and Urban Run-off Diversion S ystem. It is stated that this document represents the entire agreement between th e City and Costco regarding Costco’s SUSUMP requirements. Since a portion of th e proposed fuel facility will be located on an adjacent outparcel, this additional 0 .71-acre area will require stormwater treatment. As a result, new stormwater t reatment will only be required and provided for this limited area. Please refer to Appendix G – Stormwater and Urban Run-Off Diversion System Agreement for the aforementioned document.

1.0 PROJECT DESCRIPTION
This report presents the results of a field infiltration testing program conducted at various sites within the Marina Del Rey Watershed to assist in evaluating the Best Management Practices (BMP) design for infiltration of rain runoff. The general location of the project is shown on the Vicinity Map, Figure 1. A site plan showing the street locations where borings/field testing was performed is presented on Figure 1A. The individual boring and test locations are also indicate in Figures 2 through 9.

2.0 SCOPE OF WORK
Our scope of work included:

 Drilling a total of 11 borings ranging in depth from 6 to 25 feet.  Performing 8 infiltration tests in temporary wells installed to depths ranging in depth from

2.5 to 15 feet.
 Performing laboratory testing on representative samples of the soils encountered to assist in classification of the soils.
 A falling head permeability test was performed in each test well, after saturating the adjacent soils.
 Performing analysis of the field test data and calculation of soil infiltration rates.  Preparation of this report.

3.0 FIELD EXPLORATION AND LABORATORY TESTING

3.1 Field Exploration Program
The field program included drilling a total of 11 borings, using hollow stem auger equipment.

Falling head permeability tests were performed in 8 of the borings, established as temporary wells. The locations and depths for the borings/wells were pr ovide to us by Weston Solutions.

Locations are shown in Figure 1A and also in Figures 2 through 9.

The borings were advanced to depths ranging from 6 to 25 feet. Borin gs B-5 through B -7 are located in what is referred to as Green Streets Area 1, which includes locations in Penmar Avenue near Venice Boulevard, Walgrove Avenue and Carlton Way. Borings B-1 through B-4 are located in Green Street s Area 2, which includes l ocations in McKinley Avenue, Clement Avenue, Frey Infiltration Study February 25, 2014
Marina Del Rey Watershed BMP Design Page 2
Los Angeles, California

Avenue and Boone Avenue. Borings B-8 through B-10 are located in the Costco parking lot. Two borings were drilled at location #6, to evaluate the infiltration rate at depths of 6 to 10 feet and also at 12 to 15 feet.

The borings were performed under the observation of our staff engineer, who maintained a detailed log of each boring and assisted in obtaining soil samples. Boring logs are provided in Appendix A. Details regarding installation of the wells and conducting the infiltration t ests are provided in Sections 3.2 and 5.1, respectively.

3.2 Installation of Test Wells
Temporary test wells were installed at depth of 2.5 to 17 feet in Borings B-3, B-4, B-5, B-6A, B- 6B, B-7, B-9 and B-10. The wells consisted of 2.25-inch outside diameter PVC pipe. The bottom 2 to 5 feet of the pipe was slotted in the zone to be tested. The bottom end of the pipe was capped and set on a 1.5-foot layer of bentonite chips . In the slotted portion of the pipe gravel was used as backfill outside of the pipe . The gravel backfill was sealed just above the slotted portion of the pipe with bentonite chips, followed by native soil backfill to surface.

Before performing the infiltration tests, each well was filled with water to s aturate the surrounding soils within the test zone (Los Angeles County GS200.1) . After completion of the field test, the test wells were abandoned. The entire length of the casing was removed, and the hole was backfilled with bentonite. The top 3 feet was backfilled with soil, and the hole capped with quickset concrete or asphalt cold patch.

3.3 Laboratory Testing

Representative samples of the soils encountered in the borings were obtained and returned to our laboratory for further visual examination and laboratory testing. Laboratory tests were performed to assist in classifying the soils and included the percent passing #200 sieve , to evaluate the fines content of the samples. Discussion of the laboratory test results is provided in Section 4.2. Test results are shown on the boring logs

4.0 SITE CONDITIONS

4.1 Surface Conditions
Borings B -1 through B -7 are located in city streets. The p avement in the streets typically consisted of 5 to 8 inches of concrete over 3 to 6 inches of aggregate base, or 4 to 5 inches of asphalt over 5 to 6 inches of base. Borings B -8 through B -10 are located in the parking lot of Costco, located on the northeast corner of W. Washington Boulevard and Walnut Avenue. At test locations, the parking lot was found to have a pavement consisting of 5 inches of asphalt over 4 inches of base.

4.2 Subsurface Conditions
Detailed logs of the borings are provided in Appendix A. The subsurface conditions encountered In Green Streets 1 Area (B-5, B-6A, B-6B and B-7), Green Streets Area 2 (B-1 through B-4) and in the Costco parking lot (B-8 through B-10) are summarized in the following table. Two distinct soil layers were encountered in most borings, as indicated in the table.

B-9 17 1 – 12 Clay 12 – 17 Sand – 22%
B-10 17 1 – 12 Clay 12- 17 Sand – 44%

In Green Streets Area 1, the borings generally encountered clayey san d to sandy clay, which laboratory tests showed had 41 to 70 % fines (silt and clay content). B -3 found silty sand to a depth of about 4 feet, with 24% fines, and B-2 encountered silty to clayey sand at a depth of 6 to 10 feet, which had 12 to 44% fines.

In Green Streets Area 2 the borings found clay extending to a depth of 5 to 12 feet. The clay had 67 to 95% fines. Sand was encountered in B-5 at a depth of 5 to 10 feet, Boring B-6B between 12 and 15 feet, and B-7 between 8 and 22 feet. The sand had 10 to 44% fines.

At the Costco site, the borings found clay soils extending to a depth of 9 to a 12 that was underlain with sand to the maximum depts. Explored, which ranged from 17 to 25 feet. It is noted that Infiltration Study February 25, 2014

Los Angeles, California

similar conditions were also encountered in the extensive borings performed at the site by Kleinfelder (Kleinfelder, 1998) during their investigation for the Costco development.

4.3 Ground Water
Ground water was encountered in five of the borings at the time of drilling . The groundwater depths are summarized in the table below. In Area 1 and at Costco, the ground water was found at a depth of about 21 feet below the existing grade. In Area 2 the ground water was encountered at a depth of about 5.5 feet to 10 feet. It is noted that during the Kleinfelder investigati on for Costco, ground water was found at depths generally ranging from about 15 to 20 feet. The highest historic ground water level within the general area of the project is at a depth of 5 to 10 feet reported (CDMG, 1998). However, there is a potential for perched water to occur anywhere in the project area, where the water “perches” on top of a clay layer.

5.0 DISCUSSION

5.1 Infiltration Test Results
Following saturation, falling head permeability tests were conducted in each test well in general accordance with ASTM 5912-96 and Los Angeles County GS200.1. The well casing was filled with water and then the level of water in the well was recorded at 20 to 30 second intervals.

For calculation of the permeability, the following formula derived by Jarvis (1953) as recommended in the Ground Water Manual (US Bureau of Reclamation) was used:

K = (r1)2 / (2A t) {[(sinh –1 (A/re))/2] ln[ (2H1-A)/ (2H2-A)] - ln[ (2H1 H2-A H2)/ (2 H1 H2-A H1)]} Where:

K = average permeability of test section: m/sec, ft/sec A = length of the test section: m, ft (2 or 5 feet)
r1 = inside radius of drop pipe: m, ft (0.167 feet)
re = effective radius of test section: m, ft (0.334 feet) t = time intervals t1-t0 , t2-t1, seconds
sinh –1 = inverse hyperbolic sine
ln = natural logarithm
H = length of the water column from bottom of the test interval to water surface in the stand pipe, meters (feet) H0, H1, H2 lengths at time of measurement t0 , t1, and t2 etc.

The calculated r esults are summarized in Table 2 , and are discussed in the following Section.

Calculations are provided in Appendix B.

5.2 Discussion of Results
The following summarizes the findings of the field testing and are provided for the purpose of assessing the feasibility of this project and performing design analysis:

1. The calculated infiltration rates are summari zed in Table 1 and range from 0.005 to 0.06 inches per hour for clay layers and 0.65 to 6.5 inches per hour for sand layers. C alculated field permeability ranged from 3.2 x 10-6 to 1.2 x 10 -3 cm/sec. The calculated permeability rates are consistent with the permeability of the clay, poorly graded sand, silty sand , and gravelly sand layers encountered in the borings (Holtz et al, 1981).

2. It should be cautioned that the soil permeability and infiltration rate can decrease with time, if fines are carried into the soil by the infiltrating water.

3. We recommend that infiltration structures should be kept at least 30 feet away from buildings.
