Subject: Hex Chrome Analysis addition
Attachments: J25765-1 UDS Level 2 Report Final Report.pdf EXTERNAL EMAIL*

Hi Steve,

It’s me again. Would it be possible to have all samples on this report (B19-0.5, B19-3.0, B20-0.5, B20-3.0, B21-0.5, B21-

3.0, B22-0.5, B22-3.0, B23-0.5, B23-3.0, B24-0.5, B24-3.0, B25-0.5, and B25-3.0) run for hex chrome EPA 7199, reported to MDLs, on a 48-hour TAT (or let me know earliest possible TAT if that’s not possible)? Can you please let me know the cost per sample on that as well?

Thanks!!

Receipt
The samples were received on 4/14/2020 2:18 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 3.8º C.

GC/MS VOA
Method 8260B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 570-63155 and analytical batch 570-63151 were outside control limits. Sample matrix interference is suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

GC Semi VOA
Method 8081A: The continuing calibration verification (CCV) associated with 570-63508 recovered high and outside the control limits for < Endosulfan sulfate> on one column. Results are confirmed on both columns and reported from the passing column.

Method 8081A: The native sample, matrix spike, and matrix spike duplicate (MS/MSD) associated with preparation batch 570-63514 and analytical batch 570-63508 were above the calibration range. Due to the additional level of 4,4'-DDE present in the spiked samples, the concentration of 4,4'-DDE in the MS/MSD was above the instrument calibration range. The data have been reported and qualified.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Metals
Method 6010B: The absolute response for Molybdenum was greater than the method reporting limit (RL) in the following sample: B23-0.5 (570-25765-9).

The instrument raw data has been manually reviewed and the result can be reported as ND.

Method 6010B: The absolute response for Selenium was greater than the method reporting limit (RL) in the following sample: B23-3.0 (570-25765-10).

The instrument raw data has been manually reviewed and the result can be reported as ND.

Method 6010B: The absolute response for Selenium was greater than the method reporting limit (RL) in the following samples: B24-0.5 (570-25765-11), B24-3.0 (570-25765-12), B25-0.5 (570-25765-13) and B25-3.0 (570-25765-14).

The instrument raw data has been manually reviewed and the result can be reported as ND.

Method 6010B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 570-63379 and analytical batch 570-63760 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Organic Prep
Method 3545: Due to the matrix, the initial volume(s) used for the following sample deviated from the standard procedure: B23-3.0 (570-25765-10). The reporting limits (RLs) have been adjusted proportionately. The initial mass was changed from 20g to 10g due to limited samples.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

VOA Prep
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.

Re: Cameron Ln. Property (APN 167-042-08)
17631 Cameron Lane
Huntington Beach, CA 92647
OCHCA Case #20IC002

BACKGROUND

The project site (Site) is a 0.79 acre unpaved lot with a vacant single family home within an area of mixed commercial and residential use that is bounded by commercial properties to the north, an unpaved vacant property to the south, Beach Boulevard to the west and Cameron Lane to the east in the City of Huntington Beach, California. The future planned use of the Site is an asphalt- paved lot with a large tent structure to provide temporary shelter for people experiencing homelessness, as ordered by the Governor’s Executive Order N-32-20, issued by Governor Newsom on March 18, 2020. Investigations of the Site were conducted by EEC Environmental (EEC) in several phases to assess the presence of contaminants that may have impacted the Site.

Contaminants of concern found in soil at the Site were pesticides, hexavalent chromium and lead. On April 22, 2020, Orange County Health Care Agency (OCHCA) was contacted by the City of Huntington Beach requesting OCHCA review of EEC’s Phase I report and assessment reports. On April 27, 2020 the City of Huntington Beach entered into a Remedial Action Agreement with the OCHCA for oversight at the above referenced site (Case No. 20IC002). As such, OCHCA has prepared this site summary and recommendations for the Site.

SITE INVESTIGATION AND LIMITED EXCAVATION

According to EEC’s March 2020 Phase I report, the Site consists of one residential home that was built in 1947 and indicated past row crop agricultural use from the 1930s to the 1950s.

Subsurface investigations of the Site were conducted from April 6, 2020 through May 11, 2020.

On April 6, 2020 a total of six soil borings (B1 through B6) were advanced throughout the Site at depths ranging from 0.5 to 3 feet (ft) below ground surface (bgs). Soil samples were submitted for analysis of Title 22 Metals (metals) including hexavalent chromium, organochlorine pesticides (OCPs) and chlorinated herbicides. Samples with contaminant concentrations that exceed background and screening levels
1 were found at the Site. Lead was identified in one soil sample (B4 at 0.5 ft bgs) at a concentrations of 101 milligrams per kilograms (mg/kg) near the current vacant single family residential home. Toxaphene was identified in one soil sample (B6 at 0.5 ft bgs) in the western portion of the site at a concentration of 770 micrograms per kilogram (ug/kg). Hexavalent chromium was detected in soil samples from boring locations B4, B5 and B6 with a maximum concentrations detected at 820 ug/kg (B6 at 3 ft bgs). All other analytes were below background and screening levels.

Based on these findings, EEC two excavations were dug on April 13, 2020, to remove 2.78 cubic yards of contaminated soil which has been stored in drums on site pending disposal.

Confirmation soil samples were collected on April 13, 2020 from the excavation sidewalls and bottoms (B11 through B18). Soil samples were submitted for analysis of lead and OCPs. Results of confirmation sampling around soil boring location B4 indicated that elevated lead concentrations were removed and remaining soil is below residential screening levels

2. Results
of confirmation soil sampling around soil boring location B6 indicated that toxaphene impacts were still present. Soil borings (B7 through B10, B26 through B32, B4B, B5A, B6B, B7A, B8A, B9A and B10A) were also drilled and sampled between April 13 and May 11, 2020 to depths ranging from 0.5 to 8 ft bgs to further delineate impacts at the Site. Soil samples were submitted for analysis of metals including hexavalent chromium, OCPs and chlorinated herbicides.

Toxaphene was detected in five soil samples at 0.5 ft bgs (B7, B10, B11, B29 and B32) with a maximum concentration of 1,600 ug/kg. and 4,4 dichlorodiphenyldichloroethylene (DDE) was identified in one soil sample (B-7 at 0.5 ft bgs) at a concentration of 3,100 ug/kg. Hexavalent chromium was detected in nine soil borings at depths ranging from 0.5 to 8 ft bgs. (B4B, B5A, B6B, B7, B7A, B8, B9, B9A and B10) with a maximum concentration of 980 ug/kg. All other analytes were below background and screening levels

3. In addition, three grab groundwater
samples were collected at locations GW-1, GW2 and GW-3 on May 11, 2020. Groundwater samples were submitted for hexavalent chromium analysis and were not detected above the reporting limits of 0.028 micrograms per liter (ug/L). All sampling and assessment was conducted by prior to the initiation of OCHCA oversight, however all of the data was provided to OCHCA and additional sample analysis occurred following our involvement.

CONCLUSION AND RECOMMENDATION

Several phases of investigation were conducted at the Site, results of which showed the presence of 4,4 DDE, toxaphene and hexavalent chromium in excess of site screening levels and to a lesser extent lead in soil. Based on OCHCA’s review of the information noted above, soil impacts located beneath the proposed asphalt cover are not considered to be a threat to the occupants of the temporary tent structure. Soil contamination however, must be addressed if changes to site use occur. Additional site assessment may also be required if changes to site use occur. It is the property owner’s responsibility to notify this Agency if there is any change in site use and/or if there are future findings of additional contamination at the Site. Additionally, any excavated soil for tent structure installation must be managed, handled, and disposed of properly, in accordance with all regulatory requirements to minimize exposure to workers and the community.

If you have any questions regarding this matter, please contact me at (714) 433-6011.

OCHCA Case #20IC002
BACKG
ROUND
The pr
oject site (Site) is a 0.79 acre unpaved vacant lot in an area of mixed commercial and residential use. The Site is bounded by commercial properties to the south, Beach Boulevard to the west, Cameron Lane to the east, and the Cameron Ln. Property located at 17631 Cameron Lane (Cameron Ln Property) to the north. The Site and the Cameron Ln Property are both part of the current site development project and Orange County Health Care Agency (OCHCA) Industrial Cleanup Case No. 20IC002 (see attached Site Summary and Recommendations letter). The future planned use of the Site is an asphalt- paved lot with a large tent structure to provide temporary shelter for people experiencing homelessness, as ordered by the Governor’s Executive Order N-32-20, issued by Governor Newsom on March 18, 2020. This Site is a continuation of the Cameron Ln. Property. Investigations of the Site were conducted by EEC Environmental (EEC) in several phases to assess the presence of contaminants that may have impacted the Site.

Con
taminants of concern found in soil at the Site were hexavalent chromium and lead. On July 6, 2020, OCHCA was contacted by the City of Huntington Beach requesting OCHCA review of EECs June 25, 2020 Site Assessment Report for the Site referenced above. On April 27, 2020 the City of Huntington Beach entered into a Remedial Action Agreement with the OCHCA for oversight at the Cameron Ln. Property.

On July 17, 2020 the City of Huntington Beach entered into a revised Remedial Action Agreement that included the Cameron Lane Property and the above referenced Site (Case No. 20IC002). As such OCHCA has prepared this Site Summary and Recommendations for the Site.

SITE INVESTIGATION
Accor
ding to EEC’s March 2020 Phase I report, the Site consists of two former single family residential homes, one irrigation well (OCWD well number W-4150/State well number 05S/11W-25M09), a cesspool that was abandoned in place and indicated past row crop agricultural use from the 1930s to the 1950s. Additionally, the Phase I report noted potential buried debris at the Site based on uneven topography. Subsurface investigations of the Site were conducted from April 14, 2020 through July 21, 2020. A total of seventeen soil borings (B19 through B25, B33 through B40, B19-A and B22-A) were advanced throughout the Site at depths ranging from 0.5 to 15 feet (ft) below ground surface (bgs).

Select soil samples were submitted for analysis of Title 22 Metals (metals) including hexavalent chromium, organochlorine pesticides (OCPs), mercury, volatile organic compounds (VOCs), semi-VOCs, and total petroleum hydrocarbons (TPH). Samples with contaminant concentrations that exceeded screening levels1 were found at the Site. Lead was detected in soil samples from soil boring locations B22, B33 and B35 with a maximum concentration detected at 145 milligrams per kilograms (mg/kg) near one of the the former single family residential home. Hexavalent chromium was detected in soil samples from boring locations B19, B36, B37, and B38 with a maximum concentrations detected at 450 ug/kg (B38 at 5 ft bgs). All other analytes were below background and current screening levels2.

POT

ENIAL DEBRIS EXPLORATION AND EXCAVATION
A geop
hysical survey was conducted at the Site by SubSurface Surveys, under the supervision of a State Registered Geophysicist, on April 13, 2020. Based the geophysical survey, two areas of potential buried debris were identified. On July 22, 2020 limited investigation excavations with areas of approximately 8 ft by 7 ft by 2 ft deep were conducted under OCHCA oversight. A buried metal fence and old sewer pipe was discovered in one area of concern. Small pieces of metal debris were found in the second area of concern. No evidence of contamination was found during this investigation. Excavated soil was placed back in the small excavations and debris was left onsite for future disposal. The geophysical survey report erroneously indicates the site address as 17631 Cameron Lane in Huntington Beach, however, figure 3 and photographs 1 through 10 show the survey was conducted on the property at 17642 Beach Boulevard. The purpose of the geophysical survey was to locate and identify the existence of any underground storage tanks (USTs), backfilled excavations, piping, conduit, and other buried features that may exist within the survey area. Several inactive buried utility lines and areas with buried metal debris were identified across the site. However, no buried features were detected in the southeast corner of the site, where records indicate that a groundwater production well (State Well Number 05S/11W-25M09) had been located.

CONCLU

SION AND RECOMMENDATION
Sever
al phases of investigation were conducted at the Site, results of which showed the presence of lead and hexavalent chromium in excess of site screening levels. Based on OCHCAs review of the information noted above, soil impacts located beneath the proposed asphalt cover are not considered to be a threat to the occupants of the temporary tent structure. Soil contamination however, must be addressed if changes to site use occur. Additional site assessment may also be required if changes to site use occur. It is the property owner’s responsibility to notify this Agency if there is any change in site use and/or if there are future findings of additional contamination at the Site. Additionally, any excavated soil for tent structure installation must be managed, handled, and disposed of properly, in accordance with all regulatory requirements to minimize exposure to workers and the community. If the irrigation well that had been installed in the southeast corner of the Site is encountered during grading or excavation, a well destruction permit must be obtained from this office.

If you
have any questions regarding this matter, please contact the undersigned at (714) 433-6251.

BACKG
ROUND
The
project site (Site) is a 0.79 acre unpaved lot with a vacant single family home within an area of mixed commercial and residential use that is bounded by commercial properties to the north, an unpaved vacant property to the south, Beach Boulevard to the west and Cameron Lane to the east in the City of Huntington Beach, California. The future planned use of the Site is an asphalt-paved lot with a large tent structure to provide temporary shelter for people experiencing homelessness, as ordered by the Governor’s Executive Order N -32-20, issued by Governor Newsom on March 18, 2020. Investigations of the Site were conducted by EEC Environmental (EEC) in several phases to assess the presence of contaminants that may have impacted the Site. Contaminants of concern found in soil at the Site were pest icides, hexavalent chromium and lead. On April 22, 2020, Orange County Health Care Agency (OCHCA) was contacted by the City of H untington Beach requesting OCHCA review of EECs Phase I report and assessment reports. On April 27, 2020 the City of Huntington Beach entered into a Remedial Action Agreement with the OCHCA for oversight at the above referenced site (Case No. 20IC002). As such OCHCA has prepared this site summary and recommendations for the Site.

SITE INVESTIGATION AND LIMITED EXCAVATION

According to EEC’s March 2020 Phase I report, the Site consists of one residential home that was built in 1947 and indicated past row crop agricultural use from the 1930s to the 1950s. Subsurface investigations of the Site were conducted from April 6, 2020 through May 11, 2020. On April 6, 2020 a total of six soil borings (B1 through B6) were advanced throughout the Site at depths ranging from 0.5 to 3 feet (ft) below ground surface (bgs). Soil samples were submitted for analysis of Title 22 Metals (metals) including hexavalent chromium, organochlorine pesticides (OCPs) and chlorinated herbicides. Samples with contaminant concentratio ns that exceed background and screening levels
1 were found at the Site. Lead was identified in one soil sample (B4 at 0.5 ft bgs) at a concentrations of 101 milligrams per kilograms (mg/kg) near the current vacant single family residential home. Toxaphene was identified in one soil sample (B6 at 0.5 ft bgs) in the western portion of the site at a concentration of 770 micrograms per kilogram (ug/kg). Hexavalent chromium was detected in soil sample s from boring locations B4, B5 and B6 with a maximum concentrations detected at 820 ug/kg (B6 at 3 ft bgs). All other analytes were below background and screening levels.

Based on these findings, EEC two excavations were dug on April 13, 2020, to remove 2.78 cubic yards of contaminated soil which has been stored in drums on site pending disposal. Confirmation soil samples were collected on April 13, 2020 from the excavation sidewalls and bottoms (B11 through B18). Soil samples were submitted for analysis of lead and OCPs. Results of confirmation sampling around soil boring location B4 indicated that elevated lead concentrations were removed and remaining soil is below residential screening levels

2. Results of confirmation soil sampling
around soil boring location B6 indicated that toxaphene impacts were still present. Soil borings (B7 through B10, B26 through B32, B4B, B5A, B6B, B7A, B8A, B9A and B10A ) were also drilled and sampled between April 13 and May 11, 2020 to depths ranging from 0.5 to 8 ft bgs to further delineate impacts at the Site. Soil samples were submitted for analysis of metals including hexavalent chromium, OCPs and chlorinated herbicides. Toxaphene was detected in five soil samples at 0.5 ft bgs (B7, B10, B11, B29 and B32) with a maximum concentration of 1,600 ug/kg. and 4,4 dichlorodiphenyldichloroethylene (DDE) was identified in one soil sample (B -7 at 0.5 ft bgs) at a concentration of 3,100 ug/kg. Hexavalent chromium was detected in nine soil borings at depths ranging from 0.5 to 8 ft bgs. (B4B, B5A, B6B, B7, B7A, B8, B9, B9A and B10) with a maximum concentration of 980 ug/kg. All other analytes were below background and screening levels

3. In addition, three grab groundwater samples were collected at locations GW-1, GW2 and GW-3 on May 11, 2020. Groundwater samples were submitted for hexavalent chromium analysis and were not detected above the reporting limits of 0.028 micrograms per liter (ug/L). All sampling and assessment was conducted by prior to the initiation of OCHCA oversight, however all of the data was provided to OCHCA and additional sample analysis occurred following our involvement.

CONCLUS

ION AND RECOMMENDATION
Seve
ral phases of investigation were conducted at the Site, results of which showed the presence of 4,4 DDE, toxaphene and hexavalent chromium in excess of site screening levels and to a lesser extent lead in soil. Based on OCHCAs review of the information noted above, soil impacts located beneath the proposed asphalt cover are not considered to be a threat to the occupants of the temporary tent structure. Soil contamination however, must be addressed if changes to site use occur. Additional site assessment may also be required if changes to site use occur. It is the property owner’s responsibility to notify this Agency if there is any change in site use and/or if there are future findings of additional contamination at the Site. Additionally, any excavated soil for tent structure installation must be managed, handled, and disposed of properly , in accordance with all regulatory requirements to minimize exposure to workers and the community.

AESCO Project No. 20211195-G5642

Dear Ms. Raszewski:

At your request AESCO is submitting preliminary foundation recommendations for the above- referenced project. As labor atory te sting is currently in progr ess, t hese preliminary recommendations are based only on the field dat a (visual description and blow count during sampling) obtained during drilling. These recommendations will be updated once the laboratory testing is completed.

Project Description

The new facility will be a 5-story building having a footprint of approximately 50,000 square feet and consisting of a residential and health services healing center . The ground floor will consist mainly of a parking lot with a Welcome and Assessment Center , a Sobering Cen ter and two lobbies at the front.

Although the structural design has not been performed, we understand that the building will have a 2-story podium slab concrete frame su pporting a 3-story wood frame structure. The following provided loads are estimated for this type of structure:

• Column Loads = 300 kips to 350 kips total DL+LL

Considering the anticipated loads, the new building column and wall loads should be supported by drilled cast-in-place concrete piers. A first-floor concrete slab on grade can be designed with additional site preparation.

Preliminary recommendations for drilled piers and the first-floor slab are provided in this letter.

Building Borings B-1 through B-5

The boring location map building borings B-1 through B-5, is attached in Appendix A.

The five building borings, borings B -1 through B -5, mainly encountered mainly dense to very dense silty sands to depths of 38 feet to 50 feet below grade. However, there were a few isolated silty clay layers/lenses within the silty sands and boring B -1 encountered clay/silty clay in the top 4 feet . In borings B -3, B-4 and B -5, hard silty clays were generally encountered below a depth of 38 feet below grade and extended to the bottom of the bo rings at 50 feet , except for boring B -5 where silty sand was again encountered at 48 feet to 50 feet below grade.

Groundwater was initially encountered at a depth of 30 feet below grade in all five borings; final water levels were measured varying between 26 feet and 31 feet below existing grade.

The surficial clayey soils , where encountered , appear to have a low to moderate expansion potential that need to be addressed in the design. Note: surficial clays were more predominant in the borings for the Temporary Tent Shelter installed immediately north of these recent borings.

Preliminary Drilled Pier Foundation Recommendations
Based on the anticipated column and wall loads of the facility, the building will require support on typical, reinforced concrete drilled piers. The support from each pier will be derived from side friction and end bearing for axial loads, and from passive soil resistance for lateral and over - turning forces.

Based on our exploratory boring data , design parameters are provided i n the L oad Data for Drilled Piers table in the attached Appendix B. T he allowable axial loads for the drilled pier are tabulated for various sizes of shafts to a depth of 50 feet. AESCO recommends that the drilled piers to be less than 30 feet to minimize groundwater infiltration during drilling operations. The allowable load is calculated for a s afety factor of 3.0. We estimate that settlement of the pier would be less than ½ inch.

For the 300-kip to 350 -kip column loads we recommend that a 36-inch diameter to 42 -inch diameter, 25-foot deep drilled pier be designed for axial loading, or as deemed necessary by the Structural Engineer.

An equivalent fluid with a density of 300 pounds per cubic foot may be assumed for determining the lateral resistance of the soils against the projected width of the pier to a depth of 10 feet. The maximum lateral resistance should be limited to 3000 psf below a depth of 10 feet. Th e allowable resistance is calculated for a safety factor of 2.0; no additional resistance for temporary wind and seismic loading should be used.

Installation may require tempor ary casing to be used or using drilling mud to advance the holes due to presen ce of groundwater and most of the soils are sil ty clays and silty sands that are subject to sloughing or caving.

First Floor Slab on Grade
The existing surficial clay soils, where encountered, appear to have a low to moderate expansion potential, resulti ng in shrinking or swelling of the se soils with changes in moisture content.

These movements could result in dis tress and cracking of a ground -supported floor slab. In addition, our experience at the site has indicated disturban ce due to numerous underg round utilities. Therefore, in order to mitigate potential movements due to these soils it is recommended that a thickened floor slab be utilized and the upper 5 feet of existing soils be excavated beneath the building footprint, extending out to a distanc e of 5 feet outside the building li mits, and replaced with non-expansive compacted engineered fill.

We anticipate that the first-floor concrete slab on grade for the new structure wil l extend about 4 inches above the final adjac ent grade. The floor slab s hould have a minimum thickness of 8 inches as the majority of the first floor will be used for parking . We recommend that the slab sections be properly reinforced with a minimum of two ro ws of #5 bars, at 16 inches, on center, each way, positioned top and bottom, placed on approved subgra de and have thickened edges with a minimum embedment (depth to bottom of edge) of 1 2 inches below finished grade. Th e actual reinforcement should be desi gned by the Structural Engineer. The fill m aterial should be tested and monitored during placement by the Geotechnical Engineer or his representative. Slabs on grade should be underla in by a minimum of 5 feet of engin eered fill. A ten mil PVC or polyethylene membrane with a four -inch gravel blank et should be provided bel ow all interior slabs to prevent moisture migration. The gravel blanket should be a clean 3/8 -inch diameter gravel placed to prevent migration of moisture to the slab through capillary action.

The site should be cleared of vegetation, debris, concrete, organic matter, abandoned utility lines, contaminated soils (if any), and unsuitable material. Any existing fill e ncountered during site preparation should be excavated to the depth of the fill and to a horizontal distance equal to the depth of excavation. As a minimum, the upper five feet below the existing surface in the building area should be over -excavated and re placed with imported engineered fi ll compacted to at least 95 percent r elative compaction as determined by ASTM D15 57 at moistur e contents 1 to 3 percent above optimum moist ure. The bottom of the excavation shall be inspected by the Geotechnical Engineer to confirm competent soil is reach ed. The side slopes of shallow excavations should be cut at a gradient no steepe r than 1:1 (h orizontal to vertical), while excavations gre ater than 5 feet high should be cut to a gradient no steeper than 1.5:1.

Excavations should not extend below an imag inary 1.5:1 inclined plane projecting below the bottom edge of adjacent existing foundations a nd/or utilit ies unless properly shored or AESCO Project No. 20211195-G5642

Construction Material Testing/Inspection  Environmental  Geotechnical Engineering Services

specifically analyzed further. All excavations should be observed by AESCO to confirm that all unsuitable material is removed from beneath the planned construction prior to placing fill.

The bottom of all excavations to receive compacted fill should be scarified to a depth of 6 inches, moisture conditioned to at least optimum water content , and compacted as described above .

Excavations below the final grade level should be properly backfilled using ap proved fill material. Th e backfill and any additional fil l should be placed in loose lifts less than 8 inches thick, moisture conditioned to 0 to 4 percent above optimum wate r content and compacted as directed above. Engineered fill should consist of soi ls with a maximum particle size of 3 inches, at least 80 percent passing the ¾-inch sieve and with an expansion index not greater than 20. Fi ll materials should be free of con struction debris, roots, organic matt er, rubble, contaminated soils, and any othe r unsuitable or deleterio us material as determined by the Geotechnical Engineer.

The clayey on-site soils do not appear to be suitable for use as c ompacted engineered fil; the on- site silty sands can be used as engineered fill but are highly susceptible t o strength loss and pumping when wet and care must be taken to protect these soils from saturation. We recommend that any imported fill material used be analyzed for acceptability by the Geotechnical En gineer prior to importing it to the site for use as engineered fill.

Please contact us if you have any questions or if we may be of any additional assistance.

Sincerely,
AESCO, Inc.
