1.0 EXECUTIVE SUMMARY

It is planned for drainage and paving improvements in the Woodshire area in the City of Houston, Texas. A site vicinity map is presented on Plate 1. The project alignment is located in 532 N and S key map of Harris County, Texas. Based on the results of Phase I Environmental Site Assessment, prepared by Geotech Engineering and Testing (GET Report No. 14-012E, dated May 12, 2015), portions of the project alignment along Fordshire Drive, from Mischire Drive to Breakwood Drive, have recognized environmental conditions (RECs). Therefore, a Limited Phase II Environmental Site Assessment (ESA) was conducted to evaluate the presence of chemicals of concern (COC) contamination along the proposed project alignment near the areas of concern (AOC). The purpose of our assessment was to estimate the degree of COC in the subsoil near the AOC. The following is a summary of our Limited Phase II ESA: 1. The subsoil conditions were evaluated by conducting three (3) borings (B-1 through B-3) to a

depth of 12 feet below the existing grade along the project alignment near the AOC. However, no groundwater was encountered at the boring locations. As a result, no groundwater sampling was performed.

2. A Photoionization Detector (PID) was used to estimate the degree of organic vapor

contamination in the soils at the boring locations. The PID screening did not show any recognizable readings on the soil samples.

3. Selected soil samples were tested for Total Petroleum Hydrocarbons (TPH), Benzene, Toluene,

Ethylbenzene and Xylene (BTEX) and Methyl tert-Butyl Ether (MTBE). 4. Our site investigation and field PID screening showed no recognizable contamination of the soil

samples at the boring locations along the project alignment near the AOC. Moreover, based on the limited laboratory chemical testing, all selected soil samples from the respective boring locations have TPH, BTEX and MTBE concentrations Below the Reporting Limit (BRL).

5. It is our opinion that this Limited Phase II ESA has revealed no recognized contamination

concentration levels in soil for COC along the project alignment near the areas of concern (AOC) in connection with the boring locations.


2.0 INTRODUCTION 2.1 General

It is planned for drainage and paving improvements in the Woodshire area in the City of Houston, Texas. A site vicinity map is presented on Plate 1. The project alignment is located in 532 N and S key map of Harris County, Texas. Based on the results of Phase I Environmental Site Assessment, prepared by Geotech Engineering and Testing (GET Report No. 14-012E, dated May 12, 2015), portions of the project alignment along Fordshire Drive, from Mischire Drive to Breakwood Drive, have recognized environmental conditions (RECs). Therefore, a Limited Phase II Environmental Site Assessment (ESA) was conducted to evaluate the presence of COC contamination along the proposed project alignment near the AOC.

The purpose of our assessment was to estimate the degree of COC contamination in the subsoils near the AOC.

3.0 FIELD EXPLORATION 3.1 Drilling and Sampling

We investigated potential contaminations of the subsoils by conducting three (3) borings to a completion depth of 12 feet below the existing grade along the project alignment near the AOC. The approximate boring locations are shown in the following table and on Plate 2. The specific boring locations are as follows:


Soil samples were obtained continuously at the boring locations from the ground surface to the completion depth of the borings at 12 feet.

Since the borings were drilled in the paved areas, pavement coring was performed prior to drilling and sampling. Soil samples were examined and classified in the field. This data is presented on the logs of borings on Plates A-1 through A-3 in Appendix A. A key to the log terms and symbols is given on Plate A-4 in Appendix A.

3.2 Photoionization Detector (PID) Field Screening

A PID was used to estimate the degree of hydrocarbon contamination in the soils in the field. The PID machine did not show any recognizable readings of the soil samples screened. The PID field readings are presented on the logs of borings in Appendix A.

3.3 Decontamination

All the sampling tools and equipments were generally decontaminated in accordance with TCEQ Standard Operating Procedure – Decontamination (SOP 1.5). All tools and equipment were rinsed with potable water and then cleaned with brush in a solution of laboratory grade detergent (Alconox) and again rinsed with potable water in order to reduce any cross contamination between the borings.

3.4 Groundwater Sampling

No groundwater was encountered at the boring locations. Therefore, no groundwater samples were collected.

3.5 Borehole Grouting

After drilling and sampling, the boreholes were grouted using Tremie method. All boreholes were grouted bottom up using Tremie pipe and cement-bentonite grout.

3.6 Sample Disposal

Soil cuttings from the drilling operation were placed in heavy duty trash bags in the field. These bags were later placed in 55-gallon drum at the GET facility. The soil cuttings were discarded, since the results of PID screening and limited laboratory chemical testing on selected soil samples from Borings B-1 through B-3 showed no recognized level of contamination for chemicals of concern (COC).

3.7 Soil Samples

The soil samples were placed in glass jars and vials in the field. The glass jars and vials were then labeled and placed in an ice-filled cooler. After chain of custody procedures were followed to maintain and document possession, the samples were transported to A&B Environmental Services, Inc. for limited chemical testing.

4.0 LABORATORY TESTS

4.1 Chemical Testing

Chemical tests were performed on selected soil samples. The chemical tests consisted of Total Petroleum Hydrocarbons (TPH), Benzene, Toluene, Ethylbenzene and Xylene (BTEX) and Methyl tert-Butyl Ether (MTBE) analyses. A & B Labs performed these chemical analysis tests under a subcontract to GET. The test results are presented in Appendix B of this report.

4.2 Sample Storage

All samples tested or not tested will be stored for a period of 60 days subsequent to submittal of this report. The samples will be discarded after this period, unless we are instructed otherwise.

5.0 GENERAL SOILS CONDITIONS 5.1 Site Conditions

The project location is located along Fordshire Drive from Mischire Drive to Breakwood Drive in the City of Houston, Texas. Currently, the project alignment is concrete-paved.

In general, residential development is located along the project alignment. Pictures of the project alignment were taken during our site visit. These pictures are presented in Appendix C.

6.0 LABORATORY ANALYSIS PERFORMED 6.1 General

Our review of the limited chemical testing analysis indicates that the MTBE concentrations of the tested soil samples are Below the Reporting Limit (BRL).

7.0 CONCLUSIONS

Our site investigation and field PID screening showed no recognizable contamination of the soil samples at the boring locations near the AOC. Furthermore, based on the limited chemical analyses, selected soil samples from the respective boring locations have TPH, BTEX and MTBE concentrations Below the Reporting Limit (BRL).

No groundwater was encountered at the boring locations. As a result, no groundwater sampling

was performed.


Therefore, it is our opinion that this Limited Phase II ESA has revealed no recognized contamination concentration levels along the proposed project alignment near the areas of concern (AOC) in connection with the boring locations tested.
