The City of Pearland's particular interest is the area bounded on the north by E. Broadway, south by Mary's Creek, east by Old Alvin Road, and west by SH-35. This proposal describes the scope of work, engineering fees, and schedule for the Old Townsite DS and PER. BACKGROUND The Old Townsite development is partially developed and has a great potential for master planning. The planning area corresponds to an area of 195 acres. One of the City's goals for this planning area is to encourage development by using regional detention for drainage. Property owners would avoid on-site detention and able to develop more property: The City would like to develop a Preliminary Engineering Report including regional detention and trunk storm sewer lines to facilitate development. The scope of work that addresses the City's goals is presented in Exhibit A. Again, Dannenbaum appreciates the opportunity to present this proposal and be of assistance to you. We are looking forward to this assignment. The engineering fee spreadsheet and the schedule are attached. If you have any questions or wish to discuss this proposal, please do not hesitate to call me at 713-527-6365. Sincerely yours, Alejandro C.

(QCL) understands that we have been selected based on qualifications to provide preliminary geotechnical engineering services for the project referenced above. This document has been prepared in general accordance with project information provided to us on h' April 11,2014. E? Project Description We understand the consideration is being made to construct a detention basin within a tract of land toughly bound by Old Alvin Road, South Main Street, East Walnut Street, and Swensen Road in Pearland, Texas. At the time of this document, the location and configuration of the proposed basin was not available. However, we understand the basin will have a maximum depth of 12 feet and sideslopes no steeper than 3 Horizontal: 1 Vertical. In addition, we understand that the basin will be designed in accordance with Harris County Flood Control f; r District(HCFCD) criteria. The purpose of this study is to obtain soil information from widely-spaced borings to provide a general description of the soil stratib aphy, groundwater conditions, and provide preliminary recommendations for basin sideslopes. iG Houston League City I' 10810 Northwest Freeway 400 Hobbs Road,Suite 210 Houston,Texas 77092 League City,Texas 77573 Tel: 713-695-1133 Tel: 281-3324378 Fax: 713-695-0808 Fax: 281-332-8399 gclabs(gigclahs.com Cost Estimate for Geotechnical Engineering Services Page 2 Proposed Detention Basin—Old Town Site Apr 116,2014 Pearland,Texas QCL Document No.: 39311 Scope of Services A brief summary of the services to be provided by QCL is presented in the following paragraphs. li Field Investigation: The field exploration will be performed to obtain subsurface !I information regarding soil type, soil stratigraphy and groundwater depth. For this project, we plan to drill and sample a total of three (3) widely-spaced borings to depths of 30 feet within the proposed detention basin area. Drilling will be performed using all-terrain vehicle (ATV) mounted drilling equipment. Soil samples will generally be obtained continuously to a depth of 20 feet and at five feet intervals thereafter to the termination depths of the borings in accordance with HCFCD criteria. Soil samples will also be evaluated in the field using a pocket penetrometer and/or SPT blow counts, depending on the soil type. The depth of groundwater will be observed during drilling and at approximately 24 hours after drilling.At the completion of our field program, the boreholes will be backfilled with grout. QCL will notify Texas811, a utility location service, to locate the primary utilities. This utility location service will only locate utilities within dedicated public utility easements.If underground utilities are known to exist in the vicinity of the borings, QCL should be provided the opportunity to review utility plans to avoid the existing lines. Laboratory Testing: The engineering properties of selected soil samples will be evaluated by our A2LA accredited laboratory. Laboratory tests may include, but not limited to, moisture content, unit weight, unconfined compression, consolidated undrained (CU) triaxial (with pore pressure measurements), Atterberg Limits, Crumb Test,Pinhole Dispersion,and percent passing the No. 200 sieve. e, Engineering Analysis and Report: The field and laboratory data will be reviewed by an engineer who will also perform appropriate engineering analyses. The findings of the preliminary investigation will be presented in an engineering report prepared under the supervision of a Texas Professional Engineer. The report will include the following: i Logs of Borings,Plan of Borings,water observations, and laboratory test results;.and o Detention pond design guidelines per I-ICFCD, including slope stability (short term,, long term,and rapid draw down conditions) and excavation and groundwater control. 6 Cost Estimate for Geotechnical Engineering Services Page 3 Proposed Detention Basin—Old Town Site April 16,2014 Pearland,Texas QCL Document No.: 39311 Please note that this scope of services does not include foundation recommendations for any bridges and/or culverts that may be planned within the detention basin area. Fees The fee for this project will be charged on a Lump Sum basis. Based upon the scope of services presented here, the estimated fee is $7,430. The cost of our services for this effort will not exceed these figures unless the scope of work is modified with the approval of the client. Schedule We can initiate our field operations within 5 to 7 working days following authorization to proceed, if site access and weather conditions permit. We anticipate that it will take 1 day to complete our drilling activities. We anticipate completion of our services and submittal of our final report within about 3 to 4 weeks following completion of our field services. In situations where information is needed prior to submittal of our report.we can provide verbal information or recommendations for specific project requirements after we have completed our field and laboratory programs. Acceptance it The work will be performed under the client's "Agreement of Consulting Services"which will be signed once the budget estimate is accepted..

Phase I ESA will be conducted in general accordance with latest ASTM El 527. The project site is approximately 120 acres tract in City of Pearland,Texas. The site is bounded by E. Broadway Street to the north, Old Alvin Road to the east, Mary's Creek to the south and S. Main Street to the west. It is our understanding that the City is considering the south portion of the project site for construction of a regional detention basin. Since the project is preliminary stage,the location and size of the detention basin are not known at this time. 1 a Purpose and Scope The purpose of this ESA is to identify and document any known or potential sources of environmental contamination and Recognized Environmental Conditions (RECs) on or around the project site. The scope of this study will include: 1. Review regulatory agency lists for records regarding possible hazardous material handling, spills, storage and production at the site or in the vicinity that may potentially threaten the subject property. These lists include: CERCLIS,RCRIS, NPL,ERNS,PST,LPST,superfund sites and waste disposal sites. 2. Review selected aerial photography for the past use activity in the site from the 1950's (or whatever available) to present to identify any signs of potential environmental contamination. 3. Review of presence of wetlands and endangered species within the project area. 4. Review .additional records such as topographic maps, Sanborn maps, city directories and fire insurance maps. 5. Perform limited reconnaissance of site and surrounding areas and on-site interviews to identify any indications of potential environmental contamination. • Mr.Alejandro C.Flores,P.E.,D.WRE,CFM Proposal No. 1130031499 Page 2 August 7,2014 6. Prepare a Phase I Environmental Site Assessmen I report describing the findings of this study. Project Schedule We will be able to begin our study within one week upon receipt of your written authorization. The final report including 2 hard copies and 1 searchable soft copy will be submitted in about 8 weeks after receiving your notice to proceed. Fee Based on the scope of work outlined above,the fee of preparing and submitting Phase I i ESA report will be a cost not to exceed amount of$7,308.00. This cost includes "Single Site" Study for the project area. The cost breakdown is shown on Attachment No. 1. We appreciate the opportunity to propose on this project. We hope that this proposal meets your approval. If you have any questions, please call us.
