We have not visited the project site to confirm the information provided. Aspects of the project, undefined or assumed, are highlighted as shown below. We request the design team verify this information prior to our initiation of field exploration activities. Site Location and Anticipated Conditions Item Description The project sites are located at Bill Witt, Lyndale, and Salinas Park in Parcel Information Corpus Christi, Texas. (See Exhibit D) Existing Improvements Bare soil and grass Current Ground Cover Bare soil, grass. Existing Topography Relatively flat(assumed). Site Access We expect the sites, and all exploration locations, are accessible with our truck-mounted drilling equipment. Planned Construction Item Description Information Provided We have been provided site plans for the project. Splash pads shall be approximately 1,000 square feet to 2,000 square feet Proposed Development of wetted surface along with tables, benches and a minimum of two sail type shaded structures to cover both the wetted surface and seating areas.

These services are described in the following sections. Field Exploration Based on our experience of the project site, the following field exploration is planned: Number of Borings Planned Boring Depth (feet) I Planned Location 2 10 Bill Witt Park 2 10 Lyndale Park 2 10 Salinas Park 1 Below ground surface Boring Layout and Elevations: We use handheld GPS equipment to locate borings with an estimated horizontal accuracy of+/-15 feet. Field measurements from existing site features may be utilized. If available, approximate elevations are obtained by interpolation from a site specific, surveyed topographic map. Subsurface Exploration Procedures: We advance soil borings with a truck-mounted drill rig using continuous flight augers (solid stem and/or hollow stem, as necessary, depending on soil conditions). Five samples are obtained in the upper 10 feet of each boring and at intervals of 5 feet thereafter. Soil sampling is typically performed using thin-wall tube and/or split-barrel sampling procedures. In the thin-walled tube sampling procedure, a thin-walled, seamless steel tube with a sharp cutting edge is pushed hydraulically into the soil to obtain a relatively undisturbed sample. In the split barrel sampling procedure, a standard 2-inch outer diameter split barrel sampling spoon is driven into the ground by a 140-pound automatic hammer falling a distance of 30 inches. The number of blows required to advance the sampling spoon the last 12 inches of a normal 18-inch penetration is recorded as the Standard Penetration Test (SPT) resistance value. The SPT resistance values, also referred to as N-values, are indicated on the boring logs at the test depths. The samples are placed in appropriate containers, taken to our soil laboratory for testing, and classified by a geotechnical engineer. In addition,we observe and record groundwater levels during drilling and sampling. Our exploration team prepares field boring logs as part of standard drilling operations including sampling depths, penetration distances, and other relevant sampling information. Field logs include visual classifications of materials encountered during drilling, and our interpretation of subsurface conditions between samples. Final boring logs, prepared from field logs, represent the geotechnical engineer's interpretation, and include modifications based on observations and laboratory tests.

Pavements are patched with cold-mix asphalt and/or ready mixed concrete, as appropriate. Our services do not include repair of the site beyond backfilling our boreholes, and cold patching existing pavements. Excess auger cuttings are dispersed in the general vicinity of the borehole. Because backfill material often settles below the surface after a period, we recommend boreholes are checked periodically and backfilled, if necessary. We can provide this service, or grout the boreholes for additional fees, at your request. Laboratory Testing The samples will be tested in our laboratory to determine physical engineering characteristics. An experienced geotechnical engineer will review the field boring logs and samples. Laboratory tests will be conducted on representative samples to evaluate the pertinent engineering properties of the materials encountered. The laboratory testing is planned to include, but not limit to, visual classification, water content, Atterberg limits and strength tests (unconfined compression/calibrated penetrometer) as appropriate. All of the laboratory tests will be performed in accordance with applicable ASTM standards. Our laboratory testing program often includes examination of soil samples by an engineer. Based on the material's texture and plasticity, we describe and classify soil samples in accordance with the Unified Soil Classification System (USCS). Safety Private utilities should be marked by the owner/client prior to commencement of field exploration. Terracon will not be responsible for damage to private utilities that are not made aware to us. If the owner/client is not able to accurately locate private utilities, Terracon can assist the owner/client by coordinating or subcontracting with a private utility locating services. Fees associated with the additional services are not included in our current scope of services and will be forwarded to our client for approval prior to initiating. The detection of underground utilities is dependent upon the composition and construction of the utility line; some utilities are comprised of non-electrically conductive materials and may not be readily detected. The use of a private utility locate service would not relieve the owner of their responsibilities in identifying private underground utilities. Site Access: Terracon must be granted access to the site by the property owner. By acceptance of this proposal, without information to the contrary, we consider this as authorization to access the property for conducting field exploration in accordance with the scope of services. Engineering and Project Delivery Results of our field and laboratory programs are evaluated by a professional engineer.

Unless instructed otherwise, we will submit our invoice(s) to the address shown at the beginning of this proposal. If conditions are encountered that require scope of services revisions and/or result in higher fees, we will contact you for approval, prior to initiating services.
