Since no local critcria exists, design criteria for the wet portion of Pond B will be developed by CONSULTANT. taking into account available standards and surrounding conditions. Updated geotcchnical testing will be reviewed by CONSULTANT to determine if a liner is required to maintain a permanent pool in the wet portion of Pond B. First Amendment to the Agreement for Professional Services. Page 5 b. Schematic drabiage s }stem and clwenfio r pomllaroufr. Interim and ultimate pond layouts and associated storm sewer will be developed utilizing design considerations identified during data collection. The interim pond layout will be sized to mitigate only the construction of Baker Road, and will not disturb the existing stock pond in the southwest portion of the property, as directed by City staff. Ultimate pond design will be sized to mitigate the 100•ycar event in the Baker Road Development corridor, as identified in preliminary design submitted in April 2011. The existing stock pond will be integrated into the wet portion of Pond B under ultimate conditions. Pond schematics will be submitted to the OWNER for review. c. Regional cleteutiou po►rd do %vig►r. 1. Limited water availability modeling will be performed on Pond B to determine if sufficient runoff to the pond is anticipated to maintain the permanent pool. If local runoff is not sufficient to maintain the permanent pool, CONSULTANT will also estimate the additional volume of water that will be required to maintain the permanent pool water surface elevation (WSE) within the vet portion of Pond B. The permanent pool WSE must be maintained for the health of adjacent pond vegetation and so that the clay liner (if required) remains intact. CONSULTANT will meet with OWNER'S staff to determine what water sources are available to maintain the permanent pool during dry weather conditions. 2. Hydrologic modeling developed for the dry detention pond preliminary design of Pond B will be modified to simulate the revised wet and dry design. Both interim (to be constructed to mitigate Baker Road only) and final conditions will be simulated to quantify storm water runoff reduction benefits. Results of this analysis will be submitted to the OWNER for review. d. HCFCD Impact Anal yxhr Hydrologic modeling will be finalized for both interim and ultimate conditions. Modeling results will be integrated into an Impact Analysis report to be submitted to both HCFCD and to the OWNER for review.

Site reconnaissance will be conducted on all streets and rights -of -way where proposed drainage activities First Amendment to the Agreement for Professional Services, Page 4 are planned. Interviews will be conducted with key site individuals of regulated environmental sites and sites that may store or use potential contaminants. Adjoining properties will be observed for the potential to impact the site and any regulated sites adjacent to the property will be observed. Photographs will be taken during site visit. e. Review of Previous Study. A review of any previous studies that may be available for the site or site area. f. Reporting. Following the review of data, site reconnaissance and data analysis, a report will be prepared summarizing the findings and conclusions. The report will include: a summary of the field observation data; figures and/or drawings depicting general, environmental, and geologic conditions; a review for the potential for contamination to impact the site; and recommendations for further environmental studies (if necessary). 2. Revised Design for Pond B. Modify the dry detention pond preliminary design of Pond B to include wet and dry components as well as site considerations for future park amenities. The layout of the wet and dry components will follow the general schematic outlined by OWNER'S staff in meetings on April 29, 2011, and on July 7, 2011, as part of the City's review and evaluation of the Preliminary Design Phase. Although CONSULTANT will not design park amenities, the pond grading will provide. space for future park amenities, such as soccer fields, for future development by others. The OWNER will provide the size and location of anticipated future amenities. CONSULTANT will develop a set of preliminary PS&E documents and drainage calculations to be reviewed by OWNER. Once OWNER review comments are addressed, CONSULTANT will integrate the proposed Pond B design into final design documents as outlined in the original contract scope for the Final Design Phase. Design work for the revised design of Pond B will include: a. Data collection 1. CONSULTANT will meet with OWNER'S Engineering and Parks staff to determine overall design considerations such as sidesiope grading, placement of future park amenities, placement of future parking, pond maintenance considerations, and vegetation requirements for the pond. 2. Since no local criteria exists, design criteria for the wet portion of Pond B will be developed by CONSULTANT, taking into account available standards and surrounding conditions. Updated geotechnical testing will be reviewed by CONSULTANT to determine if a liner is required to maintain a permanent pool in the wet portion of Pond B. First Amendment to the Agreement for Professional Services, Page 5 b. Schematic drainage system and detention pond layouts. Interim and ultimate pond layouts and associated storm sewer will be developed utilizing design considerations identified during data collection. The interim pond layout will be sized to mitigate only the construction of Baker Road, and will not disturb the existing stock pond in the southwest portion of the property, as directed by City staff. Ultimate pond design will be sized to mitigate the 100-year event in the Baker Road Development corridor, as identified in preliminary design submitted in April 2011. The existing stock pond will be integrated into the wet portion of Pond B under ultimate conditions. Pond schematics will be submitted to the OWNER for review. c. Regional detention pond design. 1. Limited water availability modeling will be performed on Pond B to determine if sufficient runoff to the pond is anticipated to maintain the permanent pool. If local runoff is not sufficient to maintain the permanent pool, CONSULTANT will also estimate the additional volume of water that will be required to maintain the permanent pool water surface elevation (WSE) within the wet portion of Pond B. The permanent pool WSE must be maintained for the health of adjacent pond vegetation and so that the clay liner (if required) remains intact. CONSULTANT will meet with OWNER'S staff to determine what water sources are available to maintain the permanent pool during dry weather conditions. 2. Hydrologic modeling developed for the dry detention pond preliminary design of Pond B will be modified to simulate the revised wet and dry design. Both interim (to be constructed to mitigate Baker Road only) and final conditions will be simulated to quantify storm water runoff reduction benefits. Results of this analysis will be submitted to the OWNER for review. d. HCFCD Impact Analysis Hydrologic modeling will be finalized for both interim and ultimate conditions. Modeling results will be integrated into an Impact Analysis report to be submitted to both HCFCD and to the OWNER for review. CONSULTANT will address HCFCD comments and modify the design of outfall structures as necessary. e. Preliminary plan production The following construction documents will be revised as necessary for the Pond B design: 1. Summary of Drainage Quantities & Construction Cost Estimate First Amendment to the Agreement for Professional Services, Page 6 2. Proposed Drainage Area Map 3. Runoff Computations 4. Storm Sewer Hydraulic Data (HouStorm) 5. Drainage Plan and Profile (combine with Roadway Plan & Profile) 6. Culvert outfall for conveyance to Q112-03-00 7. Interim Detention Pond Layout & Stage Discharge 8. Interim Detention Pond Sections 9. Extreme Event Overflow Event Structure Detail 10. Outfall Structure Details (Inflow to Detention Pond) 11. Harris County Flood Control and City of Baytown Standard Details 12. Detention Pond and Channel Excavation Earthwork Quantities 3. Supplemental ROW Field Surveying for Ponds A & B CONSULTANT will cause to be performed ROW mapping and surveying services to comply with OWNER'S platting requirements and to support the ROW Acquisition Phase. The work associated with this task will include the following: a. Develop ROW map/plat and metes and bounds description for the site north of proposed Baker Road and east of HCFCD Unit 0105-04-00, identified for Pond A (approximately 7 acres). b. Develop ROW map/plat and metes and bounds description for site south of proposed Baker Road between Barkaloo Road and Crosby -Cedar Bayou Road, identified for Pond B approximately 15 acres). c. Perform coordination and obtain approvals necessary to meet requirements of OWNER'S platting process. 4. Supplemental Topographic and ROW Field Surveying for Foot Path CONSULTANT will cause to be performed topographic and ROW mapping and surveying services to support the coordination and design of a footpath south of Baker Road and east of Barkaloo Road. The work associated with this task will include the following: a. After determining location of proposed foot path, cross section field shots will be taken along the proposed alignment extending approximately 10' either side of the proposed centerline of the foot path. A digital terrain model (DTM) will be developed and incorporated into the existing DTM where appropriate. b.

Supplemental Geotechnical Investigations and Engineering CONSULTANT will cause to be performed geotechnical investigations and engineering for the purpose of evaluating the conditions and parameters related to designing and developing a portion of previously identified Pond B (Cedar Bayou pond/basin) for wet -bottom operating conditions. The specific tasks to be performed as part of this task are as follows: a. Six borings will be drilled to a depth of 30 feet below the existing grade. The borings will be sampled continuously to a depth of 20 feet and then at regular 5-foot intervals thereafter to the termination depth of the borings. The borings will be used to determine the site stratigraphy and to obtain samples for laboratory testing. The laboratory testing program is intended to provide confirmation of the field visual soil classifications and to establish properties of the subsurface materials required for design. All boreholes will be backfilled with soil cuttings and bentonite chips. b. The depth at which ground water is encountered during drilling shall be measured and recorded. The 24-hour ground water levels will also be measured and recorded. c. Two borings will be converted into piezometers to record long- term water level readings. Water readings will be taken three times within a period of one month. d. Possible laboratory tests to be performed for this project include: moisture contents (ASTM D2216); Atterberg limits ASTM D4318); minus No. 200 sieve analysis (ASTM D1140); unconfined compression (ASTM D2166); Unconsolidated Undrained Triaxial (ASTM D2850) and Consolidated Undrained MultiStaged Triaxial (ASTM D 4767) tests with pore pressure measurements and permeability tests. In addition, some samples will be tested for dispersive soils using Pinhole, Crumb and Double Hydrometer tests. The actual type and number of tests to be performed will depend on the soils encountered during the field investigation. e. All the field and laboratory tests will be performed according to ASTM standards, where applicable, or with other established procedures. Results of the field and laboratory data will be used to develop design recommendations for the detention pond. Engineering analyses for the detention pond slope construction will include slope stability by the Bishop Method. Slope stability analyses will be performed for the End of Construction Case, Rapid Drawdown Case and Long -Term Case. Residual strengths of soils will be considered and used in the slope stability analysis for the rapid draw down and long- term cases. First Amendment to the Agreement for Professional Services, Page 8 f. A geotechnical report of the study will be prepared by an engineer specializing in soil mechanics and foundation engineering after reviewing available structural, geological, boring, and laboratory data. In general, the following items will be included in the report: 1. Boring logs and test data, 2. Groundwater conditions, 3. Generalized subsurface conditions, 4. Detention pond slope stability analysis, 5. Dispersive potential of on -site soils, 6. Clay liner design, and 7. Erosion control recommendations g.
