City of Pearland 3523 Liberty Pearland, Texas 77546 Re: June 2001 Pearland Flooding Dear Mr. Hargrove: Klotz Associates, Inc. appreciates the oppommity to present this scope of work to the City of Pearland. This scope of work includes our understanding of the work elements associated with evaluating and documenting the rainfall and flooding that occurred in Pearland the week of June 4, 2001 through Sunday June 10, 2001. According to your preliminary numbers, several hundred homes flooded as part of Tropical Storm Allison. The flooding was associated with drainage areas or structures on Mary's Creek watershed and along the Pearland side of the Clear Creek watershed. Because Hickory Slough is located between Clear Creek and Mary's Creek and is a tributary to Clear Creek, we have also included it on the scope of work, but is not a large part of this scope of work. This scope of services is based on our meeting at your office on Friday June 15, 2001. The tasks that will be performed are summarized below: Data Collection and Coordination 1. Meet with City staff to discuss Tropical Storm Allison flooding issues. 2. Coordinate with City staff to obtain available data, topographic data, previous studies, plans for selected areas, and information on flooding problem areas. This coordination will include contacting Larry Stead, Lewis Robinson, Bobby Whisenaut, Cecil Bowery, Charlie Stubbs, C.R. Long and John Hargrove. It is anticipated that this coordination effort will involve field visits with some of these City staff members. 3. Obtain available rainfall gage data from the Clear Creek, Hickory Slough, and Mary's Creek watersheds. Such data will include precipitation rates, channel stage records, channel flowrates, and high-water marks from various sources, including USGS and Harris County Office of Emergency Management. 4. Perform field reconnaissance to identify location of high-water marks that will be surveyed by our subconsultant. 5. Coordinate with our Surveyor to survey high-water marks. KLOTZ ASSOCIATES, INC. Mr. John Hargrove, P.E. July 3, 2001 Page 2 6. Obtain the computer HEC-1 and HEC-2 or HEC-RAS models for Mary's Creek, Hickory Slough and for Clear Creek from the City of Pearland. 7. Obtain the latest topographic and photographic data from the City. Analysis of Tropical Storm Allison Rainfall Event 1. Model the Tropical Storm Allison precipitation patterns or average rainfall amounts in the HEC-1 models for the Clear Creek, Hickory Slough, and Mary's Creek watersheds. These HEC-1 models will be referred to as the June 2001 Observed Rainfall HEC-1 models. 2. Input flows from the June 2001 Observed Rainfall HEC-1 models into the HEC-2 models for Clear Creek, Hickory Slough, and Mary's Creek watersheds. These HEC-2 models will be referred to as the June 2001 Observed Rainfall HEC-2 models. 3. Determine the probable return periods along the Clear Creek, Hickory Slough, and Mary's Creek channels. Data from the June 2001 Observed Rainfall HEC-1 models and the June 2001 Observed Rainfall HEC-2 models will be compared to the FEMA FIS report data to determine the return periods. Map Floodplains on the City of Pearland's Topographic DTM 1. Map the floodplain, based on the June 2001 Observed Rainfall HEC-2 models. 2. Map the floodplain, based on the surveyed high-water marks and other available flooding information. 3. Map the 10-, 50-, 100- and 500-yr FEMA floodplain water surface elevations (from the published FIS) into the City of Pearland's topographic DTM. 4. Map the 100-yr floodplain from the City ofPearland HEC-2 models for the Clear Creek, Hickory Slough, and Mary's Creek watersheds. Document Findings and Conclusions in Report 1. Document flood frequency retum interval of June 2001, Tropical Storm Allison. 2. Compare FEMA mapped floodplains to City ofPearland's DTM model. 3. Contrast the Tropical Storm Allison flood plain results to the known (surveyed) high- water marks to generally determine how accurately the current HEC-1 and HEC-2 models reproduce the flooding event. 4. Develop draft report including text, tables and exhibits. 5. Submit eight draft reports the City. 6. Present the draft report to City Council. 7. Solicit and obtain comments to draft report. 8. Finalize report and submit ten copies to the City. K LOTZ ASSOCIATES, INC. Mr. John Hargrove, P.E. July 3, 2001 Page 3 We plan to him a local surveyor, Chuck Davis, to conduct the field surveying of the identified areas to obtain high-water marks. While the more high-water marks we can obtain the better resolution we will have in our floodplain mapping, we believe that we can accomplish this scope with a total of 150 surveyed points. We estimate that once the concurrence on what items to survey is obtained, that it will take two to three weeks to complete the survey data and to receive the survey data at Klotz Associates. As we discussed the surveying will be conducted on a time and material basis. The estimate for the surveying is approximately $16,500. This is a preliminary estimate and we will get a more detailed estimate from the surveyor when we have sufficient data for him to provide a time and material estimate. We estimate that it will take approximately four weeks from receipt of survey data to provide the City with a draft report. We estimate the cost of engineering and report production at $47,600. The combined cost of surveying and engineering is estimated at $64,100. The following assumptions were made in generating this scope of services. Assumptions 1. The City of Pearland's DTM does not require substantial adjustments (more than a day of effort at Klotz Associates). 2. All floodplain maps will be generated and based on the City of Pearland's topographic DTM. 3. All floodplain mapping will be contained within the limits of the City of Pearland's DTM, and will be limited to the City of Pearland's boundaries, and to 288 on the west. 4. It is assumed that a total of 150 surveyed highwater marks will be collected. 5. A total of 8 draft and 10 final reports will be submitted to Pearland. It is assumed that 2 of the draft and all 10 of the final reports will be printed in color. We are ready to mobilize our staff to conduct this documentation and evaluation of the June 2001 flooding event in the City of Pearland. Please contact Gary Bezemek, P.E. or me at 281-589-7257 if you have any questions regarding this proposal and scope. Sinc. erely, . Gary L. ~gtruzick, P.E. Vice President - Chief Engineer GLS:ng C.L.
