4 Pre Engineering Executive Summary for Need Area M19 COH WBS No. M Need Area M19 Executive Summary CivilTech Engineering, Inc. was contracted to perform storm water drainage pre engineering services for Need Area M19. This project was authorized in Work Order No. 1 under our Single Phase Professional Engineering Services for Negotiated Work Orders for Storm Water Drainage Pre Engineering Services, City of Houston WBS No. M , Contract Number , Ordinance Number , executed on March 27, This Pre Engineering Report documents infrastructure problems and needs, and develops alternative solutions for infrastructure. A recommended Candidate Project has been identified for programming into the City of Houston Capital Improvement Plan (5+5 CIP). Need Area M19 is located in southeast Houston generally east of Interstate Highway 45 and north of Almeda Genoa Road. Need Area M19 is located in the Edgebrook Area Super Neighborhood (Key Maps 576F, K) in City Council District E. The need area encompasses the Gulfway Terrace Subdivision north of Hartsook Street and commercial and open areas. The Gulfway Terrace Subdivision is a single family residential development built in the 1960s. There are approximately 493 single family residential lots in the need area. The subdivision is served by standard two lane concrete residential streets with underground storm sewer drainage systems. The commercial areas south of Hartsook Street are served by two lane asphalt roadway with road side ditches along Frey Road. A small portion of the need area is located in the regulatory 1% (100 year) exceedance probability floodplain associated with Berry Bayou, HCFCD Unit C Berry Bayou, HCFCD Unit C , is a tributary of Sims Bayou, HCFCD Unit C The adequacy and deficiencies of the existing infrastructure systems were evaluated in the need area. The existing infrastructure systems include (1) external drainage systems, (2) storm drainage systems, (3) streets, (4) water lines and (5) wastewater lines. System deficiencies were found in all the infrastructure systems except the streets and water lines. There is only 1 property located in the FEMA regulatory 1% (100 year) floodplain in the need area. There are only 2 FEMA repetitive flood loss properties that have made flood insurance claims in the need area. There have been numerous citizen complaints associated with street flooding. Flooding is attributed to out of bank flooding from Berry Bayou, HCFCD Unit C , and excessive stormwater ponding from inadequate combined street and storm sewer drainage systems in the need area. Water line deficiencies include some lines made of asbestos concrete. Wastewater deficiencies include back of lot sanitary sewer lines with over 64 complaints related to odor, overflows and blockages. Pre engineering involves developing solutions to address the infrastructure problems and needs. Solutions have been formulated to address the storm water drainage problems and needs but a developed Project considers all infrastructure needs. Even though streets were not found deficient, replacement of storm drainage systems will require street replacement. The City has reviewed the inadequate waterline information provided by CivilTech and has not proposed any replacements. Two (2) project alternatives and combinations thereof were developed which included replacement of existing storm drainage system, CivilTech Engineering, Inc. 1 of 3

5 Pre Engineering Executive Summary for Need Area M19 COH WBS No. M streets, and wastewater systems for the need area. Detention mitigation will be required for both project alternatives. The City intends to prioritize Candidate Projects citywide for programming into the CIP. The City has developed the Candidate Project Priority Score, which is a calculated score associated with the service (need) area. The Recommended Candidate Project for Need Area M19 is Project Alternative 2 (Detention Option B). Project Alternative 2 (Detention Option B) achieves the least cost of 27,332,909 and the highest Candidate Project Priority Score of as compared with the other project alternatives. Detention mitigation (Detention Option B) is recommended since the proposed Regional Detention Pond can be located in a government owned tract of land adjacent to Berry Bayou, HCFC Unit C , and may be expanded to provide flood relief along the channel. Each project alternative was divided into subprojects to manage the project costs. The Project Alternatives and Recommended Candidate Project are summarized in the table below: CivilTech Engineering, Inc. 2 of 3

If the land for the proposed Regional Detention Pond cannot be acquired for the recommended Candidate Project, it is recommended that Project Alternative 2 (Detention option A) be selected for in line detention as an alternate Candidate Project. Project Alternative 2 (Detention Option A) has a cost of 27,655,543 and a Candidate Project Priority Score of CivilTech Engineering, Inc. 3 of 3
