Page 2 Project Summary The City of Pasadena is proposing to develop a detention pond in order to satisfy an interlocal agreement between the City of Pasadena and the City of La Porte. The agreement between the cities involved the City of La Porte receiving a 99-acre tract from the City of Pasadena in exchange for a 73-acre tract. The City of Pasadena proposed drainage improvements within the 99-acre tract as a part of a planned redevelopment of the Pasadena Convention Center and Fairgrounds site, including the construction of a detention pond with a minimum of 100-acre feet of volume, as well as relocation of several driveways. capacity provisions. The tract is mostly undeveloped and consists of grassy terrain. The proposed project, consisting of a single pond located along the southern portion of the tract, overlaps approximately 6.9 acres of potentially jurisdictional forested wetlands. The goal of the hydrologic and hydraulic analysis was to show no adverse impact on the existing floodplain as a result of the proposed detention pond. Detention Summary The following table identifies the detention summary provided within the report: Floodplain Related Information According to FEMA FIRM Panel No. 48201C0940M, effective June 9, 2014, majority of the 100- year floodplain (Zone AE) to be contained within the channel except for small portions that extend over the west and east overbanks near the downstream side of the project area. The 500-year floodplain (Shaded Zone X) covers approximately half of the project area and generally coincides with the potentially jurisdictional wetlands submitted under an AJD to the USACE for evaluation. Work in the effective FEMA floodway is not proposed in this project. Please also note that the City of Pasadena is the Floodplain Administrator for the receiving waterways. All issues regarding local floodplain regulations must be coordinated through the City of Pasadena. January 6, 2023 Andrew Moore, P.E. Halff Associates, Inc. Page 3 Report Findings The proposed project will cause no adverse impact within the study limit for storm events up to and including the FEMA effective 0.2% chance exceedance event. Hydrologic & Hydraulic Technical Review HCFCD offers the following: 1. The weir side slope shown in the detention summary table is 4:1. Side slopes of overflow weir shall be 5:1 or flatter per Section 13.2 (Exhibit 13-1) of the HCFCD PCPM. 2. Please include 10- and 50-year events in the WSEL comparison in Table 7 or provide a WSEL comparison table for all storm events analyzed in the hydraulic modeling results in Appendix E to demonstrate no adverse impact. 3. Although the report included the future improvement plans proposed by the City of La Porte, the report should clearly state in the executive summary that more detailed analysis with supporting data for the future roadway, bridges and other drainage improvements will be required to submit to HCFCD for review and approval. 4. -3 do not appear correct. 5. Explicitly state who will maintain the proposed detention pond. Additional HCFCD Criteria An additional 40 feet of drainage right-of-way is needed along B112-00-00 for future widening of the channel. Platting is the usual occasion for easement dedication. Easements can also be conveyed to HCFCD by a separate instrument recorded in the Harris County Deed Records. Site plans must be submitted to HCFCD for review and signature. All work proposed within existing and future HCFCD right-of-way must be designed and constructed in accordance with the HCFCD Policy, Criteria, and Procedure Manual. Environmental Review & Permitting proposed projects impacting regulated waters of the U.S. obtain and document the required U.S. Army Corps of Engineers permit(s) for any portions of the project located within any existing or proposed HCFCD right-of-way. The type of permit required (if any) must be stated on the site plans even if written permit authorization from the Corps of Engineers is not required. If written permit authorization is required, copies of approved Corps of Engineers permits must be submitted with the HCFCD Notification of Construction in Right-of-Way and submitted to the HCFCD Development Coordination and Inspection Department at least 48 hours prior to construction along with the 48-hour Pre-Construction Notification.
