Background Information:
The objective of the Purgatory Creek Improvement project is to reduce flooding along Purgatory from the San Marcos River to the discharge from the NRCS Flood Control Dam #5 at Wonder World Drive. Due to the extent of the work, multiple projects will be constructed beginning at the San Marcos River and working upstream. The Purgatory Creek Improvement Project Phase I project limits will be from the San Marcos River to Johnson Avenue and the Phase 2 project limits is from Johnson Avenue to Wonder World Drive.
As part of the project, a permitting pre-application meeting was held on January 22, 2020 to discuss permitting requirements for the Purgatory Creek Improvements project. The meeting was attended by representatives from the US Army Corps of Engineers (UASCE), US Environmental Protection Agency (EPA), Texas Parks and Wildlife Department (TPWD), US Fish and Wildlife Services (USFWS), LAN’s team and City staff. During the meeting, the USACE representative recommended the City consider the Phase 1 and Phase 2 areas as a single project and permit them together.
This change in service for USACE Permitting of the Phase 2 area includes the following:
• Expands the project area to conduct permitting related tasks to include the Phase 1 and 2 areas (San Marcos River to Wonder World Drive).
• Conduct similar services as currently authorized for the Phase 1 area including:
o USACE Section 404 Permit Compliance
o USACE Section 7 Consultation
o USACE Section 106 Permit Compliance
o Compliance with Antiquities Code of Texas
The estimated schedule to complete these USACE Permitting of the Phase 2 area will be completed with the original 30% Design phase (end of 2020).
The project team, led by Lockwood, Andrews & Newnam, Inc. (LAN), completed a Preliminary Engineering report in May 2019. On December 3, 2019, the City authorized LAN to develop 30% design plans for the Phase 1 area (San Marcos River to Jonson Avenue). The project includes channel modifications for flood control, greenway trails for transportation connectivity, water quality, natural stream stability design for erosion prevention, replacement of road crossings, utility modifications, permitting and approval requirements, and construction cost estimates.
