Flood Protection Master Plan
Background Information:
In June 2017 City Council approved a list of on-call engineering firms responding to RFP #217-247 for design of the Riverine Project. Three firms from the list were selected for interview on their specific qualifications for the Blanco Riverine (aka Blanco San Marcos Rivers Flood Mitigation) Project. Halff was selected after the interviews based upon their project team and involvement with the GBRA/USACE Flood Mitigation project.
This project is the fifth project approved by City Council for the CDBG-DR infrastructure funding. The scope will begin with the project as envisioned with the CDBG-DR- Feasibility Study and the GBRA/USACE Flood Mitigation Study. A refinement of these two studies will provide a preliminary engineering report (30% design and environmental coordination) for the short term CDBG-DR Blanco Riverine project as approved in Substantial Amendment #4. The preliminary report will consider input from both a public meeting and landowner meetings as well as environmental constraints and benefit/cost. The prioritization matrix developed during the Feasibility Study will be refined for the short term alternatives analysis. Additionally the Preliminary Engineering report will identify long term options to increase the flood protection level through a larger state or federal funded project and through the City’s planning and engineering efforts.
The milestones in this scope are:
Property Owner & Public Listening Mtg - April 2018
Evaluation of alternatives, follow-up public mtg and City Council direction - August 2018
Schematic design, environmental assessment, agency coordination, clearance - August 2019
The loan proceeds from the Texas Water Development Board loan will be used to fund this preliminary phase. After the preliminary phase is approved and environmentally cleared, the design scope will be finalized and will be potentially funded from either TWDB or CDBG-DR funds. Using the $1,921,000 in TWDB funds for as much of the design and land acquisition costs as possible will allow the CDBG-DR funds to be allocated to construction. Based upon the proposed schedule, construction should begin late 2020.
