This project was originally scoped after Hurricane Harvey, as part of the Hurricane Harvey Long-Term Recovery Plan process. The City of Gregory experiences frequent flooding events, and have several flood zones within their city limits, including a regulatory floodway, which causes the residents to have higher than average flood insurance premiums and damages to their homes and businesses.
With the help of the San Patricio County Drainage District and Hanson Engineering, the County was able to propose a project which would alleviate the flooding within the City of Gregory, and hopefully lessen the impacts from flooding for the residents and businesses. This project includes major renovations and lowering of the Green Lake Dam in Portland, the creation of a diversion ditch to the southwest of Gregory, new culverts under US 181, and the deepening and widening or existing drainage ditches. The Texas Department of Transportation has already added the new culverts under the highway in preparation for this project. San Patricio County entered into an agreement with the Nueces River Authority to act as the Grant Administrator on this project, to utilize their expertise and ensure proper completion of the project.
The Flood Infrastructure Fund awarded the funding for this project via a partial grant, with a zero interest loan. The initial funding of $2,369,990 was awarded as a grant, while the remaining amount of $11,574,130 was awarded as a loan to the San Patricio County Drainage District to be paid out over time.
The long term outcome of this project will be to reduce flooding in the neighborhoods of Gregory, reduce the footprint of the 100 year flood plain, and hopefully eliminate the existing Regulatory Floodway within the city. The residents will see less losses to their property, and eventually lower flood insurance premiums.
