SAN ANGELO, TX – San Angelo city council members Tuesday awarded a bid to Darnell Construction to build a stormwater detention basin to alleviate flooding on Ave. P in southeast San Angelo.
As we reported earlier, city engineers plan to build a detention pond on the vacant lots that could hold the stormwater produced by a 25-year rainstorm – a storm capable of producing 5.25 inches of rain over a 24-hour span. The pond, which should be completed in about a year, will prevent stormwaters from rushing down Avenue P and flooding homes along the street.
After the pond is built, city engineers will look to reshape Avenue P to keep floodwaters in the middle of the roadway rather than draining outward toward homes.
An additional feature to be enacted in conjunction with the ponds was to shape the roadway of Avenue P in a “V,” called an “inverted” roadway. This allows Avenue P to act as a conduit for a larger volume of water, keeping most of the drainage during rainstorms in the street, and not up on the lawns or approaching the housing structures.
The city awarded the bid in the amount of $2,351,118 to alleviate flooding on Ave. P.
