A collapsed spillway connected to a pond in the Bella Charca neighborhood in Nolanville remains unfixed after residents of a nearby mobile home community said they addressed the issue with the city following steady rains in April.
Luann Lobato, the manager of Pecan Village Mobile Home Community, said she notified the city and Public Works Director Chris Atkinson that the spillway on the northern end of the pond that runs under Bluebonnet Lane had fallen apart following heavy storms April 11 that eroded the embankment.
But Atkinson told the Herald on Tuesday he had not made aware of the issue by residents.
“First I’ve heard of it,” he said.
The Bella Charca pond feeds into a wildlife area running to the west of the mobile home community and into South Nolan Creek to the north.
“When it gets a lot of rain here, the water rushes right down behind us,” Lobato said.
Lobato, a 32-year employee of the community, said she had never seen the water from the pond overtop the road or flood the western edge of the community.
Pecan Village contains approximately 80 homes on Morningside Drive and Sunset Avenue.
On Wednesday, Atkinson said he inspected the site and determined possible flood water overtopping Bluebonnet Road compromised the concrete spillway on the far side and eroded a stretch of the dam’s embankment.
If unaddressed, the erosion could have permanently damaged Bluebonnet Lane, which is the only road in and out of the mobile home community.
“Since that hadn’t happened in my time here, and I wasn’t made aware to address that area, we could have fixed it earlier had I been aware of it,” said Atkinson, who has worked with the city for approximately two and a half years.
Atkinson estimated the dam was installed in 2004 but did not have an estimate for how much water the pond could hold.
The public works department will seek bids for erosion repair and closely monitor the area in the event of future flooding, Atkinson said.
Glen Colby, manager for the Bella Charca Home Owner’s Association, said the association had not been made aware of the erosion and did not perform maintenance on the northern boundary of the constant-level pond or the spillway on the far side of the road.
“That’s not our property, and we don’t maintain that,” he said.
Colby said association dues pay for maintenance and upkeep for the pond but not the road or spillway infrastructure.
According to the Federal Emergency Management Agency’s online flood map, the pond and tributary running north into South Nolan Creek are not listed as primary floodways or at risk in the event of a significant rainfall event.
The northernmost homes in Pecan Village bordering the creek are in the database’s 100- and 500-year flood zones, indicating a 1- and 0.2-percent annual chance of flood waters from South Nolan Creek reaching those homes.
