Coppell will undergo a feasibility study to figure out how to fix a failed diversion wall the runs through the Grapevine Springs Park canal.
During a recent meeting, the City Council approved a project that would provide the city options on what to do to get water running through the canal once again.
The park is owned by Dallas County and maintained by Coppell. According to a staff memo, in 2015, the city began a project to dredge the park’s canal and repair its walls. In 2016, the diversion wall that routed water from Grapevine Creek through the park’s canal failed, bringing the project to a halt.
“With no water movement, we end up with water quality issues, algae growth and stagnant water,” said John Elias, parks project manager. “... We have a lot of concerns with West Nile, Zika and all of those things that come with stagnant, standing water.”
Elias said when the wall failed, the city looked for an easy, inexpensive fix but failed to find one.
The staff memo says that the failure of the diversion wall and the resulting low water flow through the canal has dramatically changed the park. Officials said the replacement of the failed diversion wall will be significantly more than the $300,000 budget for the original project.
Coppell has asked Dallas County for help with funding a solution. The approved feasibility study will evaluate and recommend a course of action for reconstructing the wall or another way to maintain water flow throughout the canal.
According to Dallas County, Grapevine Springs Park is the one of the most historic preserves in the county’s open space system. In 1936 the area was turned into the park but was closed to the public and privately owned in 1940s. In 1991, it was donated to Dallas County. The county along with Coppell restored the park and opened it back up to the public in 1994.
Elias said the feasibility study will take about six to eight weeks to complete. After the study is conducted, the city staff will review the results and give an update to the council.
