Residents press county on Treasure Trove stormwater impacts; commissioners seek extension to join petition
Summary
Residents urged Lake County to oppose a Leesburg-permitted subdivision (Treasure Trove), citing repeated flooding in nearby developments; commissioners directed staff to seek an extension from the water management district, consider joining the petition and to provide technical assistance if needed.
Residents of the Treasure Island peninsula told the Lake County Board of County Commissioners on Sept. 2 they are worried that a 110-lot subdivision permitted by the city of Leesburg will worsen persistent flooding on and near County Road 44.
Jeff Erhart, engineering director for Lake County Public Works, summarized the permitting and design: the applicant’s water-management submittal showed pre-development and post-development peak flows that are nearly identical, and engineers proposed a mix of ponds, filters and stormwater-harvesting measures. “The post development flow is 32 and change and the pre development is 33 and change,” Erhart said when explaining the district permit filings and the county’s limited permitting role (driveway and right-of-way connections).
Multiple residents described ongoing flooding problems tied to nearby developments and urged the county to withhold driveway connection permits until right-of-way for future road widening is secured and to join a petition filed with the St. Johns River Water Management District. Ray and other speakers said they have documented sediment and runoff from adjacent projects that they contend have produced repeated flooding of private property.
After hearing residents and staff, the board directed county staff to request an extension of the administrative-review period from the water management district and to prepare to join the residents’ petition if the district grants the extension. If the district does not grant more time, commissioners directed staff to offer technical assistance to the residents who have already filed the petition. The board also asked staff to return with cost estimates for outside consultants and a recommended funding amount for any county assistance.
Next steps: staff will ask the water management district for an extension, develop a petition and, if time is granted, join the administrative review as a party; if an extension is denied, Lake County will provide technical assistance to the petitioners according to available resources and a board-approved funding amount.
