County postpones Mountain Lake Drive rezoning after questions about septic, roads and flood rules

Lake County commissioners postponed a request to rezone roughly 4 acres on Mountain Lake Drive from neighborhood commercial and agriculture to urban residential (R-6) after commissioners and residents raised questions about wastewater systems, road requirements and floodplain rules.

Staff said the applicant proposes single-family housing with lots larger than the original 1926 plat and that the concept proposes about 2.25 dwelling units per net acre, below the R-6 maximum of 5.5 dwelling units per net acre. Planning staff also said development would rely on private wells and septic systems and that transportation concurrency could not be determined until specific uses are identified.

Commissioners and residents pressed staff about whether distributor wastewater treatment systems (DWTS) would be required in the Wekiva protection/study area and about Department of Health minimum lot-size standards. A staff exchange in the meeting noted that current code does not automatically require DWTS for straight rezonings (the county has used DWTS requirements in conditional zonings) but that an ordinance change could be drafted to require DWTS in certain areas. The Department of Health’s current minimum lot-size standard cited at the hearing was 21,780 square feet; older county lot-of-record rules referenced 12,500 square feet.

Staff also said the road shown on the concept plan is platted as public right-of-way but is not built; the property owner would have to construct a county-standard roadway if lots were platted. One commissioner requested an ordinance change to make DWTS mandatory where feasible; staff offered to prepare an ordinance if the board directed it.

The board postponed the rezoning to the next zoning meeting to allow staff time to clarify DWTS and floodplain issues, and to give the applicant a chance to respond; the motion to postpone was approved by the board.
