Lee County is seeking a qualified contractor to build the Palm Creek Lower Filter Marsh, a wetland and water-quality improvement project in North Fort Myers, Florida.
- **Buyer:** Lee County Board of County Commissioners, through Lee County Procurement Management.
- **Project scope:** Construct an approximately 8.52-acre filter marsh within a larger site, including clearing and grubbing, excavation of about 46,100 cubic yards, off-site hauling and leveling of excess spoils, access and maintenance surfaces, pathways, plantings, and weir, diversion, and outfall structures. The bid schedule requests one complete-project total.
- **Planting quantities:** Marsh plantings total 13,550 across Zones A–C; upland plantings include 62 trees, 60 shrubs, and 1,675 ground-cover plants; low-maintenance tree islands include 36 shrubs and 125 ground-cover plants. Species, sizes, and zone quantities are itemized below.
- **Notable requirements:** Plant material must meet Florida nursery standards and come from an FDEP-approved local or regional source; substitutions require project engineer approval. The contractor must provide a rubber-tire or rubber-tracked backhoe with a 20- or 24-inch flat-edge bucket, an operator, and two laborers for an estimated four days of gopher tortoise excavation support. Planning assumptions are approximately 30 burrows and 15–20 tortoises; final needs depend on field conditions and permits. The contractor also installs silt fence after relocation. Applicable permits and hauling and site-operation restrictions apply.
- **Named organizations:** Lee County Board of County Commissioners and Lee County Procurement Management are the buyer; Johnson Engineering provided the environmental plan set; Tetra Tech engaged Ardaman & Associates, Inc. for preliminary geotechnical work; and Apex Companies, LLC conducted the updated protected-species survey and is identified for tortoise-permit and relocation activities. **No product OEMs, branded products, or product part numbers are specified.**
- **Other supporting work and permit information:** Attachment materials document preliminary geotechnical exploration, a protected-species survey, and permit items and costs. The County is responsible for tortoise permit application and relocation fees.
- **Schedule:** Construction is anticipated after County approval and issuance of a Notice to Proceed; an anticipated start is in early 2027. No completion date or overall construction duration is stated.
