Tallahassee Yard Drainage Yard Drainage in Crawfordville, FL

Wakulla County, not Leon County

Crawfordville is the Wakulla County seat, and drainage work that connects to a roadside ditch, a culvert or anything else in the right of way is reviewed under Wakulla County's land development regulations rather than Leon County's or the City of Tallahassee's. Work that stays entirely on the property and discharges on the property is generally a different matter, as it is anywhere.

The practical effect is on scheduling rather than on the engineering. The plan is the same plan; the question of who signs off on the outlet, and how long that takes, is answered at the start rather than assumed from how the last job in Leon County went.

Where the clay gives way to sand

Tallahassee sits in the Red Hills, where dense clay under the topsoil is the usual reason water will not drain. Twenty miles south, the ground is changing character into the sandier, limestone influenced country of the Woodville Karst Plain, which drains very differently. Crawfordville sits near that transition.

That makes the percolation test worth more here than almost anywhere else in the service area. Two properties a few miles apart around Crawfordville can genuinely need different solutions, and a plan carried over from a job in town can be aimed at the wrong problem entirely.

Proximity to the Wakulla River and its spring system also means a naturally high water table on some parcels, at least seasonally. Where that is the case it changes what a drain can achieve, because the water is coming up as well as falling down.

What the work looks like out here

Crawfordville has taken a good share of the growth out of Tallahassee over the last couple of decades, which means the housing divides roughly into two. There are the older, larger rural parcels, often on septic and sometimes on a well, and there are the newer subdivisions built on what was pine plantation not very long ago. The drainage problems on those two are not the same problem.

On the newer lots the recurring story is construction: ground compacted by equipment, a final grade that satisfies inspection without giving water anywhere to go once it is clear of the house, and downspouts still discharging onto splash blocks a foot from the slab. On the older parcels it is more often that the original drainage pattern of the land has been interrupted by something, a new driveway, an outbuilding, a filled low spot, and the water is now arriving somewhere it never used to.

Septic is the practical constraint that comes up most often here. A drain field cannot be saturated by redirected water without causing a far more expensive problem than the one being solved, so locating it is part of the site visit rather than something to find out about during excavation.
