How Does Development Review Work in Unincorporated Florida Counties?

By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15

Unincorporated Florida development goes through the county DRC with concurrency review proving adequate roads, water, sewer, and drainage capacity; engineers front-load traffic, utility, and stormwater analysis since concurrency findings drive approval.

Navigating the DRC cycle

The DRC runs on a fixed calendar — application deadlines, staff review periods, meeting dates — and I plan the project around it from the entitlement schedule's first draft. The pre-application conference is the highest-value meeting in the process: county staff tell you which studies they require, which concurrency methodologies apply, and what the hot-button issues are for your site. I come with a concept plan and specific questions, not a blank slate. The formal submittal then arrives complete: site plans, drainage report, utility plans, traffic study, landscape plans — everything the checklist requires, because a deficient submittal does not get a partial review, it gets deferred to the next cycle.

Concurrency-sensitive engineering

Three engineering workstreams carry concurrency weight and deserve early, careful effort. Traffic: the impact study follows the county's adopted methodology and trip generation rates, and its findings can trigger off-site improvements that reshape the project budget — I get the traffic engineer scoped during due diligence. Utilities: capacity letters from the water and sewer providers confirming adequate supply and treatment capacity at the adopted level of service, secured before the DRC submittal. Drainage: stormwater design meeting both the county's level of service and the water management district's criteria, since a system that passes one and fails the other still fails. These three decide whether the project is approvable; everything else is refinement.

Florida county development review checklist

County development approval in Florida proceeds smoothly when these items are sequenced correctly. The process rewards completeness and punishes partial submittals. • Pre-application conference held; county's required studies and methodologies confirmed • Concurrency-sensitive work (traffic, utility capacity, drainage) completed to county methodology • Water management district environmental resource permit pursued in parallel with DRC • Complete DRC submittal package filed to the county's checklist — no placeholder sheets • Development order conditions tracked into the building permit drawings so nothing is lost between approvals

What else do project teams ask?

What is concurrency in Florida development review?

Concurrency is the state-rooted requirement that public facilities — roads, potable water, sanitary sewer, drainage, parks, solid waste, and schools — have adequate capacity available at the county's adopted level of service when your development's impacts hit. The county measures your project's demand against available capacity; if the system is already at its limit, your project must mitigate (road improvements, for example), wait for planned capacity, or it does not get approved. For engineers, concurrency turns traffic studies, utility demand calculations, and drainage analysis into entitlement documents, not just design documents. I scope them to the county's methodology from the start, because a study the county cannot use is money spent twice.

What is a Development Review Committee (DRC)?

The DRC is the county's interagency review body for development applications — planning, engineering, utilities, fire rescue, environmental, and legal staff reviewing your site plan together and issuing consolidated comments. You typically present or respond at scheduled DRC meetings on a fixed cycle (weekly or biweekly in larger counties). The benefit is one coordinated comment set instead of sequential agency reviews; the discipline it demands is a complete, coordinated submittal, because an incomplete package burns a whole cycle. I use the county's pre-application meeting to learn exactly what the DRC expects before the first formal submittal.

How does the county path differ from developing inside a Florida city?

The structure is similar — site plan review, concurrency, then building permit — but the county process is broader and slower. County DRCs review every project type across the entire unincorporated area, so reviewers are less specialized and cycles run longer than a busy city's development review. Cities often have more staff continuity, meaning you see the same reviewers project after project. The substantive standards can also differ: county stormwater, roadway, and utility criteria reflect rural-to-suburban conditions and water management district rules, while cities layer on urban form standards. I scope schedule and fee to the county's actual cycle times, not the city's.

Do I need water management district approval too?

Very often, yes. Florida's water management districts regulate stormwater management systems, wetland impacts, and water use separately from the county's development review — an environmental resource permit for your stormwater system is a parallel approval with its own application, criteria, and timeline. The county will want to see the district permit (or at least the application underway) before final development approval. I run the district permitting in parallel with the DRC process from the beginning, designing the stormwater system to satisfy both the district's and the county's criteria in one design. Two stormwater designs for one site is the failure mode to avoid.
