Our Process

How It Works

From initial assessment to permit-ready plans in Sarasota.

1

We visit your property to evaluate existing conditions, identify the source of water problems, assess soil types and permeability, and document elevations and flow patterns. This on-site assessment is the foundation of every successful drainage design.

2

Our survey team collects accurate elevation data, property boundary information, and locations of existing utilities and structures. This data feeds directly into the engineering design to ensure precise grading and pipe sizing.

3

Our Licensed Professional Engineers develop a complete drainage design including pipe sizing calculations, grading plans, detention/retention requirements, and construction details. Every design accounts for Florida's 25-year/24-hour storm event and local code requirements.

4

We prepare and submit all required permit applications to your local building department, SFWMD, or other agencies. Our team manages reviewer communication and addresses any comments to keep your project moving toward approval.

Why Sarasota Properties Need Residential Drainage Design

Sarasota County's Phillippi Creek watershed flooding crisis directly affects residential properties — the creek's sediment-clogged channels and neglected infrastructure cause flooding that extends well beyond the creek's immediate banks into surrounding neighborhoods. Properties in the Phillippi Creek area need drainage solutions that account for the watershed's reduced conveyance capacity and the county's aging berms and levees.

Sarasota County Regulatory Note Sarasota County Public Works reviews drainage permits. SWFWMD Environmental Resource Permits for surface water projects. Phillippi Creek watershed projects may require extended multi-agency review.

Local Factors in Sarasota

  • Phillippi Creek (55 sq mi watershed) suffers from sediment buildup, fallen trees, and unmaintained berms neglected since 1960s agreements — overflows into Colonial Gables and Laurel Meadows during 100-year+ storms
  • Cow Pen Slough berm breach at Rothenbach Park documented failure pattern from 1979-2024 — county neglect allowed berm deterioration that flooded Delft Road homes
  • Phillippi Creek flooding crisis affects residential neighborhoods well beyond the floodplain
  • Aging berms and levees from the 1960s are identified critical vulnerabilities
  • Nearly 25% of flood claims occur outside designated high-risk zones

Sarasota County features poorly drained Spodosols throughout most of the mainland, with the seasonal water table reaching the surface during the wet season. The flat terrain and restricted drainage outfall capacity create chronic flooding conditions that require engineered solutions.

The Phillippi Creek watershed is the epicenter of Sarasota County's drainage crisis. Decades of development along this low-gradient waterway, combined with sediment accumulation and neglected infrastructure, have created chronic flooding conditions that affect thousands of properties. Engineering solutions must address both the immediate flooding (pump stations, channel clearing) and the long-term capacity issues (detention volume, watershed-scale retention).

Local Cost Factors for Residential Drainage Design in Sarasota

Phillippi Creek watershed projects face complex multi-property coordination
Aging infrastructure assessment adds investigation costs before design begins
Pump station design and installation is more expensive than gravity-based drainage
Barrier key properties (Siesta Key) require specialized coastal engineering
Local Infrastructure

Drainage Infrastructure Near Sarasota

Phillippi Creek — Sarasota's largest watershed at 55 square miles; chronic siltation and sedimentation reduce channel capacity
Cow Pen Slough berm/levee system — neglected since 1960s maintenance agreements, documented failures from 1979 through 2024; county repairing with rock after breaches
