How It Works
From initial assessment to permit-ready plans in Longwood.
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.
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.
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.
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.
Local Requirements for Residential Drainage Design
Why Longwood Properties Need Residential Drainage Design
Seminole County's established suburban communities — built in the 1970s-1990s — frequently have undersized stormwater infrastructure that causes flooding in yards and streets during heavy rain. Properties in Altamonte Springs, Casselberry, and Oviedo need retrofit drainage solutions that work within the constraints of already-built neighborhoods where space is limited and existing utilities create conflicts.
Local Factors in Longwood
- Aging 1970s-1990s stormwater infrastructure frequently undersized for current conditions
- Retrofit solutions must work within established neighborhood constraints
- St. Johns River tributary flooding creates additional risk for properties near waterways
- Dense suburban development limits infiltration capacity
Seminole County Soil & Drainage Profile
Seminole County features a mix of poorly drained Spodosols in low-lying areas and moderately well-drained sandy soils on ridges. The county's position along St. Johns River tributaries means many properties face both surface water and groundwater flooding challenges.
Seminole County's established suburban communities — many built in the 1970s-1990s — were developed with stormwater infrastructure designed to earlier, less conservative standards. As these systems age and development intensity increases, flooding becomes more frequent. Retrofitting existing drainage to current standards is a growing specialty, requiring creative engineering within the constraints of already-built neighborhoods.
