11-Unit Residential Subdivision in Seminole County, FL
Subdivision development in Seminole County requires both technical design and step-by-step coordination through a multilayered entitlement process. RSP Engineers provided full civil engineering for an 11-unit single-family residential subdivision, supporting the client from early design through final engineering approvals.
Project Overview
Location: Seminole County, Florida
Size: 11 residential lots
Use: Single-family residential subdivision
Scope: Civil engineering, stormwater plans, water/sewer design, and full permitting coordination
What We Delivered
RSP Engineers provided full design and permitting services to bring this residential site through the subdivision process and into construction readiness.
| Plan | Purpose |
|---|---|
| Subdivision Plan | Layout of residential lots, internal roadway, and access points |
| Stormwater Drainage Plan | System to collect and treat runoff in compliance with SJRWMD criteria |
| Stormwater Details | Design of pond, control structures, and overflow systems |
| Water & Sewer Plan | Design of potable water lines, sewer connections, and utility stubs for each lot |
| Construction Notes and Specs | Permit-ready documents for contractors and reviewers |
Environmental and Regulatory Coordination
Stormwater Management: Designed treatment systems that comply with SJRWMD ERP requirements for small residential subdivisions
Wetland Coordination: Addressed potential impacts with mitigation strategy where needed
Utility Review: Evaluated capacity and coordinated with municipal utility providers for service confirmation
Floodplain & Soil Review: Ensured site grading was compatible with FEMA flood maps and suitable soils
Permitting Strategy
The project required a three-step entitlement process with Seminole County and additional regional agency approval. Our team managed:
Seminole County Preliminary Subdivision Approval
Seminole County Final Engineering Submission
Seminole County Final Subdivision Plat
ERP Permit through St. Johns River Water Management District (SJRWMD)
We provided timeline management and agency coordination to maintain approval momentum.
Project Challenges
Multi-Jurisdictional Review: Involved County and SJRWMD, each with distinct submission and review criteria
Wetland Constraints: Required careful layout and drainage planning to avoid unnecessary impacts
Utility Design: Infrastructure had to be balanced with roadway geometry and existing service availability
Project Value
RSP Engineers delivered a complete civil engineering package that:
Met all subdivision and stormwater permitting requirements
Coordinated across County and SJRWMD reviewers
Allowed the client to move confidently to construction
Reduced project delays through effective pre-coordination
Why It Matters
Subdivision development in Florida—especially in Seminole County—demands more than drafting plans. It requires civil engineers who understand stormwater plans, residential infrastructure, and regional permitting. Our team ensured that every component, from lot layout to ERP coordination, was handled strategically and efficiently.
