What does JRH Engineering & Environmental Services do in Florida?

JRH Engineering & Environmental Services provides civil and structural engineering design solutions for land development and infrastructure projects throughout Florida. Our work includes subdivision street networks, drainage and stormwater systems, and related structural elements for private developers, builders, and public agencies in markets such as Orlando, Tampa, Miami, and the Panhandle.

What changed in the 2026 FDOT Roadway Design Manual and Florida Design Manual?

For 2026 projects, FDOT updated both the Roadway Design Manual and the Florida Design Manual (FDM) with stronger guidance on geometric design, drainage, and context‑sensitive solutions. Key revisions affect subdivision streets that tie into FDOT facilities, intersection design in high‑growth urban and suburban areas, and how drainage and stormwater systems are evaluated for resilience in Florida’s coastal and inland environments.

How do the Chapter 4 drainage and resilient design updates affect subdivision projects?

The updated Chapter 4 criteria place more emphasis on hurricane‑resilient drainage and flood performance for both coastal and inland sites. Developers must account for revised cross‑drainage, outfall, and ponding requirements, and demonstrate that subdivision streets and stormwater systems function properly when they connect to FDOT facilities, which can influence grading, pipe sizing, and pond or outfall locations on your site plans.

What did FDOT change for intersections in Chapter 5?

Chapter 5 now reflects updated intersection design criteria for both high‑speed corridors and dense urban streets, with a stronger focus on safety and multimodal access. The guidance increases expectations for pedestrian and bicycle accommodations and adds enhanced safety features for vulnerable road users in growing cities such as Orlando, Tampa, and Miami, which can affect turn lanes, crossing locations, and signal or control strategies at subdivision entrances.

When should Florida projects consider roundabouts and alternative intersections under Chapter 6?

The revised Chapter 6 expands guidance on roundabouts and other innovative intersection forms and explains why they are increasingly favored in fast‑growing suburban corridors, especially around Orlando and Tampa. These designs can improve safety, reduce delay, and smooth traffic flow compared with conventional stop‑controlled or signalized intersections when they are correctly matched to traffic volumes, speeds, and surrounding land uses.

How does JRH help Florida developers and contractors stay compliant with the new FDOT standards?

JRH uses a low‑overhead delivery model to produce fast, buildable designs that align with the latest FDOT roadway, intersection, and drainage requirements. Our team tracks changes in the Roadway Design Manual and Florida Design Manual and coordinates directly with FDOT district staff so subdivision and roadway improvement projects move through design and permitting efficiently, with fewer revisions and better schedule control.

What types of Florida projects are the best fit for JRH under the 2026 FDOT updates?

JRH is a strong fit for developers, contractors, and municipalities planning new subdivisions, roadway improvements, intersection upgrades, or drainage and stormwater projects that must meet the 2026 FDOT standards. Typical projects include subdivision streets tying into FDOT‑maintained routes, entrance intersections and turn lanes, capacity or safety improvements along state corridors, and resiliency‑focused drainage upgrades in coastal and high‑growth inland areas.

How can I get a quick review of how the 2026 FDOT updates affect my Florida project?

If you are planning a subdivision or roadway improvement in Florida, JRH offers a complimentary 15‑minute review to highlight how the 2026 FDOT updates could affect your design, schedule, and permitting path. You can get started by replying “FDOT” through the JRH website contact options or by calling 800-227-9635 during business hours to speak with our engineering team.
