Applying the New Stormwater Rule: Compliance Tips and Expert Insight

Upcoming Webinar: New Stormwater Rule – What You Need to Know

Live from Environmental Permitting Summer School in Marco Island, join Mark Thomasson, P.E., former Director of the Division of Water Resource Management at FDEP, for a deep dive into Florida’s updated stormwater rule. Learn what the changes mean for your projects and how to stay compliant under the new requirements.

Date: July 15 | Time: 11 AM–12 PM

Florida-licensed Professional Engineers will receive 1 complimentary Professional Development Hour (PDH) credit for attending the live event.

Live Panel Discussion at Environmental Permitting Summer School

Mark will also be facilitating the panel, From Rule to Reality: Implementing Florida’s New Stormwater Standards. With some provisions of the 2024 rule already in effect and others delayed until late 2025, the panel will explore how the rule is being applied in practice and what engineers, developers, and local governments should expect next.

The discussion will cover how the rule is being applied in practice, upcoming changes, and strategies for preparing now. The session will include real project examples and time for audience questions.

Wednesday, July 17, 3:30–5:10 PM: Caxambas 1–2
Friday, July 19, 8:30–10:10 AM: Calusa 8–9

If you’ll be attending Environmental Permitting Summer School, we hope to see you there!

Engineering Guidance: Estimating O&M Costs

As of June 28, 2024, Florida’s updated stormwater rule requires permit applicants to submit a cost estimate for the perpetual operation and maintenance (O&M) of stormwater systems. This estimate must include current-dollar values for annual expenses and planned replacements based on service life. Applicants must also demonstrate financial capability by submitting Form 62-330.301 (26).

Estimating life-cycle costs can be complex, especially when systems include BMPs with varying service lives. To support applicants, the Florida Stormwater Association Educational Foundation—alongside FDEP and the Water Management Districts—offers a BMP Life-Cycle Costing Tool. This resource provides guidance on cost calculations, discount rates, and recommended maintenance tasks for a range of BMPs.
