Happy New Year! The new year has brought floods and even snow to the Southeast which goes to show that there really is no “off season” to being prepared and resilient. One of the most effective ways of increasing a community or state’s resiliency is to reflect on previous experiences (they do not necessarily have to be our own) and how we can learn from them to make better decisions for the future. SESWA is a great resource to exchange ideas, learn from others, and collaborate on addressing water quality and flooding in a more comprehensive manner. SESWA’s recent webinar Intersection of Green and Grey Infrastructure and SESWA’s upcoming Seminar are both good opportunities to learn more about others’ experiences to help their communities become more resilient. Registration for the Unprecedented Opportunities for Stormwater Infrastructure Projects Seminar is now open. The single-day event will focus on what is being implemented with the recent influx of funding, while discussing the options for continued investment in infrastructure.

As we look ahead, SESWA’s 2024 Annual Action Plan includes a series of actions to be carried out by the membership. I would like to highlight two initiatives that we will be focusing on in 2024:

  • Using lessons learned, we will be building upon programs that build connections including Service Projects and our new member Ambassador program. This action is more focused on a holistic approach to engaging members in meaningful conversation and service. I have always felt people want to make a difference and as mentioned above, we can make a difference by building and learning from connections we can make through our work on committees, actively participating at conferences (not just attending), etc.

  • SESWA is exploring opportunities to partner with local colleges to recognize and expand the awareness of the stormwater industry. I am so excited (and jealous sometimes) of the energy of our membership to lead and develop future stormwater professionals. This year I’ve added an initiative in the Action Plan to consider a pilot project to do just that. Stay tuned for more details as they are finalized.

As we embark on 2024, I ask that you please think about ways to become informed, committed, and engaged in SESWA’s work. I know you will not regret it!

As a follow up to the SESWA Spring Seminar on resiliency, the Association’s Stormwater Policy Committee is preparing a series of articles focused on different issues related to climate change and stormwater. A total of six articles will be prepared throughout the year, each on different topics. The approach will be to interact with stormwater program managers and other stormwater professionals to get their input on each topic area. The articles will be accompanied by poll questions, Community Forum posts, and LinkedIn notices to gain additional input from the SESWA community. The information gathered will be combined into reference materials that will be shared with SESWA’s membership.

Resiliency: Soft Solutions for Resiliency
Reported by Rob Brown, Goodwyn Mills Cawood
SESWA Stormwater Policy Committee Member

This month, as we continue our dive into resiliency, the focus is “Soft Solutions.” There can be a number of approaches to strengthen preservation ordinances for buffers and floodplains that go beyond the state minimum standards like the use of designated conservation overlays or other zoning strategies; buyout programs for repetitive loss properties; participation in Community Rating System (CRS) Programs; and strengthening stormwater design requirements for redevelopment/infill. I encourage you to post to SESWA’s online Community Forum at least one resiliency soft solution example from your community for others in our network to look to for ideas to enhance their overall resiliency.

One program we’d like to talk a little more about is the Community Rating System (CRS). CRS is a voluntary program associated with the FEMA National Floodplain Insurance Program (NFIP). While “floodplain” is in the name, there are many stormwater management activities that are credited under this program. Under CRS, communities accrue points for engaging in creditable activities and are rewarded for doing more than regulating construction of new buildings to the minimum national standards. In addition to the benefit of a more resilient community, ALL flood insurance policyholders in the community are rewarded with discounted flood insurance premiums ranging from a 5% to 45% discount. Nationwide, there are 1,505 communities that participate in this program, and more than one-third (531) are in our network, the Southeast! The CRS Data Visualizations page is a great place to visualize the data of participating communities. Additionally, if you want to see where your community ranks within your state, visit your state profiles page.

There are a couple of programs within CRS that can be large contributors to points and resulting reductions in flood insurance premiums. These are “Higher Regulatory Standards” and “Open Space Preservation.” For higher regulatory standards, this page highlights the results by state for freeboard, building codes, higher building construction standards, floodplain use prohibitions, and other higher standards for you to see where your community fits and how you compare with your neighbors. Open space preservation targets land that is located in the Special Flood Hazard Area (SFHA), which is the FEMA regulatory 100-year floodplain. Additional credit is awarded through protecting these areas as open space and not developing within them. This can be accomplished through zoning strategies, enhanced buffer requirements, or land acquisition and conservation. Some coastal areas have begun to explore land use overlay districts as a tool to protect future marsh migration areas to mitigate flooding and improve CRS ratings since these areas are generally the current day floodplain (SFHA).

One item associated with Higher Regulatory Standards is “Freeboard,” which is the additional elevation above the current 100-year floodplain, or base flood elevation (BFE), that buildings are required to be built to for their lowest finished first floor. Freeboard provides a margin of safety against more severe storms and increased future flood risks from the increased frequency of large storms everywhere and rising sea levels along the coast. In most floodplain ordinances, freeboard is generally applied to the SFHA only (e.g., A, AE, or VE flood zones). However, there are a few coastal communities, that have begun to add requirements to the “X 0.2%” flood zone (also referred to as the shaded X zone or 500-year floodplain) because with the addition of sea level rise or occurrence of larger storms, portions of these areas will eventually migrate to the SFHA. This includes Camden County, GA, as well as Hampton, and Norfolk, VA, which have specified to elevate the finished first floor elevation of a building to at least 1 or 1.5 feet above the highest adjacent grade at the building site.

In addition, some communities have developed (and regulate to) a higher “local” or “future” floodplain that is developed by modeling the floodplain considering the impacts of future buildout, re-development, intensity of development, weather-related changes, etc. This also increases the freeboard above the FEMA SFHA.

We hope this article sparked some ideas for soft solutions within your community and we look forward to seeing your posts on SESWA’s online Community Forum.

Did You Miss SESWA's January Webinar?

It’s not too late to view SESWA’s latest webinar titled Intersection of Green and Gray Stormwater Infrastructure: Hybrid Solutions Improve Water Quality and Reduce Flooding. Nuisance flooding in the wrong areas can impose serious threats to vital transportation corridors and human health. Recently completed projects in Raleigh and Beaufort, North Carolina highlight ways that green infrastructure can be used to mitigate flooding and increase the lifespan and effectiveness of existing gray stormwater infrastructure. This free one-hour webinar shared the functional and aesthetic benefits of combining traditional gray stormwater infrastructure with nature-based green stormwater infrastructure to eliminate nuisance flooding while providing water quality benefits and aesthetic improvements. This webinar was brought to SESWA members FREE thanks to the generous support of SESWA’s Communications Sponsors!

WOTUS Update
Kevin Coyne, SESWA

As 2023 ended, a final rule was in place but there was limited guidance on how the rule could be implemented. Many still have questions, as the proposed WOTUS guidance provided some answers but also developed many more questions on applicability of the rule and how states could implement beyond the federal law. As we begin 2024 federal regulators have commented that additional guidance will be developed, but we also anticipate the year to bring new lawsuits, from both the regulated and environmental sectors. In Louisiana, a decision provided some clarity on how states can be limited in overstepping federal guidelines and pending decisions, including one in Kentucky, could provide further evidence on rule implementation. SESWA will continue to monitor WOTUS and any additional guidance and decisions that take place in 2024.

Re-imagine Your Public Meetings with Pop-Ups!
Ariel Bushel, City of Raleigh, NC

Are you looking for a way to increase engagement and attendance at public meetings? The City of Raleigh, NC has recently seen success in “pop-up meetings” which are less formal and bring the information directly to the residents’ communities. Recent pop-up meeting had 5 times the number of attendees than the traditional meeting (located in a community center) for the same project.

Here's how you can plan a pop-up meeting:

  • Select a location within the neighborhood(s). If there are multiple neighborhoods within the project area, you can stagger the pop-ups by week or have them simultaneously.

  • Send letters/postcards to residents, post yard signs in the neighborhood one-two weeks beforehand, and send meeting information via the NextDoor app and by email.

  • Set up one-two tents outdoors with posters related to the project. Pop-up meetings can also be indoors at the neighborhood club house or recreation center.

  • Provide light snacks (chips, popcorn machine, etc.), games (large checkers board, etc.), and music if available.

Benefits:

  • Brings the information to the residents which is convenient and increases attendance.

  • Makes the project more personal and relevant because they are meeting in their neighborhood.

  • Provides an approachable and open environment for residents to share their opinion.

North Carolina 2023 Legislation Summary
Daryl Hammock, W.K. Dickson

The NC legislature introduced a spate of bills in 2023 to alter local stormwater management programs. Most of the proposed changes were aimed at diminishing local regulatory control, weakening protection, or shifting costs to others. After local governments raised concern, many of these bills did not advance or were altered significantly to reduce the effects to stormwater management programs.

The Regulatory Reform Act of 2023 (H600 Section 3) originally sought to fully exempt an owner of a stormwater control measure from paying stormwater fees. In its final form, the bill enabled only a fee credit or fee reduction for stormwater control owners. However, Section 1 of H600 (Session Law 2023-137) resulted in changes that allow land development projects in Water Supply Watersheds to exceed their impervious area cap.

Another bill that ultimately became law that SESWA membership in NC should be aware of is Session Law 2023-134 (Section 12.10(c) of H259) which states that local governments may not deny a draft erosion and sedimentation control plan based solely upon the applicant's need to obtain other environmental permits.

First Stop, Stormwater - Water on Wheels in the Classroom
John Butler, Gwinnett County, GA

Knowing that our children are our future, it makes sense to get water education in front of students as early as possible. In Gwinnett County, GA, a program called “Water on Wheels” has been bringing water education into the classroom for over ten years. This program aligns lessons all about water to the Academic Knowledge Standards (AKS) provided by the school system, making the lessons very attractive to teachers. It turns out that many AKS standards go hand-in-hand with stormwater education. Erosion, habitats, and pollution all show up in various grade level standards. Water on Wheels delivers free education on these stormwater topics by offering in-class field trips for free. Educators develop programs and curriculums and market the opportunity directly to teachers through community partner organizations like Gwinnett Clean & Beautiful and through the Science Curriculum Coordinator at the school system's administrative office. Demand has been steady, even through the pandemic when the program went virtual, up to 15,000 students have been educated each school year, bringing stormwater education to the next generation of leaders at a time when they are most receptive.

Navigating the Uncharted Regulatory Territories for PFAS in 2024

The water sector witnessed a very busy 2023 with various rulemakings proposed, and the year ahead promises to be no different on the regulatory front. As 2024 gets underway, the federal landscape of regulatory activity is poised for some notable and novel actions, especially with respect to PFAS. This ever-evolving regulatory incrementalism – for clean water utilities and stormwater agencies both - warrants keen awareness and participation and oversight from the water sector as proposed Clean Water Act rulemakings are issued and finalized.

On PFAS, the U.S. Environmental Protection Agency (EPA) will be finalizing its efforts to set National Primary Drinking Water Regulations for six individual chemicals in the coming weeks, which will impact every public water supplier in the country. It will also drive future regulatory actions on the clean water and stormwater side simply by the precedent of setting extremely low PFAS limits. Notably, EPA is proposing enforceable levels or Maximum Contaminant Levels for PFOA and PFOS at 4 parts per trillion (ppt) – the lowest analytically detectible level that can be measured with reliability.

EPA is also primed to finalize its efforts to designate PFAS as a hazardous substance under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) – with a purported aim of spurring remediation of contaminated sites and holding polluters responsible for the pollution they caused. However, due to how CERCLA operates in practice, absent Congressional intervention and a protection from liability for passive receivers like clean water agencies and stormwater agencies, the listing of PFAS contaminants under CERCLA will place substantial liability on public agencies and their communities for pollution they had no role in producing, using, or profiting from in the first place. The proposed rule remains under review at the Office of Management and Budget (OMB), but it is expected to be finalized in March. NACWA and many others continue to advocate that PFAS chemical and manufacturing companies must be the ones held responsible for the pollution they create.

Also, ahead on the PFAS regulatory landscape is an analytical methodology for measuring PFAS in the environment. EPA is nearing its completion of its multi-laboratory validation for Method 1633 which can analyze 40 different PFAS chemicals across eight different environmental media (wastewater, sediment, groundwater, etc.). Once EPA finishes this methodology, it is expected to go right into promulgation under the Clean Water Act as a 40 CFR Part 136 Method. The promulgation process is expected to take about a year, so it is likely we will have an enforceable Clean Water Act approved method by mid-2025.

The clean water sector continues to wait for EPA to finalize its aquatic life criteria for PFOA and PFOS which were proposed back in 2021. EPA is reassessing its proposed criteria values due to new peer reviewed science that could drive the proposed values lower. NACWA expects to see these proposed revisions sometime this spring. The Agency is also primed to release draft human health water quality criteria for PFOA and PFOS which use some of the same factors that went into deriving the drinking water standards. These criteria values are expected to be extremely low and will directly impact clean water utilities and likely lead to increased monitoring and BMPs for stormwater utilities, if they are adopted by states into Clean Water Act standards and incorporated into National Pollutant Discharge Elimination System permits.

The next few months are going to be very busy on the PFAS front as the Agency attempts to finalize its regulatory priorities before the November Presidential election. NACWA will continue to advocate at the national level on PFAS issues and welcomes any thoughts from SESWA members on regional or state movement that arises. Please contact Emily Remmel, NACWA’s Senior Director of Regulatory Affairs with questions.
