Adrienne Nemura Contributed to the 2020 National Municipal Separate Storm Sewer System (MS4) Needs Assessment Survey Results Published by the Water Environment Federation Stormwater Institute
Adrienne Nemura, P.E. (Ohio) was invited to be part of the National MS4 Needs Assessment Survey Work Team which authored the 2nd Biennial Report entitled "2020 National Municipal Separate Storm Sewer System (MS4) Needs Assessment Survey Results" that was published by the Water Environment Federation Stormwater Institute (SWI).
The report identifies the challenges, needs, and drivers for MS4 programs in the U.S.. There are 855 Phase I MS4s (medium or large urbanized areas with populations > 100,000) and 6,695 Phase II MS4s (smaller urbanized areas with populations > 50,000, federally owned systems such as military bases, departments of transportation, universities, schools). These numbers may increase with the 2020 Census.
Adrienne Nemura is a Principal Water Resources Engineer based in Ohio with more than 36 years of experience focused on helping clients identify cost-effective and sustainable solutions to meet their water quality goals. She has worked for more than 40 cities and wastewater utilities, state and federal regulatory agencies, industrial facilities, airports, attorneys, consulting firms, non-profit organizations, and trade associations.
The Stormwater Institute currently has three active work teams: the National Municipal Separate Storm Sewer System (MS4) Needs Assessment Survey, the National Municipal Stormwater and Green Infrastructure Awards Program, and Policy. SWI work teams include interested SWI Advisory Committee members, employees of SWI Subscriber organizations, WEF technical committee members, and when applicable, invited subject-matter experts.
The Water Environment Federation Stormwater Institute is a center for excellence and innovation focused on best-in-class solutions to urban runoff and wet weather issues.
The WEF Stormwater Institute has completed two iterations of the National Municipal Separate Storm Sewer System (MS4) Needs Assessment Survey – the first in 2018 and the second in 2020. The primary objectives of these surveys are
- to better understand MS4 program challenges,
- to identify the information and resource needs of MS4 permittees, and
- to approximate current funding levels and estimated funding needs in the MS4 sector.
In the 2020 survey, WEF received 804 responses from 47 states, the District of Columbia, and Puerto Rico.
The WEF Stormwater Institute gratefully acknowledges the MS4 Survey Work Team for their contribution to the development and deployment of the survey, as well as the analysis of the results. This version also includes a Data Dashboard that enables users to filter data in various ways.
