Planning to Action Climate Tool

This tool guides communities through the process of turning climate planning into sustainable financing of on-the-ground projects

SNEP Network Partner, Throwe Environmental, has adapted and tested the US Climate Toolkit to a tool that supports its broad range of SNEP Network technical assistance projects. This new tool helps communities prioritize climate resilience actions while engaging community stakeholders and staff to build local capacity.

Nature Based Solutions Spatial Mapping Tool (Massachusetts)

 This tool helps communities identify where nature-based solutions (NBS) can most effectively address natural hazards and contribute to resilience planning at a local level.

This tool uses existing statewide datasets and analyses to create easily understandable layers that highlight a range of potential actions and next steps. The results are intended as a high-level screening tool to identify places where conservation and restoration can help combat drought susceptibility, inland and coastal flooding hazards, and contribute to ecosystem co-benefits.


Stormwater Planning Series

Participants use the tools and techniques in the Stormwater Retrofit Manual and presented in the training to identify low-cost stormwater solutions to address the stormwater problem at their specific location.

In response to municipalities’ requests for stormwater planning assistance, the SNEP Network developed the “Stormwater Training/Facilitated Planning Series” which collectively guides communities to develop to a conceptual design for a nature-based stormwater retrofit option in their selected drainage area. The planning series is held virtually with five training sessions over the course of six months. At the outset of the series, a site visit to the selected area is scheduled for the SNEP Network team and community members to see first-hand and discuss the area’s challenges and opportunities with respect to managing stormwater.

Buffer Restoration Guide

This guide is intended to assist public and private property owners in RI and southeast MA who are interested in restoring and improving buffers along a river, pond, lake or the coast. 

While this guide is not an exhaustive resource, it is intended to give buffer property owners enough information and resources to design and implement their own restoration project. This resource takes you through the process of identifying site factors and establishing the goals for the site, to considering buffer options, installation, and maintenance. View the Factsheet HERE.

Bylaw Review Tool (Massachusetts)

The Bylaw Review Tool allows you to compare local land use regulations with best practices.

The analysis framework in the Bylaw Review Tool is designed to assist communities in applying cost-effective low impact development (LID) techniques. This template allows you to evaluate local land use regulations in relation to models. Key areas of analysis in the Bylaw Tool include:

Overall Site Design: Open Space Residential Design (OSRD) vs. conventional subdivisions
Project design and layout standards in relation to LID: Road layout width, curbing, drainage, sidewalks, parking, landscaping
Maintenance and operations, mechanisms for enforcement: Who is responsible for maintaining drainage/LID; easements, homeowner association option, municipal inspection and administration systems

Check out the Bylaw Review Tool storymap with step-by-step instructions on how to use the Bylaw Review Tool. View the Factsheet HERE.

LID Checklist (Rhode Island)

The self-assessment allows an in-depth review of the standards, ordinances, and regulations that shape development in your community, which directly influences the health and quality of land and water resources.

The assessment attempts to guide you through a systematic comparison of your local development rules against current model development principles. The questions identify specific methods to reduce runoff from new construction and redevelopment and include topics ranging from open space and land disturbance to impervious surfaces and soil erosion control.

Hydrologic Response Units (HRU) Mapping

SNEP Network Partner, Cape Cod Commission, developed a methodology that used state-wide publicly available GIS layers for land use, land cover, and soil type to determine Hydrologic Response Units (HRUs).

Having a transparent method for determining Hydrologic Response Units will improve consistency of stormwater analyses, making regional comparisons and updates to analyses easier and more straightforward.Because Hydrologic Response Units are derived from data available for the entire State of Massachusetts, this process can be easily replicated anywhere within the state, and with minor modifications can be adapted to use other data sets (from other states or more specialized, local data).Methods used to estimate or model runoff and plan interventions can vary widely, and often utilize opaque or proprietary approaches which may be challenging to update. 

While the technical challenges of the interactive viewer are being developed, staff can provide the HRU data files for exploration in ArcGIS, and may be able to provide other means to view and interact with HRU data for smaller geographic areas. For more information, please contact Tim Pasakarnis at 


Stormwater Retrofit Manual

The manual takes practitioners through the fundamental approach for retrofit, sizing, design and performance characterization, an introduction of performance curves and stormwater control measure design criteria including detailed sizing requirements and guidance.

The manual offers an alternative approach that is practical, achievable, and can offer solutions to communities’ size restrictions, while achieving measured and verified infiltration and pollution goals. This manual does NOT intend to replace existing federal, state or local requirements for stormwater management. Instead it should be used as supplemental guidance and a resource to support smart choices in site design as it relates to the mitigation of stormwater impacts from existing developed areas.

Tree Trench Options Guide

This Guide is a tool to assist with the design process given specific stormwater objectives, site context, aesthetics, tree health, and maintenance capabilities. It is intended to encourage a creative, multi-functional design approach specific to each project’s needs, goals, and budget. 

The guide will help improve communication between designers and municipalities as they plan and implement their green infrastructure projects. It was developed to give municipalities a manual to help design and maintain resilient tree trenches. It was developed in companion to other existing manuals and can be used to assist with the design process.

EPA’s BMP Accounting and Tracking Tool (BATT)

BATT is a spreadsheet-based tool that provides accounting, tracking, and reporting for pollutant (nutrients and sediment) load reduction. The tool allows for aggregate, summary reporting (e.g., overall phosphorus reductions) for compliance with MS4 permit requirements for communities by major watershed.

The University of New Hampshire (UNH)- Stormwater Center, a SNEP Network Parnter, along with EPA Region 1, Paradigm, and the Consensus Building Institute worked together to develop training tutorials that helps support municipalities in using EPA’s BMP Accounting and Tracking Tool (BATT). 

Emerging Stormwater Technologies in Rhode Island

Jellyfish Filters

This webinar will provide an overview on the process of selecting and designing a proprietary stormwater treatment device for permitting in Rhode Island, with a focus on the Jellyfish Filter. Although this training is specific to RI, the information that will be presented is extremely valuable and relevant for all designers, reviewers, and municipalities interested in learning about implementing proprietary stormwater treatment devices to meet water quality goals and/or TMDL requirements on challenging sites.


FocalPoint is an on-line stormwater BMP that utilizes regionally acceptable vegetation planted in a high-flow rate biofiltration media layer that treats stormwater pollutants such as total suspended solids (TSS), nutrients, metals and bacteria.  The high-flow rate media allows for a system footprint that is notably smaller than that of traditionally sized filtering BMPs, making it an ideal option for sites with limited amounts of available space.  The system also has an optional modular underdrain which can be used to provide additional subsurface storage/detention.


Funding and Financing Inventory

The SNEP Network created a clearinghouse of federal, state, and philanthropic grant opportunities relative to stormwater/watershed management, ecological restoration and climate resilience. The grant funding list includes detailed information about the funding source, match requirements, type of funding, eligibility, time frame, funds available and how to apply. 

Financing 101

What is stormwater financing? Check out this webinar to learn about how stormwater programs are managed, the basics of setting stormwater utility fees, and examples of stormwater program implementation. This webinar will also cover the legislation in Southern New England that enables communities to establish stormwater utility programs

Stormwater Innovation Center

The goal of the Stormwater Innovation Center is to demonstrate to communities throughout Rhode Island and Southeast New England strategies for improving urban water quality and associated wildlife habitat through the use of innovative green stormwater practices.

A wide range of green infrastructure has already been implemented in Roger Williams Park, to reduce stormwater contaminants from entering the ponds and degrading water quality. The Stormwater Innovation Center will use these structures and practices to provide hands-on training for municipalities, engineers, construction companies and scientists who will learn from the successes and failures of their design, implementation, and maintenance.

The Innovation Center has been developed by a partnership between the City of Providence Parks DepartmentAudubon Society of Rhode IslandThe Nature Conservancythe University of Rhode Island’s Coastal Institute,  Restore America’s EstuariesRhode Island Department of Transportation, the SNEP NetworkThe Robbins-de Beaumont Foundation  and the University of New Hampshire Stormwater Center.


On Demand Webinars on Green Infrastructure Maintenance

Green Stormwater Project Construction Oversight

Stormwater project designs are only effective when they are constructed correctly. This workshop describes the key phases for construction of stormwater practices, highlighting strategies that project managers can use to ensure proper installation. The training will include descriptions of lessons learned, illustrated with examples from the field. The training is for service providers involved with the construction and installation of green stormwater infrastructure

Maintaining Green Stormwater Infrastructure

This training is intended for supervisors and field staff responsible for maintaining green stormwater infrastructure projects.  Without appropriate operation and maintenance activities GSI projects will not continue to function properly and yield expected water quality and environmental benefits, meet legal standards, and protect the communities’ financial investment.  In this training with the Providence Stormwater Innovation Center, we will give an overview of GSI function and maintenance issues, how design and construction decisions affect future maintenance, lessons learned from the field and the importance of routine inspections and tracking changes over time.

City of Pawtucket, RI Stormwater Maintenance Videos

As part of the Pine Street Green Street project, located in Pawtucket’s Transportation Oriented District and installed with funding from SNEP Watershed Implementation Grants (SWIG), a series of maintenance videos have been developed and posted on the City of Pawtucket’s website. The training videos teach staff about maintenance requirements for green infrastructure, and is applicable to anyone who would like to learn more about maintenance of green infrastructure.
