4. New Jersey Future’s
Mainstreaming Green Infrastructure program
 Working directly with towns to provide education, training
and technical assistance to improve water quality, reduce
flooding and sustain vibrant, healthy communities.
 Facilitating and accelerating demonstration projects that
show innovative, impressive, effective use of green
infrastructure
 Working with state agencies to update and improve rules,
manuals, standards, programs, and review processes to
facilitate GI
 Convening a Developers’ Green Infrastructure Task Force
to help developers and design professionals to learn about,
finance, and build high-quality, cost-effective GI.

5. Developers’ Green Infrastructure Task Force
The Task Force helps New Jersey’s developers
and their design professionals learn about finance, and build
high-quality, cost-effective green stormwater infrastructure.

6. What is green infrastructure?
•
•
An approach to
managing stormwater
by either enabling it to
infiltrate into the ground
where it falls or by
capturing it for later
reuse.
GI Practices:
• Bioretention (rain
gardens)
• Stormwater tree
trenches
• Permeable Pavement
• Green roofs
• Cisterns & Rain barrels

90. Getting started with Green Infrastructure
I want green infrastructure for my project…
 Can be used to meet regulatory requirements
 Variety and flexibility of GI techniques
 Offers aesthetic amenity
… but how do I get started?
 Which techniques are most effective for my project?
 How much GI do I need?
 What are the construction and maintenance costs?

91. A quick note…
Green Infrastructure (GI)
=
Low Impact Development (LID)
=
Best Management Practice (BMP)
=
Stormwater Management Practice (SMP)
=
Stormwater Features

92. Green Infrastructure Design Tools
• Many online tools developed to assess GI
• Compile relevant information (soil type, land cover, etc.)
• Inform conceptual-level designs
• Generate “what if” scenarios
• Four web-based tools for today’s discussion
1. EPA National Stormwater Calculator
2. NYC Green Infrastructure Co-Benefits Calculator
3. National Green Values Calculator
4. Autocase

93. Use and Limitations
• Using these tools
• Planning- and conceptual- level design
• Inform design process
• Gather estimates of sizing, construction costs, and
maintenance costs
• Help communicate concepts to clients, planning
commission, community organizations
• Limitations
• Lack of correlation with local and state regulations
• These tools alone will not get you a permit
• Do not provide technical support required for site-level
design
• These tools cannot be your engineer

94. 1. EPA National Stormwater Calculator
• Intended users - both technical and non-technical
• Site developers
• Landscape architects
• Urban planners
• Homeowners
• Tool focus
• Screening level analysis of small sites (under 12 acres)
• Informing user how well they can meet a stormwater
retention target (example: manage first 1.5” of rainfall
event)

95. 1. EPA National Stormwater Calculator
Benefits
• Free
• Easy to run, store, and
compare scenarios
• Summary of
construction and
maintenance costs
Drawbacks
• Intended for small
sites (<12 acres)
• Not correlated with
local regulatory
requirements

106. 3. NYC GI Co-Benefits Calculator
• Developed by NYC DEP
• Intended users
• Planners
• Developers
• Academics
• Tool focus
• Quantify co-benefits of GI (increased property value,
improved quality of life, carbon sequestration, etc.)
• Compare GI Options

107. 3. NYC GI Co-Benefits Calculator
Benefits
• Free
• Useful for community
outreach to highlight
additional benefits
• Social, environmental
benefits
Drawbacks
• Developed specifically
for NYC
• Lacks basic site feature
inputs (soil type,
infiltration rate)
• Not correlated with
regional regulatory
requirements

110. 4. Autocase
• Software developed by Impact Infrastructure
• Intended users
• Developers
• Engineers
• Municipalities
• Tool focus
• Optimization of lifecycle costs of a project
• Triple bottom line framework: economic, social,
environmental costs
Note: not affiliated with Autodesk

111. 4. Autocase
Benefits
• Pulls site-specific
information from
national databases
• Aesthetic results panel
for communication of
results for planning
commission or
community
Drawbacks
• License model, most
users pay between
$1,500 and $25,000
• Social and
environmental costs
less tangible than
financial costs
• Not correlated with
regulatory
requirements

114. Use and Limitations
• Using these tools
• Planning- and conceptual- level design
• Inform design process
• Gather sizing, cost, and maintenance estimates
• Help communicate concepts to clients
• Limitations
• Lack of correlation with local and state regulations
• Methodologies, goals
• Do not provide technical support for site-level design
