Background

❏Five year development

❏Major investment from WB and US EPA

❏Collaboration with local partners

Management Needs

❏ Green infrastructure (GI) is

a multi-benefit solution to

address stormwater

concerns

❏ Municipalities are required

to develop and implement

watershed GI plans

❏…but key questions remain

Where are possible

locations?

Where are effective

locations?

How much runoff and loads are reduced?

What are the most cost-effective GI

combinations?

Where has GI been

implemented?

GreenPlan-IT Overview

❏ Quantitative, robust,

and flexible

❏ Scientifically

rigorous

❏ Open source

GIS Site Locator Tool ID potential locations for GI

▪ Utilize regional and local GIS layers

▪ Rank locations based on local priorities and GI properties

Modeling Tool (SWMM)

Quantify water quality and quantity benefits from GI implementation

▪ Establish baseline condition

▪ ID critical runoff and pollutant source areas

▪ Estimate GI benefits

▪ Set stage for cost-benefit analysis

Optimization Tool

Determine the most cost-effective GI solutions

▪ Multi-objective optimization

▪ Input of GI cost/design

▪ Modeling tool as simulation engine

Tracker

Web-based REGIONAL GI database

▪ Record attributes of each site, streamlining annual reporting

▪ Display planned, potential, and implemented projects

▪ Estimate and report GI effectiveness

Regional Application for Supporting GI Planning

● ABAG East Bay Corridors

● San Mateo

● San Jose

● Sunnyvale

● Oakland

● Richmond

● Richmond/Contra Costa County

Support Wetland Restoration Planning

Healthy Watersheds Resilient Baylands

❑ Prioritize and identify

wetland restoration

projects

❑ Reduce stormwater

runoff and nutrient

loads to Laguna de

Santa Rosa

Ongoing Applications

Healthy Watersheds

Resilient Baylands

❏ Integrate water quality

benefits and ecological

functions

❏ Identify areas where GI

and urban forestry can

act synergistically to

achieve multiple benefits

Ongoing Applications

Preparing for the Storm ❏ Valley-wide Urban

Greening Vision

❏ Focus on flood control

and groundwater

infiltrationlands
