GREEN STREETS | GREEN JOBS | GREEN TOWNS INITIATIVE
Hie Green Streets, Green Jobs, Green Towns Partnership (G3) aims to stimulate the green jobs market and enable families to work
where they live and play. Small to mid-sized communities can boost their local economies and protect water resources through the
use of watershed planning, design and construction of stormwater best management practices.

The project incorporates the
replacement of failing utilities
beneath the roadway, replacement
of failing pavement and
incorporation of safety elements by
including sidewalks (compliant
with the Americans with
Disabilities Act). The project
integrates stormwater features such
as bioswales and bioretention areas
that incorporate local foliage to
provide a sustainable nutrient and
pollutant removal system.
The grant providing by the G3
program supported the design
costs, and the construction costs
Green Streets, Green Jobs, Green Towns Initiative // Stories of Green Infrastructure
The Walnut Street project, in the
small town of Delmar, shared
across the Maryland-Delaware line,
serves as an ideal demonstration of
green infrastructure: The Town
needed to tackle major roadway
reconstruction and infrastructure
work and because the demolition
needed to occur, the Town decided
to "put the street back together" in
a green way at little additional
construction cost but big savings on
stormwater management down the
road.
were provided by the town itself as
part of the infrastructure program.
The design was completed in 2012,
street construction began on
November 5, 2012, and was
completed in May 2014.

PROJECT ELEMENTS
•	Impervious pavement removal- Removal of pavement - about 8 feet of
roadway to narrow it - allows installation of other practices that treat stonnwater.
•	Bioretention curb extensions and bioswales- These features filter and reduce
stonnwater runoff, allowing it to infiltrate into the ground before it enters into the
storm drain system.
•	Tree pits and expanded tree wells- Extended tree pits and wells into the street
both reduces impervious surface cover and also reduces street area, narrowing the
road and slowing traffic, increasing likelihood of pedestrian use.
•	Gravel filters - Filterra systems and gravel filters slow water and collect
pollutants on media that is replaced periodically.
•	Increased Urban Tree Canopy- In urban areas a single tree can intercept from
500 to 4,000 gallons per year. Even young, small trees help, capturing 50 gallons
per year. Trees not only treat stonnwater, they provide a host of other benefits,
including energy cost reduction in both summer (shade) and winter (proper
placement can result in the reduction of energy use by 20-50%), aesthetics,
property value enhancement, business traffic enhancement, and health benefits.
SUSTAINABILITY & GROWTH: ADDITIONAL GREEN ACTIVITIES
Delmar, "the little Town too big for one state," is actually two incorporated towns:
Delmar, Delaware, governed by a Mayor and four council members is located in
Sussex County. Delmar, Maryland, governed by a Mayor and four commissioners,
is located in Wicomico County. The Towns share a central administration police
department, public works department, and sewer/water facilities that are jointly
owned and operated.
Together, both sides of this Town worked on the green street, which will be the
kickoff to the next generation of green activities in the town. Previously, the two
sides of Delmar worked together to upgrade the wastewater treatment facility to
include the addition of biological and enhanced nutrient removal systems that
effectively reduce pollutants-nitrogen and phosphorus loadings from entering the
waterways that drain into the Chesapeake Bay.
In other areas of the community, both the elementary and middle/high schools have
long been pursuing outdoor environmental activities for their students, sending
hundreds of students on field trips to learn about watershed issues and bring lessons
back to the schools.
