PLANNING VISION MODELS A GREEN CITY
Greenprint Raleigh’s guiding vision and principles promote
environmental sustainability and stewardship; through enhanced
policy framework and land management practices, the
City protects sensitive lands while preserving water,
air and land resources. The Unified Development
Ordinance addresses contemporary development
and zoning practices while acknowledging
market trends, incorporating best practices and
focusing on contextual issues throughout the city.
WATER EFFICIENCY IS KEY
City programs educate customers about the most
water-efficient technologies, including the toilet rebate
program, and help them understand the City’s mandatory
conservation measures, providing resources and tools.
GREEN INFRASTRUCTURE IMPROVES WATER QUALITY
Projects to improve surface water quality in Raleigh’s streams
include stream restoration and enhancement; constructing
wetlands and rain gardens; and installing cisterns, green roofs, or
other retrofits to reduce stormwater pollution.
UPPER NEUSE CLEAN WATER INITIATIVE PROTECTS WATER SUPPLY
The Upper Neuse Clean Water Initiative, a comprehensive
conservation plan, identifies and ranks land most critical for
water supply protection in the Upper Neuse River Basin. The
City provides marginal financial assistance as needed to
complement other funding sources for priority purchases.
URBAN FORESTRY PRIORITIZES HEALTH AND ENVIRONMENT
A
Tree City USA
for 24 years, the City’s skilled arborists ensure
Raleigh remains the
City of Oaks
by managing existing trees and
planting the next generation. The urban forest increases property
values, improves air and water quality, reduces heating and
cooling costs and increases public health and wellness.
One acre of forest absorbs six tons of CO2 and emits four tons
of oxygen annually, enough to meet the needs of 18 people.
SUSTAINABLE GREENHOUSE
GROWS SAVINGS
The City used grant funds
to upfit its new Marsh
Creek Greenhouse with
several sustainable prac-
tices and technologies;
building this efficient green-
house structure decreased resources
needed to provide a desirable growing
environment.
Water Reclamation
Two large cisterns
collect 4,800 gallons of rainwater, stored
to water plants.
Automation and Controls
An advanced
computer system fully automates shade
systems, heating, cooling and irrigation.
The shade system will automatically open
and close depending on the temperatures
to help reduce energy costs and provide
the opportunity to grow year round.
Polycarbonate Skin
Polycarbonate dou-
ble layer skin provides 50% better insulation
than glass panels, reducing heating and
cooling costs and use of fossil fuel.
Evaporative Cooling
A system installed
along the west side of the greenhouse
uses cooling pads moistened by recircu-
lated water. Exhaust fans on the east then
efficiently pull the cool air through the
greenhouse.
