As planners, we are tasked with the responsibility to provide a sustainable community:
Some of which can include:
⢠Conservation of Natural Resources
⢠Preservation of Native Habitats
⢠Protection of Agricultural Lands
⢠Storm Water Plan
⢠Water Supply Plan
⢠Water Reuse/Wastewater Reduction
⢠Pollution Control
But how can landscaping help make our communities sustainable?
⢠Encourage the use of Green Infrastructure
⢠Repurpose Storm Water Runoff
⢠Protect Waterfronts and Waterways with Transitional Habitats

Water that runs off a lawn and
pavement carries pesticides, fertilizers,
and harmful substances that contribute
to nonpoint source pollution.
These waters can also collect
chemicals from roadways such as oil,
A/C refrigerant, paint and soap.
Repurpose Storm Water Runoff

Storm Water
![Page 12: WalkingDead - American Planning Association...WalkingDead Communities How You Can Help Blighted Areas Eric M. Power, AICP LIAF Laura A. Warner, ED.D September 10, 2015 Sunrise in Action!](https://reader033.vdocuments.us/reader033/viewer/2022042402/5f1293b112f07b65ea447409/html5/thumbnails/12.jpg)
Green infrastructure is an approach that communities can choose to use that can
maintain healthier water systems which can provide multiple environmental
benefits and further support sustainable communities.
Definition provided by EPAEpa.gov/water
Unlike traditional storm water (or grey) infrastructure, which uses pipes to
dispose of rainwater, green infrastructure uses vegetation and soil to
manage rainwater where it falls.
What is Green Infrastructure?
![Page 13: WalkingDead - American Planning Association...WalkingDead Communities How You Can Help Blighted Areas Eric M. Power, AICP LIAF Laura A.

Trees are known to help with:
Stormwater Reduction
Aesthetically pleasing and safer neighborhoods
Energy Conservation
Property Values
Air Quality/ CO2 sequestration

The use of plants and algae to reduce contaminant materials through a plants
natural processes.
Used by the EPA since the 1990âs at superfund sites.
It is important to use native plants in this process as non-native plants may
become invasive when given an abundance of nutrients such as phosphorus and
nitrogen.
The introduction of vegetation into a stagnant storm pond, not only can help
reduce toxins, but can introduce wildlife and provide habitat.
Phytoremediation
Trees can remove dangerous elements such as cadmium, chormium, nickel and
lead from polluted water.

Aquatic Plants
⢠Reduce infestations of invasive water plants and algae
⢠Provide food sources and habitat for vulnerable animals such as amphibians and
fish fry
⢠Improve overall appearance and value of the area
⢠Helps to filter and remove dangerous chemicals such as phosphorus and nitrogen
commonly found in fertilizers

⢠Allows for roots to grow underneath
infrastructure
⢠Allows for storm water to irrigate
instead of sprinklers
⢠Allows more room for sidewalks &
benches
Green Streets
⢠Allows for trees to thrive in urban
environments.
⢠Allows for plants or surfaces like
permeable pavers to receive water
before it goes to a drain

The plastic frames (silva cells) keep the soil from being compacted. The gaps in the
frames permit roots to roam in search of good soil and moisture and also increases
the area for stormwater retention.

⢠Green Roofs
⢠Permeable Pavement
⢠Bioswales
⢠Cisterns (Rain Water Harvesting)
⢠Have runoff first lead to vegetation, than to a
sewer system

What can be done?
⢠Incorporate Green Infrastructure principles into your City Code and
Engineering Design Guidelines
⢠Plant more trees!
⢠Advertise any time GI is used
⢠Educate Decision Makers
⢠Educate those who donât know
⢠Relax normal code requirements for pocket parks (passive ones too)
⢠Allow for Alternative Design Standards

Established in 1983, The Landscape Inspectors Association of Florida provides
education and certification to Landscape Professionals through annual seminars,
monthly meetings and our website.
What is LIAF?
LIAF members are:
Landscape Inspectors (Municipal and Private)
Nursery Owners
Installers
Property Managers
Code Officers
Landscape Architects
Master Gardeners
And yesâŚ.even Planners
Our certification program trains inspectors to evaluate landscape material using the
Florida Grades and Standards for Nursery Plants, a State of Florida document
introduced in 1965. The manual uses a rating system to provide quality trees, palms
and shrubs to consumers.
