What is Sustainable Development?

“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Demand for New Urbanism/ Smart Growth Designs

• 12 studies for builders and developers as input to planning new communities– Consumer surveys in Atlanta, Phoenix, Denver, Provo,

Albuquerque, Boise, and Chattanooga conducted in the early part of this decade.

– More recent studies conducted in Tampa, Orlando, Phoenix, Charlotte, and Savannah

– Both urban and suburban locations• Surveys measuring the interest in new urbanism

communities indicate the market for smart growth• Consistently find one third respondents prefer new

urbanism communities and housing product

New Urbanism and Smart Growth Design

• Support Sustainability Agenda• New Urbanism and smart growth designs and

products are similar:– Compact higher density communities– Connect with surrounding neighborhoods– Integrate multiple land uses reducing vehicle trips– Have a definable neighborhood center– Safe streets, and– Protect regional open spaces

Rural Scale Urban Infill Greenfield

Collier County Rural Stewardship PlanCollier County Rural Stewardship Plan• Stewardship Credits are the

“currency”

• Credits are credited from the natural resource and agricultural value of Stewardship Sending Areas multiplied by the layers of development rights removed.

• A Sending Area property owner opts into the program and selects which uses to remove or refrain.

• Credits are calculated using an established GIS database and model.

• Credits are sold to builders of new communities in receiving areas.

Stewardship Sending AreasStewardship Sending Areas• Sending Areas are selected

based on natural resource values, agricultural values or other desirable rural land uses and features.

• Multiple data sets representing a variety of characteristics are integrated through an innovative GIS based scoring system.

• Wetland flow ways, listed species habitats, water resource areas and ranches are typical sending areas.

• Sending Areas are selected based on natural resource values, agricultural values or other desirable rural land uses and features.

• Multiple data sets representing a variety of characteristics are integrated through an innovative GIS based scoring system.

• Wetland flow ways, listed species habitats, water resource areas and ranches are typical sending areas.

Stewardship Receiving AreasStewardship Receiving Areas

• Receiving Area locations are not predetermined, market forces and suitability factors guide the location.

• Desirable characteristics of rural development are integrated into the plan.

• Communities are compact, mixed-use, self-sufficient and pedestrian oriented.

• Design Standards are customized for each new community.

Green Programs NRV• U.S. Green Building Council Leadership in

Energy & Environmental Design (LEED) Certification:

• LEED is a green building rating system that was developed by the US Green Building Council. LEED is a point based system where projects earn LEED points for satisfying specific green building criteria in six categories which include sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation in design.

Green Programs NRV

• LEED for Neighborhood Development: • The LEED for Neighborhood Development Rating

System integrates the principles of smart growth, urbanism and green building into the first national system for neighborhood design. LEED certification provides independent, third-party verification that a development's location and design meet accepted high levels of environmentally responsible, sustainable development.

Green Programs NRV• Clean Marina Program: • This program administered by the Department of

Environmental Protection provides pollution prevention educational information and designation to marinas and boat yard owners. Clean Marinas implement a Clean Marina Action Plan (CMAP) focusing on waste management and pollution prevention.

Green Programs NRV

LID Low Impact Design is an approach to site development that minimizes engineered solutions to water management and minimizes development impact by:

• Decreasing Impervious Surfaces• Reducing Roadway Surfaces• Permeable Pavement Surfaces• Vegetative Roof Systems• Natural Resource Preservation and Xeriscaping

www.lowimpactdevelopment.org/

Green Programs NRV• Energy Star: • Energy Star is a voluntary partnership between the

US EPA and more than 8,000 organizations, including 3,500 of the nation’s home builders. The goal is to increase energy efficiency, decrease utility bills, and help to prevent greenhouse gas emissions. The Energy Star symbol identifies more than 50 types of products such as appliances, lighting, and heating and cooling equipment that are energy efficient.

Green Programs NRV• Florida Water Star:• The program encourages water efficiency in

household appliances, plumbing fixtures, irrigation systems and landscapes. These promote the economic and environmental benefits of efficiency in new home construction.

Green Programs NRV

• Florida Power & Light (FP&L) Build Smart: • FPL’s energy efficient home certification program

offers energy efficient options for homes to certify they are built to a higher standard than Florida code requires.

Green Programs NRV• Green Advantage Certification:• Green Advantage is an environmental

certification for building related practitioners-primarily contractors, subcontractors and trades people. Certified individuals must pass an examination for Commercial, Residential and/or Commercial/Residential Certification that demonstrates their knowledge in green building principles, materials, and techniques.

Green Programs NRV• Florida Yards & Neighborhoods (FY&N): • This voluntary program is a partnership of the

University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS) and provides education and outreach activities in the community to help residents reduce pollution, conserve water, and enhance their environment by improving home and landscape management.

Green Programs NRV• Firewise Communities & Wildfire Hazard

Assessment Guide for Florida Homeowners: • The program recognizes those communities that

determine if a wildfire hazard exists in a community, evaluate the risk, and implement Firewise principles to mitigate the risk.
