In this example, the minimum required open space is directlyproportional to the lot size, thereby maintaining comparable densities while providing a densitybonus for increased open space. The open space may fulfill parkland needs, provide for bufferingof adjacent uses, and/or protect site resources such as woodlands or areas of the floodplain. Eachdevelopment type would be permitted by-right subject to other performance standards to ensurecompatibility.Comprehensive PlanActions and Initiativesa. Continue efforts to meet the provisions of the U.S. Conference of MayorsClimate Protection Agreement (see Insert Three), including:• Conduct an inventory of greenhouse gas emissions as a means toestablish a baseline standard, as the premise of the agreement is based onimprovement.• Establish an action plan forgreenhouse gas reductions. Thisplan should identify the mostpromising strategies for greenhousegas reductions, such as reducingthe emissions from buildings andvehicles.• Implement the action plan to achievethe climate protection agreementgoals.b. Seek alternative transportation solutionsat the local and regional levels topreserve air quality. Nonpoint sourcetransportation impacts represent up to 40percent of the pollution levels. Measuresthat may help reduce vehicle emissionsinclude, but are not limited to:• Increased opportunities for bicyclingand walking by way of completestreets and other pedestrianimprovements.• Coordinating with SIU for theINSERT FOUR: MUNICIPAL GREEN BUILD-ING (LEED) POLICYMany companies and municipalities arecommitting to building green facilities as a matterof policy. Although the definition of a greenbuilding can vary, the most widely acceptedbenchmarks are established by the US GreenBuilding Council (www.usgbc.org). These greendesign standards are collectively known as theLeadership in Energy and Environmental Design(LEED) system, which evaluates green buildingsaccording to specific criteria. There are five generalareas:1. Sustainable site planning2. Safeguarding water and water efficiency3. Energy efficiency and renewable energy4. Conservation of materials and resources5.
