• Lighting — Use low wattage lighting and "dark sky" tech- <br /> nologies. <br /> • Finishes — Use materials with natural and no/low vola- <br /> tile organic compounds (VOC). <br /> • Minimize Heat Island Effect — Provide shade trees and <br /> high solar reflectance materials. <br /> • Minimize Runoff — Minimize paved areas and consider <br /> permeable pavements. <br /> • Effective Stormwater Treatment — Use rain gardens, <br /> efficient stormwater conveyance, maximize plantings <br /> for evapotranspiration and design stormwater facilities <br /> as a site amenity. <br /> • Minimize Pollutant Sources —Control selection of mate- <br /> rial and finishes, minimize use of chemical for mainte- <br /> nance and use catch basin oil/water separators. <br /> Building sustainability opportunities include: <br /> • General — Use natural light and ventilation and local/ <br /> recycled/reused materials. <br /> • Concrete — Specify high fly ash content (to increase <br /> recycled material use), water based stains, and reduce <br /> materials usage where possible. <br /> • Rough Carpentry — Use Forest Stewardship Council <br /> (FSC) lumber and engineered lumber in lieu of milled <br /> timbers, and re-use existing lumber when available. <br /> Life Cycle Cost Analysis <br /> A Life Cycle Cost Analysis was performed concurrent with the <br /> master plan design to assist the city in meeting its goal of cre- <br /> ating a cost-effective park design using the most sustainable <br /> materials. Ten park systems were selected by the city and al- <br /> ternatives were evaluated for comparative performance and <br /> cost during a 50-year park life span, including initial costs, op- <br /> eration and maintenance costs, and disposal and/or replace- <br /> ment costs. The analysis results for these ten park systems <br /> were utilized in informing decisions about park systems and <br /> materials. The Life Cycle Cost Analysis is in the Appendices. <br /> Accessibility <br /> It is the city's goal to make all park activities accessible to all <br /> park users in conformance with the Americans with Disabilities <br /> Act (ADA). ADA Accessibility Guidelines (ADAAG) were incor- <br /> porated into the park design including the pathway system, <br /> choice of surfacing, and design of buildings. Site furnishings <br /> will be in compliance with ADAAG and applicable safety stan- <br /> dards. <br /> Senator Henry M Jackson Park Master Plan 7 <br />
