The community should expect most funding for future capital improvements to come from local public sources. Substantial investments in transportation facilities-- including parking, sewage collection and conveyance, and stormwater facilities will be needed over the 20 year planning period. Funding for open space acquisition and parks improvements may also be needed to meet community expectations. Private development will finance some minor new capital improvements, such as stormwater facilities, sewage conveyance improvements, and transportation improvements where proposed development will exceed adopted levels of service. Impact fees on new development will also generate some revenue to offset the impact of such growth on Mercer Island’s public schools, parks and open space, and transportation facilities.
