<br />Option No. 1: Street Drainage <br /> - In the River Road and Santa Clara neighborhoods, “greenfrastructure” <br />surface water management solutions can “backstop” some of the rural streetscape preservation ideas <br />discussed elsewhere in this White Paper. One option is retention of open drainage ditches - re-constituted <br />as bio-swales - that provide for many water quality and quantity benefits that are lost or that have to be <br />engineered in conventional piped solutions to storm run-off. Adoption of such standards would <br />compliment any changes in street section standards that preserve rural street appearance. <br /> <br />Option No. 2: Integration with Open Space Preservation <br /> - Another iteration of greenfrastructure <br />solutions approaches is to incorporate water quality/quantity treatment or retention ponds directly into <br />open space and park facilities, helping to control water flows and quality while also providing an open <br />space and visual amenity. The preservation and restoration of streams and other natural water features, <br />riparian zones, wetlands, 100-year floodplain, and natural drainage systems also can make significant <br />contributions to water quality and flood management without resorting to “engineered” solutions. <br /> <br />40 <br />River Road/Santa Clara Transition/Heritage White Paper <br />DRAFT <br />11-24-05 <br /> <br />Service provider Review <br /> <br />
