Right-of-Way Improvements for Stormwater Management
The City of Beaverton strives for efficiency when scheduling projects, and coordinates utility repairs to minimize the impact on a neighborhood and reduce project cost. During a recent project located at the junction of SW Schiller Road and SW Valley View Drive, the city identified an opportunity to demonstrate low impact development to improve stormwater management. Along with the street resurfacing, the city took the opportunity to improve stormwater management by reshaping the drainage ditch and replanting.
The project goals included removal of invasive plants, planting of native trees and water quality plants, reduction of pollutants from road run-off, and slowing down the stormwater flow to protect against erosion. The attractive landscaping also improves the stormwater drainage function.
Sustainable stormwater management mimics nature by integrating stormwater runoff into the surrounding terrain to store and treat runoff. Pollutants are removed naturally by vegetation and soil, and the stormwater can then replenish groundwater. Natural hydrological cycles and groundwater replenishment are not disturbed, and pollutant treatment is usually more effective. Construction and maintenance costs are comparable and often can be less.
The city is committed to bringing native species to Beaverton. Native plants and trees need less water and chemicals than non-native species, are more resistant to pests and diseases, and also attract birds, butterflies and other beneficial wildlife. Simultaneously, they also reduce erosion and protect water quality. List of native plants.
On November 1, 2014 at Cedar Park off of Cedar Hills Boulevard, 47 trees were planted with the help of Friends of Trees and 30 volunteers. The trees matched what was already planted in the area including: red maples, Western red cedars and shore pines.
