As the landscaping around our new facilities was designed and installed, our focus was on sustainability. Key elements include:
A) A commitment to significantly reduce our water usage:
1) No grass lawn with the attendant high water usage and expense and ongoing maintenance,
2) Using drip irrigation for over 90% of our developed landscape trees and shrubs,
3) Using native trees and shrubs on undeveloped areas surrounding parking lots that will thrive without irrigation after two years of spot watering,
4) All surface areas mulched to minimize evaporation and weed growth.
B) A commitment to manage the volume and quality of surface water runoff from the roof, sidewalks and parking lots:
1) All surface water runoff is directed into a series of 12 bioswales (rain gardens) that act to clean moderate volumes of runoff water and allow it to be absorbed into the underlying ground water,
2) Infrequent very heavy runoff is directed from the bioswales into a large onsite "dry well" with modest overflow into our 5-acre Johnson Creek Wetland for further cleaning and absorption.
