Drainage Rate Increase FAQ
How much will drainage bills change in 2009?
Effective January 1, 2009, the change in residential drainage bills for parcels less than 10,000 square feet will range from an increase of $0.96 per month, or $11.52 per year, for parcels less than 3,000 square feet to an increase of $3.62 per month, or $43.38 per year, for parcels 7,000 to 9,999 square feet.
Commercial and large residential bill increases will vary depending on the rate category to which a parcel is assigned, which is based on a parcel’s percent of impervious surface area and whether it qualifies for a low impact rate.
Why is this rate increase necessary?
The drainage rate increase was driven by the need to maintain and improve the pipes and natural systems that convey stormwater. These natural and built systems reduce the risk to life and property related to stormwater, mitigate the impact of stormwater runoff to lakes, creeks, wetlands and shorelines, and insure compliance with regulatory and legal requirements. The 2009 rate increase will help fund new capital and operating programs recommended in the Comprehensive Drainage Plan. Capital improvements include a long-term solution for Madison Valley, a study of South Park storm drainage and water quality, combined sewer overflow projects at Windermere and South Henderson, and utility relocation work necessitated by the Alaskan Way Viaduct and Seawall Replacement Project. Operating programs include NPDES permit compliance requirements, additional field resources needs, and technology costs associated with combined sewer overflow monitoring and stormwater management.
