In a stormwater system that collects, moves, and treats stormwater—or rain and snowmelt—before releasing it into local waterways. Stormwater runoff from streets, roofs, parking lots and landscape runs downhill in ditches and pipes to multiple creeks that lead to Fanno Creek and the Tualatin River.
The portion of the rate increasing in January covers the part of the system maintained by the city of Tigard:
- Miles of pipe - 135
- Catch Basins - 4,801
- Water Quality Facilities - 240
Key Performance Indicators
- Miles of pipe inspected annually - 21
- Miles of pipe cleaned annually - 21
- Steet lane miles swept monthly - 346
The Tigard stormwater surcharge will increase by $3.50 on January 1, 2020 to fund enhanced stormwater management efforts in Tigard. After 30+ years without a guiding plan, the city now has a Stormwater Master Plan to address many erosion, water quality and flooding issues. Key projects getting underway soon:
- Kruger Creek Stabilization – Kruger Creek is experiencing severe erosion in the Bull Mountain area. This erosion is threatening slope stability and the safety of sewer, stormwater, streets and private infrastructure located near the creek. Design will start soon on needed stream improvements extending from Bull Mountain Park, under SW Greenfield and SW Gaarde Streets
- Frewing Street – Construction to replace undersized and aging stream culvert and storm pipelines will occur this winter.
- Red Rock Creek Stabilization – Planning is underway to define an extensive creek and greenway improvement project to address severe streambank erosion that has undercut sewer lines, plugged culverts and destroyed habitat through the Tigard Triangle. Creek stabilization and greenway enhancement, including a potential trail, will be designed and constructed over several years starting in 2022.
Money Saving Measures
Year-Round Maintenance - Staff work year-round maintaining Tigard water quality facilities to keep them functioning efficiently (these are ponds, swales and rain gardens that cleanse and slow down stormwater runoff before it enters pipes and creeks.
Major Maintenance – A regular program of proactive vs. reactive maintenance fixes things before they worsen, saving money and minimizing disruption.
