Increase capacity of storm water collection systems to accommodate projected changes in precipitation. Backup and overflow of storm water facilities from heavy precipitation events, especially during high tide periods, may become more frequent under future climate scenarios. Preventing local flooding as a consequence of inadequate storm water facilities can be prevented by increasing detention storage in areas prone to failure. As discussed previously, Whatcom County is responsible for the maintenance of most of the roads and associated storm water drainage systems on the Reservation. However, the Lummi Nation may also make improvements to storm water infrastructure as necessary.
