Public Works Maintenance <br /> List of <br /> Stormwater Rehabilitation Problems <br /> Requested for <br /> Capital Improvement Projects <br /> FY00 & FY01 <br /> December 1998 <br /> e , Brian Elliott, Jim McLaughlin <br /> The following is the current Stormwater Capital Improvement Project List provided by the Maintenance Technical <br /> Support section. This list (currently 23 items) is an active inventory compiled by the Maintenance Division to identify <br /> operationally -based problems with the public stormwater system. The list also provides Engineering staff with those <br /> problems, in order of priority, which have been determined by Maintenance to be an operational liability and best suited <br /> to be designed and bid as a capital improvement project. The current status of each item (problem) on this list is noted. <br /> Items will be removed from the list when they have gone "out for bid ". Please review this list and send any comments to <br /> Brian Elliott or Jim McLaughlin. Maintenance will continue to process any notable stormwater problems and will <br /> regularly distribute updated versions of this list. <br /> 1 of 23- Greenhill Tributary (Marshall Ditch) west of Terry St. N. <br /> o PWM Contact: Fred McVey <br /> o PWE Contact: Steve Gallup <br /> Current Problem:Four culverts ( #59950, 59951, 67062, and 70169) carry Marshall Ditch water <br /> under Terry Street and outfall to the Marshall Ditch on the west side of Terry. Two outfalls <br /> ( #70538 and 70559) to the west of the four culverts were installed to drain into the Marshall <br /> Ditch from Blair Commons Subdivision. The channel narrows significantly just west of the four <br /> culverts and is choked with trees and other vegetation, sediment and debris. This condition <br /> caused street and parking lot flooding at Daneland Mobile Home park on the east side of Terry. <br /> Efforts to correct this problem must be taken in `97. Due to the urgent need for channel cleaning <br /> work at this site, this should be considered the highest priority for channel cleaning funds. <br /> • Recommended Solution:Maintenance requests that this issue be addressed in two parts: <br /> 1) Use channel cleaning funds to complete cleaning and sediment removal from Terry <br /> Street to the City Limits. Also, assess the need and to what extent to reconfigure the <br /> ditch, if necessary, and contract out this portion of the work. <br /> 2) Acquire adequate easement access for maintenance within the BPA right -of -way <br /> along the south side of the Marshall Ditch for long term Maintenance needs. <br /> • Status: New Project 3/97. <br /> • Date identified as a CIP: (March `97) <br /> 2 of 23- Amazon Creek at Danebo Avenue Bridge <br /> o PWM Contact: Dave Ritter <br /> o PWE Contact: Therese Walch <br /> Current Problem: Accumulation of sediment and establishment of vegetation has created a <br /> large, mid - channel island just east of the bridge. The island has reached a size where it is a <br /> hydraulic impedement and could possibly lead to creek flooding in this area during major storm <br /> events. <br /> • Recommended Solution: Put this out to bid as a channel cleaning project to be done in <br /> the most environmentally sensitive manner possible and in compliance with Corps and <br /> DSL regulations. <br /> • Status: New to the CIP List. <br /> • Date identified as a CIP: (Nov. `98) <br />
