RESOLUTION NO. /9'4. O A Resolution declaring an emergency to exist and authorizing the Operations and Maintenance Division of the Public Works Department and a private boring contractor to replace an existing 18" concrete drainage culvert with a 30" steel drainage pipe plus necessary dirt and rock fill and 30" extension corrugated steel or aluminum drainage pipe and necessary clean up work located on Mukilteo Blvd. between Lynnwood Drive and the Merrill Ring Bridge at an existing drainage draw. WHEREAS, on the night of May 9, 1981 around midnight or 1 :00 a.m. on May 10, 1981 an 8" A. C. water line broke adjacent to the gulley located between Lynnwood Drive and Merrill Ring Bridge on Mukilteo Blvd. causing the gulley to fill up with water, mud, sand, and debris, and as a result of this, the existing 18" culvert plugged up tight and collapsed approximately 26 lineal feet from the end of the tile on the north side of Mukilteo Blvd, and WHEREAS, there has been a problem for several years with road settlement at this location that we feel was due to the leakage of the existing 18" tile or a partial tile failure, and WHEREAS, the water line break with the very heavy water flow with debris and muck finally caused the total failure of the existing 18" tile, and WHEREAS, the 18" tile is totally unusable now and something has to be done soon to correct this water buildup behind Mukilteo Blvd. , or there is a possi- bility of washing out Mukilteo Blvd. and causing considerable damage to the B. N. Railroad main line to the north and down stream of this location, and WHEREAS, the City Sewer Division is pumping the water out to keep the pressure down on a 24-hour-as-needed schedule, and WHEREAS, the Sewer Division does not have the necessary large equipment to perform this kind of tile replacement, since the tile is located approximately 30' deep at the south end and approximately 50' deep at the north end, and WHEREAS, there are two possible methods of replacing this drainage tile, ONE being to hire a large one yard or more drag line to excavate the broken section out, replace the damaged tile, excavate out the upper end to open up the existing 18" tile, backfill , compact, replace existing asphalt, cleanup at a cost of approximately $70,000, and WHEREAS, this method would CLOSE Mukilteo Blvd. for at least a week causing problems of many kinds, and WHEREAS, the second method is to emergency contract with a boring contractor to bore and place a 30" steel culvert pipe under the boulevard with City crews completing all other necessary work to finish the project without closing Mukilteo Blvd. except for one lane traffic for several days during working hours at an approximate cost of $50,000, for the total project, and
