KEN WICK 530 MAIILSBY EVERETT, WA. 98201 RE -Drainage tests pursuant to response dated 1/3/B6 and conversation on 1/23/86. Mr. Wick, The City of Everett sent a crew to check: the integrity of the public combined sewer and drainage system adjacent to Your property on 1/24/86. The crew installed a hydraulic plug on your side sewer and artificially flooded the system with water from the fire hydrant. The hydrant was allowed to flow unrestricted for approximately 30 minutes and during this period no physical sign of leakage was evident at 'our bulkhead. This is the location where you indicated that problems had occured during the past flooding experience. The City believes that this test confirms the suspicion that, the subsurface flow and basement leaking problems that have occured are the results of wastewater backing up in Your sidesewer and leaking through your pipe into the areas around the house and bulkhead. As we discussed earlier physical changes that would resolve all future flooding problems resulting from system back: up would be to install a check valve at or near your property line, replacement of your sidesewer where it is leaking, or installing a grinder pump and pressure line. You must weigh the advantages and disadvantages of each alternative and resolve which will best suit you needs. If you install a check: valve or a grinder pump it will require regular maintenance. If you have any question regarding these physical modifications please call me at 259-8821. Sincerely Alfred R.
