00416stripped. Ms. Charleson explained the tree cutting restrictions. Tom Archie of.9311 S.E. 36th St., Mercer Island the developer, stated that the previous proposal at this location had been for approximately 30 units, and he was proposing only 13. He said it was not economically feasible to run a sewer line from the available line to the property, and that it also was not feasible to hook up to Lynnwood. He said they had consulted with Warren Williams, a King County soils engineer, who had percolated the land and found it satisfactory for septic tanks. Mr. Archie said he could put in 23-30 units if he cut down a lot of trees, and the question was whether they had a good development or destroy trees and topography. Mr. Archie stated that Mr. Allen had never said sewers would be required, and if they were required he would not stay down to 13 one -acre lots. He said there was no way to retain the character of the land and have sewers. He asked that the proposal be considered with septic tanks instead of sewers. City Attorney Wayne Tanaka read Section 12.10.050 of the Edmonds City Code which requires connection within 800' of a sewer, and Mr. Allen commented that this .is within 20'-30' of the Lynnwood sewer line. Donald Coffin of 6727 163rd P1. S.W. said the ground at the site slopes tremendously and to put in a drain field would appear impossible. He said he could not believe they would consider septic tanks in that area. Commissioner Dickson commented on the places.all around the City where the ground had percolated well and as development progressed the percolation deteriorated. Warren Williams, stating he is a registered sanitarian in the State of Washington, said he had been doing perc tests in King County for 10 years. He described the soil on this property and said it percolates well, and that if the property were developed with the minimum number of houses and were not cut and terraced there would be no problem of percola- tion failure. He said the soil would perc according to Snohomish County requirements. Rick McArdle-said he helped to design this project and that the houses will be on a hilltop surrounded by a greenbelt. He said the other 50% of'the land will absorb the effluent. Commissioner Dickson said he, was concerned for the people on the other side of the road from this site. Mr. Williams said that when water travels underground, after it travels 100' the organic matter in it is nil. The public portion of the .hearing was.closed. COMP1ISSIONER SITTAUER MOVED -THAT PRD-3-77 BE APPROVED,,WITH THE•:RECOMMENDA- TIONS4F'THE CITY ENGINEER, AS THE CONCEPT OF THE PRD,WAS VERY,GOOD AS-,,` COMPARED TO THE PREVIOUS PROPOSAL FOR THE SITE,,AND AS HE DID NOT_BELIEVE THE PLANNING~'COMMISSION COULD RESOLVE THE SEWER PROBLEM. COMMISSIONER McGIBBON SECONDED THE MOTION. Commissioner McGibbon said he would like to see the Planning and Engineering Departments get together and prepare an analysis of recommendations made by the developers, taking into con- sideration what is best for the City, the large number of units or the sewers. He requested a position paper in the packets for the next hearing on this application. City Attorney Wayne Tanaka added that if they come in with a 25-lot subdivision, they will still have to meet the requirements of the subdivision code. THE MOTION 1HEN CARRIED. ZO-7-77 Amendment to the Zoning Code, Sections 12.12.050 and 12.13.110, to allow detached dwelling units in a multi -family complex. Ms. Charleson said this proposal was to update the Code so that when a multi -family complex is being constructed where a single family residence already exists the builder will not be required to attach the two struc- tures. This had been the requirement, sometimes resulting in an aesthetically unpleasing complex. Ms. Charleson indicated this change would create no significant environmental impacts. The public portion of the hearing was opened, no one wished to speak, and the public portion was closed. Ms. Charleson added that all apartment buildings go before the Amenities EDMONDS PLA14NING COMMISSION Page 3 - July 27, 1977 •1 em
