00415i PRD-3-77 would be built on the site. He was advised it would not and that this had been covered previously at the contract rezone hearing. The public portion was then closed. COMMISSIONER McGIBBON MOVED, SECONDED BY COM- MISSIONER HALL, TO APPROVE SM-2-77, SUBJECT TO THE CONDITIONS OF THE CONTRACT REZONE AND RECOMMENDATIONS OF THE STAFF. MOTION CARRIED. PARKSIDE DEVELOPMENT COMPANY - Planned Residential_ Development 13 dwelling units on N.'Meadowdale:Rd. near 68th Ave: W. and 164th St..S.W. Ms. Charleson said this was a preliminary review to be followed at a later date by the design review. The site is in north Edmonds and is bounded on the west by Meadowdale Rd. The site is heavily wooded and slopes substantially to the west. There are two cul-de-sacs which are located on flat knolls with a steep ravine between them. The area .is large enough for 25 building lots, but 13 are proposed. Zoning is RS-20 to the north, south, and east, and RS-12 to the west. She showed the location on the Comprehensive Plan and Zoning Map and showed slides of the site. She said each owner.will own 1/13 of the common open space, thereby preserving most of the vegetation on the site. A proposal was submitted in 1975 for this site which was for approximately 30 units but that proposal was not developed. Ms. Charleson noted that there are no interior setback require- ments in a PRO, but each unit will be at least 25' from another and the units will be detached. One of the requirements the Planning Department will make.will be that a soils engineer give a soils report on the existing conditions there because there have been slide conditions in the area. Ms. Charleson noted that the applicant will be requesting a 20, paved street, rather than the required 24'. She said the developed areas and the road equal approximately 50% of the site, leaving 50% open space (25% open space is required). A crushed rock walk is required on 68th . and two fire hydrants are required. Connection to sanitary sewers will be required. The applicant proposed that the entire site drain into a detention pond. Ms. Charleson said no environmental.findings could be made until there is more information -on the soil condition and on drainage. She recommended approval on a preliminary basis. Chairman Naughten noted that there should be some safety measures taken if the detention pond is very large. The public portion of the hearing was opened. Jerry Krell of Kegel & Associates, the project designer, said the detention area would be only for excessive storm water and that they generally create such areas no deeper than 18"-24" so as not to create a danger or an attractive nuisance. He said the detention area generally would be dry, except during heavy rains. Regarding a crushed rock walkway, he said he would not want to do a lot of grading or removal of trees for a walkway. Assistant City Engineer Dick Allen remarked that the gravel walkway would be a minimum disturbance of the site. Fred Kefgin noted that on the Westmont View plat, across from this site, there is also a holding pond and exposed aluminum piping. He said he hoped that kind of piping would not be installed on this site. He inquired whether all the houses would be high enough to drain to 68th, and Mr. Allen responded that they would not but they could be pumped up. Mr. Krell then said that any progress on this development will be hampered by the sewer requirement. His proposal was to service each lot individually with septic tanks in order to avoid the piping, cutting, clearing, and costs of providing sewers. Mr. Allen said his recommendation would be denial on that basis, that sewers are a City requirement and that the only unusual requirement here was the necessary agreement between the Cities of Edmonds and Lynnwood for sewers. He added that the Health Department had already issued letters to the City recommending no more septic tanks in this area. Fred Kefgin called attention to the fact that there were tree cutting restrictions on the development across from this but three lots were EDMONDS PLANNING COMMISSION Page 2 - July 27, 1977
