The sewer line referenced in your memorandum dated June 19, 1979 is for the Viewpoint Subdivision north of the subject property. Tryck, Nyman and Hayes reports that they are currently working on engineering plans for the sewer. They are also negotiating a subdivision agreement for sewer with the Municipality. The developer of Viewpoint will likely request that his sewer connect with the Municipal sewer in Oceanview. Discussions towards this end have not begun. Tryck, Nyman and Hayes also reports that there is no agreement between the developer of Viewpoint and Steve Hagedorn or HVL to extend the sewer to the subject property. Thus, the developer of Viewpoint intends to construct a sewer to his property. Whether this will actually occur in 10 years is another question -- particularly in light of the fact that he intends to con- nect with the Municipal sewer. Also, the Planning Department will likely recommend R-8 zoning for the subject property in the Area G-5 Areawide Zoning. Thus, we find it difficult to recommend one acre lots on the subject property without a strong concurrence from the Environmental Health Division. In all four test holes, the driller found either bedrock or ground water. Granted larger lots may not solve the problem, but larger lots will minimize the problem and will tend to limit development until public sewer and/or water is available. In light of these comments, do you still recommend approval of the plat as submitted? ` DS/NW/cros 91.010 (4/76) L) Luab ErIN � PLt�t QA &L S - s.16a 11 DEPARTMENT OF HEALTH AND ENVIRONMENTAL PROTECTION ZONING CASE REVIEW In, PLATTING OR PLANNING AND Z Y J j l/ CASE NUMBER 5-5162 J4� 't-t'E PETITION FOR REZONING SPECIAL EXCEPTION VACATION RESUBOIVISION DATE RECEIVED May 2, 1979 - per- ILA�' OF Tract 14 The Villages Subdivision COMMENT TO PLANNING BY May 18 / 1979 FOR MEETING OF of Cases COMMENTS: ENVIRONMENTAL SANITATION: PUBLIC WATER NOT AVAILABLE PUBLIC SEWER NOT AVAILABLE TO SERVICE PETITION AREA, ENVIRONMENTAL ENGINEERING: 71014 (9/76) Planning and Zoning Department May 16, 1979 Page Three S-5153: Lots D-1, D-2, D-3, C-1 Teri Subdivision '2 Environmental: Sanitation - This department has reviewed the subject lots and sho•.:s soil in Lots D-1 and D-3 to be adequate to support on-site sewer systems.

However, this Department requests Engineering recommendations for location of on-site septic systems to be on file at the Department of Health and Environmental Protection so as to assure proper closing of the systems per lot. This Department finds this will meet conditions with which this Department is concerned. RS:lmp III 45
