8 “Placement of structures on lots. When more than one setback applies to a site, structures and facilities must be located to meet all setbacks. Where structures exist on the adjoining lots on both sides of a proposed building site, structure setbacks may be altered without a variance to conform to the adjoining setbacks from the ordinary high water level, provided the proposed building site is not located in a shore impact zone.” The plans show the 883.7 OHWL; however, staff understands this elevation was not field surveyed and may not be accurate. Therefore, the setbacks of houses on the adjoining lots cannot be verified. The February 11, 2008 Council Report states the house at 6697 Ruffed Grouse is 70.6 feet from the OHWL and the house at 6690 Ruffed Grouse is 90.5 feet from the OHWL. The average of the 2 setbacks is 80.55 feet and this would be the allowed setback from the OHWL. Unfortunately, this information may not be accurate and must be field surveyed and recalculated. The Preliminary Plat Plan Sheet 04 incorrectly shows the 75 foot shore impact zone as the allowed setback. The proposed house plan encroaches into the previously approved 80.55 foot average setback. Again, this information needs to be verified and recalculated. The plan sheet also incorrectly labels the 75 foot shore impact zone as the Upland Boundary. The Grading Plan indicates 2.31% impervious surface coverage which meets the allowed 30% impervious surface coverage of the shoreland ordinance. Comments: 1. The 883.7 OHWL shall be field surveyed and shown on the plans. 2. The actual house setbacks to the OHWL of 6697 Ruffed Grouse and 6690 Ruffed Grouse shall be shown on the plans. 3. The average of setback line of theses adjacent houses shall be shown on the plan. 4. The 75 foot shore impact zone shall be clearly marked on the Preliminary Plat Plan Sheet 04 and Grading and Utilities Plan Sheet 05. 5. The Upland Boundary label shall be renamed Contiguous Buildable Area. 6. The Contiguous Buildable Area shall be shown and calculated 10 feet outward from the delineated wetland boundary. 7. The civil plans and house plans shall be revised to meet the accurately calculated average setback. 8. On the Preliminary Plat Plan Sheet 04, it shall be included under Notes that all structures (decks, accessory structures etc.) shall meet the required OHWL setback. Final Plat A land use application for final plat and Development Agreement shall be required. RECOMMENDATION The Planning & Zoning Board held a public hearing on June 14, 2017. There were no public comments. The Board voted 6-0 in favor of the preliminary plat.
