#932 Edwards Page 2 June 24, 1985 Now, looking only at the building site, note that we have to deal with two 75' setbacks. The hardcover numbers presented by the applicant's surveyor take into account only the lake setback, not the lagoon setback. Hence, the total area of the building site within 0-75' of shoreline is actually 18,750 square feet, with only about 11.250 square feet in the 75-250' setback area. This mathematically raises the 75-250' hardcover percentage but lowers the 0-75' percentage. Technically, considering only the building site, 0-75' proposed hardcover is 2,960 square feet or 15.8%, and in the 75-250' zone is 3,380 square feet or 30.0%. The next point to consider, then, is which direction will the hardcover drain to. It should be directed to the north, so that in the case the variance is granted, drainage from the house and driveway will travel over or through 100 feet of lawn area before reaching the lake. If all runoff can be directed to the lagoon, the following hardcover numbers would apply: 0-75' = 9,375 sf total area 75-190' = 14,375 s.f. total area 0-75' (lagoon) existing driveway = 1,400 sf (15%) 75-190' (190' is the proposed drainage break) House 2,800 + sf Deck 360 + sf New Driveway 1,200 + sf Sidewalk 60 + sf Existing driveway 520 + sf Total 4,940 sf (34%) 0-50' (lakeshore) 0 hardcover = 0% This method of calculating hardcover northodox but accomplishes exactly what we are striving for in our ioff infiltration concerns, i.e. it meets the intent but not the letter of the code. Next, consider the average setback issue. Because the neighboring owners have stated that they value the views of both their lake and lagoon yards, they also request that the new house conform Pssentially to the setback of the existing houses. Although the average "line of sight setback" would be about 35' from the lakeshore due to the curvature of the lake, the mathematical average setback is 49.5'. As you can see from the survey, the applicants garage will encroach on site lines toward the lagoon. Based on the above facts and conditions, staff would suggest that: 1) The lot is buildable without a lot area variance because we are allowed to credit the non-contiguous dry buildable across the lagoon for a total of 1.7+ acres. 2) The actual area to be permanently credited should be enough to bring the lot area up to either 0.8 or 1.0 acre and this: crediting become a clause of the final resolution, so that any future development of the northern portion of the property does not negate this credit. (Planning Commission recommended no permanent credit required.)
