r #932 Ward Edwards Page 2 June 12, 1985 The critical and rational 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 ± New Driveway 1,200 + Sidewalk 60 + Existing driveway 520 ± Total 4,940 sf (31%) sf sf sf sf 0-50' (lakeshore) 0 hardcover = 0% This method of calculating hardcover is unorthodox but accomplishes exactly what we are striving for in our runoff 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 essentially 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 (Planning Commission — make a recommendation as to which) 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. 3) The lot width of 125' is greater then 80% of the required 140' width, so no formal lot width variance is required. 4) The drainage f rom the house should all be directed toward the lagoon in order to gain the maximum infiltration time and distance. 5) Based on item 4, the hardcover in the lagoon 75-190' zone is requested to be 4,940 square feet or 34%, requesting a 9% variance for a new home. Your task is to determine whether any hardships justify this variance.
