The plan which showed the revised court location, as approved by the Planning Commission, was not approved by the Council, since it showed only that portion of your property on which the proposed paddle tennis court is to be located. A full plan of the property, showing all improvements, is required for the file. Mr. McHattie of South Bay Engineering has been advised of the requirement. The plan shows a five foot high retaining wall, which is not in compliance with the Planning Commission's require- ment that retaining walls: incorporated as a part of the overall plan of the court shall not be greater than four feet in height. (Section 17.16.012 F(11), Rolling Hills Municipal Code. ' It has come to the attention of this office than an existing stable on your property is being modified by addition of windows. This is in violation of Section 17.16.050 of the Municipal Code, which specifies that no building shall exceed one story in height except a barn or stable which may have a loft without glazed openings to be used exclusively and only for the storage of feed, tack and stable equipment. •The Department of Building and Safety has been requested to place a notice on your property that all work on the stable is to cease until the matter has been resolved. The Rolling Hills City Council will hold a special meeting at 7:00 A.M. Friday, March 16, 1984 to review the plans for your property, pursuant to Section 17.32.140 of the Municipal Code.

This information consisted of a quantitative runoff analysis and a topographical map indicating existing and proposed drainage facilities. The additional and previously submitted data have been reviewed and field checked by this office. The field check was conducted to verify topograph- ical data and investigate possible erosion problems on site and in the down- stream canyon areas.

X feel that careful consideration should be given to the erosion of the canyon floor west of Buggy Whip Dr., which canyon drains the property under consideration. I have noticed an increased flow of water with resulting erosion as the ground cover has been removed from the properties at #8 and #2 Buggy Whip Dr. The erosion has been prevented from cutting into the property at #8 by placing in the streem flow at the canyon bottom a large quantity of concrete pieces. While this will reduce the headward erosion, the downstream erosion remains. I•suggest that the Planning Commission consider the increase in peak water flow which will be caused by replacing the semi absorbent ground with a totaly'impermiable paddle tennis court. Additionaly I notice that the drawing indicates a possible swimming pool with surrounding deck area. This also will contribute to the peak water flow. I suggest that the Commission members look at the canyon bottom by walking (riding their horses?) along the trail from Hix Ring to Johns Canyon R. r L., . • guuPOR..1'14.L.- 6 - Charles E.

Dear. Mr. Smith: As discussed by phone this date, we are advising you that the subject additions to the S.M. Kim property does not significantly change or alter the surface water regimen downstream from the subject site. As discussed in the previous report by Michael Scullin, Project #82111, April 22, 1982; the riding ring also acts as a desilting basin that collects silt and allows the water to pass thru. Mr. Kim is probably one of the few or the only one that has such a flood control structure or device on their site. The swimming pool and the paddle tennis court are proposed to be constructed up the slope and out of the water course. They will not significantly contribute to the increase in water runoff. The residential area was stabilized with a buttress fill under inspection of Pacific Soils Engineering Inc. This office has made recommendations for the safe design of retaining walls to support the pool and paddle tennis court. These should provide adequate safety against sliding within the site. Geology • Soils • Concrete • Masonry • Steel Mr. Ron Smith, City Manager December 20, 1983 Job No.: 2122-00, Log No.: 6929 Page 2 Whatever water that runs off the site thru the desilting basin has always been contributary to the water course downstream.
