'toning File #991 S #1018 May 6, 1986 Page , of. 4 Planning Coirunission Recommendation - To deny the quest to install 6 feet high berms along the street/lot line and to complete the restoration of the road right-of-way and the entire area restored to its original state. Area (4) Major filling between Ulrich and former Blohorn properties - re�€er to exhibits 0 & P. Clearly the filling within the Ulrich property 30 feet north of the original dividing line was not approved with the building permit. The original showed the lower elevations of 938 - 940 (remains of the old bowl area) that funneled drainage down to the lake. The plans approved with the building permit and current proposal show a decrease in drainage towards the lake and a shift in approximately 1.24 acres of drainage area to the ponding area to the south (see Exhibit J). Per Exhibit L, the applicant's engineer in his summary (page 3) notes the increase in runoff to the pond would raise the pond level 0.4 feet in a 100 year storm and finds no appreciable effects on retention pond. The M.C.W.D. does not require permit review for the proposed shift in drainage. The applicant's consultant claims little effect on the pond and local watershed. Cook states (Exhibit M) the final grading plan is superior because the east 1/3 of the property drains to the pone. before entering the main lake. The plans appr-ved with the building permit provide for grassed slopes ranging from 94b to 938' elevations within 51 feet along the southern yard area (15% grade) Exhibit 0. Drainage from both the former 9lohorn and Ulrich properties would drain down to the 938 elevation and out directly to the lake. The original banks along the north side of the Blohorn property would be much steeper than those proposed on the Ulrich side of ;ghat would h-,ve become a ra�yine area. I hav--_� asked Cook to comment on the current plans proposed by the applicant. Fie contends the uniform or f. latrar grades and gentle grassed slopes to lagoon provides a more suitable treatment area for surface drainage. We both agree the original bowl area was ideal - providing retention and flat grassed areas for surface wat-r treatment but the house now resides in the bowl area.
