TO: Planning Commission FROM: Jeanne A. Mabusth DATE: January 28, 1982 SUBJECT: 4669 Tonka Lake I'--operties, 1340 Baldur Park Road Subdivision Application - Subdivision - 4 lot plat Variances 1) density credit 31.841 (c) 2) hardcover 0-75' 75'-250' List of Exhibits Exhibit A - Application Exhibit B - Applicant's letter Exhibit c - Data table Exhibit D - 1978 plan Exhibit E - Preliminary plan Tonka Lake properties has filed a 4 lot plat subdivision application - note not a PRD - requiring variances and density credits. In the following review I have made chances in the applicant's data tables (See Exhibit B 6 C). I requested that the pre- liminary plans for the formal application designate the flood plain elevation of 931.J as in Peterson's 1.978 application. (Exhibit D) If you review the preliminary plans from application 4466 the 931.5 elevation would take approximately 3,300 sf from the buildable envelope area noted by the applicant at 25,300 sf based on the 932 elevation. The allowed buildable area at the 75' setback area would be changed from 6,325 sf to 5,500 sf. In addition I have amended the total proposed hardcover calculation for the 0-75' setback area from 10,260 sf to 11,040 sf. The applicant was asked to designate a road with a minimum width of 18' and he has designated 16'. This 2' difference created an addition of some 780 sf of hardcover and changed the total hardcover for the revised plan to 18,680 sf. Brief Review The plans still show indiviUual riparian outlots. Based on the limitation of the site, I would still suggest one shared riparian outlot with a single joint use dock whether you recommend a 2, 3 or 4 lot plat. Rouses can be placed on each newly created lot meeting all required setbacks. Lot 4 may have some difficulties once the 931.5 elevation is designated - once again check the Peterson plan of 1978.
