Gaffron, Asst. Planning & Zoning Administrator <br />May 18, 1992 <br />Shore land Ordinance - Response to DNR <br />List of Exhibits <br />Exhibit A - Proposed Letter of Response <br />Exhibit B - Memo and Exhibits of April 8, 1992 <br />Council will recall that the DNR's response to our Shoreland Ordinance <br />requested additional justification in two areas: <br />1. Definition of "steep slope" at 18% versus DNR's 12% <br />definition. <br />2.10' setback for lock boxes. <br />On April 13th, Council dir "'■ed staff to review the background behind <br />the City's 18% "steep SxOpe" definition and report back. <br />Additionally, Council indicated that there clearly were some <br />locations where a 10' lock box setback from the OHWL is not reasonable <br />or feasible, and we should make this point to the DNR. <br />Steep Slopes <br />Until the recently enacted Shoreland Ordinance, Orono had no strict <br />definition of steep slopes. In fact, references in the zoning or <br />subdivision code regarding steep slopes until 1984 was limited to an <br />additional building height allowance on lots of 25% slope or steeper. <br />In April 1984 a new subdivision code went into effect, and within its <br />definition section, "dry buildable land" was defined as excluding <br />drainageways, flowage areas, flood plains, wetlands, marshland or <br />slopes of 18% or greater. However, the only other reference in the <br />subdivision chapter is a general section abo c the "character of the <br />land", which <rlves Council discretion to find land to be "unsuitable <br />for development" due to, among other things, steep slopes (but does <br />not define "steep slopes"). <br />While the 1980 Comprehensive Plan makes a few references to the <br />preservation of slopes from both an aesthetic standpoint as well the <br />need to maintain vegetation to limit erosion, there is no directive <br />that slopes over a certain percentage will be considered as <br />unbuildable.
