• • Impervious Surface Coverage The Plans contain no calculations regarding impervious surface. Building areas are included, but summaries of areas devoted to parking are not included. Rough calculations indicate that about 194,000 square feet will be covered by impervious parking lots or access drives between parking areas. This area, added to the area for the buildings (111,500 square feet) results in 305,500 square feet or 7.01 acres of impervious surface. Seven acres represents 17.3 percent of the site. The Ordinance states that in "no event shall off - street parking space, structures of any type, buildings or other features cover more than eighty -five (85) percent of the lot area resulting in less than fifteen (15) percent pervious surface. The Proposal meets the impervious surface requirements, but the Developer must realize that the amount of impervious capacity used up in this development will affect future usage of the remainder of his parcel. Building Requirements The building requirements are contained in Section 3, Subd 4 (B) (4). The proposed structure is by its nature unusual and, as proposed, would consist of two related but highly different structures. The inflatable dome is nearly impossible to vary; it is a white structure made of durable plastic and canvas. The second attached structure is a brick building like a large residential unit. Given these limitations, it would be impossible to meet the requirements (a) for "essentially the same or a coordinated harmonious finish treatment." The Ordinance further directs (b) that "exterior wall surfaces may be a combination of materials including brick, pre -cast concrete panel...." The entranceway and restaurant certainly meet these requirements, while the inflatable portion of the structure does not. It is common for these structures to be configured with a front entrance of stone or other building material to soften the effects of the stark, white structure. No metal panels are proposed for this structure (c), and earth tone colors are proposed for the restaurant portion of the building (d). From the architect's sketch, it appears not more than 10 percent of the building facade is in contrasting colors (e) and a condition of the project should be that all air conditioning or blower units on the property shall be screened. Since, by its nature, the proposed complex cannot meet all the specific building requirements of the Ordinance, it is recommended that the project be viewed as a whole with extensive use of landscaping, especially the planting of trees, to create visual interest around the structure. Buffers The Lino Lakes Zoning Ordinance states that "where a side or rear lot line in an LI District coincides with an adjacent residential or commercial district, or public road right - of -way, a landscape buffer area shall be provided along such side or rear lot line not less 12701 -002
