DRAFT 1/5/95 2. Dwelling units or sites, road rights-of-way, or land covered by road surfaces, parking areas, or structures, except water -oriented accessory structures or facilities are developed areas and shall not be included in the computation of minimum open space. 3. Open space must include areas with physical characteristics unsuitable for development in their natural state, and areas containing significant historic sites or unplatted cemeteries. 4. Open space may include outdoor recreational facilities for use by owners of dwelling units or sites, by guests staying in commercial dwelling units or site, and by the general public. 5. Open space must not include commercial facilities or uses, but may contain water -oriented accessory structures or facilities. 6. The appearance of open space areas, including topography, vegetation, and allowable uses, must be preserved by use of restrictive deed covenants, permanent easements, public dedication and acceptance, or other equally effective and permanent means. 7. The shore impact zone, based on normal structure setbacks, must be included as open space. For residential PDO's, at least fifty (50) percent of the shore impact zone area of existing developments or at least seventy (70) percent of the shore impacts zone area of new developments must be preserved in its natural or existing state. For commercial PDO's, at least fifty (50) percent of the shore impact zone must be preserved in its natural state. E. Erosion Control and Stormwater Management. Erosion control and stormwater management plans must be developed and the PDO must: 1. Be designed, and the construction managed, to minimize the likelihood of serious erosion occurring either during or after construction. This must be accomplished by limiting the amount and length of time or bare ground exposure. Temporary ground covers, sediment entrapment facilities, vegetated buffer strips, or other appropriate techniques must be used to minimize erosion impacts on surface water features. Erosion control plans must be in accordance with the Lino Lakes Local Water Management Plan and approved by the City Council. 2. Be designed and constructed to effectively manage reasonably expected quantities and qualities of stormwater runoff. Impervious surface coverage within any tier must not exceed twenty-five (25) percent of the tier area, except that for commercial PDO's thirty -fie (35) percent impervious surface coverage may be allowed in the first tier of general development lakes with Page 31
