and shall not be included in the computation of minimum open space); 2) open space shall include areas with physical characteristics unsuitable for development in their natural state, and areas containing significant historic sites or unplatted cemeteries~ 3) open space may inc1ude outdoor recreational facilities for use by owners of dweUing units or sites, by guests staying in cOJJUJ\erical dwemng units or sites, and by the generaJ public; 4) open space shall not include commercial facilities or uses, but may contain water-oriented accessory structures or facilities; 5) the appearance of open space areas, including topography, vegetation, and allowable uses, shall be preserved by use of restrictive deed covenants, permanent easements, public dedication and acceptance, or other equally effective and permanent means; and 6) the shore impact zone, based on normal structure setbacks, shall be included as open space. For residential POOis, at least 50 percent of the shore impact zone area of existing developments or at least 70 percent of the shore impact zone area of new developments shall be preserved in its natural or existing state. For commercial POO's, at least 50 percent of the shore impact zone shall be preserved in its natural state. 18.085.75 Erosion Control and Stormwater Management. Erosion control and stonnwater management plans must be developed and the PUD shan be: 1) designed, and the construction managed, to minimize the likelihood of serious erosion occurring either during or after construction. This shall be accomplished by limiting the amount and length of time of bare ground exposure. Temporary ground covers, sediment entrapment facilities, vegetated buffer strips, or other appropriate techniques shall be used to minimize erosion impacts on surface water features~ and ")'1 1'1",.:.; r'tn"''¡ ..nl'l 1"I',n.:.t....i"tA'¡ tl'\ AR"Ai"t:...."T" ""'..,..,1:1....... rAQ""......ht.., ."v......"..t"'r! n\,!:u..t~t~..c, !:II,..,r! 6ÞJ ...........:U.;E:.l.iL....W. ~I......

Centralization and design of facilities and structures shall be done according to the following standards: 1) planned unit developments shall be connected to publicly owned water supply and sewer systems; 2) dwelling units or sites shall be clustered into one or more groups and located on suitable areas of the development. They shall be designed and located to meet or exceed the following dimensional standards for the relevant shoreland classification: setback from the ordinary high water level, elevation above the sunace water features, and maximum height. Setbacks trom the ordinary high water level shall be increased in accordance with Section 18.040 of this ordinance for developments with density increases~ 22
