NB area established because the site is characterized by two rock outcrops that serve as a prime habitat for reptiles and other small wildlife species. 13 Primary Residence Artist Studio Walkway Access Road Primary Residence: edge encroachment with no rock outcrops/significant veg Artist studio: flat area with sparse veg and no rock out crops Walkway: area staff was really focused on, had concern because it appears as though you are bisecting the habitat. Staff really focused on connectivity for wildlife species. 14 Areas of encroachment Artist Studio Primary Residence Left: edge encroachment with scattered rocks. No rock outcrops or significant veg. Right: area with sparse veg and no rock outcrops. 15 Areas of encroachment Walkway Again, we had concern about the proposed walkway. However, after a site visit it was determined: The area for the proposed walkway Relatively flat area between the two rock outcrops w/ little to no vegetation After seeing the site, staff was okay with the walkway with a condition of approval added to ensure the walkway is cantilevered to allow for free movement of wildlife between the rock outcrops. Make sure the connectivity between the rock outcrops is not impacted. 16 New Open Space The new open space as part of the trade includes: Developable area that has: Small to medium rock outcrops Two mature saguaros! 17 Surrounding Area Blazing Canyon Drive Golf Course Golf Course Applicant’s proposal will have no visual impacts on neighboring properties.

Staff has not received any correspondence. 18 Summary and Recommendation Request consistent with: Rancho Vistoso Planned Area Development Zoning Code Staff recommends approval, with condition listed in Attachment 1.
