The proposed standards and proposed ADU both follow PMC Chapter 18.106 ADU standards with no deviations.

Height Maximum 15' and one-story 15' and one-story 0 13'-4" and one-story Parking Minimum One Space One Space 0 Two Spaces Site Design The proposed residence is set toward the rear of the lot, behind the existing residence. The proposed siting allows for a large front setback and generous side and rear setbacks, which are all consistent with the A-district (as seen in Table 1). The large setbacks are also consistent with the existing rural-residential streetscape and substantially mitigate the mass and scale of the proposed residence when viewed from Sycamore Road. The site design takes advantage of the existing driveway on the lot and automobile access to the new garage continues off the existing drive along the west side of the lot. Extensive site improvements such as new walkways, a pool, trellises, and raised planters are proposed throughout the site. The site improvements and proposed outdoor spaces relate well to the site's built features including the proposed residence and existing residence that is being converted to an ADU and are sensitive to the site's natural features including the existing vegetation. The proposed site design meets the NSSP guidelines in the following ways: As measured to the edge of the new right-of-way line. 6 As measured to the edge of the new right-of-way line.
