10 feet; and minimum side and rear yard setbacks of accessory structures greater than 15 feet in height and/or 100 square feet in area - 20 feet. IV. Design Guidelines. Happy Valley architectural design is generally informal in character and reflects the agricultural heritage of the neighborhood. The Valley contains a rich diversity of lot patterns, building siting, landscape design, and open space elements which the PUD-SRDR District strives to preserve. The design objectives of the PUD District are to: maintain the area's existing semi-rural character; maintain the open-space feeling between adjacent homes and other structures; minimize the visual prominence of homes; and encourage diversity in landscape design. The following guidelines should be followed to the greatest extent practical. IVlinor variations may be permitted during the development application review process provided that any variation substantially meets or exceeds the objectives contained herein. 5~.-elaaai~: Placement of new structures and additions should be sensitive to conditions on nearby properties and should not adversely impact open space views and the semi-rural character of the area if other reasonable site layout and design options are available. (1) New principal structures (homes) and other structures should be sited to minimize impacts on neighboring properties. (2) House entries and porches should be oriented to adjacent roadways. (3) Accessory structures detached from the main house are encouraged. (4) The width of principal structures (homes) should be limited to not more than 50 percent of the lot width. Development on narrow, deep lots should emphasize structures with narrow width dimensions along the parcel frontages. (5) Grading for development of hilly areas in the vicinity of Happy Valley Road should respect the natural land forms. (a) Grading should be limited as much as feasible. Pads for structures and yard areas should be stepped with the hillside slope rather than creating large fiat areas to accommodate structures on the same level. (b) Grading which modifies the tops of hills and/or interrupts natural hill forms should be avoided whenever other reasonable alternatives are available. (c) Where cuts and fills are necessary, contour grading shall be used which blends new grades with existing ones. Straight and geometric lines on graded slopes should be avoided. (6) Home sites should be clustered where appropriate to preserve open Page 4 of 8
