A. These guidelines deal with single-family residential (R1, R2, RA-2, R3, R5) areas as well as areas designated hillside residential (HR) and rural residential (RR). They strive to improve the quality of life for single-family housing residents, to ensure attractive single-family neighborhoods and to offer solutions to recurring design problems.
1. R1: provides for and protects the rural lifestyle by having large residential lots and the keeping of large animals.
2. R2: provides for suburban lifestyles on residential lots larger than commonly available in suburban subdivisions, and to allow residential developments in a rural atmosphere.
3. RA-2: provides for suburban lifestyles on residential lots larger than commonly available in suburban subdivision, and for the keeping of animals that have historically characterized these areas.
4. R3: provides for a transition between rural and urban density development areas and provides for suburban lifestyle on residential lots larger than those commonly found in suburban subdivisions.
5. R5: provides for single-family detached housing on common-sized suburban lots.
6. Hillside residential (HR): balances the preservation of hillside areas with the development of view-oriented residential uses. These include large lot residential, and single-family residential on lots larger than 20,000 square feet.
7. Rural residential (RR): provides for the protection of the rural lifestyles, as well as protects natural resources and hillsides in the rural portions of the city. Within the rural residential area large residential lots are appropriate and the keeping of large animals shall be permitted.

R5 | 5 units/acre |
B. General Guidelines.
1. A combination of a wall and bermed landscaping shall be provided adjacent to the rear or side yards of lots at neighborhood entries.
2. Residential units should be provided with a minimum five feet variation in their front and side yard setbacks along the streetscape.
3. Residential units shall be articulated and detailed to provide visual interest and scale by using a minimum of three of the following design elements.
a. Provide projecting and/or recessed entries and windows.
b. Include projecting or recessed balconies.
c. Front porch with a minimum depth of five feet.
e. Minimum 18 inch roof overhangs with detailed rafter tails.
f. Offset building planes a minimum of two feet.
g. Stepping back a portion of the second story.
h. Use of different building materials with varying textures and colors.
4. All units shall be designed with four sided architecture using the details from the front elevation.
5. Increased setbacks shall be provided on lots that are sited at corners or have rear yards bordering an arterial roadway.
6. Home builders shall consider the after-market construction of patio covers; room additions or second-floor balconies by providing ample rear yard setbacks. Rear yards shall be designed with minimum of 15 feet of flat areas adjacent to the structure.
7. Residential projects should maximize the feeling of openness by curving streets, varying front and side yard setbacks and, if possible, orienting roads to open space areas and views.
8. Small lot single-family subdivisions should utilize innovative design techniques to provide more usable and private exterior area.
9. Residential mechanical equipment, including but not limited to air-conditioning units, shall be screened with walls and landscaping from surrounding properties and streets and shall not be located in the required front yard or street side yard.
10. Storage of recreational vehicles, boats and campers should be provided for residents by either an enlarged side yard setback to allow access to the rear yard or an off-site storage area, both of which are to be out of public view. Residential units should be designed with the larger side yard, a minimum of 10 feet, on the garage side of the structure for storage/yard access. Pervious surfaces are required for such areas within required setbacks.
11. Driveways shall be placed to maximize off-street parking opportunities and still maintain minimum landscape requirements. Pervious surfaces are recommended where feasible.
12. Mailboxes, if required to be clustered, shall be designed to be compatible with surrounding homes, while conforming to post office guidelines.
13. Property lines shall be located on the tops of slopes.
14. Natural topographic variations should be retained to divide residential developments into distinct neighborhood areas.
15. Within individual residential projects, a variety of floor plans and elevations should be offered as follows:
Table 9.16.130B |
|---|
Number of Units | Minimum # of Footprints | Minimum # of Elevations/ Footprints |
|---|
5—9 | 1 | 2 |
10—24 | 2 | 3 |
25—49 | 3 | 3 |
50 plus | Add one additional footprint for every 50 units over 50 | 4 |
Each floor plan shall not be repeated more than each fourth house. Please note that adding or deleting false shutters or similar types of minimal elevation changes will not suffice as one of the required distinct elevations.
16. To minimize visual impact, corner residential units shall be single story or if two story, shall incorporate single story elements into the design. The short and low side of the unit should be sited toward the street corner.
17. Automatic garage door openers shall be required to be installed in houses with less than a 20 foot front setback. Garage doors with windows shall be required for three or more car garages or other architecturally enhanced garage doors or as approved by the community development director.
18. Fence and wall materials should be durable and architecturally compatible with the neighborhood appearance. Walls and fences constructed of slump stone, stucco-coated block or wrought iron are encouraged. Fences and walls constructed of nondurable materials, including but not limited to plywood and chicken wire are prohibited. A front yard fence or wall shall be erected in a manner that does not obscure visibility through the fence or wall.
