13.36.100 - Driveways and site access.
Each driveway providing site access from a street, alley or other public right-of-way shall be designed, constructed and maintained as follows:
A. Number of Driveways.
1. Multifamily and Nonresidential Projects. A multifamily or nonresidential project on a parcel of two acres or less shall be limited to a maximum of two driveways, unless the director and town engineer determine that more than two driveways are required to accommodate the traffic for the project. Whenever a property has access to more than one street, access shall be generally limited to the lowest volume street where the impact of a new access will be minimized.
2. Single-Family Dwellings and Duplexes. A single-family dwelling or duplex shall be allowed one driveway. A circular driveway may be allowed on a parcel with seventy feet or more of street frontage. A parcel within the RA, RE, or RR zoning districts with a frontage of two hundred feet or more may have two separate driveways, provided that they are separated by a minimum of one hundred feet, or lesser distance as approved by the town engineer based on consideration of site topography and traffic safety.
3. Shared Driveways on Arterials. The use of shared driveways for adjacent parcels located on Barton Road, Brace Road, Horseshoe Bar Road, King Road, Rocklin Road, Sierra College Boulevard, and Taylor Road shall be required where determined by the review authority to be feasible.
B. Distance from Street Corners. Each driveway shall be located a minimum of one hundred fifty feet from the nearest intersection, as measured from the centerline of the driveway to the centerline of the nearest travel lane of the intersecting street. For parcels with frontages less than one hundred fifty feet, the minimum distance shall be one hundred feet unless a lesser distance is approved by the town engineer.
C. Driveway Spacing. Driveways shall be separated along the street frontage as follows:
1. Single-family and Duplex Residential Development. Driveways shall be separated by at least six feet, unless a shared, single driveway is approved by the director. The six-foot separation does not include the transition or wing sections on each side of the driveway; and
2. Multifamily and Nonresidential Development. Where two or more driveways serve the same or adjacent multifamily or nonresidential development, the centerline of the driveways shall be separated by a minimum of fifty feet. Exceptions to this standard shall be subject to the approval of the town engineer.
D. Driveway Width and Length.
1. Single-Family Dwellings. Each single-family dwelling shall be provided a driveway with a minimum length of twenty feet from the back of the sidewalk, or the edge of the right-of-way where there is no sidewalk.
2. Nonresidential Uses. A driveway for a nonresidential use shall have a minimum paved width of thirteen feet for a one-way driveway and twenty-six feet for a two-way driveway. The maximum driveway width shall be thirty feet, exclusive of the area provided for a median divider.
3. Signalized Driveways for Warehouse Retail Uses. A signalized driveway shall have two-way paved access and shall not exceed a maximum paved width of sixty feet.
E. Clearance from Obstruction. The nearest edge of a driveway curb cut shall be at least three feet from the nearest property line, the centerline of a fire hydrant, utility pole, traffic signal, light standards, or other similar facilities. Street trees shall be a minimum of ten feet from the driveway access, measured at the trunk. Driveways shall have an overhead clearance of fourteen feet in height except within a parking structure which may be reduced to seven feet, six inches.
F. Traffic Safety Visibility Area. Structures or landscaping over thirty inches in height shall not be allowed within a traffic safety visibility area. See Section 13.20.050(E).
G. Surfacing. Within the commercial, industrial, RS, RM, and RH zones, driveways shall be paved and permanently maintained with asphalt, concrete, or paving units. Within other zoning districts, the director may authorize the use of other all-weather surfacing, where the director determines that a surface other than asphalt or concrete is consistent with the driveways of similar properties in the vicinity, and that the alternate surface will not impair accessibility for emergency vehicles. A driveway with a slope of fifteen percent or more shall be paved with asphalt or concrete in all cases. (Ord. 290 § 2, 2022; Ord. 285 § 1, 2020; Ord. 205 § 1 (Exh. A), 2003)
