Where a dead-end road crosses areas of differing zoned parcel sizes, requiring different length limits, the shortest allowable length shall apply. Note 2 – Documentation of grade taking into account subsequent surfacing to be installed shall be provided by an appropriately licensed professional prior to application of base material when the road is over 7% and unpaved, and when over 12% when paved. The County Engineer may require grade documentation in other cases, regardless of intended slope. Note 3 – All one-way roads shall connect to a two-lane road at both ends and may provide access to an area in which the General Plan would allow no more than 10 dwelling units. Maximum length of one-way roads is 2640 feet. Note 4 – Turnarounds are required at the terminus of all dead end roads or lanes and shall be provided at a maximum of 1320 foot intervals, not including the intersection. A turnaround shall be provided at all building sites on driveways over 300 feet in length and shall be within 50 feet of the building. Where a one way single lane traffic lane provides access to a gated entrance, a turnaround is required before the gate. Note 5 - A lane may have two entrances when served by a private road not offered for dedication or accepted for maintenance by the County. Note 6 - Designs that vary from the typical drawings shown on R-13 and R-14 may be approved provided they can be shown to allow the maximum size fire equipment that serves the area to turnaround with no more than 3 maneuvers. ---PAGE BREAK--- Page 14 of 15 Note 7 - Must meet SRA Fire Safe Regulations. Design by a qualified professional may be required by the Director of Public Works or the Chief Building Official. Note 8 - Driveway grade for atypical encroachments for 30 feet beyond EOP shall be the same as driveway grade within the ROW. Recommendation is from EOP within ROW for downhill driveway staging, and for 8 feet from EOP for uphill driveways to allow for proper drainage routing to the roadside ditch and vehicle staging. Documentation of grade taking into account subsequent surfacing to be installed shall be provided by an appropriately licensed professional prior to application of base rock when over 7% and unpaved, and when over 12% and paved. The Director of Public Works and/ or the Building Official may require grade documentation in other cases, regardless of intended slope. Kirkwood specific plan requires that vehicular access centerline slope for a distance of 20’ from the Right of Way line may not exceed 10% when serving 4 or fewer dwellings, or 8% when serving 5 or more dwellings. Note 9 - Alternative designs for ditch crossings (Standard Drawing R-7) will be considered on a case by case basis, including use of arch pipes, if pipe sizes proposed are determined to be of capacity equivalent to those shown; alternative bedding or cover techniques; and when crossings are over atypical ditches. Note 10 – All driveway, road, street, and private lane roadway structures ( including bridges) shall be constructed to carry at least the maximum load and provide the minimum vertical clearance as required by Vehicle Code Sections 35550, 35750 and 35250, or these standards, whichever are more stringent. Appropriate signing, including but not limited to weight or vertical clearance limitations, one- way road or single lane conditions, shall reflect the capability of each bridge. A bridge with only one traffic lane may be authorized; however, it shall provide for unobstructed visibility from one end to the other and turnouts at both ends. Development permit applications that include a bridge shall include appropriate engineering calculations, and documentation of permits or approvals from all other appropriate agencies. Note 11 - An 18’ travel way width may be permitted where deed restrictions limit the construction on two parcels served to 1 Group R, Div. 3 Occupancy/ parcel. This arrangement is typical of a duplex. Note 12 – ---PAGE BREAK--- Page 15 of 15 Kirkwood specific plan requires that driveways providing access to garages or parking areas that are set back more than 20 feet from the property line shall have a maximum width of 14 feet at the property line; driveways providing access to garages and parking areas that are set back 20 feet or less from the street right of way shall not exceed the width of the garage door opening plus 2 feet at the property line. Kirkwood Specific Plan allows a maximum grade of 8% for not less than 20 feet from the right- of-way of a street. Kirkwood Specific Plan sets a minimum width of 24 feet for two way facilities and a maximum width of 30 feet. Note 13 - When driveway encroaches on paved road, the driveway shall be paved from the edge of road pavement to edge of Right of Way. Note 14 - Where two or more driveways serve the same parcel, the centerlines of the driveways shall be separated a minimum of 50 feet. ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK---
