H\DEVELOPMENT\Design Standards\Chapter 10 (01-10) Alleys serving alley loaded lots shall include provisions for unimpeded vehicular circulation along the alley, and provisions for adequate sight distances along both the alley at driveways and at intersections with public streets. 10.01.5 Private Access Roads on Access Tracts or Easements (Shared Driveways) Access roads provided on access tracts or easements, also known as shared driveways, provide access for up to six (6) residential units on panhandle/flag lots and rear lots that do not have direct access to public street frontage. They will be private roads that shall be maintained by the property owners who use them to access their property. All access roads shall meet the following general standards: 1. Access roads shall be limited to six hundred feet (600’) in length. 2. The width of the access tract/easement shall match the required pavement width, including the width of any pedestrian improvements, and the area needed for private drainage facilities. If the access is also acting as a joint utility easement or tract, the width must accommodate the public utility requirements. 3. The connection of an access road to the public street shall be by a commercial driveway apron. The connection of individual lots to the access road shall be by either a residential or commercial driveway apron commensurate with the use of the property. 4. Access roads shall meet the geometric design standards for local residential streets. 5. Access roads shall be signed as private drives inclusive of all addresses being served off the access road. New and/or existing access roads serving two (2) residential units shall meet the following additional standards: 6. The minimum pavement width shall be twenty-four feet (24’). The pavement width may be reduces to twenty feet (20’) if the new residential unit using the access road has a residential fire sprinkler system installed or a fire hydrant exists within four hundred and fifty feet (450’) of the residences measured as the fire vehicle lays its hose. Existing access roads serving three (3) or more residential units when only one additional residential unit is being created or developed shall meet the following additional standards: 7. The minimum pavement width shall be twenty-four feet (24’) and be marked as a fire lane per ACC 15.36A. The pavement width may be reduced to twenty feet (20’) if the new residential unit using the access road has a residential fire sprinkler system installed or a fire hydrant exists within four hundred and fifty feet (450’) of the residences measured as the fire vehicle lays its hose. 8. An additional five foot (5’) wide pedestrian pathway along one side of the paved access road separated by a four-inch (4”) wide painted line. 9. Access roads exceeding one hundred and fifty feet (150’) in length shall also include an adequate turnaround at the end of the road. 12/21/2009 ........................................... Design Standards ............................................ Page 10-6 REF. H\DEVELOPMENT\Design Standards\Chapter 10 (01-10) New access roads serving three (3) to six (6) residential units shall meet the following additional standards: 10. Access roads seventy-five feet (75’) or less in length shall have a minimum pavement width of twenty feet (20’) and shall be marked as a fire lane per ACC 15.36A. 11. Access roads exceeding seventy-five feet (75’) in length shall have a minimum pavement width of thirty-four feet (34’). The pavement width may be reduced to twenty-four feet (24’) if one side of the access road is marked as a fire lane per ACC 15.36A. 12. Access roads exceeding one hundred and fifty feet (150’) in length shall also include an adequate turnaround at the end of the road. 13. An additional five foot (5’) wide sidewalk and cement concrete traffic curb per F-10.12-00 is required on both sides of the access road. The material for the sidewalk shall be consistent with the surrounding neighborhood sidewalk. New access roads serving non-residential properties shall meet the following additional standards: 14. The minimum pavement width shall be twenty-four feet (24’) for access roads servicing commercial properties and thirty feet (30’) for access roads serving industrial properties. 15. The access road will be marking as a fire lane per ACC 15.36A. 16. Access roads exceeding one hundred and fifty feet (150’) in length shall also include an adequate turnaround at the end of the road. 10.01.6 Half-Streets A Half-Street could be comprised of any one of the above mentioned street classifications. Half-Streets require, at a minimum, the construction from one side of the street, including the curb and gutter, storm drainage, sidewalk, lighting, conduits, and landscape strip, to the street centerline. Half-Streets will need to be constructed when a proposed new development or redevelopment of a property is located on a public street that is not currently built to City standards. Half-Street construction may also be required for property that abuts future streets proposed in the City’s Comprehensive Plan. When Half-Street construction is required on an existing paved street, the design of the Half-Street shall be consistent with the existing street conditions. This could require construction of more than half the street for safety and drainage reasons. When Half-Street construction is required on unpaved streets or unimproved areas, a minimum of twenty-four feet (24’) of pavement will be required. In these cases, the street should be designed to provide drainage for the constructed portion of the street. Provisions shall be made to allow for extension of the storm drainage system to the undeveloped portion of the street for future construction. The construction of a Half-Street may require the dedication of additional right-of-way. If a Half-Street does not connect at both ends to other streets, construction of a cul-de-sac will be required. Where Half-Streets are connected to existing streets, transition tapers will be required when edges of pavement do not match. The following formula provides the information necessary to determine the length of the tapers for a specific situation: For street design speeds of less than forty miles per hour (40mph)
