(Added by Ordinance No. 177028; amended by Ordinance No. 182760, effective June 5, 2009.) The purpose of this chapter is to describe the requirements for a transportation impact study, to ensure an adequate level of street connections to serve land uses, and to ensure that improvements to these streets are made in conjunction with development consistent with fire, life safety, and access needs.
(Replaced by Ordinance No. 177028; amended by Ordinance No. 187681, effective May 13, 2016.) As used in this Chapter, the following terms shall have the following definitions:
A. "Exceptional Habitat Quality" for connectivity purposes:
1. Riparian-associated wetlands protected with environmental zones;
2. Locally or regionally rare or sensitive plant communities;
3. Important forest stands contributing multiple functions and values to the adjacent water feature habitats of sensitive, threatened or endangered wildlife species; or
4. Habitats that provide unusually important wildlife functions, such as (but not limited to) a major wildlife crossing/runway or a key migratory pathway.
B. "Mixed-Use Area" is compact development that allows a mix of uses, either within buildings or among buildings, and includes residential development as one of the potential components. Mixed-use areas include all commercial zones (CN1 and 2, CO1 and 2, CM, CS, CG, and CX), the EX, Central Employment Zone, and the IR, Institutional Residential Zone, All other employment zones, industrial zones, and the Open Space Zone are not included.
C. "Significant alterations" are changes to property that are 35 percent or greater than the assessed value of all improvements on the site. Mandatory improvements for fire, life safety and accessibility do not count toward the threshold.
D. “Single-family residential zone” means any of the Single-Dwelling Zones identified in Title 33 of the City Code.
E. “Frontage” means the length of public right-of-way adjacent to a property, measured in feet, but does not apply to collectors, arterials, or alleyways.
F. “Unimproved street” means any local street without a curb other than a local street that has been formally accepted by the Bureau of Transportation as having been fully built to an adopted Residential Shared or Residential Separated City street standard that does not require a curb.
G. “Local street” means any street classified as a Local Service Street in the City’s adopted Transportation System Plan.
H. “Subdivision” means a division of land into four or more lots.
I. “Local Transportation Infrastructure Charge” is a charge collected to fund improvements to the City’s network of unimproved local streets and adjacent or related transportation facilities.
(Replaced by Ordinance No. 177028; amended by Ordinance Nos. 182760, 184957 and 187681, effective May 13, 2016.) All building permits and planning actions are subject to the following:
A. No single family, multiple dwelling, industrial or commercial building shall be constructed, or altered so as to increase its number of occupants, or make significant alterations to a building without resulting in increased occupancy, on property that does not have direct access by frontage or recorded easement with not less than 10 feet width of right‑of‑way to a street used for vehicular traffic.
B. If a street adjacent to a property described in Subsection A. above does not have a standard full-width improvement, including sidewalks, the owner, as a condition of obtaining a building permit, conditional use, zone change, land partition or adjustment, shall provide for such an improvement or a portion thereof as designated by the Director of the Bureau of Transportation in accordance with provisions elsewhere in this Title. The payment of a Local Transportation Infrastructure Charge will satisfy the requirements of this Subsection.
C. Based on findings that a standard improvement is not feasible, the Director of the Bureau of Transportation may allow a temporary improvement appropriate for the circumstances, on the condition that the City will not maintain said temporary improvement and the owner will provide the City with a notarized document, approved as to form by the City Attorney, to be filed with the County in which property is located, stating that the present and future owners will be counted in favor of any proposed standard improvement of said street. Fee for said filing and any other expense of the City incidental to accomplishing the temporary improvement shall be paid by the owner.
(Replaced by Ordinance No. 177028; amended by Ordinance No. 182760, effective June 5, 2009.) Unless permitted as part of an approved Planned Development the Council permits by ordinance, no multiple dwellings or accessory building shall be so located on any lot, block, tract or area within the City that any portion of the dwelling or building will be more than 250 feet from a dedicated street abutting the lot or block or that portion of a tract or area on which the multiple dwelling or accessory building shall have direct access to such street by way of an approved roadway.
(Replaced by Ordinance No. 177028; amended by Ordinance No. 184957, effective November 25, 2011.) Street connectivity provides access to adjacent properties and reduces out-of-direction travel. New or expanding development must include the following:
A. Through streets as required by the Director of the Bureau of Transportation connecting existing dedicated streets, or at such locations as designated by the Director of the Bureau of Transportation, shall be provided for any development or redevelopment.
B. Partial-width streets as required by the Director of the Bureau of Transportation where full-width streets could reasonably be provided in the future with the development or redevelopment of abutting property.
C. New residential development or development in existing or future mixed-use areas that will require construction of new street(s) must:
1. Respond to and expand on the adopted street plans, applicable to the site or area, or in the absence of such plan, as directed by the Director of the Bureau of Transportation;
2. Provide for street connections no further apart than 530 feet, except where prevented by barriers such as topography, railroads, freeways, pre-existing development, or natural features where regulations do not allow construction of or prescribe different standards for streets;
3. Provide bicycle and/or pedestrian connections when full street connections are not possible, no further apart than 330 feet except where prevented by barriers as noted above;
4. Limit the use of cul-de-sac or closed street systems; and
5. Include street cross section(s), as directed by the Director of the Bureau of Transportation.
D. Street and pedestrian/bicycle spacing standards may be modified in areas of exceptional habitat quality to the following standards:
1. Where streets must cross over protected water features, provide crossings at an average spacing of 800 to 1,200 feet, unless exceptional habitat quality or length of crossing prevents a full street connection.
2. Pedestrian and bicycle connections that cross protected water features should have an average spacing of no more than 530 feet, unless exceptional habitat quality or length of crossing prevents a connection.
(Replaced by Ordinance No. 177028, effective December 14, 2002.) The traffic impacts of dividing or developing land may warrant a transportation impact study. The purpose of a transportation impact study is to assess the effects of development in the vicinity of a site on traffic conditions and operations; transit, pedestrians, and bicycle movement; and neighborhood livability. A transportation impact study may be required under the following situations:
A. Where approval criteria for a land use review include a requirement of adequacy of transportation services and the development proposed through the review meets or exceeds the following thresholds:
1. Trip generation threshold. More than 100 new vehicle trips will be generated in the peak direction (inbound or outbound) during the site's peak traffic hour; or
2. Neighborhood traffic threshold. More than 250 new trips will be generated per day that are likely to use predominately residential Local Service Traffic Streets.
B. Safety or operational impacts. Where the City Engineer has identified potential safety or operational concerns that may be impacted by the layout of a site or the location or size of driveways for a proposed development.
(Added by Ordinance No. 177028; amended by Ordinance No. 182760, effective June 5, 2009.) No permit shall be issued for the construction of any dwellings or buildings upon any lot, block, tract or area within the City until required dedications, as outlined in this Chapter, are complete.
(Added by Ordinance No. 177028; amended by Ordinance No. 182760, effective June 5, 2009.) The Bureau of Transportation, may, upon the request of the Commissioner In Charge of the Bureau of Parks and Recreation, take over and perform the construction, reconstruction, maintenance and repair of any boulevards, roadways, drives, paths, trails, walks or other routes of travel in park areas of the City. The transfer of such responsibility to the Bureau of Transportation shall not operate to remove the routes of travel from the jurisdiction and control of the Bureau of Parks and Recreation, and the planning and location of new routes shall remain the responsibility of, and in the jurisdiction of the Bureau of Parks and Recreation.
(Added by Ordinance No. 178424; amended by Ordinance No. 182760, effective June 5, 2009.) East Corridor Plan District. Until a master street plan is adopted in the Transportation Element of the Comprehensive Plan for the East Corridor Plan District, as shown in Title 33, Map 526-1, street connectivity for the area should generally be based on a block size of 400 by 200 feet and connect to the surrounding street grid consistent with the prevailing block pattern.
(Added by Ordinance No. 187681, effective May 13, 2016.)
A. An applicant for a new, single-family, residential, building permit for a project of one or two units or for approval to create multiple lots other than as part of a subdivision on real property within a single-family residential zone must pay a Local Transportation Infrastructure Charge.
B. The Bureau of Transportation will assess a Local Transportation Infrastructure Charge according to the total number of linear feet of unimproved street frontage. The charge will be based on the average, location-specific, actual cost to the City to build local street improvements to City standards at the time of application.
