Ordinance 3387-14 - Laserfiche WebLink

5. For any project, the City Traffic Engineer may make a case-by-case determination of the horizon year, including extension of the horizon year, or the requirement for intermediate analysis years, for projects that are built in phases or designed to be built over a number of years. 7.3 Base traffic and growth factor. The base traffic for the traffic analysis shall include existing traffic plus traffic generated by any project in the study area that has been previously reviewed under SEPA, any proposed project currently under review by the city, and any additional traffic reasonably foreseeable as deemed appropriate by the City Traffic Engineer. This additional traffic may include trips generated in other jurisdictions. The applicant may request to use a specific growth factor if the applicant can demonstrate with analysis that such a growth factor is appropriate for the project location and is not inconsistent with the comprehensive plan (including SEPA or other traffic analysis supporting the comprehensive plan). The City Traffic Engineer may require that a different background growth factor be used when site specific information supports a different factor. Where there is no area specific information, a four (4) percent background growth factor compounded annually shall be used to project the existing traffic to the required horizon year. 7.4 Trip generation and distribution. The traffic analysis shall assign and distribute the proposed project's peak hour trips down to and including the minimum threshold level of 50 new project-generated peak hour trips. Unless otherwise required or approved by the City Traffic Engineer, trip generation rates shall conform to the latest edition of Institute of Transportation Engineers (ITE) Trip Generation Manual. Where proposed traffic or transportation impacts are not predominantly automobile (for example, trucks, trailers, rail, air or waterborne traffic), the analysis shall identify the type of traffic and mode split in the generation and distribution analysis. Directional distribution shall be determined in consultation with the City Traffic Engineer. For large projects or in areas experiencing substantial development activity, the City Traffic Engineer may require directional distribution and trip assignment to be performed using computerized model. 7.5 Level of service. The method for analyzing the Level of Service when required (see section 9 of this ordinance) shall be the current edition of the Transportation Research Board Highway Capacity Manual and its related computer software, or a method otherwise approved by the City Traffic Engineer. 7.6 Other items. The traffic analysis shall include applicable items in sections of Exhibit 1, as well as other items relevant to the particular project being reviewed, as determined by the City Traffic Engineer. Section 8: Mitigation analysis and plan The traffic analysis shall identify and/or include the following elements with respect to transportation improvements to mitigate the project's likely transportation impacts: improvements required to maintain level of service standards, local frontage improvements, proportionate share for planned improvements as identified in this ordinance, and any other elements required by the City Traffic Engineer to adequately mitigate traffic impacts from the project. -4-
