17.04.010 Transportation mitigation requirements.
All development activities in the city are subject to the following requirements:
A. Traffic Impact Analysis (TIA) Required. In order to provide sufficient information to assess a development’s impact on the roadway system, any development activity adding 10 or more vehicle trips to a corridor during the peak hour shall be required to provide a traffic impact analysis. The traffic impact analysis requirements are defined in the Bothell Standards. In addition, the director may require new development to evaluate any potential traffic and parking impacts on neighborhood or local access streets. The director is authorized to adopt administrative policies and technical procedures specifying the contents and scope of the TIA, the methodologies to be used in preparing a TIA, and the nature and extent of the improvement(s) necessary to meet the requirements of this chapter.
B. Level-of-Service Policy. The city shall maintain or achieve LOS E (typically based on the highest p.m. peak hour) on the following corridors:
1. SR-524 (SE 208th St./Maltby Road) Corridor between 9th Ave. SE and 39th Ave. SE;
2. SW 228th St./SE Corridor between 4th Ave. W and 39th Ave. SE;
3. SR-522 (NE Bothell Way) Corridor between 96th Ave. NE and Kaysner Way;
4. Beardslee Boulevard/NE 195th St. Corridor between NE 185th St. and 120th Ave. NE;
5. SR-527 Corridor between SR-524 and SR-522;
6. 39th/35th Ave. SE/120th Ave. NE/180th St. Corridor between SR-524 and 132nd Ave. NE;
7. NE 145th St./Juanita-Woodinville Way/NE 160th St. between 100th and 124th Ave. NE.
C. Development Mitigation Obligations. Frontage improvements will be required of all proposed developments, pursuant to Chapter 17.09 BMC.
The director shall require mitigation of direct traffic impacts of any development as specified below. Mitigation of off-site impacts to city streets will be in the form of transportation impact fees pursuant to Chapter 17.045 BMC. Mitigation of site-specific impacts to the city’s transportation system may be required under the State Environmental Policy Act (SEPA). SEPA mitigation may be required on arterial streets, neighborhood or local access streets. Mitigation of off-site impacts to state highways or other jurisdiction streets may also be required, as specified in this chapter. Development may have the option to provide mitigation directly by constructing the improvements that offset the direct traffic impact of the development. Development mitigation requirements may be reduced by the director if the development implements transportation demand management and/or transportation system management strategies.
D. Inadequate Road Condition(s).
1. A development’s access onto a public road shall be designed so as not to create or aggravate an inadequate road condition. Developments shall be designed so that inadequate road conditions are not created.
2. Mitigation of direct project impacts resulting in inadequate road conditions is required. If such conditions are found to be existing in the development’s road system at the time of development application review, and the development shall put 10 or more peak hour trips through the identified locations, at the time of full occupancy of the development, the development shall only be approved if provisions are made in accordance with this chapter for improving the inadequate road conditions. (Ord. 2014 § 1 (Exh. A), 2009; Ord. 1946 § 4, 2005; Ord. 1881 § 2, 2002; Ord. 1654 § 3, 1996; Ord. 1633 § 1, 1996).
