Subchapter III Transportation Management Programs and Construction Management Plans requirements
23.52.010 Transportation Management Program requirements
Transportation management programs (TMP) are a type of transportation demand management strategy that encourages the use of efficient transportation modes rather than single-occupant vehicle (SOV) modes. TMPs aid in managing congestion in transportation networks especially during peak times. Strategies may include, but are not limited to ridesharing, vanpooling, promotion of bicycling, walking and use of public transportation, transportation-efficient parking and land use policies, and high-occupancy vehicle subsidy programs. TMPs are required as indicated in this Section 23.52.010, and applicable rules promulgated by the Director.
A. Non-residential use thresholds for TMPs
1. An applicant who proposes non-residential use development or mixed-use development exceeding the thresholds in Table A for 23.52.010 in zones where a TMP is required, or is otherwise required by code provisions or Director's Rule, shall prepare and include in their Master Use Permit application a TMP.
2. Compliance with TMP requirements does not supplant the responsibility of any employer to comply with Seattle's Commute Trip Reduction (CTR) Ordinance requirements in Chapter 25.02.

An applicant who proposes development with multifamily residential uses exceeding 250 dwelling units in zones where a TMP is required, or is otherwise required by code provisions or Director's Rule, shall prepare and include in their Master Use Permit application a TMP.
C. TMP requirements
1. Non-residential development. For purposes of measuring attainment of SOV-related goals for non-residential development, the proportion of SOV trips shall be calculated for the p.m. hour in which an applicant expects the largest number of vehicle trips to be made by employees, and students if applicable, at the site (the p.m. peak hour of the generator). The proportion of SOV trips shall be calculated by dividing the total number of employees, and students if applicable, using an SOV to make a trip during the expected peak hour by the total number of employee and student person trips during the expected peak hour.
2. Residential development. For purposes of measuring attainment of SOV-related goals for residential development, the proportion of SOV trips shall be calculated for the p.m. hour in which an applicant expects the largest number of vehicle trips to be made by residents of the site (the p.m. peak hour of the generator). The proportion of SOV trips shall be calculated by dividing the total number of residential trips made by SOV during the expected peak hour by the total number of residential person trips.
3. In addition to meeting the requirements in this subsection 23.52.010.C, a TMP shall comply with all applicable rules promulgated by the Director.
4. Building owners shall continue to implement the TMP, submit post-occupancy performance reporting, and conduct enforcement in accordance with any applicable Director's Rules.
