2.2.1 New Capacity Costs Detailed cost estimates for each project included in the Transportation SDC Project Plan were reviewed to determine what portion of project costs related to replacement of existing capacity versus expanding existing facilities or constructing new facilities. Existing facility replacement costs included overlay or reconstruction of existing pavement, as well as replacement of existing facilities (e.g., bridges or other crossings). This shows that, in calculating the improvement fee, the City considered the projected costs of the capacity- increasing capital improvements identified on the Transportation SDC Project Plan. 2.2.2 Growth Share of Capacity Costs For purposes of determining SDC-eligibility, individual projects from the Transportation SDC Project List (“Project List”) are analyzed to determine first, the portion of costs that expand or provide new capacity, versus replacing existing system capacity. Second, the new capacity costs are further analyzed to determine the portion of costs related to meeting the needs of future growth (the “growth share”) versus costs associated with raising the level of service for existing development. The general methods used for determining the growth share of costs for each project on the Project List are summarized below. These methods show that, in calculating the improvement fee, the City considered the increased capacity needed to meet the demands of future transportation system users. 2.2.2.1 New Roadways New roadways and expansions driven by future development capacity requirements are allocated 100% to growth, since the capacity is needed entirely for new development. 2.2.2.2 Upgrades to Roadways and Intersections Improvements to existing facilities to address safety, modernization, and other performance considerations provide capacity for growth and enhanced performance for existing development, so the costs are allocated in proportion to the utilization of the facilities. Specifically, weekday PM peak hour travel demand data by roadway link (from the LCOG travel demand model) are used to quantify growth’s utilization of future roadway and intersection capacity. The growth share is estimated based on the growth in trips over the planning period, as a percentage of total future trips for individual roadway links. If a link provides regional ‘through’ traffic capacity, an adjustment to the growth share is made to exclude the portion of trips that represent “through” versus local trips. 2.2.2.3 Operational Improvements Capacity enhancing improvements include new traffic signals, as well as improvements that enhance intersections performance (accessible pedestrian signals and master traffic communications plan). The growth share for these improvements is determined based on growth’s share of future person trips, as estimated from the LCOG travel demand model. November 26, 2018, Meeting - Item 4
