Kimley-Horn will coordinate with the City of Santa Ana on the preparation of cost estimates for the identified improvements. City staff will prepare a planning -level project improvement cost template, including improvement line items and unit costs. Kimley-Horn will review the City's cost estimate form and unit cost assumptions, along with recent available construction cost information, and recommend appropriate methods and unit cost factors to apply in this study. City staff will prepare schematic design drawings of roadway and intersection widening improvements, and will determine quantities and right-of-way implications (full or partial take), and fill out the cost template to develop a cost estimate. For each improvement, Kimley-Horn will determine and document the portion of the total cost that is covered by other committed sources of funding. Committed funding amounts will be subtracted from the total project cost to determine the amount to be included in the fee calculations. We will provide a breakdown of committed funding vs. improvement cost that would be subject to the fee or other funding sources. Task B Deliverables and Meetings • Technical memorandum that reports LOS results, documents forecast congestion, identifies improvements to address congestion, and presents schematic design drawings and cost estimates for identified projects. An electronic version in .pdf format will be submitted on a CD with a printed label. • A meeting with the City staff to review the initial cost estimates form and unit costs. Task C: Develop the Transportation Impact Fee The purpose of this task is to utilize the land use, modeling, and project cost data to calculate the defensible fee level, identify appropriate internal fee area boundaries, and determine a fee level and structure that is reasonable as well as supported by the nexus analysis. Modeling. The first step is to develop model data that will establish the nexus between planned future development and the needed improvements. To keep the fee structure as simple as possible, we will first evaluate the land use and improvement cost data to determine whether a single fee is defensible for the entire City. If the proportion of new trips in each part of the City is in line with the proportion of project costs in that area, a single per -trip cost would be justified throughout the City and there would be no need for separate internal fee areas. We will explore optional approaches for relating trips to costs, relating the total trip generation to total improvement cost by geographic area. The objective of this analysis will be to find a method that establishes a clear connection between trips and improvement costs. The model data will be tailored to the type of nexus being established. if the land use and cost data support a single fee level throughout the City, data that demonstrate trip interactions between different parts of the City will establish the nexus. If the planned development and the needed improvements are dispersed throughout the City, we will use model data to determine each area's trip contributions to each improvement project, and perform a fair share calculation to establish appropriate fee levels. When the modeling is performed to establish the nexus, we will also use the model to determine the sources of existing trips on those roadways, so existing trips can be subtracted and cost allocations are assigned only to future developments.
