TJKM Transportation Consultants new traffic signals. In addition, there are a few unconstructed carryover projects from the 1998 study. The City is in the final stages of completing its updated Circulation Element which has compiled proposed improvements to streets and intersections using the City's traffic forecast model and the land use from the buildout of the General Plan. When comparing existing deficiencies with buildout deficiencies, the list of improvements required as a result of future growth can be ascertained. In other TIF studies completed by TJKM, we have been successful in including projects that have some degree of current deficiency that is worsened by future development. This is done by ascribing only a percentage of the cost to the degree of development. For example, if a city expects to add 25 percent to its grand total of p.m. peak hour trips between "existing" and "buildout", it may be possible to ascribe 25 percent of the total costs of a particular project to the list of total TDIF project costs. It appears this approach was also utilized in the 1998 study. Pedestrian and Bicycle Imfirovements The City is currently preparing a Pedestrian and Bicycle Master Plan. TJKM expects to be able to draw a list of potential pedestrian and bicycle projects from this plan. Care will need to be taken to select those projects for which a connection, or nexus, can be made to new development. Again, the percentage argument described above may have application here. Several trail projects were included in the 1998 TDIF. Transit Improvements The types of projects that may be included in this category include the capital purchase of transit vehicles, such as paratransit vehicles, ACE station improvements, enhanced bus stops, etc. This list will be developed in conjunction with the staff. - Deliverables: A list of projects to be inducted in the 2008 Pleasanton TDIF. These projects will need to be described in sujjident detail so shot cost estimating, Task 3, can be accomplished. Task 3: Prepare Concept Drawings and Determine Costs of Projects In this task, engineers with Mark Thomas Company will prepare conceptual plans for each TIF project delineating the limits of proposed improvements including street widenings, intersection improvements, new alignments and pedestrian and trail improvements. Construction costs of the projects indentified in Task 2 will be estimated. Mark Thomas will work with the City in establishing appropriate cost estimating procedures including unit costs and items appropriate to include in the TDIF. Each project will have one or more I Ixl7 sheets of concept drawings included. A sample drawing prepared by Mark Thomas Company for the recent Livermore TIF project is shown on the following page. Detailed quantities and unit costs will be developed to establish construction costs and support costs for each project. Template forms for the quantities and cost estimates will be prepared so that future updates could be more easily prepared. - Deliverables: A conceptual drawing of each improvement including at least one I 1 x 17 sheet The cost of each project to be included in the TDIF will be iden~ed.
