Dowling Associates, Inc. <br />Transportation Engineering Planning Research Education <br />1.3 UPDATE LAND USE ASSUMPTIONS <br />Land Use Inventory <br />The existing land use inventory is the most critical step towards a well validated travel model. Even though <br />we are primarily transportation planners and traffic engineers, Dowling Associates has a great deal of <br />experience with land use inventories and we are currently leading or advising several agencies 011 their land <br />use updates. <br />This scope of work assumes that Pleasanton staff will provide information pertaining to the existing (2009) <br />and future land use data within the City at the detailed TAZ level in a manner consistent with previous land <br />use updates or will direct us to development project reports documenting the assumptions to be incorporated <br />into the land use database. This includes identifying those projects which have been built and occupied in <br />recent years so that their status would change from Approved to Existing, changing recently approved <br />developments from a status of `Buildout' to Approved, etc. <br />Additionally, some information pertaining to occupancy will be provided by the City. If City staff does not <br />have access to these data, field reviews can be performed to estimate occupancy, and tools such as Google <br />Earth can show characteristics such as parking lot occupancy which can be indicators for building occupancy. <br />Review and Update School Zones <br />Dowling will work with City and school district staff to review and update the school zones and enrollment <br />assumptions. All school zones are numbered specifically such that they are identifiable in a group (TAZ <br />240 Previously school enrollment was only forecast for existing plus approved conditions; there wasn't <br />any solid data available for Buildout conditions. In order to account for continued growth in the number of <br />households in the Buildout scenario, Dowling Associates made some assumptions about trends in students per <br />household, in order to match the enrollment targets. <br />Dowling Associates will update the school trip distribution and assignment assumptions to ensure that <br />tracking of school trips is possible and that trip rates make sense from base to future conditions. <br />City of Pleasanton <br />2009 Traffic Model Update <br />City of Me santon Travel Demand Model <br />School boundaries <br />4 <br />May 13, 2009 <br />
