SR 89:133 Page 7 Short Range Analysis There are a number of variables involved in the Short Range Analysis. These are: When will the buildings really be built? How long will it take for them to fill up? How long will it take to construct funded transportation improvements? Current short range analysis assumes that all buildings will fill to 100% and that all under construction transportation mitigation improvements which are included in the trip assignment model will be completed and in place at the time the buildings reach occupancy, and that a level of service of "E" is NOT acceptable (v/c>=0.91). The short range analysis includes in the transportation system all components of existing streets and also all components from those projects under construction (eg. 1-680 Stoneridge interchange). It also includes all North Pleasanton approved private development projects at 100% occupancy and all constructed buildings factored to 100% occupancy. The model does not have the 1-580 Hacienda or Santa Rita interchange improvements included, as these are not yet "under construction." Staff has been requested by the NPID Committee to reduce the percent occupancy from the current 100% used in the trip generation model. The argument to reduce the occupancy rate is that it is unreasonable to expect all multi-tenant buildings to fill to 100% at the same time and that, even within a single building, it is not likely that all spaces will be used to maximum occupancy. The NPID Committee has submitted data to support this request. (Attached) The information compiled in this year's occupancy studies showed the average occupancy of the 16 buildings included within the Driveway Study to be 87%. The average occupancy of all buildings considered in the "Office" category was 83%. Most "Owner- Occupied" buildings are shown as 100% occupied while the vacancy rate occurs in "Multi-Tenant" buildings. Where there are a number of unknowns, the more common practice in traffic engineering is to use the full (100%) occupancy figure. Where more information is available, it is possible to predict based upon that information. In a short term projection, it is unlikely that all buildings will reach 100% occupancy and a more probable percentage of 90 to 95% could be used. This would assume that additional buildings (and additional traffic improvements) can continue to be built, avoiding a saturated market and allowing mitigation to keep abreast of occupancy.
