Proposed School Site - Pajaro Valley Unified School District, Santa Cruz County

In response to your request of December 19, 1991 and Section 39006 of the Education Code, the California Department of Transportation, Division of Aeronautics, has analyzed eleven school sites proposed by the Pajaro Valley Unified School District. The proposed sites are located at various locations around the Watsonville Municipal Airport, see attached map. Click to view.

Our analysis consisted of a thorough review of our files concerning the Watsonville Municipal Airport, including layout plans and vicinity maps depicting the relationship of the airport traffic patterns to the proposed sites. In addition, a fly over was conducted to further evaluate the sites. The Airport Manager, Ms. Kim Wirht, was offered the opportunity to respond. Her comments were considered. Our evaluation revealed that Sites #1, 7, 9, 10 and 11 List of sites, were undesirable sites because they are under the flight tracks of aircraft performing critical flight maneuver at low altitudes for approaches and departures into and out of the Watsonville Municipal Airport.

We have some reservations regarding Site #2, 3, 4 and 6 because of some safety and noise concerns. We recommend that the school district explore all alternative sites before selecting any of these sites. If Site #2, 3, 4 or 6 is selected, we recommend that mitigation be taken to minimize outside noise impacts to within 45 decibels inside the classroom.

We have only some noise concerns for Site #8 and recommend the same noise mitigation procedures be taken as described above. We have no safety or noise concern for Site #5. Page 2 The Department cannot guarantee the safety of any of the sites above. However, based upon our evaluation of existing conditions and planed development, Site #2, 3, 4, 5, 6 and 8 are considered to provide the level of safety suitable for a school. We, therefore, do not object to the acquisition of these proposed school sites. However, if a site is not acquired by January 31, 1997 another site evaluation will be required.
