Richards, Director of Community Development DATE: July 6, 1990 (CC meeting 7-25-90) SUBJECT: DP 290 MINOR MODIFICATION NO. 3 (LITTON) Background On June 27, 1983 DP 290, a 134,000 square foot industrial building was approved by the County of Ventura. The building has been occupied by Litton Aero Products since its completion. Discussion The requested Minor Modification to DP 290 is to allow construction of a wooden storage shed on the roof of the building. The proposed shed is fourteen feet in length, ten feet in width and eight feet in height. This shed will be located behind an existing roof screen five feet in height and will be painted to match the building and be used to house a laser radar used for atmospheric testing (please see the enclosed letter for a more detailed description). The shed will be removed after the six month testing period is completed. The roof of the shed will extend for three feet above the height of the roof screen. The existing elevator shaft already extends above the level of the roof screen by five feet (see attached photographs). The roof screen and elevator shaft is located at the approximate center of the building and is not visible from the street 799 Moorpark Avenue Moorpark, California 93021 (805) 529-6864 below. The Director of Community Development will condition that the shed be painted to match the building and roof screen and that it will be removed after six months have passed. The Director of Community Development has reviewed the proposed modification and intends to approve it. Pursuant to Resolution No. 86-523 the Director has the authority to approve Minor Modifications. This matter is being presented to the Council as a courtesy. In the event the Council wishes to appeal the Director's decision, it may do so. Should the Council desire to appeal, it should set a public hearing date. the next available meeting date would be the Council's regular meeting of August 15, 1990. If the Council takes no action then the Director's decision stands. Recommendation Receive and file.

EXHIBIT Litton 6101 Condor Dnve Aero Products Moorpark.California 93021.2699 805 378.2000 June 29, 1990 Mr. Paul Porter Senior Planner City of Moorpark 799 Moorpark Ave. Moorpark, CA 93021 Dear Mr. Porter: APD has identified the potential of State-of-Art laser radar technology for development of a new product capable of predicting winshear detection. Windshear is one of the leading causes of avionic accidents, responsible for several hundred fatalities over the past two decades. Windshear, which is a form of rapid change in air speed and direction in an unstable atmospheric condition, poses a significant threat to aircraft during takeoff and landing. The laser radar work at APD is directed toward the development of a sensor which can predict windshear ahead of time. This would allow the pilot to take appropriate action to avoid any incident and eliminate the possibility of a crash. Such a predictive sensor can greatly improve the commercial avionic safety and save hundreds of lives over the years to come. A breadboard laser radar is currently being assembled at APD to perform various measurements in the atmosphere. Further progress in our effort relies on these measurements. It is planned, subject to your approval, to perform the atmospheric measurements from the top of our facility by installing a wooden shed on top of our facility for a period of only six months, beginning in July of 1990 and ending in January of 1991. The shed shall be painted to match the color of the facility. Placed inside an existing parapet, the shed will protrude three feet above the parapet. Due to the location of the parapet on top of the facility, the shed will not be visible from any direction. Naturally, all of the safety factors, particularly when related to the laser beam, have been considered in detail. The transmitted laser beam complies with the safety requirements as documented in the "American National Standards for the Safe Use of Lasers" (ANSI Z136. 1-1986) . The laser radar system uses a Holmium Solid State Laser as a source.
