    Legal Analysis of King County’s Role in Des Moines Beach Park Conveyor Belt Proposal

    FM: James L. Brewer, Legal Counsel ("{i;f" RE: Des Moines Beach Park Kimberly Lockard has asked me to give you a written analysis of the County's role and jurisdiction on the issue of the proposed operation in Des Moines Beach Park of a fill material conveyor belt. I would like to thank Scott Johnson, Deputy Prosecuting Attorney, for his assistance to me in responding to your request. King County owns a real property interest in one section of the Des Moines Beach Park. The deed conveying that portion of the park from the County to Des Moines has a covenant granting: "King County and its people for their benefit the right to use the real property herein for public park and recreation purposes in perpetuity." If that portion of the park is ever used for other purposes without the written consent of King County, ownership of the park property reverts to King County. In addition, Des Moines is under a contractual obligation to King County to only use the park for "park and recreation" purposes unless King County consents to the inconsistent use and other land is substituted. This obligation applies to the entire park. It is likely these covenants were included, in part, because King County's contribution to the purchase of the park came from Forward Thrust bond proceecis. The Office of the Prosecuting Attorney has indicated that it is their understanding that Des Moines Creek Park also was purchased by King County with Forward Thrust bond proceeds. The…

    C.A.S.E. MEETING MINUTES May 1, 2002

    +Senator Karen Keiser: new 33rd District Senator 7:05pm - A State Senate Transportation Committee hearing will be held on July 18th. On the agenda is consideration of the need for a second regional airport. This is the first step of many to get the legislature to approve the study and proceed to site a new airport. Meeting to be held in neutral Wenatchee. + Welcome comments by CASE President Brett Fish 7:10 pm In the News: The Port is shooting Canadian Geese across from Sunnydale grade school. The Port does the FAA requirement & the Fish & Wildlife permits to keep birds away from the airport. Brett contacted KOMO & KING TV and South and East County Journal picked it up along with Tacoma News Tribune ... all talking abut the geese. Brett then showed a recording of the KOMO TV New article questioning the use of firearms around homes, business and schools. The Port needs to disperse information to the schools before shooting. The Highline Times ran an advertisement "10 Reasons for a Conveyor Belt". The Westcot Co. must be desperate to be running these ads. They are also running TV adds on CNN, History Channel, Cable News & Fox. For all of this media advertising blitz, as of this date, only 2 favorable e-mail responses to the Des Moines City Hall for the conveyor and close to 100 negative against. .. Westcot's media campaign is falling way short of their goal to get the Des Moines City Council…
