Home My WebLink About05-28-86 Meeting of the La Porte Area Water Authority Minutes (approved 8-12-86) LA PORTE AREA WATER AUTHORITY BOARD MINUTES MAY 28, 1986 1. The meeting was called to order at 7:00 P.M. by President Jerry Bramlett. MEMBERS PRESENT: President Jerry Bramlett, Vice President Al Fields, Member Cary Burnley MEMBERS ABSENT: Secretary Rick Matthews OTHERS PRESENT: City Manager Jack Owen, Authority Attorney John Armstrong, Acting Public Works Director Steve Gillett, Director of Community Development John Joerns, Cecil Allen of Turner, Collie & Braden, Inc., Michael S. Marcotte, Assistant to the Director of Public Works, City of Houston. 2. The minutes of the meeting on May 28, 1986, were read and approved. 3. Micha~l Marcotte made a presentation on the City of Houston's proposed Southeast Water Treatment Plant. He reported that the bonds had been sold but to date only Webster had signed a contract to receive water from them. The plant was bid last month at approximately $72 million, plus land and engineering. Mr. Marcotte stated that should the La Porte Area Water Authority sign a contract with the City of Houston for a guaranteed amount, no other part of the system would reduce that amount. Also, it would not be a take or pay contract, only the water used would be billed plus the capital portion. The next expansion would begin in approximatley 5 years and any entity with a contract would have the right of first refusal on any expansion. He suggested that the Authority put together a proposal showing quantity required, any increase forecast, and how it would be paid. Turner, Collie & Braden, Inc. had given Mr. Marcotte a list of questions that he answered at this meeting. Cecil Allen of Turner, Collie & Braden, Inc. is to get a written response to these questions. Also, Mr. Allen is to get a copy of the bond schedule for the Southeast Plant. Jack Owen will contact Ron Neighbors of the Harris-Galveston Counties Coastal Subsidence District to attend the next meeting of the Authority to address the changes to the planned conversion that was submitted in February, 1986. 4. There being no further business, the meeting was adjourned at 9:00 P.M.

ADJOURNMENT I I LA PORTE AREA WATER AUTHORITY BOARD MINUTES MAY 28, 1986 1. The meeting was called to order at 7:00 P.M. by President Jerry Bramlett. MEMBERS PRESENT: President Jerry Bramlett, Vice President Al Fields, Member Cary Burnley MEMBERS ABSENT: Secretary Rick Matthews OTHERS PRESENT: City Manager Jack Owen, Authority Attorney John Armstrong, Acting Public Works Director Steve Gillett, Director of Community Development John Joerns, Cecil Allen of Turner, Collie & Braden, Inc., Michael S. Marcotte, Assistant to the Director of Public Works, City of Houston. 2. The minutes of the meeting on May 28, 1986, were read and approved. 3. Michael Marcotte made a presentation on the City of Houston's Southesast Water Treatment Plant. He reported that the bonds had been sold but to date only Webster had signed a contract to receive water from them. The plant was bid last month at approximately $72 million, plus land and engineering. Mr. Marcotte stated that should the La Porte Area Water Authority sign a contract with the City of Houston for a guaranteed amount, no other part of the system would reduce that amount. Also, it would not be a take or pay contract, only the water used would be billed plus the capital portion. The next expansion would begin in approximatley 5 years and any entity with a contract would have the right of first refusal on any expansion. He suggested that the Authority put together a proposal showing quantity required, any increase forecast, and how it would be paid. Turner, Collie & Braden, Inc. had given Mr. Marcotte a list of questions that he answered at this meeting. Cecil Allen of Turner, Collie & Braden, Inc. is to get a written response to these questions. Also, Mr. Allen is to get a copy of the bond schedule for the Southeast Plant. Jack Owen will contact Ron Neighbors of the Harris-Galveston Counties Coastal Subsidence District to attend the next meeting of the Authority to address the changes to the planned conversion that was submitted in February, 1986. 4. There being no further business, the-meeting was adjourned at 9:00 A.M.
