CALL TO ORDER ROLL CALL OF COUNCIL MEMBERS DISCUSSION Storm drainage problem Andover Park West and So. 180th Street AUDIENCE COMMENTS RECESS TUKWILA CITY COUNCIL 6� SPECIAL MEETING Tukwila City Hall Council Chambers MINUTES Mayor Todd called the Special Meeting of the Council to order. GARDNER, STERLING, TRAYNOR, DAVIS, HARRIS, SAUL, JOHANSON. It was noted that due to illness the City Clerk was not present so Maxine Anderson would record the Minutes of the meeting. Jim Waite, Highline Times, announced the meeting was properly advertised in their newspaper. Mayor Todd stated that the subject to be discussed is the Andover Park West and South 180th Street Storm Drainage Problem. The meet- ing was turned over to Steve Hall, Public Works Director, who des- cribed the boundaries of the P -17 drainage area and the problems in- volved with allowing further development of this area. At the pre- sent time, the natural drainage is into an existing creek which flows North ending in a ponding area on the Doce's site. When the pond overflows, a portion of the runoff goes into the existing 18" culvert on Southcenter Parkway and the remainder flows into a 30" culvert on the South access road of the McCann Development which overflows into the 60" pipe on Andover Park West. The Comprehensive Plan calls for a 54" culvert from a point where the creek enters the Doce's site easterly to Andover Park West where it will tie into the existing 60" storm drain. The problem is: at what point in time will the existing 60" storm drain line in Andover Park West reach its capa- city? Steve Hall explained the calculations he has made in attempt- ing to predict this flow of water. Under the existing conditions with the ponding area, it was predicted that development of a maxi- mum of 26 acres would fill the 60" storm drain line to capacity and at that time no further building permits will be issued. But with the development of the Doce's site, the existing ponding area would be destroyed and with the diverting of the creek through a 54" line along South 180th Street and connecting this to the existing 60" line on Andover Park West, the capacity will be reached now. This problem was then presented to the audience for comment. Those present who spoke during this period were: Mr. William Hennessey representing Sammamish Commercial Co. Mr. Jon Stack, Harstad and Associates, who has been employed by Manson Bennett to do the hydraulic calculations on the Doce's/ Lincoln properties Mr. John Flattery, Lincoln Properties Mr. G. John Doce, owner of the Doce's site Mr. Mario Segale, developer of Segale Business Park Mr. Tom Sconzo, Manson Bennett Associates Mr. Charles 0. Baker, Tukwila Industrial Council Mr. Hennessey presented a map of LID #13 constructed in 1968. A portion of the property in question, the Doce's site and the North section of the Lincoln site, were assessed for drainage under this LID. It is their position that they have already paid for their drainage and should be able to develop their property. Again it was noted that the Doce's site will drain into the 18" storm drain on Southcenter Parkway, but with the development of the site, it will block the ponding area for the creek. Mr. Flattery stated that they hoped to start their development shortly so were willing to help fine a solution to the problem. He questioned the building of the 54" line on the North side of South 180th Street to serve the creek and the property South of South 180th Street. Mr. Segale stated that his 100 acres drains into the 60" line on the West side of Andover Park West so that his property will not use the 54" line. Mr. Flattery noted that the Comprehensive Plan shows the property South of So. 180th Street drainage flowing into a 60" line on the East side of Andover Park West. Mr. Stack questioned whether the Council feels that the Doce's /Lincoln development should construct the 54" line on South 180th. He then suggested that the Comprehensive Plan should be updated. Mr. Doce asked that if the Doce's /Lincoln Properties agree to install the 54" line, will this relieve their responsibility. Mr. Tom Sconzo suggested a 10 minute recess which was granted. Mayor Todd called the meeting back to order with all Councilmembers present as previously listed. TUKWILA CITY COUNCIL MEETING April 4, 1974 Page 2 AUDIENCE COMMENTS Cont. ADJOURNMENT 10:50 P.M. Discussion on the storm drainage problems continued at length. Mr. Flattery again questioned if they build the 54" line, will they be able to get their building permits. The eight requirements for a building permit noted in Steve Hall's letter to Barney Ruppert, Building Director, were introduced. These requirements are being incorporated into the plans. Councilwoman Harris stated that the Council should study the ramifications and not accept or reject the suggestion of the Doce's /Lincoln Properties this evening. Steve Hall pointed out the sentence in his March 27th letter, "Also, with the full development of this property and diversion of the creek crossing South 180th Street to Andover Park West single sixty inch drainage system, the capacity will be exceded unless alternatives are provided for storage or ponding of water or contruction of the second storm drain in Andover Park West to handle the additional flows." It was noted that the solution to the construction of the second 60" line on Andover Park West will be settled in court and may take a period of time. Mr. Hennessey stated that they are wait- ing for a trial date. Steve Hall stated that the Lincoln Property to the South cannot build until the question of the 60" line is resolved. Discussion continued. Mayor Todd asked Steve Hall for a recommendation. Steve Hall sug- gested allowing the building of the 54" line but reserving an area for ponding. Mayor Todd requested action from the Council. MOVED BY SAUL, SECONDED BY TRAYNOR, TO INSTRUCT THE CITY ATTORNEY TO DRAW UP AN AGREEMENT, including the points that Mr. Doce and Mr. Flattery made regarding the 54" line and the eight points that Steve Hall wrote to Barney Ruppert plus the finalization on the sanitary sewer.
