Others Present: S/W Supt. Van Dyke, Surveyor Zavodny. MERIDIAN ROAD C. Hopkins reported the Public Works Committee met three weeks ago and the general consensus was to not proceed on the Meridian Road project immediately since the contingencies had not been resolved. In the interim, Mayor Kennedy directed DPW Hammer to prepare a design/proposal to begin the project this year. The Public Works Staff has prepared for the Sewer and Water Committee meeting on August 4, 1989 a schedule of construction and maintenance. At the Sewer and Water Committee the Public Works Staff was instructed to purchase materials for storm drain. The resolution of storm drainage was a contingency item. The staff designed a solution to a long standing problem at Mr. Pittman's residence on 7th St. W. and loth Ave. W. The opportunity exists, according to the schedule presented, to install a portion of the water main and storm drain for Meridian Road. This combined Committee is to consider the Committee recommendation of withholding action on Meridian or to go forward with the project. The installation of storm drain on 7th St. W. to the outfall has been decided in favor. C. Nystul stated one of the issues to discuss is the storm drain materials. He reported S/W Supt. Van Dyke and Surveyor Zavodny have been discussing two different types of sewer pipe. S/W Supt. Van Dyke stated SDR 35 conventional sewer pipe was to be installed on 7th to Mr. Pittman's residence. He is proposing to use a new type of pipe called Perma Loc. It has been on the market for eight years. The City of Whitefish has used approx. 3,000 ft. of this pipe in the same increments as the staff is proposing; 12", 18", and 24". If the City of Kalispell uses this pipe it will save an estimated $8,000. He has contacted three of the major engineering firms and all of the engineers have stated that the pipe is afceptable. In addition, he has spoken with Greg Aktin and a foreman from the City of Whitefish, a local pipe layer and has not received negative comments regarding Perma Loc pipe. The pipe is lighter, more brittle, and requires more careful handling. The only negative comments he has received are from the suppliers who do not sell this product. He stated the storm drain budget is tight and by using this pipe there will be enough funding available to finance the project in 1989-90. C. Furlong questioned the advantages other than cost. S/W Supt. Van Dyke responded cost is the advantage. The disadvantage is that it is more brittle, not as flexible, but if care is taken in the bedding it holds up well. C. Saverud questioned if there is more than one supplier. S/W Supt. responded one supplier is Iron & Oak of Kalispell and Northwest Pipe of Billings. Surveyor Zavodny stated the City crews will be laying this pipe. He stated he is more negative than S/W Supt. Van Dyke, only because the pipe is not time tested. The pipe the City is currently using is time tested. C. Nystul questioned the amount of cover that is available in the first three blocks. Surveyor Zavodny responded the first two blocks from 7th to 9th have 4.5 to 5 feet of cover. From 9th to loth it will drop to the depression. From loth Alley W. to Meridian there is a minimal cover, but the pipe will then be 18" and not 24". C. Hopkins questioned the depth Whitefish placed Perma Loc. S/W Supt. Van Dyke responded Whitefish used 6' of cover and the minimum recommended cover is 3'. Surveyor Zavodny stated 3' of cover is available. C. Saverud questioned the budget for the savings of $8,000. S/W Supt. Van Dyke stated the Meridian project total for storm drain is $80,000. Other financing options may WOOS/SEWER AND WA-Ihlt UWgIiiiiLL miLiuiLi AUGUST 7, 1989 PACE 2 be available. This is one way to meet the budget requirements. Surveyor Zavodny stated S/W Supt. Van Dyke and he are split on the decision of the •pipe. If DPW Hammer were present, he might have decided and this may not have been brought to Committee. Neither Surveyor Zavodny nor S/W Supt. Van Dyke have this type of authority. C. Nystul stated it would be advantageous to use this pipe from 7th St. to Meridian. Meridian will be a concern due to traffic. C. Nystul questioned which contractor has used this type of pipe. S/W Supt. Van Dyke responded the foreman for LHC has used the pipe in California. He stated he believes this pipe can be used for storm drain and can be jointed. For sewer pipe, which needs to be water tight, he would be scepticle. The Committee agreed to begin the project using the Perma Loc pipe. C. Furlong stated if he can be assured that the Meridian Road project will be finished next year, then he is in favor of finishing as much of the preliminary work that can be done now. He questioned the portion of Meridian Road proposed to be completed. Surveyor Zavodny responded the staff believes the portion from Center to 2nd St. W. would have water main installed by wintertime and possibly go further if weather prevailed. C. Furlong questioned when curbing could be installed. S/W Supt. Van Dyke responded he is projecting May 15, 1990. C. Furlong stated that if the road could be prepared for curbing and asphalt this year •the temporary base will not be worse than the existing roadway. He is in favor of beginning on Meridian now. C. Nystul stated Street Supt. Brady was asked to prepare a memorandum regarding interim maintenance. The Committee then reviewed the memo. Surveyor Zavodny stated that in the first paragraph the price to pave an asphalt leveling course for $14,200.00 is only 1.5" overlay, 24 feet wide. The trucking and labor, using five City personnel; two City trucks and drivers, three laborers, two rental trucks for five days is $6,000.00. The cost to accomplish a temporary street is $20,000.00. If the asphalt is stripped and crgshed gravel is placed and oiled, the cost will be $7,000.00 materials only. It is estimated that between the end of August and the beginning of the construction season it will cost an additional $6,000.00 for watering and grading. Based on the available data, his recommendation would be to do nothing. Surveyor Zavodny stated most of the issues of contingency have been resolved excepting curbing and sidewalk. The staff has provided the options requested by Mayor Kennedy. C. Nystul stated the reason he is not in favor of beginning the project now is based on the unresolved contingency issues. C. Nystul questioned the right of way available. Surveyor Zavodny responded there is enough right of way for 34' including curb and gutter. Right of way is 40' plus or minus. The unresolved issue is who will pay for curb and gutter. C. Nystul complimented the design of the cross section of the road. He questioned the funding for the street portion of the road. Surveyor Zavodny stated the costs are not calculated for City manpower and trucking, and does not know what money is budgeted for materials. He is unsure of County participation at this time. PUBLIC WORKS/SEWER AND WATER COMMITTEE MINUTES AUGUST 7, 1989 PAGE 3 Discussion took place regarding the installation of storm drain pipe on 7th St. W. C. Nystul. questioned if the water line was designed in-house. Surveyor Zavodny . responded yes, the project is for water main replacement. The approximate $20,000 saved will be used to buy pipe. C. Nystul questioned if there were any objections to the storm drain installation. There were none. SOMERS TO KALISPELL C. Furlong questioned if the project will be four or five years in the future. C. Nystul responded the inquiry of the Highway Dept. states this as being five years. He stated he has a problem with the standard agreement in that it states, "The City agrees to make a thorough investigation of its existing storm sewer needs in the areas adjacent to the proposed project, determine if facilities for intercepting storm runoff are required before reaching this proposed project.". In addition, why is the City responsible for advising the power, gas, phone, etc., it is a highway dept. project. C. Nystul stated more importantly and not included in the agreement are the design criteria such as trees on Main Street, median strips and landscaping from the Courthouse to the south end of the City, left turn lanes, etc. The Committee agreed negotiations are needed before signing an agreement. S/W Supt. Van Dyke requested a Sewer and Water Committee meeting before August 21, 1989. Agenda items are mostly for updating. C. Nystul reported NW Telephone has submitted a bill and they had over -estimated their billing by $10,000. The'City's engineer for the lst Alley W. project has recommended a $95.00 reduction for a patch on the alley. The Mayor has written his disagreement for the reduction on the bill. C. Nystul stated he believes $95.00 should not be deducted. C. Furlong stated he is in favor of the $95.00 deduction. Adjourned: 7:27 P.M. ss 40
