CONSULTING ENGINEERS <br />1107 FLEETWOOD DRIVE - BAYTOWN, TEXAS 77520 - PHONE (713) 422.8213 <br />October 20, 1975 <br />Honorable Mayor Pro Tem and <br />City Commission <br />City of La Porte <br />Post Office Box 1115 <br />La Porte, Texas 77571 <br />SANITARY SEWER SERVICE TO THE AIR NATIONAL GUARD AND OTHER AIRPORT <br />FACILITIES <br />As requested, we have prepared an estimate for the construction of <br />the referenced project. The proposed line would be eight inch (8"J <br />diameter vitrified clay pipe extending from the vicinity of Cl i`ff <br />Hyde Flying Service west to a point opposite the intersection of <br />Spencer Highway and Farrington Boulevard. Unless a more detailed <br />study dictates otherwise, the line would be installed on the north <br />side of Spencer Highway. The line would cross Spencer Highway and <br />• tie into the Fairmont Park sanitary sewer system at the end of <br />Farrington Boulevard. Provisions would be made for service con- <br />nections at appropriate locations along Spencer. <br />The estimated cost of this work is $32,900.00 including engineering. <br />The attached letter, although over a year old is still valid as <br />regards the Air National Guard's willingness to enter into negotiations <br />with the City to determine an amount they will contribute toward the <br />project cost. Paragraph 2 of the letter mentions 1,900 linear feet <br />of 12" to 15" diameter line; manholes at 400 foot intervals and 350 <br />linear feet of 8" lateral line. Our review of the existing facilities <br />shows that the largest line available to tie into in Fairmont Park is <br />an 8" which remains that size for several blocks south of Spencer <br />Highway. For this reason, an 8" line is proposed in this project and <br />this size is adequate for the projected use of all the airport facili- <br />ties. Our standard design for manhole spacing in La Porte is 500 feet <br />and we would recommend this be followed here. No service lines are <br />included in our estimates, assuming each user will construct his own. <br />The reason 1,900 feet is mentioned in the letter is because that is <br />the distance from Farrington Boulevard to the Air National Guard <br />building. Our design calls for service to be extended another 1,600 <br />feet to reach near the east side of the Airport property. <br />• <br />
