The Council approved the recommendation of the mayor that the following named people be appointed to constitute a Library Board: Mrs. J. T. Duncan, Mrs. Owen Lee, Mrs. Eugene Rush, Mrs. F. L. Thomas, .Mrs. L. P. Dulaney, Mrs. A. W. Melloh, Mr. Raymond Rogers, and Mr. L: S. Richardson, and Mr. M. L. Cashion, Sr. On motion by Orr, seconded -by Halpin, the following named people were appointed to the College Station Cemetery Board: Mrs. D. W. Williams, Mrs. J. C. Miller, Mrs. T. W. Leland, Mrs. F. G. Anderson, Mr. W. S. Edmonds, Mr. N. M. McGinnis, chairman. The mayor was instructed to notify the various members of their appointment and to request that the board formulate a general policy concerning the operation. df the cemetery and recommend a procedure for appointing members of the board in the future. On motion by Badgett, seconded by Fitch, the council accepted- and approved the report of Messrs. Orr, Benson, and Orman,rela.tive to an agreement between the -City of College Ststion and the City of Bryan for the treating of sewage in the north gate area and directed the City Manager to procedure to make the agreement effective. A REPORT SHOWING THE ESTIMATED PI CAPITA COST OF TREATING BRYAN'S SEWAGE AND THE RECOMMENDE',D PROVISIONS FOR AN AGREEMENT BETWEEN THE CITY OF COLLEGE STATION AND THE CITY OF BRYAN FOR TREATING THE SEWAGE THAT THE CITY OF 06LLEGE STATION WOULD CONTRIBUTE TO THE SYSTEM. FIRST: ; Due to the fact that Bryan's Sewage Treatment Plant has only been in operation for approximately two months, the monthly cost of operating this plant cannot be accurately determined from experience.. Therefore, it was thought best to take 1/12 of the annual budget allowance as set forth in the 1949-50 Budget for this figure or 1/12 of $21,175..00 or $12765.00 per month. From the records of the ttility Department it was determined that there were approximately 3900'sewer connections to the system. Considering that there are 32 persons to each connection, the total population served is (3900) (3.5) or 13,650 persons. Taking the above two figures, the per capita cost of treating sewage is 130 per month. Minutes of Janu iry 9, 1950 page 2 SECOND: A copy of Mr. Homer Hunter's "Sanitary Sewer Study For the North Gate Area" is attached hereto and is made a part of this report. From this study of Mr. Hunter's has been accepted the fact that the College Station area that would contribute to this system is 142 acres. He has used a. population density figure of 10 persons per acre, which would -make Pn eventual population for this area of 1420 persons. It is impossible to say when this Prea will reach this population. This area has developed rather slowly in the past but once sanitary. sewer facilities are available, it may develop at a.much greater rate. An actual count of the houses in this area revelas that there are 125. A, great number of these are already sewered into the A. & M. College system. This applies particularly to the houses and • buildings along Sulphur Springs Road, or what is commonly called the North Gate Area. Assuming again that there is an average of 31 persons per house, the total population for this area at the present time is 438. However, it has been estimated that not more than 15 of these houses would be connected to the new system when it is constructed. It is not anticipated that the A. & M. College will require the houses that are now sewered into their system to discontinue that service in the near future because they are able to treat this sewage and too, they are collecting the monthly service charge for this treatment. Then at the very best, only some estimates can be made as to the population growth of this area and the rate that they would connect to thenew system. Two approaches to the problem have been made. No. 1. Assuming that the 142 acres in the College Station area were fully populated to the 1420 persons, the cost of treating the resulting sewage would be $2,215.20 per yesr. The cost of installing that portion of the line by College Station is estimated to be $10,760.00. Under these conditions it would require nearly five years for the treatment of the sewage to pay for the line. No. 2. However, since the area is not fully populated, an estimate of the number of persons that will be connected to the system at the end of each year is shown below,.together with annual cost of treating the sewage: Year 1950 1951 1952 1953 1954 1955 1956 1957 1958 1959 Estimated.

Recognition must be taken of the fact that should the two cities choose to put in separate lines, the cost of slach a line to Bryan would be approximately $9,500.00 (due to the reduced size of pipe needed) and College Station's cost would be increased to an estimated $13,820.00 (due to the necessity of building a lift station). By -making it a joint project, both cities will realize a savings and it is not believed that the additional load will affect the operation of Bryan's sew-ge treatment plant. RECO11MENDATIONS 1. That the'City of College Station build and maintain a sanita.ry sewer main of sufficient size and design to transport the sewage .from the 116 acres in Bryan and the 142 acres in the College St, -tion area ff'om the alley east of Old Highway No. -6 on First Avenue to a point at'the west property line.of Howell Boulevard (all as shDwn on the attached drawing of said line). -Plans and specifications of this line shall be approved by the City of Bryan} prior to construction. 2. Since the City of Bryan will have -to construct laterals to connect to this main to serve the Bryan population and since a portion of these laterals will be within the confines of the City of College Stntion, it is agreed to by,the City of Bryan, that the City of College Station will be allowed to connect onto these laterals for the use of their customers and the per capita cost of treating their sewage shall be as hereinafter provided 3. That the City of Bryan shall treat the sewage from this area of. the City of .College Station free of charge until the end of 1959, PROVIDED HOWEVER, that should the population in this area reach 1420 persons by the end. of 1954, that the -period of .free treatment shall extend only through the end of 1956. 4. At the.end of the period of free treatment, the City of.College Station agrees to pay to the City of Bryan at the end of each calendar year, the cost of treating the sewage from the City of College Station based on the per capita cost of treating such sewage and on the population at the end of the calendar year.' 5. The City of College Station agrees that not more than 400 connections will be made to the system and that all of these will be confined to the area of 142 acres as shown on the attached map.

CONSULTING ENGINEER DALLAS, TEXAS COPY COPY 00301 � '� Minutes of January 9, 1950 page 5 Sanitary Sewer Study North Gate Area City of College Station, Texas Recommendations - It is recommended the City of College Station construct the necessary 8?t and 10" mains from the alley east of Old Highway No. 6 on First Avenue to a point at the west property line of College Avenue. This will be a•gravity sewer and it will be necessary for the City of Bryan to construct a line of proper size from the lower end of this line to connect with their existing. outfall line to the new sewage treatment plant. An agreement should be made with the City of Bryan to treat all sewage, as long as both cities exist, from*the part of the City of College Station that can be Served by the 811 and 10" mains. Bryan will construct laterals from the mains to the area served which is within their city limits. Since Bryan will be required to construct these laterals which will have their origin in the City of College Station, it will be desirable to also have an agreement that the City of College Station can connect their customers on the laterals built by Bryan. There should be no additionPl cost to the City of.College Station for the connection to a. Bryan lateral as long as it is within the city limits of College Station. The cost to the City of College Station for the cooperative pro- ject is estimated to be $10,760. Area Served - The area served by the proposed main is approximately 116 acres in the City of Bryan and 142 -acres in the City of College Station. It will not be possible to include additional area in the future since the Texas A. & M. College bounds the area on the south and west and beyond the northern limits of the area involved in this study the natural drainage is to the north into.a different drainage area. The area to be served by the proposed sewer is shown in Exhibit I. Population - A population density of 10 persons per acre served has been used in this study since there should be no large apartment hoi.ises or houses built on small lots which would increase the popula- tion density. This ultimate population in the area to be served in both cities is estimated to be approximately 2550. Infiltration - Infiltration in the amount of 40,000 gallons per day per mile of main and lAteral has bedn used in determining the max - MUM wet weather flow of sewage. Flow of Sewage - The average daily flow of sewage was determined by using the maximum assumed populption of 2550 persons times one hundred gallons per day. The peak flow to be expected is 225 percent of the average daily flow which is,550,000'ga.11ons of sewage per day. Six miles of main and laterals were used as a basis to determine the infiltration which added 240,000 gallons per day. The peak flow plus infiltrPtion used in the design of the -sewer is 820,000 gallons per day. '302 �� Minutes of JannPry 9, 1950 page 6 Main Sewer - An eight inch sewer will be adequate for the first 1850 feet of the main when both -rea.s are connected. Reyond this point, a. ten inch main will be required to carry the flow. Since the pump station is located at Station 18/50, there will be very little dif- ference in cost of this main to serve one or both cities areas. The main to serve both cities must be deeper th^n the main to serve the City of College Station only. Comparative costs of the sewer required to serve the City of College St -tion anO the sewer to serve both cities is as follows: M ER TO SERVE CITY OF COLLEGE STATION OhTLY Cost of 811 sewer from Station 0/00 to Station 1850.

A factor thpt has not been taken into consideration in computing the saving is the annual p»mping cost. This pumping cost, if the.aver- age design flow from the -ity of College St -tion area only is used, will be approximately $400 per annum and capitalized at 4% for 25 years would be $6,250. This figure should be added to the $3,000 saving to give a true picture of the. difference in cost of construction and oper- ation of the separate system. The actual saving will be $9,250. Conclusions - Since the construction cost of the line to serve both cities is less than the cost of constructing a separate system to serve the area of College Stption involved.and pumping into the A. & M. College sewer system, it will be an advantage to both cities if the City of College Station can build the 3150 feet of $" and 101 sewer and the City of Bryan agree to treat the sewage without cost from the areas involved asUong as the two cities exist. The City of College Station should stipulate in the agreement with Bryan that any laterals built by the City of Bryan within the city limits of College Station will be accessible to the City of College Stntion at no charge. This condition will probfbly exist since the 8" and 101' main is within the city limits of College Station the entire length. It will be necessary for Bryan to construct laterals from this main sewer to the area within their city limits and College Station should be allowed to tie on their customers without additional expense. Minutes of January 9, 1950 page S On motion by Halpin, seconded by Orr, Ordinance No. 139 'was approved and a public hearing was ordered for the even-i.ng of .February 13,' 1950. On motion by Orr, seconded by Badgett, Ordinance No. 140 was ap?)roved and ordered published. On motion by Orr, seconded by Fitch, Ordinance No. 141 was approved and ordered -published. The -mayor was instructed to prepare a proclamation declaring an emergency,'to have it published in all papers and to give. it to the radio stations. City Manager Rogers was instructed to prepare a form of contract to be used -in making water extensions outside the city limits and to have it presented to Councilman Orr and City Attorney Barger for approval and consideration the next regular council meeting. The City Manager was also directed to remove all signs permitting center parking along Farm Highway 60 between Old Highway 6 and New Highway 6 and to advise all parties concerned that center parking would no longer -be permitted. A request from the Catholic Church for a closing of an alley on property which the church had recently purchased was tabled until the next regular meeting of the council. The mayor reported that he had had a conference with the president. of the collene relative to extension of electric lines and services in the College Hills area rind that he was advised that inasmuch as the college was already selling electric power to the city there.'was no need of further contract documents relative to -the extension of lines within the city. The City Manager was instructed to begin studies and to make such surveys as are necessary to extend electric lines into this area. APPRO ,D : Mayor ATTEST: City Secretary w
