Very truly your /, s w. City Clerk CITY OF $AINT PAUL - MINNESOTA 8 f � GEORGE M. SHEPARD .,R. STREET AND HIGHWAY ENGINEERING COORDINATOR CITY E V AVERY ENGINEER September 27, 1962 f Hon. George J. Vavoulis, Mayor and Members of the City Council City of Saint Paul Gentlemen: On August 1, 1962, the Council referred to the Technical Committee the matter of connecting certain proposed sewer facilities in the City of White Bear Lake to the St. Paul sewer system. On August 31, 1962, the Technical Committee recommended to the City Council that favorable consideration be given to permitting the City of White Bear Lake to connect to the St. Paul sewer system at the Belt Line Sewer in the vicinity of Johnson Parkway and Jessamine Avenue. In amplifying its recommendation, the committee noted that the physical work would be done in accordance with suitable detailed plans to be approved by the City of St. Paul, that all direct and related costs of construction or installation of the complete facility would be borne by the City of White Bear Lake and that the annual rental and main- tenance charges by St. Paul to White Bear Lake would probably be on the same basis as to other outlying communities. The matter of charges, of course, is a matter for Council determination and the committee made no definite recommendation. On August 31, 1962, at the time that the Council considered the Tech- nical Committee's report, the Mayor of the City of White Bear Lake appeared before the Council to indicate that his community is generally inclined to favor a plan involving connection to the St. Paul sewer system rather than a local or regional expansion. However, he stated that connection to the St. Paul system would involve greater expense than solving the problem locally and he distributed copies of cost tabulations indicating that the cost per year per connection in White Bear would be $21.80 for expanding the present facilities. The comparable cost annually per connection per year was estimated to be $34.50 if -the solution of connecting to the City of St. Paul were used. In the latter cost estimate, the cost of a force main from the City of White Bear Lake to Jessamine and Johnson Parkway in St. Paul was included as were the usual annual charges which St. Paul bills to other communities for sewer rental and maintenance. The Mayor of White Bear Lake stated that the City of White Bear Lake still has on its present plant a 20 -yepr debt of some $322,300.00 for an annual debt cost averaging some $21,476.00. This plant would be withdrawn from use in the event that - 1 - N r f the City of White Bear Lake connected its entire system to the St. Paul system. In consideration of this debt and of the substantial additional cost of connecting to St. Paul rather than solving their problems locally, Mayor Newcome asked that the St. Paul City Council give favorable consider- ation to permitting a connection at a point farther north than Jessamine Street in St. Paul and that they consider favorably a reduction in the annual rates which St. Paul would charge per connection. After further discussion, the City Council referred the matter of the point of connec- tion back to the Technical Committee for further study and referred the matter of the sewer rates to the Mayor's Sewer Study Committee. The Technical Committee first considered the matter of the point of connection. The sewer involved is a combined sewer carrying both storm water and sanitary flows. It must, therefore, have sufficient capacity not only to carry normal sanitary flows, but also surges of storm water. Various points of connection involving changes in sewer capacity were investigated; these were at Arlington and McAfee, Jessamine and Johnson Parkway, Mechanic and the Belt Line Sewer, Margaret and the Belt Line Sewer and Point Douglas and the Belt Line Sewer. It was found that south of Jessamine and Johnson Parkway the sewer system has sufficient design capacity to convey the tributary sanitary flow, including that of White Bear Lake, as well as the maximum amount of storm flow from the tributary area caused by a storm which would occur, with statistical probability, once in ten years. This is the standard consistent basis of design for the entire sewer system and using the same approach for possible connec- tion at Arlington and McAfee, it was found that design capacity at this point would not be sufficient to handle these maximum range storms. It was pointed out that while the additional sanitary flow from the City of White Bear Lake would constitute a relatively small part of the total flow, it did constitute a major part of the total sanitary flow and thus the strength of sewage would be considerably increased this having a definite bearing on the objectionable character of the material in the event of any flooding. The Department of Public Works recommended against any connection to the Belt Line Sewer north of Jessamine. It was pointed out that the ten -year storm could occur at any time, even several times in one year. It was pointed out that in the event of any flooding, the fact that the City of White Bear Lake was connected would have an adverse public relation implication. It was further pointed out that the addi- tional cost of the force main from Arlington to Jessamine would amount to only some 76� per connection per year, based on the present number of connections in the City of White Bear Lake. The committee, therefore, concluded that if the present combined sewer system is continued in the area, they could not recommend connection of a White Bear Lake force main at any point north of Jessamine Avenue. They would thus reiterate their previous recommendation. However, continuance of a combined sewer system in the area is not the most desirable physical arrangement. A separation of storm and sanitary flow in an area east of Lake Phalen and south of Larpenteur with the storm water flow being conveyed to Lake Phalen would be a much better system. - 2 - This would involve construction of additional storm sewers in St. Paul with the present sewer lines being used for sanitary flow only. In the event this were done, there would be ample sanitary capacity for the City of White Bear Lake even at Larpenteur Avenue. Therefore, the Technical Committee concluded that if the City of White Bear Lake would participate appropriately in a St. Paul separation project, a connection could reason- ably be permitted at Larpenteur Avenue. An approach to the problem involving connection to St. Paul, storm - sanitary separation in an area east of Lake Phalen and south of Larpenteur, and abandonment of the present White Bear plant has many advantages, including ample sanitary capacity, additional water to Lake Phalen, reduced flows to the Minneapolis -St. Paul Sanitary District plant, protection of St. Paul water supply, and a substantial additional step to control and reduce lake and river water pollution. Since the matter of participation by the City of White Bear Lake in such a project is tied up with the matter of rates, a joint meeting was held with the Mayor's Sewer Study Committee. At this joint meeting, the nature of the various designs were reviewed as were the related matters of sewer rental and sewer maintenance rates, White Bear Lake costs, advantages to all parties, including the public, for a separation project and the possibility of additional areas contiguous to the City of White Bear Lake joining in to be connected to the White Bear Lake force main, thus substantially increasing the present number of connections. Cognizance was taken of the fact that all parties concerned would benefit from the abandonment of the White Bear plan, but that outstanding debt on the plant constitutes a serious problem for White Bear in that these costs are added to the costs of connection to St. Paul. In consideration of these further deliberations, the Technical Com- mittee and the Mayor's Sewer Study Committee recommends the Council's favorable consideration to a procedure and a set of conditions approxi- mately as follows: I. That in lieu of extending the proposed force main from Larpenteur to Jessamine, the most northerly recommended point of connection in the combined system, the City of White Bear Lake be permitted to connect at Larpenteur and McAfee Streets with payment of a connection charge to St. Paul, estimated to be on the order of $75,000, and calculated to be equivalent to the sum of all costs of constructing a force main from Larpenteur to Jessamine, said costs to be estimated on the basis of actual bids on similar work to the extent available. It would be understood that said payment is to be applied by St. Paul to an area sewer separation project to be under- taken by St. Paul as soon as the necessary plans can be prepared and that until the project is completed, White Bear would be requested to take necessary measures to refrain from pumping at certain specified critical times until the separation project is completed. Said connec- tion charge should be paid to St. Paul prior to the award by St. Paul of a construction project for the separation. wic Y It is contemplated that the separation project would be con - structed and completed concurrently with the White Bear force main. It is also contemplated that the costs of all facilities necessary to pump sewage from White Bear to St. Paul would be borne by White Bear, that the maximum peak flow authorized would be 3.73 cubic feet per second, and that the facility to be constructed at White Bear expense would include a suitable metering device. 2. That in the event the City of White Bear Lake elects to connect its entire system to that of St. Paul, the scale of annual charges to the City of White Bear Lake be on the same basis as to other outlying communities, but that the total annual charge paid by the City of White Bear Lake be reduced by an annual credit equivalent to the actual amount paid for debt service by White Bear Lake on its presently existing treatment plant, such annual credit not to be allowed unless the entire White Bear Lake sewer system is connected to the St. Paul system and the presently existing treatment plant withdrawn from use. Said annual debt service considered for said annual credit shall be the amount of principal and interest as certified to the County Auditor at the time of the issuance of presently outstanding bonds for sewage treatment plant revisions and shall not include any outstanding debt service or further debt service or any other part of the sewer system. 3. That all plans, policies, coordination and other details relating to or incidental to the general policy expres- sions outlined in Items 1 and 2 above, shall be arranged to the satisfaction of and subject to the approval of the various St. Paul city departments involved, and in the event of general approval of both cities, shall be embodied by the respective corporation counsels, assisted by other city departments as necessary, into an instru- ment for formal execution by the respective city councils. It is suggested in the event the Council approves the general approach to the problem, as outlined herein, that the matter be referred to the Corporation Counsel and the Commissioner of Public Works for further, more detailed development and further consideration by the Council at a later date.

Schroeder Re: St. Paul - White Bear Lake Sanitary Sewer Connection Gentlemen: On September 18, 1962, the City Council of the City of White Bear Lake resolved to submit to the City of St. Paul a formal request for sanitary sewer connection to the City of St. Paul. In connection therewith, we request to be connected to,the City of St. Paul sanitary sewer. We also submit the following specific recommendations: 1. White Bear Lake shall pay for the costs of all facilities required to pump sewage flow from White Bear Lake to St. Paul City Limits. The point of connection being at Larpenteur Avenue and McAfee Street. 2. The capacity request for White Bear Lake shall be 3.73 cubic feet per second. 3. The City of White Bear Lake shall make a connection charge payment to St. Paul equal to the cost of extending the force main at bid unit prices to Jessamine and Johnson Parkway. The unit price per foot times the distance from Larpenteur basically would be the proposed formula. 4. The City of White Bear Lake shall pay the same rate as other suburban contracted municipalities for sewer rental. 5. The City of White Bear Lake shall pay the same rate as other suburban contracted municipalities for maintenance but shall receive a credit on the maintenance billing equal to the annual payments on present outstanding debts on the sewage facilities. 6. If peak shaving, storage in sewers for emergencies, or cooperative measures for protection of downstream sewage facilities in St. Paul are required, White Bear Lake shall provide such items as mutually agreed upon. Your early attention is requested. Yours very truly, Edward G. Springer EGS:ts City Attorney City of White Bear Lake
