MINNESOTA 55101-2140 <br />PHONE:812202.4400 FAXA12M2-0 83. <br />March 1, 1994 <br />Honorable Mayor and City Council <br />Lake Elmo, Minnesota <br />Re: MWCC Centralization/Decentralization Study <br />Lake Elmo, Minnesota <br />Commission No. 9150-940 <br />Dear Mayor and Council Members: <br />On February 23, 1994, the City Planner and myself attended a presentation on the Metropolitan <br />Waste Control Commission's "Centralizatiou/Decentralization (C/D) Study". This stage of the <br />study process is called the Draft Final Report. The purpose of the study is to predict sewer needs <br />to the year 2040 and make recommendations whether the MWCC should continue its present <br />policy of centralized sewage treatment with a few treatment plants or decentralize with the <br />construction of more plants. The purpose of our attendance was to determine if any interceptors <br />and treatment capacity is planned to be provided for at least a portion of Lake Elmo. <br />The preferred alternatives for the East Metro Area call for either a new Southeast Regional plant <br />in southern Washington County at Cottage Grove or a new Southeast Regional plant near <br />Hastings. <br />In either alternative, a new interceptor in eastern Woodbury would stop short of the Lake Ehno <br />border. <br />The study also made a prediction of the sewer needs for that portion of Lake Elmo lying south of <br />loth Street. The area was subdivided into that area west of CSAH 19 and that area east of CSAH <br />19. The following information on anticipated households and sewer flows was provided by the <br />Metro Council and used by the consultants in the C/D Study: <br />Area <br />1990 <br />2000 <br />2010 <br />2020 <br />2030 <br />2040 <br />West of <br />Flow (MOD) <br />.01. <br />.04 <br />.08 <br />.09 <br />.10 <br />.12 <br />CSAH 19 <br />Households <br />24 <br />120 <br />230 <br />266 <br />305 <br />344 <br />East of <br />Flow (MGD) <br />.18 <br />.18 <br />.18 <br />.20 <br />.24 <br />.27 <br />CSAH 19 <br />Households <br />471 <br />500 <br />533 <br />600 <br />695 <br />784 <br />This table shows that for the area west of CSAH 19, the Metro Council shows no growth beyond <br />our present sewer allocation of 0.077 MGD (.08 in table) until after the year 2010. <br />It also shows an existing sewer need east of CSAH 19 of 0.18 MGD (probably Cimarron) <br />holding constant until the year 2010, then slow growth thereafter. <br />
