This enables the Council an� -�-�ther_s_to_ estimate the: use of each system el��,�ent and to anticipate future bottlenecys and needed improve- r.;ents. Te do this, the Counci.l ras diviced the '•'etrepolitan Area into traffic assignment zones (T:AZ) . Orono has five as sho�,an on tne enclesed ,;ap. There are five especially important demogrzphic variables used in the process: total households, total population, total e�ployment, retail emplo��ent , and service, financial, insurance, and real estate employ:uent. More than any other variables they dictate the gross magnitude of trips which are produced or attracted by a TAZ. Changes in any of these five variables will measurably affect trip ��.aking characteristics of a zone, whereas Iarge variatior.s in other demographic �ariables will have only a roargir.al effect. Tl�us, when the Council revised its forecasts of total housenolds, population, and emploj-r.ient last December, three of the five critical variables were chan�ed and resulted in the revised traific fore- casts for your system state�ent. The attached copies of computer printouts show the demographic variables used to make the traffic estimate sent in Orono's original system statement. They are broken down by TAZ, and a decoding sheet is also included. Except for revised figures for total households, population, and employment the variables are the same for the updated 1990 traffic estimate of 44,000 person trips per day which you recently received. The 44,000 figure assumes the forecasts of total households, population, and employment enclosed with the December 28, 1977 letter, i.e. , the most current forecasts. At the present time Council transportation staff are re- evaluating all the" original assumptions in light of the new forecasts to determine if other variables should also be changed. If after reviewing this information you feel the City can provide more accurate data, please contact Steve i�mediately so it can be considered. In conclusion, this information should allow us to clear the books on several items currently pending between the City and the Metropolitan Council. First, I recoT.mend that the Council review the Waste Control Commission's plans and speci- �ications for the Orono-Long Take Interceptor as soon as possible. �+'e would like . to present a report to the Physical Development Committee on March 23. We would mail it to you and the Co�ittee on March 17. Second, I reco�nend the City amend the interim comprehensive sewer plan previously submitted for Waste Control Commission review to include the revised 1990 urban service area �ap which you just sent us. Shortly thereafter the interim CSP review can be completed. I emphasize interim CSP because the immediate objective is to plan service for the three to five year period following construction of the Orono-Long Lake Interceptor, leaving finalization of plans for the period to 1990 for the comprehensive plan Orono is preparing pursuant to the Land Planning Act. Third, if the City wants to request a hearing on its ?ietropolitan system state�ent, you should file a request according to the Planning Act by March 23. Since the Planning Act provides no mechanism for extending the local system statement review period, it is irnperative for the City to make its decision by then. I believe that all the important infor- mation on sewer flows, traffic generation, and growth forecasts has already been sent to Orono and included in the system statement. If, however, there is a need to amend �etro s��stem plans as a result of tne above Council revieks, appro- priate system plan amendments will be proposed.
