January 16, 1978 at 7 30 p m Chairman Battin, Mr Bailey, Mr Buse, Mrs Miley, Mr Kent; Mr Hutchinson, Town Manager; Mr Cohen, Town Counsel; Mr McSweeney, Director, Public Works/Engineering, were present Mr Myles Barnert, Chairman, and members of the Capital Expendi- Capital tures Committee met with the Board to discuss Capital budget items Expenditures The following recommendations were made Committee Sewers $400,000; $2 million bonding with assurance that the Selectmen come back to Town Meeting on what areas they will be doing, but not be limited to those on a year- to-year basis in case packages might be available Drainage $34,000 Water Mains $25,000 Curbs & Sidewalks $34,000 Streets $150,000 for three streets (Will recommend $100,000 in the future) Chapter 90 Recommended DPW Equipment $125,000 I & I and Drainage Studies Recommended Fire Department Equipment $20,000 Conservation Committee's position is whatever Town Meeting wants Recreation $40,000 for pool study We support the pool, for plans this year and construction next year Bicycle Paths Because of the possibility of one-time funding, the committee recommends up to $100,000 as long as only $25,000 is on the tax rate Westview Cemetery $100,000 Sanitary Landfill $20,000 Recyclables Article recommended - $45,000 Mrs Joan Crothers, Chairman, and members of the Sewer Advisory Sewer Committee met with the Board to discuss the committee's report Advisory Committee SEWER ADVISORY COMMITTEE PRELIMINARY REPORT TO THE BOARD OF SELECTMEN January 16, 1978 During the past six months the temporary Sewer Advisory Committee has reviewed matters relating to the extension and maintenance of Lexington's sanitary sewer system, as requested by the Board of Select- men in May, 1977 We submit these findings and suggest that our report be considered the first in a continuing citizen advisory process of sewer service delivery 120 Selectmen's Meeting January 16, 1978 The scope of our review has followed the five part list of topics suggested in the Selectmen's charge, which requested specific advice on 1) reasonable objectives for substantial completion of the system, 2) viable alternatives to the community collector system, 3) procedures for establishing desire/need for sewering, 4) possible betterment formula adjustments, 5) financial information on costs of conventional sewerage compared with on-lot subsurface wastewater dis- posal In addition, we comment on the proposal for capitalization through bonding of the remainder of the system which is presently under consideration, but was not contemplated at the time this com- mittee was formed Lexington joined the North Metropolitan Sewerage District of the Metropolitan District Commission in 1899 when a 15" interceptor sewer with a design capacity of 2 8 million gallons per day (mgd) was extended to the Arlington/Lexington boundary to receive our municipal sewage By 1953 a 20" interceptor designed to carry 5 7 mgd was necessary, and this was supplemented by another 36" line with 27 3 mgd design capacity in 1968 These increases to our outflow capability were a result of the town's policy of providing municipal sewerage facilities to as many residents as possible with the result that now 86 4% (7,304) of our dwellings are serviced as of March, 1977 The remaining 13 6% (1,151) are not sewered, of which 6% (488 houses) do not have sewer available We understand that sufficient capability is available in the MDC system, which has a design capacity of 35 8 mgd, to handle Lexington's maximum flow calculated at approximately 12 5 mgd (Bedford included) A fourth collector sewer which would cross through Lexington for the exclusive use of Bedford is now under consideration by the MDC Expansion of our local system has been continuous since 1899, but has come into question primarily because of the increasing costs associated with sewerage The town's responsibility to provide a community sanitary sewer to all occupants is uncertain as the un- precedented high costs place an overwhelming tax burden on the prop- erty owners Investigation of past projects shows that the commit- ment to sewer has always involved a financial liability by the town which was not recoverable, and constituted a deliberate subsidy in the public interest Betterments, i e , reimbursements to the town by private parties, have been based upon several variables These include the average per foot costs of lateral sewers over the previous five years, lot area according to the total limit of work for the pro- ject, and a setback calculation This assessment formula assumes that 50% of the cost is borne by abutters, divided between the two sides of the street, with the remaining 50% paid by the town (1/4- 1/4-1/2), This subsidy plus the betterment constitute the major financial support for local sewerage projects Occasionally state and federal funds are available for portions of the municipal system (notably the Woodhaven trunk and the Hanscom Field force main) 121 Selectmen's Meeting January 16, 1978 After detailed analysis of sewer assessments (Table 1) we find that betterment cost recovery percentages have dropped during the last five years Although these calculations are not as accurate as we would like because they are based on aggregated numbers which include non-betterment projects, they are useful as a comparison and show that the percent of actual sewer cost recovered is con- tinually lessened This is due to the tripling of construction costs, the costs of trunk sewers and other capital costs, and the cost of building sewers past town-owned land The percentage re- covered might increase if an adjustment factor for eventual service connection payments is included; these are backcharged to abutters at the time household connections are made However, it must be emphasized that we are unable to establish that our current better- ment assessment practices have ever realized the assumed 50% cost recovery As the cost of sewering has roughly tripled per lot in the past five years (Table 2), and approximately 448 homes are presently with- out access to sewer service, it is necessary to decide if an expendi- ture which (based on a per lot average of $6,000) could amount to at least $2,688,000 should be made in order to accommodate our entire existing population (with the exception of 67 houses which it has been determined are impractical to reach) In order to arrive at a recommendation the committee requested a comparison of the existing 1/4-1/4-1/2 five year average method In a random sampling of final assessments from actual sewer projects the new formula showed a greater than 50% reimbursement giving the town a more equitable rate of return In each case the old method returned less than 50% These results (Table 3) point out that the three year average of previous costs and a 1/3-1/3-1/3 plan of assess- ment keeps the estimated cost closer to the actual cost of sewer con- struction The new method also shows greater tolerance for the time lag between assessment and completion of construction Of all communities investigated (Bedford, Belmont, Boston, Needham, Wakefield, Wellesley) it was clear that sewer cost recovery percentages vary according to local policy For instance, Wellesley charges a flat rate per lot which does not attempt to cover costs Boston, on the other hand, collects about 3/4 of the costs of its sewers The consensus of this committee is to suggest that if the Selectmen de- cide to implement the substantial completion of our sewerage as de- fined by the DPW/Engineering priority list dated November 21, 1977, they consider changing the betterment formula in order to allow the town to regain a larger portion of the total financial outlay The Selectmen could achieve this goal by averaging costs over three years and reducing the town's share to 1/3 as illustrated It would also be possible to change only the three year timespan while continuing to use the 1/4-1/4-1/2 formula In the latter case this action would not necessitate a change in the language of Chapter 221 of the Acts II/ of 1926 which would be needed otherwise A majority of this committee 122 Selectmen's Meeting January 16, 1978 favors the final alternative Other methods of sewer cost recovery which were discussed and re- jected include imposition of a cost ceiling above which the town would refuse to sewer an area, imposition of a flat rate charge to abutters for sewering lots above a certain pre-determined rate, and assessing specific projects without averaging (which would have the effect of forcing some homeowners to pay premium prices for their very expen- sive sewers) Procedures to be followed in establishing need and desire for sewering should include a preliminary sign-up with the Selectmen who would forward requests to DPW/Engineering for cost estimates Board of Health participation as defined in Title V of the State Environ- mental Code would continue; it should emphasize proper maintenance and rehabilitation of on-site systems It could provide citizens with financial information based upon typical Lexington projects of septic system as well as conventional sewerage A booklet could be prepared describing the petition process and the assessment formula as well as information on the care of septic tanks and other allow- able methods of handling failing systems such as humus toilets (clivus multrum) In order to arrive at an estimate of the relative dollar costs of conventional sewerage versus septic tanks, the costs of staffing and operating a septic system management program with full municipal control and equipment ownership were reviewed This was based on a community with 3,000 existing septic systems (roughly twice the amount now functioning here) as reported by the Metropolitan Area Planning Council Water Quality Project (Table 4) Their total of $70,000/yr should be reduced for a smaller service load Billings to owners would vary from $20 each if 1000 systems were serviced to $50 per cleaning when annual service totals 400 jobs With federal assis- tance in purchasing a pumper truck, the costs decrease about 20%, ranging from $16 to $41 per job Since town-owned pumpers are totally user supported they may exceed average private fees if less than 600 tanks are pumped annually Therefore, Lexington might best utilize contract services combined with municipal inspection to provide the most economical combination of private and public management The possibility of developing a septic system management program of some sort should be given consideration in order to accommodate the exist- ing homes which will never be serviced by municipal sewerage under any plan The committee is unable to recommend this exclusively as an alternative to the substantial completion of our system as there are current regulatory obstacles to communal septic tanks in Massa- chusetts Although the proposal to expand and complete the sewer system by means of a bonding authorization has not been presented in detail, we feel that this may be a justifiable action to take We would suggest that more, not less, review of sewer projects should be pro- 123 Selectmen's Meeting January 16, 1978 vided and that a permanent sewer advisory committee should be appointed by the Selectmen to assist in sewerage planning The selection of sewer project priorities affects the development of the town and in- volves judgements of where the need is greatest These effects of sewering should be reviewed and discussed During our brief span of operation the committee has received nine unsolicited letters in addi- tion to a number of telephone calls and conversations with citizens regarding sewer problems We believe that this indicates a real need to increase contact with townspeople as the complicated design and political aspects of sewering are addressed Another recommendation of the committee is that applications for permits for building additions or alterations should be checked by the Board of Health to determine if the existing septic system is adequate Similar information should be supplied by the Board of Appeals for variances and special permits We also feel that there should be a clear plan for the proposed sewers with precise statements, topographical maps, and estimated costs Laterals should be identified separately from trunks and interceptors Cost figures should allow for inflation In the plan the highest priority projects should be identified It was beyond the range of this investigation to consider the economic effects of the revised MDC billing system which will be U based on volume rather than number of connections Sewer use charges should be considered in cost analyses of system expansion, and would provide a fertile area of inquiry for additional advisory reports We wish to thank staff members of the DPW/Engineering, Board of Health, Town Manager, and Board of Selectmen offices for invaluable assistance as well as many citizens for helpful contributions In particular, Julian Bussgang has spent considerable time studying and clarifying cost figures on the Lexington sewers This opportunity to examine and discuss the variety of issues and practices relating to sanitary sewage installations and related matters has been extremely interesting We thank the Board of Se- lectmen for giving us the chance to prepare this report, and look forward to augmenting these comments should it be deemed necessary Joan Crothers, Chairman Gordon Barnes Katherine Fricker John

try to pick up the recent $2 million bonding, for which we had a minimum of information We focused on the betterment formular (the Committee points out that costs recovery via the betterment formula has not accomplished what some of us thought) and how the proposed bonding would pertain to that formula We had some question about the advisory capacity of the Town Meeting, and we felt that their review should be based on a very specific priority and map plan, so that the Town Meeting would have a careful understanding of the proposal The committee feels that the map has insufficient information on how it would be bonded 125 Selectmen's Meeting January 16, 1978 Mr Bailey said that it was recommended at Town Meeting last year that we create a permanent advisory committee We opted to create a temporary advisory committee and we gave a very specific charge, which got to the core of the difficulty we were having with Town Meeting, and the report we got back doesn't help us any further in solving the credibility problem of Town Meeting than it did a year ago Dr Nill, Sewer Advisory Committee, said that on the first charge, the committee all agrees that we would like to finish sewering to some reasonable point On the second charge, there really aren't many al- ternatives Mr Bailey said that what you would like to have done is to have the whole Category A Streets complete engineered and each batch pre- sented to Town Meeting It will take us a long time to engineer all of them, and what we tried to do was bite off bits and pieces, depend- ing on what the pressures are of that year, and engineer them and con- struct them. Otherwise, if we are going to do it all at once, we are going to have to get it all put together now, sell the whole $2 million - fully engineered right now - and then deal out the money and the programs over five years Dr Nill said that we want to know conceptually what areas, how would you start the first year, what would you do the second? He did not think it is required at all that the engineering be done It was suggested that this statement be put in writing Dr Nill said that the problem the Board is going to face is that at some point you do all of Category A and you declare the Town's sewer system complete (by definition), what do you do to the person who has a septic system that fails and you say that you are sorry but the Town is finished and we won't entertain your petition The Board agreed that anyone can petition Mr Hutchinson said that it is entirely feasible that somebody in Section C could come before the Board two years from now and say that he needed help, and perhaps some groups in Section A might be fine and not have a problem We would then consider the problem area Mrs Crothers asked if the bonding is a complete spending situa- tion or is it possible for some unknown reason that it could be termi- nated? Mr Hutchinson replied that it is an authorization for the Board of Selectmen to address the sewer planning of the Town and to go for- ward and execute it After further discussion, the Sewer Advisory Committee agreed to submit conclusions and recommendations to the Board Mr Martin, Assistant Town Engineer, explained types of sewer projects which might be combined over the next three to five years Upon motion duly made and seconded, it was voted 5-0 by roll call Executive vote to go into Executive Session, with no intention of resuming the Session open session, for the purpose of discussing strategy with respect to 126 Selectmen's Meeting January 16, 1978 litigation After discussion, it was voted to go out of Executive Session A summary of a recorded meeting Respectfully submitted, j Executive Clerk, Selectmen
