Regardless of what we do now I believe there should be a common rate by the time our debt is repaid in 1992. . A common rate if in place in 1980 would be $5.85 per month (earlier proposed rates were $6.75 City installed and $4.75 developer installed). Closing the Gap As more City installed users come on line the rate differential should gradually decrease (in 1977 the rate differential which could be justified was $1.82 it is now $1.59) but the number of City installed users is not growing fast enough to avoid having a jump in developer installed rates at some point in time if we are to come to a common rate. Another approach which has been suggested a couple of times is to phase in the increase in developer rates over a number of years. A five year phase in, could look like: . 1980 “1981 1982 1983 1984 1985 City Rate 6.75 6.95 7.10 7.30 7.50" 7.65, Increase (3.8%) (3.9%) (2.2%) (2.82%) (2.7%) (2.0%) Developer 4-75 5.20 5.70 6.30 6.95 7.65 ; -Inerease (5.6%) (9.5%) (9.6%) - (10.5%) (10.3%) (10.1%) The $7.65 resulting common rate is based on 54% annual increase on what the common rate would be in 1980 ($5.85). I£ this five year phase in were adopted I would propose to increase the other rates in the by-law by 54s% annually, excepting those which are directly tied to the City installed residential rate. A 54% increase would resujt in almost an 8% increase in revenues with 24 growth rate or a 9% increase witt a 3% growth rate. J. Maitland
