"The stuff we're decreasing costs a nickel, and the stuff we're increasing costs a dime," Davis said. "We can minimize it, we can offset it, but it won't hide."
Projections show coal will supply 29% of the city's energy this coming fiscal year, compared to 45% 10 years ago.
Davis attributed the planned water rate hikes to the fact that Burbank itself faced a 5% hike from the Metropolitan Water District of Southern California — which provides the city with much of its water — in January. Another 5% hike is scheduled for early next year.
That means the bill for a household using 15,000 gallons of water per month — enough to accommodate a large single-family home "with a pool and gardens," much more than the average household — would jump $2.90 from $64.35, Davis said.
Even so, Burbank's $67.25-per-15,000-gallon rate is among the lowest in the area. Glendale's projected rate for the same amount of water this coming fiscal year is $80.57, while Pasadena's is $74.17, according to a city report.
Additionally, Burbank has kept up with infrastructure maintenance, which saves on costs in the long run, Davis said.
"We build pipe and power lines every day," Davis said. "Burbank has long-standing program to continually maintain and replace infrastructure in a way that minimizes long-term costs."
Sewer and refuse rates are also slated to each jump 2%, officials said.
Public Works Director Bonnie Teaford attributed the hike to ongoing maintenance costs and the rising cost of fuel, which makes trash-hauling services more costly.
The City Council must still approve the budget proposals, for which a public hearing is scheduled on June 4.
