Explanation
Background: This ordinance authorizes an increase in sanitary sewer service rates for the Division of Sewerage and Drainage.
The Department of Public Utilities entered into contract in 2005 for development of updated rate models for the Division of Sewerage and Drainage and the Division of Water. This was the first major review and rewriting of rate models since 1993. The new models follow accepted design practice and fully account for changes in operations and asset valuations for each division. Customer cost of service was established and cost of service rates established for each customer group.
The proposed rate configuration for 2006 recognizes that sewer charges disproportionately effect lower income groups and continues a Low Income Discount program that discounts participant's sewer commodity portion of their quarterly bill by 15%.
Requested adjustments in rates result in a typical inside city residential sanitary sewer rate increase of 19.09%. When a water increase of 10% and a Stormwater increase of 8.5% are considered the overall impact on a typical residential customer in the City of Columbus is 14.99% and for an outside city residential customer 10.24%.
The proposed rate structure also includes a charge related to each customers contribution to wastewater flow during periods of wet weather. Since wastewater flow during wet weather directly corresponds to impervious area, rates include a charge to recover costs of construction of projects necessary to meet the requirements of the two consent orders that mandate elimination of wet weather flow from Combined Sewer Overflows and Sanitary Sewer Overflows. This charge is assessed based on each property's measured impervious surface area. Each Equivalent Residential Unit (ERU) is based on the previously determined Stormwater ERU of 2000 sq ft. Residents are charged at one ERU per residence. All other customers are charged based on measured impervious area divided by 2000 sq ft to determine an ERU equivalent. This charge is calculated to recover the debt service costs and other expense of all projects related to correcting wet weather overflows. It is also established that no customer will be charged for more than 1000 ERUs. This charge for 2006 is $1.31 per ERU inside city and $.51 per ERU for outside city customers. ERU charges for 2007 will be $2.34 per ERU inside city and $1.39 per ERU for outside city customers.
Fiscal Impact: These rate increases will generate approximately $29.6 million in additional revenue in 2007.
Title
To amend Chapter 1147 of the Columbus City Codes 1959, to enact new sanitary sewer service rates for the year beginning January 1, 2007, and to repeal the existing Section being amended
Body
WHEREAS, it is necessary to establish new sewer sanitary services rates, effective January 1, 2007, for sewerage services to properties discharging into the sanitary sewerage system of the City of Columbus in order to recover the cost of rendering said sewerage services for the calendar year; and
WHEREAS, the City of Columbus is committed to establishing its rates based on a cost of service basis, where the rates charged to customers are based as closely as possible on the cost of servicing that customer. The rates established herein are based on a rate study that used the cost of service methodology; and
WHEREAS, in addition to the commodity rates, City Council finds it necessary to continue a sewer surcharge to fund the wet weather capital improvement projects required by the Consent Order with the State of Ohio.; and
WHEREAS, City Council finds that the most appropriate way to assess the wet weather improvements surcharge is by correlating the surcharge to the amount of impervious surface, as the factor most closely associated with increased inflow and infiltration is impervious cover from urban development and
WHEREAS, the City already uses impervious cover to establish stormwater fees. The Columbus Stormwater Management Program assigns one (1) Equivalent Residential Unit (ERU) to each residential property regardless of size, and 1 ERU for every 2000 square feet of impervious cover for all other properties. City Council finds that, for purposes of the wet weather improvements surcharge, ERUs should be capped at a maximum of 1000 regardless of the size of the property; and
WHEREAS, City of Columbus customers should participate in funding for all of the wet weather projects. Outside customers should not be assessed for combined sewer or priority area projects; and
WHEREAS, City Council finds that inside City Customer should pay a west weather improvement surcharge of $2.34/ERU/month, while outside customers should pay $1.39/ERU/month; and
WHEREAS, City Council recognizes that increased water rates disproportionately impact low income residents. Low income residents already pay a higher percentage of their household income in utility bills, and this percentage would increase with higher rates; and
WHEREAS, City Council further recognizes that past rate increases in the City have demonstrated that increasing rates leads to increased delinquencies among the City's customers; delinquencies rates are higher among low income residents. It is well recognized that increased delinquencies are expensive for the City and its customers; and
WHEREAS, City Council finds that continuing a discounted rate for low income users is a recognized method for helping to alleviate the impacts of increased water rates; and
WHEREAS, the Sewer and Water Advisory Board has adopted recommendations that are consistent with the rates established in this legislation; and
WHEREAS, City Council finds that the rates, surcharges and the low income discount established are equitable to all of the City's customers; now therefore
BE IT ORDAINED BY THE COUNCIL OF THE CITY OF COLUMBUS:
