Title

An Ordinance to Amend Sections 2:61 through 2:64, and 2:69, and to Repeal Section 2:73 of Chapter 29 (Change Water, Sewer, and Stormwater Rates) of Title II of the Code of the City of Ann Arbor (Ordinance No. ORD-18-12)

Memorandum

Your approval is requested to amend Sections 2:61 through 2:64, and 2:69, and to repeal Section 2:73 of Chapter 29 of Title II of the Code of the City of Ann Arbor to adjust water, sewer, and stormwater rates and charges. The structural and price adjustments for water and sewer are a result of a comprehensive cost of service and rate design study for water and sewer (2017). The rate adjustments for stormwater are based on a level of service study conducted for stormwater (2016). 

 

The last water and sewer cost of study was conducted in 2003, and rates and other charges have been indexed annually since then, but no cost of service adjustments have been made since the last study. In 2017, the City retained Stantec Consulting Services to provide their expertise in utility engineering and financial services. In compliance with the requirement that rates and charges be based on the costs to provide the services, the available data regarding those services and costs were collected and analyzed. The data included the patterns of water and sewer service usage by customers, including data regarding different types of use by different categories of customers, along with data regarding the costs to provide those services. The review and analysis of the data, and the principle that charges must be based on the cost to provide service, resulted in the proposed changes to Chapter 29 regarding charges to rate classifications, and changes to charges for water and sewer services. Based on the analysis, the rates and other charges were adjusted to align with the cost to serve each rate classification.

 

The study also included public feedback through focus groups and a public advisory committee, and a survey. The Environmental Commission also recommends adoption of the changes.

 

The recommended changes include updated nomenclature as well as structural changes to the rates and charges paid by customers. Terminology changes include changing “commercial” to “non-residential,” and the addition of a “multi-family” rate class. 

 

The structural changes include the new multi-family rate class for properties with more than two dwelling units that formerly were classified as either commercial or residential, and the addition of a fourth tier to the inclining block rate structure for the two rate classes for residential customers. Tiers for the non-residential class were replaced with a uniform (flat) rate. The new multi-family rate also was established as a uniform rate, and the water only rate remains as a uniform rate. All of the foregoing decisions are based on the analysis of the data that were

 

Differences in the customer charges between commercial and residential customers were eliminated.

 

The impact of these increases on an average single-family residential customer is $19.29 per quarter or $77.16 per year, a net increase of 10.96%, if consumption is unchanged from last year. For the purpose of this comparison, the single-family bill is calculated with 18 units per quarter, is in the second tier for stormwater, and receives the 10% discount for payment on or before the due date.

 

Other language changes are made for clarity.

 

This ordinance will take effect on July 1, 2018.
