Report No.: PWE 050-16 Meeting Date: December 7, 2016 Submitted by: Brian Lima – Director, Public Works & Engineering Subject: Application of Stormwater Management Rates in Designated
Settlement Areas
Recommendation: THAT the Application of Stormwater Management Rates in Designated Settlement Areas report be received for information. Purpose: To review the application of the Stormwater Management Rate as it is applied to the Municipality’s urban growth boundary settlement communities as defined in the Municipality’s Official Plan. Background: On October 19, 2016 the Municipality of Middlesex Centre Council passed the following resolution: “THAT during the 2017 budget review of the storm water rates, that Council re-examine the stormwater charge as it applies to the Urban Designated (non- serviced) areas.” Related Reports: February 17, 2016 PWE 011-16 - Stormwater Management Rate Implementation Plan Analysis: BMA Management Consulting Inc. was engaged in 2015 by the Municipality of Middlesex Centre to undertake a stormwater financial review. The purpose of this report was to provide an overview of the options available for the Municipality to fund its stormwater management program and to make recommendations in the recovery of stormwater management costs based on best practice research. The report also calculated the proposed rates using the 2016 Operating and Capital Budget provided by the departmental administrative staff.

Middlesex Centre’s stormwater infrastructure includes stormwater ponds, storm sewers, catch basins, maintenance holes, oil grit separators, culverts, roadside ditches, and municipal drains. As the owner and operator of stormwater infrastructure, the Municipality is responsible for ensuring that the system is operational which will provide an appropriate level of flood protection for all properties. Stormwater infrastructure requires ongoing maintenance and capital work including but not limited to blockage removal, concrete repair, sediment removal, and rehabilitation and/or replacement. The intent of a stormwater pond is to provide flood control, water quality treatment and erosion control. Design standards for these ponds continue to evolve. Over the years, the design of stormwater ponds has advanced from a dam built across a river (online pond) to a wet pond constructed near the river (offline pond). Storm sewer sizing criteria is also changing, as municipalities adapt to the variability of extreme weather events expected in the future. Due to ongoing development and change of design standards, there is a need to rehabilitate our ponds or sewers so that adequate flood protection can be provided in accordance with changing design criteria established by approval agencies. Middlesex Centre’s stormwater infrastructure exists at various lifecycle stages, and continues to evolve and age. As sediment is collected in a pond, concrete structures, or existing urban municipal drains continue to degrade, the ability of the infrastructure to provide adequate flood control decreases. To meet evolving regulatory requirements and protect the various settlement communities from storm events that could cause flood damage to persons or property, the Municipality must conduct ongoing infrastructure monitoring, operate and maintain these services, and provide for capital replacement programs as required. As such, a sustainable, predictable, and proactive funding source is required to be maintained necessary to support the Municipality’s stormwater infrastructure and the programs necessary to maintain and replace it over time. The Municipality’s Asset Management Plan, dated December 2013, estimated the replacement cost of the stormwater infrastructure at $53.2 million. Further, the recently completed Delaware Community Settlement Area Stormwater Master Plan identified up to $7.0 million of needed stormwater infrastructure improvements alone. A comprehensive stormwater management program is very capital intensive and cannot be successful without a consistent, dedicated source of revenue on which it can rely. Financial Implications: The current funding approach for stormwater management is that all properties within the Municipality’s settlement urban growth boundary limits as defined by the Municipality’s Official Plan (please refer to Appendix “A” for mapping attached), dated May 27, 2015, which includes Poplar Hill / Coldstream, Denfield, Lobo, Melrose, Ilderton, Birr, Bryanston, Ballymote, Arva, Komoka – Kilworth, and Delaware pay a $14.88 monthly flat rate ($178.61 per year) for stormwater management services to fund stormwater management

and infrastructure costs. Industrial, commercial, and institutional properties also pay $14.88 per month and for all hectares above the 0.4 hectare threshold, such properties contribute an additional $42.18 per month. These rates are applied based on property types and use as identified by the Municipal Property Assessment Corporation in the annual assessment roll; and are based on all information known at this time, including lifecycle reserve needs for all existing stormwater infrastructure inventory and estimates of lifecycle reserve needs for known facilities to be assumed by the Municipality. The total quantity of properties currently affected by the Stormwater Management Rate is 4,299 and as of the last bi-monthly billing cycle generated $140,801.78 in reserve funds. The Stormwater Management Rate is a stable, predictable, and dedicated source of funding that is used to undertake maintenance, rehabilitation, and capital upgrades of the Municipality’s stormwater management system; which includes and is not limited to, roadside ditches, catch basins, laneway culverts, storm sewers, stormwater management ponds, etc. With anticipated Provincial regulations expected to be announced in 2017, it is expected that more municipalities in Ontario will be moving to a dedicated stormwater rate in the future.
