Thunderhill Development Engineering Assessment of Public Works


The Thunderhill Subdivision was constructed around 1968, as part of the Castle Glen Estates Limited development, consisting of 87 lots serviced by a gravel rural road and a sanitary sewer collection system discharging to a private wastewater treatment lagoon. Individual private wells and cisterns are used for water supply.

The road allowances within the development are municipally owned however the Town (previously the Township of Collingwood) has not assumed the Works as municipal infrastructure. These Works consist of an open ditch and granular rural road network. A privately owned and operated sanitary system is located in the road allowance to collect sewage for delivery to a privately owned wastewater treatment lagoon.

Routine maintenance of the roads and ditches has been completed by the Castle Glen Development Corporation (CGDC)  who is the current Developer of the lands surrounding the Thunderhill Development. CGDC is also the owner/operator of the sanitary system.

In 2011, CGDC informed the Town that it would no longer maintain the roads. At the request of the Castle Glen Ratepayers Association (CGRA), a group of property owners within the Thunderhill Development, the Town has undertaken routine maintenance on a cost recovery basis from the Thunderhill Development lot owners.  In addition, the CGRA has asked the Town to assume the roads and sanitary collection system. The Town’s position is that the Public Works must be improved to a state such that the Town can assume the Works as municipal infrastructure. The improvement will be cost recovered from the property owners.

The purpose of this engineering assessment is to review the existing condition of the installed infrastructure, describe various standards that the Town can consider to enable municipal assumption of the road and related infrastructure and the sanitary collection system (not including the wastewater treatment lagoon),  to recommend preferred alternatives, and recommend the cost recovery mechanism.

Public Meeting Dates:

A Public Information Centre will be convened on Saturday June 28, 2014 to provide a review of the condition assessment, infrastructure improvement alternatives and recommendations resulting from the Engineering Assessment, and to outline the possible cost recovery mechanisms.
