This report is an in depth policy review and analysis of Option 7 within the MHBC Hastings Drive Issues & Options Report 2016. Option 7 consists of single family detached seasonal cottages on private vacant lots throughout Hastings Drive. This report is prepared by a Hastings Drive Private Land Owner and is for Norfolk County. The site is adjacent to Lake Erie (see Figure 1.1) and is subject to flooding and dynamic beach hazards associated with high lake levels and wave action. This report has assessed the flood and dynamic beach hazard in accordance with Ontario Regulation 178/06 Development Interference with Wetlands and Alterations to Shorelines and Watercourses and the Provincial Policy Statement (2014).
Section 2 of this report provides an overview of the key coastal conditions. The shoreline hazards, within the context of the regulatory framework, are defined in Section 3. The approach to addressing the hazards is presented in Section 4, including the protection works concepts.
The MHBC Hastings Drive Final Issues & Options Report specified that if residential development is decided to be the preferred option (Option 7), the County or Private Landowners may be required to complete an Environmental Impact Study and/or obtain a Ministry of Natural Resources and Forestry permit under the Endangered Species Act to support any development. The requirement and responsibility for completing these technical studies will be established upon implementing the preferred option. This option may also require additional amendments to the Official Plan before a new By-law can be enacted.
At the May 10th, 2016 Public Meeting, Norfolk County Council had a majority vote to explore further planning components to Options 5 (Seasonal RVʼs) & 7 (Development). As a result, a Hastings Drive private lot owner has done a flood and dynamic beach hazard assessment within the regulatory framework on Hastings Drive.
The dynamic beach allowance is intended to permit the natural erosion and accretion of the natural beach/dune system in response to variable lake levels and storm events. The Technical Guide (MNR 2001) requires a dynamic beach allowance of 30 m if no study using accepted engineering and scientific principles is undertaken. However, the Technical Guide allows that where a cliff or bluff, consisting of cohesive sediments or bedrock, exists landward of the beach, the toe of the bluff/cliff acts to limit the landward extent of dynamic beach profile adjustment; in these areas the dynamic beach hazard limit should be defined as the toe of the cliff or bluff.
Similar to the case of a beach backed by a fixed cliff or bluff, the longstanding, shoreline protection along most cottages and private vacant lots on Hastings Drive limits the practical extent of the dynamic beach to the base of the shore protection. This is also the case at many other properties in the Long Point area.
