Engineering Plan Review

NVCA’s Engineering Department provides technical support in review of permit and planning applications.

NVCA staff have prepared Engineering Technical Guidelines that help to assess the suitability of proposed developments within the watershed. Appropriate technical guidelines should be referenced for all applications submitted. The use of the NVCA’s technical guidelines in the preparation of planning and permit applications is encouraged.

Development Review Guidelines

The Engineering Development Review Guidelines provide engineering consultants with background information on what the NVCA looks for in stormwater, natural hazard and erosion and sediment control submissions.

Stormwater Management Review and Approvals

The NCVA engineering department provides technical review of stormwater management reports and engineering plans for municipal site plan approvals, plans of subdivision or condominium. The NVCA has developed a series of submission procedures, technical standards and tools to assist the consulting engineer with the development and submission of reports. Engineers are encouraged to check back here with every new project, as improvements or new tool versions may have been posted.

Hydrogeological Assessment Submission Guidelines

This guidance document provides information on the hydrogeological assessment submissions which may be required as part of a development application. It is a resource to assist the consulting community in understanding the conservation authority’s perspective regarding potential watershed impacts and the requirements expected in a hydrogeological assessment.

Phosphorus Loading Development Tool

This online tool provides a generic approach for assessing pre- and post-development phosphorus loadings from new development in the Nottawasaga Valley watershed.

Floodplain Management

New development can be constrained by the existence of floodplains on the site. Where floodplain mapping does not exist, or requires updating, the NVCA usually requests the preparation of a floodplain study to determine the extent of flooding on the development site and to model any proposed waterway crossings.
