Description: This cross section layer contains the most current cross section locations and floodplain elevations at a Regional Storm event throughout the watershed with the exception of Barrie creeks where no digital information is available. In selected cases the 1:100 year return period information is available. In general estimated cross-section information is available for Ramara, Oro and in isolated locations within Uxbridge and Brock. In general engineered cross-section information is available for York Region, Municipality of Durham, and in Innisfil and Bradford-West Gwillimbury of Simcoe County.
Description: Watercourses are defined as an identifiable depression in the ground in which a flow of water regularly or continuously occurs. Both natural and artificial channels comprise this network in the Lake Simcoe Protection Plan watershed.
Description: The Ontario Regulation Limit 41/24 is mapped as the greatest extent of the Riverine Hazard Limit (Flood Plain/Meanderbelt/Slope/Apparent Valley with a 15m setback), the Shoreline Hazard Limit (shoreline flood hazard/shoreline erosion hazard with a 15m setback), and Wetlands (with a 30m setback from all MNRF wetlands including evaluated, unevaluated, identified). These components have been dissolved to create an ‘all in one’ polygon showing the greatest extent of the regulation limit within the LSRCA Scientific watershed boundary. Refer to “Reference Manual for Determination of Regulation Limits” (LSRCA, November 2005) for more information on determining the extent of the identified hazards.
Description: The Town of Newmarket Zoning data layer contains polygon features representing the various by-law zone boundaries. This data should be used in conjunction with zoning by-law documents. Zoning by-laws are a set of regulations governing land uses that implement the policies in the Official Plan. A Zoning By-law contains specific requirements that provide a way of managing land use and future development that is legally enforceable. It also protects property owners from conflicting land uses.
Description: The purpose of this layer is to help guide infiltration based Low Impact Development (LID) placement within the East Holland River Subwatershed by ranking the subwatershed based on its suitability for infiltration. This layer was developed from interpretations of two input criteria; Ontario Geologic Survey (OGS) surficial geology enhanced by local interpretations (GeolRank attribute field), and depth to water table (WLRank attribute field). Infiltration based LID ranking information is stored in the FinalRank field.
Description: A wellhead protection area (WHPA) is the area around the wellhead where land use activities have the potential to affect the quality of water that flows into the well. A WHPA shows where groundwater is coming from to supply a municipal well, and how fast it is travelling through the ground toward the well. WHPA‐A is a 100 metre radius around the wellhead. WHPA‐B is an area where water and any pollution that may be present can reach the well within 2 years. WHPA‐C is an area where water and any pollution that may be present can reach the well within 2 to 5 years. WHPA‐D is an area where water and any pollution that may be present can reach the well within 5 to 25 years.
Description: Since 2003 the Town of Newmarket has had a ward system of representation on Town Council. This system contains seven wards, where residents vote for the Councillor they want to see represent them in their ward during municipal elections.
