Cartografía y estudios

Wetlands are the most biologically diverse kind of ecosystem, as they support both aquatic and terrestrial plant and wildlife species. These ecosystems provide a range of benefits, such as flood management, water quality improvement, groundwater replenishment and climate resilience, as well as recreation and economic opportunities, such as for timber, hunting and fishing.

Conservation Halton uses wetland mapping to identify potential wetlands and to determine if a property may be regulated by Conservation Halton. Conservation Halton regulates all watercourses, valleylands, wetlands, Lake Ontario and Burlington Bay shoreline, and hazardous lands, as well as lands adjacent to these features. Up-to-date mapping supports the delivery of our regulatory and planning programs and helps ensure wetlands are protected.

A report was brought to the Conservation Halton Board of Directors on Junio 23, 2022. The engagement period began Julio 13, 2022 and closed on Septiembre 13, 2022.

The following are next steps that will be taken for this project:

• Staff is currently reviewing all comments received and is making edits to the mapping, where necessary.
• Where requested, staff is completing site visits to ground truth the mapping.
• Final draft mapping will be taken to the Board of Directors for approval in the new year.

Actualización de la situación reglamentaria de Lower Rambo Creek

La ciudad de Burlington ha completado recientemente la fase 1 de la evaluación del riesgo de inundación y de la gestión de las aguas pluviales en el centro de Burlington y en la zona de la estación de tránsito principal de Burlington GO (MTSA). El estudio de la fase 1 ha revelado que el riesgo de inundación en la cuenca del Bajo Rambo es mayor de lo que se pensaba. Actualmente se está llevando a cabo un estudio de fase 2 para perfeccionar la cartografía de riesgo de inundación, pero el estudio de fase 1 se considera la mejor información disponible para la toma de decisiones cuando se contempla el desarrollo en zonas peligrosas.

En virtud del Reglamento 162/06 de Ontario, Conservation Halton regula todos los cursos de agua, los valles, los humedales, el litoral del lago Ontario y de la bahía de Burlington y los terrenos peligrosos, así como los terrenos adyacentes a estas características. El objetivo de la normativa es proteger a las personas y los bienes de los riesgos asociados a los peligros naturales y evitar el empeoramiento de los peligros existentes o la creación de nuevos peligros. La normativa de Conservación Halton se aplica ahora a los peligros de inundación (es decir, zonas de inundación y vertido) y erosión identificados, así como a un margen de regulación de 7,5 metros, en la cuenca del arroyo Lower Rambo. Se requiere un permiso de Conservación Halton para urbanizar en estas zonas.

Para más información sobre la Fase 1 o la Fase 2, póngase en contacto con el personal de la ciudad de Burlington.

Conservation Halton (CH) is updating flood hazard mapping for Tuck, Shoreacres, Appleby, and Sheldon Creeks in your community.

Flood hazard mapping is an important tool that supports CH’s regulatory, planning and flood forecasting and warning programs, as well as municipal emergency management, flood mitigation, and infrastructure design.  Advances in technology allow us to understand flood risks and develop better flood hazard mapping.

Flood hazards include floodplains and spills.  A floodplain is an area of land that is flooded with water by a nearby creek or lake during large storms. Spills occur when flood waters leave the valley and floodplain and “spill” into surrounding lands, rejoining the watercourse at a distance downstream or moving into another watershed.

One of CH’s top priorities is to protect life and property from natural hazards and updating hazard mapping is one of the ways we do that.

In 2021, CH retained the engineering consulting firm WSP, to update the flood hazard modelling and mapping for Tuck, Shoreacres, Appleby and Sheldon Creeks which cross through parts of east Burlington and southwest Oakville (referred to as ‘East Burlington Creeks Flood Hazard Mapping Study’).  Updated mapping and modelling provides CH, municipalities, the public, and stakeholders with a current understanding of the magnitude and extent of riverine flood hazards in this area.   The study also provides background information and technical details about how the riverine flood hazard modelling and mapping was updated.

In Octubre 2021, CH hosted a public engagement session to provide notification of study commencement and provide an opportunity for property owners, residents, and other stakeholders to ask questions and share feedback.

Public Engagement Session #2

To learn more about the study and updated draft flood hazard mapping, you are invited to join us for a virtual public engagement session on Junio 6, 2023 at 7:00pm.  This is an opportunity for those looking for further information to learn more and ask questions.  To register for the virtual public engagement session, please click here: https://us02web.zoom.us/webinar/register/WN_sl19iHNURcerow1W3mK8PQ

If you are unable to join us, draft mapping and reports, as well as a recording of the public engagement session, will be available online for comment until Julio 6, 2023.  CH will review all feedback and make any necessary revisions to the draft flood hazard mapping.  It is anticipated that the final draft mapping and study will be presented to CH’s Board of Directors for their approval and inclusion in CH’s Approximate Regulation Limit (ARL) mapping later this year.

Should you have any questions about the study or upcoming Public Engagement Session #2, please contact us via email at floodplainmapping@hrca.on.ca or call (905) 336-1158 ext. 2296.

Conservation Halton has retained consulting and engineering company, Greck and Associates, to update flood hazard mapping and modelling for the West Branch of Sixteen Mile Creek in the Town of Milton. Advances in technology allows us to better understand flood hazards and to develop more accurate floodplain mapping. One of Conservation Halton’s top priorities is to protect life and property from natural hazards and updating flood hazard mapping is one of the ways we do that. An important part of the process of updating flood hazard mapping is to inform and engage with residents and other stakeholders in the study area.

Flood hazard mapping is used by Conservation Halton and municipal partners to identify areas that may be susceptible to riverine or shoreline flooding, and to inform flood forecasting, emergency response, community planning, infrastructure upgrades and other flood prevention efforts. Flood hazards include floodplains and spills.  A floodplain is an area of land that is flooded by a nearby creek or lake during large storms. Spills occur when flood waters leave the valley and floodplain and “spill” into surrounding lands, rejoining the watercourse at a distance downstream or moving into another watershed.

Conservation Halton hosted the second public engagement session for the Urban Milton Flood Hazard Mapping Study in Marzo 2020. A summary of the study and draft mapping presented at that time can be found here: Urban Milton Flood Hazard Mapping.

Public Engagement Session 3

To learn more about the Urban Milton Flood Hazard Mapping Study and updated draft flood hazard mapping, Conservation Halton staff held a virtual public engagement session on Febrero 22, 2023.
