PURPOSE

The purpose of this report is to provide Council with a summary of the Watershed Plan for Duffins Creek, to inform Council of the management recommendations, implementation strategies and roles and responsibilities established for the municipality with respect to the Duffins Creek and Carruthers Creek Watershed Plan and to endorse, in principle, the Watershed Plan. 

 

EXECUTIVE SUMMARY

The Duffins Creek Watershed extends into the Town of Markham at its eastern boundary and encompasses lands on the Oak Ridges Moraine.  The Federal Government owns the majority of the lands (see ‘Federal and Provincial Holdings’ map in Appendix ‘A’).  The Watershed Plan has identified eight goals, twenty-five objectives and one-hundred and seventy–two actions to be achieved in the watershed and recommends an approach for managing the Duffins and Carruthers Creek watershed.  The Watershed Plan responds to the requirements of the Oak Ridges Moraine Conservation Plan, to the extent feasible, given the Provincial technical requirements have not been finalized.  The Watershed Plan will also need to be consistent with the forthcoming Provincial requirements for source water protection.  The document provides a strong basis for protection of the watershed and offers an integrated management approach. 

 

BACKGROUND

Duffins Creek encompasses a small portion of lands in eastern Markham

The Duffins Watershed extends into Markham at its eastern boundary and is generally bounded by Highway 7 in the South, the municipal boundary in the North and East, and Reesor Road in the West.  The affected land in Markham encompasses approximately 3.1% of the Duffins Creek watershed and is approximately 874 hectares in area.  These lands are predominantly federally and provincially owned.  The lands in the north portion of the watershed are within the Oak Ridges Moraine.  The lands within the Oak Ridges Moraine are owned by the Federal Government and subject to the Federal Green Space Master Plan process.  The Federal Government has indicated the Duffins Creek and Carruthers Creek Watershed Plan has been considered as input into their planning process.

 

TRCA commences Duffins Creek and Carruthers Creek Watershed Strategy

In spring of 1999, the Toronto and Region Conservation Authority (TRCA) began developing a watershed plan for the Duffins and Carruthers watershed as part of the continuing effort under the 1989 Green Space Strategy to develop a watershed plan for each of the nine watersheds in its jurisdiction.  The purpose of the watershed strategy is to provide an integrated, customized management framework for natural systems protection, restoration, environmental education, outdoor recreation and cultural and heritage planning activities.  Once completed, the watershed strategy will assist in identifying features worth preserving, where development may be appropriate, and best management practices for open space and green space corridors.


 

Town of Markham supports the Duffins Watershed Strategy planning process

The Town of Markham contributed $5,000 towards for the preparation of the Watershed Strategy.  Council appointed Councillor Erin Shapero to the Duffins Task Force.  Regional Councillor Tony Wong represented the Region of York.  The TRCA created two task forces – Duffins and Carruthers consisting of elected municipal representatives, watershed residents, and representatives from key stakeholder groups and agencies.  The Task Forces also included representatives from the Aggregate Producers of Ontario, the golf course industry, Urban Development Institute and members of the agricultural community. These two task forces met separately to address site-specific issues but prepared one Watershed Management Plan because many of the same opportunities and challenges exist for both Duffins and Carruthers Creeks.

 

Duffins Creek and Carruthers Creek Watershed Plan endorsed by the Duffins Task Force

Extensive consultation has occurred throughout the development of the Watershed Plan, involving numerous public open houses, working group sessions, site tours and meetings with special interest groups and municipal staff.  In June 2003, the Task Force endorsed the Watershed Plan for the Duffins Creek and Carruthers Creek, with the understanding that TRCA staff would continue to work with municipal planning staff to fine-tune the wording of the Plan and to continue discussion regarding implementation of the Watershed Plan.

 

THE WATERSHED PLAN

The Executive Summary for the Watershed Plan for the Duffins Creek and Carruthers Creek is attached as Appendix ‘A’.

 

Duffins Watershed Plan identifies a vision, goals and objectives 

The purpose of the Watershed Plan is to evaluate the potential effects of current and future watershed activities and to identify management actions needed to mitigate the anticipated effects and enhance the watershed.  The Duffins and Carruthers Creek Watershed Task Forces have defined a vision for the future of the watersheds as places that are healthy, dynamic, sustainable and that support clean, safe water.   The vision is supported by five key elements:

·        net gain;

·        environment first;

·        balanced land use;

·        human health and safety; and,

·        ownership commitment, and follow through. 

The Watershed Plan provides a framework of management strategies, including eight watershed management goals, twenty-five objectives and the required actions to fulfil the objectives.  Some of the objectives include increasing natural cover, maintaining water balance, minimizing in-stream sediment and improving water quality.  Environmental indicators and targets for each objective are also recommended.  The Watershed Plan also presents implementation mechanisms and direction for establishing priorities at a sub-watershed scale.


 

Duffins Watershed Plan identifies specific management actions

The Watershed Plan identified 172 management actions required to fulfil the objectives.  The management actions are grouped into the following common areas:

  1. Protect existing meadows, wetlands, and forests identified in the enhanced terrestrial natural heritage system and secure lands to be restored.
  2. Actively restore areas within the enhanced natural heritage system, which contribute multiple watershed benefits, and allow passive restoration to occur in the remaining areas.

3.      Provide stormwater quantity and quality controls for new and existing development, including transportation corridors.

4.      Manage land uses and water withdrawals to maintain or enhance infiltration patterns, groundwater pathways, and resultant baseflows.

5.      Eliminate the remaining point source of pollution (i.e. Stouffville Water Pollution Control Plant) and manage non-point sources of pollution, in particular stormwater runoff and infiltration from urban land uses, transportation corridors, and rural contributions. 

6.      Enforce stringent erosion and sediment controls for construction and infrastructure maintenance activities.

7.      Protect and restore natural streams and stream processes by managing runoff and sediment loss at source, and protecting valley and stream corridors, and naturalizing altered streams.

8.      Remove and/or mitigate human-built barriers to fish passage and sediment transport, including on-line ponds, where recommended by the Fisheries Management Plan.

9.      Maintain self-sustaining, resident/migratory fish and wildlife populations as barometers of a healthy natural heritage system.

10.  Identify and raise awareness of past and present human influences on the watersheds and the strong link between human heritage, watershed recreation and human and environmental health.

Technical studies were prepared in support of the Duffins Watershed Plan

The following technical studies in support of the Watershed Plan were undertaken:

·        Surface Water Quality and Quantity;

·        Groundwater Quality and Quantity;

·        Aquatic Habitat and Species;

·        Terrestrial Habitat and Species;

·        Human Heritage; and,

·        Public Use – Outdoor Recreation.

 

            COMMENT
Only a small portion of the Duffins Creek watershed lies within the Town of Markham.  The portion that is contained in Markham is not within the urban boundary.  Current land use in the Duffins watershed area in Markham is predominantly agricultural.  Furthermore, these lands comprise a portion of the federally owned Airport Lands. 

 

            The Oak Ridges Moraine Conservation Plan (ORMCP) identifies the minimum standards that must be addressed in watershed plans for headwaters on the Oak Ridges Moraine.  Although, the Duffins and Carruthers Watershed strategy planning process commenced prior to the Oak Ridges Moraine legislation, the majority of the minimum standards outlined in the ORMCP have been addressed in the final draft of the Watershed Plan.  However, pending Provincial Technical Guidelines may require additional information or recommend methodologies in addition to those already addressed. The Watershed Plan will also need to reflect Provincial requirements for source water protection, once finalized by the Province.   As such, Council should endorse the Watershed Plan, in principle, to allow for any modifications that may result from required provincial technical requirements. 

 

            The strategic directions endorsed by Council arising from the Eastern Markham Strategic Review support the goal and objectives for the Duffins Creek Watershed Plan (i.e. protection of rural countryside in Eastern Markham) .  The Town will be undertaking a review of its environmental policies in the rural area in 2004 and will consider the implementation strategies in the Watershed Plan as input into the review process.

 

            IMPLEMENTATION

The details of how the proposed Watershed Plan will be implemented have not yet been finalized.  The Toronto and Region Conservation Authority will be consulting with affected municipalities in the fall 2003 to determine an appropriate model for the long-term implementation of the Watershed Plan and any budget considerations.  To ensure that the Town’s interests are considered, it is recommended that the Town continue to work closely with the TRCA is developing an appropriate model. 

 

FINANCIAL CONSIDERATIONS

The Town has already contributed $5,000 towards the preparation of the Watershed Plan.  There has been no request for additional funding at this time.    

 

ENVIRONMENTAL CONSIDERATIONS

The Watershed Plan for the Duffins and Carruthers Creek was developed as an action-oriented Watershed Plan with a focus on partnership implementation.  Given the significant land holdings by the Provincial and Federal governments, the Watershed Plan acknowledges innovative management opportunities.  The Watershed Plan supports the Town’s emerging priorities for protection of the Town’s rural lands. 

 

ENGAGE 21st CONSIDERATIONS

The Watershed Plan for Duffins Creek and Carruther Creek aligns with the Environmental Focus goal of the Town’s Engage 21st Markham Strategic Plan. 

 

BUSINESS UNITS CONSULTED AND AFFECTED

The Engineering Department has participated in the watershed study process and reviewed this report.   


 

CONCLUSION

The Duffins Creek Task Force and the Toronto and Region Conservation Authority are to be commended for the progress made in the preparation of the Watershed Plan.  The document provides a strong basis for protection of the watershed and offers an integrated management approach.  Staff recommend the Town endorsed the Watershed Plan for the Duffins Creek and Carruthers Creek and continue to work cooperatively with the Toronto and Region Conservation Authority in the implementation of the Watershed Plan.
