5 TO: FROM: Chair and Members of the Executive Committee Meeting #9/11, October 14, 2011 Adele Freeman, Director, Watershed Management Item EX8.3 RE: NAMING OF TORONTO AND REGION CONSERVATION AUTHORITY ASSET Pedestrian Bridge in Boyd Conservation Area KEY ISSUE Approval to name a pedestrian bridge in honour of the Huron-Wendat First Nations in Boyd Conservation Area. RECOMMENDATION THAT one existing pedestrian bridge located on Toronto and Region Conservation Authority (TRCA) land known as Boyd North in Woodbridge, City of Vaughan be given the First Nations name of "Sarenhes Bridge" in honour of the Huron-Wendat Nation's ancestral ties to the area; AND FURTHER THAT Friends of Boyd Park, Humber Watershed Alliance and the City of Vaughan be so advised. BACKGROUND TRCA and the City of Vaughan have constructed a multi-use trail that follows the Humber valley from Kleinburg to Boyd Conservation Area. Several pedestrian bridges have also been installed as part of the trail system. Humber Watershed Alliance members, Friends of Boyd Park and other residents have long advocated that the history of the area and points of interest be promoted along the trail using interpretive signs and the naming of the pedestrian bridges. First Nations Peoples lived in the Humber River valley following the retreat of the Laurentide Ice Sheet. PaleoIndian People (12,000-10,000 years B.P.) would have been the first inhabitants, followed by "People of the Archaic Period" (10,000 to 2,800 B.P.) and those of the "Woodland Period" (circa B.C A.D.1650). A large village community of the Huron-Wendat People once lived on the property now known as Boyd North in Woodbridge. Evidence of longhouses have been discovered from the Late Woodland Period (circa A.D ). The villagers would have used the fertile flood plain beside the river for growing crops of corn, squash and beans. The river also provided them clean drinking water and fish. In honour of the significant ancestral tie to this area, TRCA staff proposes that one pedestrian bridge in the vicinity of a well known archaeological site be dedicated to the First Nations Peoples who were the first human inhabitants of this valley. Decedants of the Huron-Wendat who now live in Quebec were asked to suggest a name for one pedestrian bridge. The name "Sarenhes" was suggested. It is the Huron-Wendat word meaning "The tall tree". TRCA archaeological staff, Vaughan staff, Friends of Boyd Park and members of the Humber Watershed Alliance agree with the suggested First Nations name. 189

6 Naming of TRCA assets requires Authority approval, but staff is requesting the approval of the Executive Committee rather than the Authority due to time sensitivity as a public nature hike including an informal sign unveiling ceremony has been proposed by community members for October 16, DETAILS OF WORK TO BE DONE Upon approval, the sign will be created and installed adjacent to the pedestrian bridge in Boyd North just north of Rutherford Road, in close proximity to the regionally significant Seed-Barker archaeological site. It has also been suggested that this well known archaeological site be renamed to reflect its Huron-Wendat heritage. This matter will be further investigated by TRCA staff before bringing a report to the Authority. A small informal unveiling ceremony will be hosted on October 16, 2011 in partnership with representatives of the Huron-Wendat Nation, City of Vaughan, TRCA and members of the community. FINANCIAL DETAILS The estimated $1,500 funds for the sign are available in the York Region capital budget in TRCA's East Humber Community Enhancement Projects account Report prepared by: Susan Robertson, extension s: srobertson@trca.on.ca For Information contact: Susan Robertson, extension s: srobertson@trca.on.ca Date: October 4, 2011 Attachments: 1 190

The purpose is to facilitate the construction of Prince Regent Street, in the Cathedral Community, including the placement of granular material, curbs and asphalt, over top of an existing culvert. The permit will be issued for the period of October 14, 2011 to October 13, 2013 in accordance with the following documents and plans which form part of this permit: Letter of undertaking provided by Pascal Monat of Cole Engineering on behalf of Monarch Corporation and The Crown of Markham Inc, dated October 5, 2011, to address all outstanding TRCA issues prior to the issuance of the permit; RATIONALE The application was reviewed by staff on the basis of the following information: 198

15 Proposal: The subject property is located between Highway 404 and Woodbine Avenue, north of Major Mackenzie Drive in the West Cathedral Community, Town of Markham. In accordance with the West Cathedral Secondary Plan and Master and Environmental Servicing Plan, the portion of East Carleton Creek that traverses the plan area was realigned and restored - a TRCA permit for which was issued June 2008 (and expired in June 2010). The original permit included the restoration of East Carlton Creek which involved the widening of the valley corridor, the realignment of the entire watercourse within the West Cathedral community based upon natural channel design principles, and the installation of a culvert to provide an overpass for a future road connection. These restoration and infrastructure works are now complete, however the final grading of the future road located adjacent to East Carleton Creek, as well as the completion of the road across the top of the culvert, remains outstanding. This permit is to complete the construction of Prince Regent Street, which crosses the enhanced East Carleton Creek corridor. The works include the installation of erosion and sediment controls along East Carlton Creek, the placement of granular material, curbs and base and top coat of asphalt, within the area in which the road is to be constructed. The drawings provided are consistent with the engineering drawings approved by the Town of Markham. Control of Flooding: The proposed realignment of the corridor has been completed to contain Regional Storm flows, as such, there are no storage or conveyance of flood waters associated with this permit. Pollution: Appropriate Sediment and Erosion control measures will be put in place and maintained during all construction phases. Dynamic Beaches: Not applicable Erosion: Sediment and erosion control measures will remain in place throughout the construction phases. There are no geotechnical concerns associated with this proposal. Conservation of Land: Landscape and enhancement plans, which met TRCA s requirements, were implemented a part of the previous permit.

17 RATIONALE The application was reviewed by staff on the basis of the following information: Proposal: The proposal involves construction of an approximately 18m extension of the existing 8.5m x 2m box culvert located 110m east of Frontenac Drive under Highway 7, construction of two new storm drain outlets (450mm and 375mm diameter), replacement of an existing 600mm pipe outlet and headwall including the installation of an oil grit separator, improvements to the roadside drainage ditches along the north and south sides of Highway 7, and raising the existing retaining wall on the south side of Highway 7 to match the proposed sidewalk, in a Regulated Area of the Rouge River Watershed, in the Town of Markham, Regional Municipality of York. The work is being undertaken to support the widening of Highway 7 to accommodate new rapid transit lanes as part of VIVA's H3 expansion project. In addition to the widening, water quality enhancements have been proposed in order to provide additional treatment of road drainage and improve the existing storm water system. Control of Flooding: The project is located within the Regional Storm Flood Plain. The proposed work will have minimal impacts to the existing grades and configuration of the current stormwater conveyance scheme, and is therefore not anticipated to negatively affect the conveyance or storage of flood waters. Pollution: Standard erosion and sediment control measures (sediment control fence and coffer dams) will be implemented prior to construction, maintained for the duration, and removed only after the site is stabilized and restored. Erosion and sediment control measures have been provided in accordance with the TRCA Erosion and Sediment Control Guidelines for Urban Construction. Dynamic Beaches: Not applicable Erosion: No geotechnical/slope stability issues have been identified for the proposal. Conservation of Land: The work and access areas will be isolated from the creek with sediment and erosion control fencing and all in-water/channel works will be isolated with coffer dams and a bypass pumping system. With the proposed erosion and sedimentation control plans in effect, the potential for a harmful alteration, disruption or destruction (HADD) of fish habitat will be mitigated, and a Letter of Advice will be written by TRCA staff on behalf of Fisheries and Oceans Canada (DFO). The MNR warm water fisheries timing window (construction to occur between July 1 and March 31) will apply to the works. The proposed storm water works are anticipated to improve water quality and result in a net ecological gain to the receiving watercourse. Plantings The area will be planted with a native seed mix and live stakes to restore and stabilize the disturbed areas. 201

18 Policy Guidelines: This proposal is consistent with Section Infrastructure and Servicing - of the Toronto and Region Conservation Authority's Valley and Stream Corridor Management Program. CFN: Application #: 0278/09/MARK Report Prepared by: Brian Storozinski, extension 5744 For information contact: Brian Storozinski, extension 5744 Date: October 12, 2011 EX REGIONAL MUNICIPALITY OF YORK To construct, reconstruct, erect or place a building or structure, site grade and temporarily or permanently place, dump or remove any material, originating on the site or elsewhere at Bob Hunter Memorial Park (7218 Reesor Road), in the Town of Markham, Rouge River Watershed as located on the property owned by the Toronto and Region Conservation Authority. The purpose is to permit the replacement of the existing Tanglewood Pedestrian Bridge located in Bob Hunter Memorial Park. A Letter of Advice will be written by TRCA staff on behalf of Fisheries and Oceans Canada (DFO). The Ministry of Natural Resources (MNR) warm water fisheries timing window will apply to the works. The permit will be issued for the period of October 14, 2011 to October 13, 2013 in accordance with the following documents and plans which form part of this permit: Letter of Undertaking prepared by the Regional Municipality of York, dated October 11, 2011, received by TRCA on October 12, RATIONALE The application was reviewed by staff on the basis of the following information: 202

19 Proposal: The proposal involves the replacement of the existing Tanglewood Pedestrian Bridge located in Bob Hunter Memorial Park, north of Steeles Avenue East, west of Reesor Road, within a Regulated Area of the Rouge River Watershed, in the Town of Markham. The Tanglewood Bridge replacement is being done as part of the Southeast Collector Enhancements and in accordance with the Bob Hunter Memorial Park Enhancement Plan. This project is being undertaken by York Region as part of their Bob Hunter Memorial Park Enhancement Plan, and relates to Condition 13 of the Ministry of Environment's conditions of approval for the Southeast Collector Trunk Sewer Project. The work will include: removal of the east abutment and installation of an armourstone/boulder wall on the south side of the west abutment to buttress the existing gravel/stone wall. The bridge foundation will be installed using a drilled caisson method, and new abutments will be installed further from the creek using cast in place pile caps. The bridge will be assembled and placed on the abutments to minimize the amount of construction taking place above the watercourse. Control of Flooding: The project is located within the Regional Storm Flood Plain. The proposed construction will increase the height of the bridge over the watercourse and provide additional clearance for flood waters, and grading works will cut the existing slope to achieve a more gradual, stable grade. The works are not anticipated to negatively affect the conveyance or storage of flood waters. Pollution: Standard erosion and sediment control measures (sediment control fence and metre bags) will be implemented prior to construction, maintained for the duration, and removed only after the site is stabilized and restored. Erosion and sediment control measures have been provided in accordance with the TRCA Erosion and Sediment Control Guidelines for Urban Construction. Dynamic Beaches: Not applicable Erosion: The eastern bridge abutment will be removed and the slope will be altered to achieve a 3:1 slope gradient in order to mitigate erosion concerns. The proposed design represents an improvement to the existing conditions as it relates to slope stability and erosion protection. Conservation of Land: The work and access areas will be isolated from the creek with sediment and erosion control fencing and grading and abutment locations will be isolated with coffer dams. With the proposed erosion and sedimentation control plans in effect, the potential for a harmful alteration, disruption or destruction (HADD) of fish habitat will be mitigated and a Letter of Advice will be written by TRCA staff on behalf of Fisheries and Oceans Canada (DFO). The MNR warm water fisheries timing window (construction to occur between July 1 and March 31) will apply to the works. Seven trees will be removed to accommodate access construction and equipment access. Plantings The Region has proposed the planting of 3 trees, 29 shrubs, and numerous live stakes to restore the area and provide slope stabilization. 203

20 Policy Guidelines: This proposal is consistent with Section Development and Redevelopment Intensification Within Non Established Communities Highly Urbanized Areas - of the Toronto and Region Conservation Authority's Valley and Stream Corridor Management Program.
