A The facility is designed to control the post development storm water rates of flow to the predevelopment (existing) conditions for storm events up to the 1 in 100 year storm event, while not exceeding the downstream floodlines and flow depths . Q WILL THE FACILITY AND CHANNEL BE ON PUBLIC PROPERTY AND WHO WILL MAINTAIN IT? A The facility and channel will be built on lands owned by or controlled by the Town of Newcastle. The Channel passes through some privately owned lands on which easements have been obtained. The land owned by one private owner, who has not granted an easement, will not be disturbed. The Town of Newcastle will maintain the facility and channel when it is completed. Q WHO WILL PAY FOR THE PROPOSED CONSTRUCTION? A The facility and channel will be 100% paid by the developers benefiting from the works . Q ARE GOVERNMENT APPROVALS IN PLACE FOR THE WORK? A Yes, approvals have been received from all necessary agencies including: • the Central Lake Ontario Conservation Authority (C.L.O.C.A. ) ; • the Ministry of the Environment (now the MOEE) ; • the Ministry of Natural Resources (MNR) ; • the Northumberland-Newcastle School Board. Approvals are anticipated soon from the Town of Newcastle. Construction will not proceed until these are obtained. ATTACHMENT N0. 3 WD-21-93 i Q HOW DOES THE FACILITY WORK? Q The facility comprises a 2-cell stormwater management and water quality facility with a lined outfall channel . The upstream cell is designed to facilitate the collection of sediment. The cell will be drained by a perforated pipe which will outlet downstream of the second cell. This pipe is designed to promote infiltration and hence 1groundwater recharge. For storms greater than a 2 year event, the upstream cell will overtop the berm and storm water will be controlled by the downstream berm. The combination of both cells will provide storm water control up to the 100 year event. Flows in excess of this event are designed to overtop the berm. The downstream channel is designed to convey flows up to the 2-year storm. Flows in excess of this storm will overtop the channel . Floodlines under existing conditions are not exceeded under post development conditions . Q WILL ANY EXISTING TREES HAVE TO BE REMOVED? A Special attention has been made to maximize the retention of the existing trees . The downstream channel has been designed to meander around existing trees . Only the trees in the area of the downstream berm will be removed to construct the berm. Q WHAT ENVIRONMENTAL CONSIDERATIONS HAVE BEEN INCLUDED? A The facility is also designed to protect the sensitive cold water fisheries downstream in the Soper Creek. This has been achieved by promoting sediments to settle out in the upstream cell. Also, the protection of the existing tree cover, and the planting of new trees, will provide shading of the channel which minimizes warming and hence facilitates the protection of the coldwater fisheries. Special attention will be made during construction to minimize sediments being carried downstream while the ground is disturbed. The incidence of flooding of the existing trees in the downstream cell has been minimized by the construction of the upstream berm. m:\magowan\factshee.m17 I c Marshall 80 COMMERCE VALLEY DR.

Dear Sir, RE: Comments Received at Information Centre, March 2A, 1993 Stormwater Management Facility and Channelization West Branch of Soper Creek As a follow up to our March 24, 1993 Information Centre concerning the proposed SWM Facility and Channelization for the West Branch of Soper Creek, we have summarized the concerns and comments of residents who attended the meeting. We have attached copies of the sign-in sheet from the meeting and the Question and Answer Fact Sheet which was provided to all attendees. In general, we feel that the display was well received by the attendees and that many of their concerns were sufficiently addressed in discussions with yourself and us. A total of 18 people signed the sign-in sheet, while approximately 5 additional people attended without signing in. Specific concerns/comments and how they have been or will be addressed follow: 1. Comment: Praise for the quality of the drawings and the display, but scepticism from a few people as to whether the drawings were too slick and might therefore shield what was "really" happening. Resolution: The drawings were prepared for the presentation to make them look less "engineered" and to provide a realistic picture of what the facility will look like after construction is completed. 2. Comment: Why had some residents not heard of the project previously? Resolution: The facility and channel were supposed to have been constructed prior to many of the newer developments being constructed. Residents along King Street were notified in 1989 of the facility and an Information Meeting was held with them at that time. Unfortunately, the facility was delayed in the approval process by CLOCA, MNR and MOE. Since the design concept was only recently approved by all the authorities, it would have been premature to notify residents again without an approved design. ATTACHMENT N0. 4 WD-21-93 kCCLLCNG INA 3. Concern: Why is Schickedanz Brothers Limited leading the project? Resolution: Since Schickedanz Brothers Limited were one of the larger upstream developers to commence construction, the Town requested that they assume responsibility for the design and construction of the SWM Facility and Channelization construction. The cost of construction will be shared by all benefitting developments and will be subject to a Front Ending Agreement with the Town. 4. Concern: Is the SWM Facility really needed? Resolution: The facility is required to control the quality and quantity of water which will discharge from the west branch of Soper Creek to the main branch of Soper Creek. 5. Concern: Is this a watershed solution or just a solution for future development? Resolution: The facility is designed as a watershed solution. The facility will provide qualitylquantity control for both existing and new development. It was pointed out to several homeowners that the facility actually serves their homes as well. 6. Concern: Is runoff from other drainage areas being diverted into this facility? Resolution: The existing pre-development drainage boundaries will be maintained and therefore, no runoff from adjacent drainage areas will be diverted into this facility. 7. Concern: Will the flooding of areas downstream of the facility be increased/decreased after construction? Resolution: The facility is designed to maintain existing floodlines to pre-development levels as set by CLOCA. Residents were reminded that the floodplain area downstream of the facility will therefore, continue to flood after construction. 8. Concern: Is there any chance the project will not proceed? Resolution: Approvals have been received from MNR, MOE and CLOCA. The facility is required now to address existing water qualitylquantity concerns in addition to the future concerns, The facility has the full support of the Town. i% t/J INA 9. Concern: The construction of the south berm will require some trees to be cut down. Resolution: While it will be necessary to remove some trees to construct the south berm, a tree and shrub planting program will be undertaken to replace the removed trees. 10. Concern: Trees will be cut down as a result of the channel construction. Resolution: While questions about the status of specific trees could not be addressed at the meeting,residents were assured that the proposed channel alignment was selected to minimize and where possible, eliminate the removal of trees. 11. Comment: The area where the proposed facility will be located needs to be "cleaned up" anyway. Resolution: Construction impact in the south cell will be minimal. Post-construction seeding, tree and shrub planting, and pedestrian access will enhance the aesthetics of the north cell. I 12. Concern: Will there be pedestrian access to the area? Resolution: The existing and proposed developments adjacent to the facility have been designed to include the potential for pedestrian access through the area. The final location of walkways within the facility will be approved by the Town Parks Department. 13. Concern: There is flooding currently occurring at the newly constructed footbridge immediately south of the proposed facility. Resolution: The channel invert elevation will be lowered greater than 0.60m at this location. The footbridge has been constructed to match the proposed elevations of the channel. I 14. Comment: A wet pond solution would have been better. Resolution: Given the storage requirements and the concerns over liability with respect to a wet pond, this option was considered impractical for this application. I i 1/ / 15. Concern: One Peachtree Crescent resident was concerned that a fence would be constructed around the pond which would therefore impact their view. Resolution: A fence is recommended to limit pedestrian access to the facility. 16. Concern: The low flow channel in the south will be dry. Resolution: Under low flow conditions, runoff will be piped underground from the north berm to south of the south berm to promote the cooling of the water and groundwater recharge (if any). 17. Concern: Mr.Nimigon still believes a piped solution across his property is the best solution. Resolution: Mr.Nimigon was informed that the MNR and CLOCA have rejected this option. 18. Concern: Some residents expressed concern that the channel would not be constructed across the Nimigon property. Resolution: Since Mr. Nimigon has not agreed to an easement across his property, the Town cannot construct or maintain the channel in this section. However,funds will be included in the cost sharing to cover a future easement and channel construction. 19. Concern: One Highway#2 resident was concerned that the bridge that is to be constructed over the channel at the back of her property as part of her agreement to grant the easement would be forgotten. Resolution: The proposed bridge will be shown on the landscape plans and constructed as part of the landscaping contract. 20. Concerns: Construction scheduling, noise, dust, etc... Resolution: Residents were informed that construction within the existing creek bed can only occur between June 15 - September 15 (MNR's window), however, construction outside the creek bed may continue beyond September 15. Noise and dust will be mitigated as best as possible. Anticipated disruptions will be those normally associated with construction sites. i Aft 21. Concerns: The cost of maintaining the facility. Resolution: Maintenance will be the responsibility of the Town. The facility is designed to minimize maintenance operations, and therefore, cost. We trust this summation accurately reflects the comments/concerns we received at the meeting and our responses to these concerns.
