Grant Murphy, P.Eng., Director of Engineering Services PREPARED BY: Jeff Prince, P. Eng., Design and Construction Engineer WARD(S) INVOLVED: Ward 3 DATE OF REPORT: September 7, 2009 REPORT NO.: DTS 09-134 SUBJECT: CONESTOGA COLLEGE/BLAIR INDUSTRIAL LANDS SANITARY SERVICING EA -CITY OF CAMBRIDGE RECOMMENDATIONS: THAT the Conestoga College South Campus and Blair Business Park Sanitary Servicing Class Environmental Assessment Study Report prepared by MTE Consultants Inc., dated August 2009 be endorsed by Council; AND THAT Council directs staff to prepare a cross border servicing agreement with the City of Cambridge to outline; operational and maintenance requirements, easement requirements and the sewage rate charge for the flows being conveyed to and treated at the Kitchener Wastewater Treatment Plant. EXECUTIVE SUMMARY: The City of Cambridge has completed a Class Environmental Assessment study to identify the preferred means of providing sanitary service for Conestoga College's South Campus and the Blair Business Park to the Kitchener Wastewater Treatment Plant, including a location for a new sewage pumping station (in Cambridge), and the preferred route for a sewage outlet from this new pumping station to the Treatment Plant. In May 2009, Council directed City of Kitchener staff to participate in the Class Environmental Assessment (Class EA) and report back. It should be noted that for this project, sanitary sewage will be generated in the City of Cambridge, flow through the City of Kitchener and be treated in the Regional Wastewater Treatment Facility, located in Kitchener. The study outcome required careful review and discussion with all parties throughout the Class EA process. The preferred alternative, as shown on Figure 12.0 (attached), includes the location of a gravity sewer system from the Blair Business Park to a Sanitary Pumping Station, located at the northwest corner of Fountain Street and Morningside Drive (City of Cambridge), and a sanitary 3-1 forcemain routing down Morningside Drive crossing Highway 401, then crossing the Conestoga (boon) North Campus, continuing along Doon Valley Drive and Old Mill Road to the trail along the Grand River and ultimately outletting to the Kitchener Wastewater Treatment Facility. The selection of the preferred alternative was based on an evaluation of the natural, economic and social conditions as well as public health and safety concerns as they apply to the proposed work. BACKGROUND: In May 2009, City Council directed staff to participate in the Class EA process and report back the results of the study. The City of Cambridge initiated the Schedule "B" Class Environmental Assessment (EA) Study to identify a sanitary sewage servicing solution for the Blair Business Park and the Conestoga College South Campus, both sites located near Fountain Street and Highway 401, in the City of Cambridge. The requirement for this study was identified as a condition of the Region of Waterloo's Official Plan Amendment No. 24 wherein it states that the lands identified may only be developed upon completion and approval of "an Environmental Assessment to identify the appropriate method of sanitary service from a municipal sewage treatment plant." MTE Consultants Inc. was subsequently retained by the City of Cambridge to complete the Schedule "B" Class EA Study by evaluating a range of alternatives and, through this process, ultimately selecting the Preferred Alternative. The Blair Business Park is 30.4 ha in size and is generally bounded by Highway 401 to the west, Fountain Street to the north, Dickie Settlement Road to the east, and Old Mill Road to the south. The proposed Conestoga College South Campus is 53.1 ha in size and is generally bounded by Highway 401 to the west and north, Morningside Drive to the east, and Fountain Street to the south. Both properties are located within the City of Cambridge municipal boundary, are included in the Region's Official Plan designation for business school usage, and are identified in the Region's Sanitary Master Plan for servicing by the Kitchener Waste Water Treatment Plant. The scope of this EA Servicing Study includes the collection and identification of the constraints and opportunities within the study area for evaluation by the project team. Utilizing this information, the project team developed alternative solutions for the servicing of these lands. All solutions were then evaluated in a manner consistent with the Class Environmental Assessment process for Schedule "B" projects, with the primary objective to identify a "Preferred Sanitary Sewage Servicing Solution" for the Blair Business Park and the Proposed Conestoga College South Campus. REPORT: The Conestoga College South Campus and Blair Business Park Sanitary Sewer Servicing Class EA Study makes the following recommendations: • The Blair Business Park will be serviced by a gravity sewer routed across Fountain Street, then easterly within the north shoulder of Fountain Street to the proposed new Blair Pumping Station at the northwest corner of Morningside Drive and Fountain Street; 3-2 • The installation of this gravity sanitary sewer for the Blair Business Park should be included as part of the intersection improvements required for the Conestoga College South Campus access road; • Anew Blair Sanitary Sewage Pumping Station will be located at the northwest corner of Fountain Street and Morningside Drive on land currently owned by Conestoga College that will deeded to the City of Cambridge; • Twin 300 mm diameter discharge forcemain will be required from the new Blair Sanitary Pumping Station in the City of Cambridge to the Kitchener Wastewater Treatment Plant (WWTP); • The discharge forcemain will exit the pumping station and continue northerly along Morningside Drive (in the west driving lane) to a crossing location of Highway #401 west of the existing pedestrian bridge; • The crossing method will utilize trenchless installation technologies, the exact method of which shall be determined during final design once more detailed and current geotechnical conditions of the crossing area are fully known; • Consideration should be made during the final design process to ensure all opportunities are considered to maximize usage of the infrastructure pipe crossing of Highway #401; • After crossing Highway #401, the forcemain will traverse northerly across Conestoga College Doon Campus parking lots and then westerly along Doon Valley Drive to Old Mill Road. The forcemain will continue along Old Mill Road to the existing Old Mill Pumping Station property where it will leave the municipal road right-of-way. The forcemain will then follow the alignment of the existing sanitary forcemain which runs alongside the Grand River, crossing Schneider Creek and following an existing pathway to the Kitchener WWTP, where it will ultimately discharge into the existing raised gravity sewer system; • Municipal consent/Agency approvals of the final alignment is required at the final design stage; • Property requirements/easements to be confirmed during final design include: • Property will be required from Conestoga College for the Pumping Station Site Plan footprint located at the northwest corner of Fountain Street and Morningside Drive. The site area is approximately 0.3 ha (0.74 acres); and, • Forcemain easements will be required through: the Conestoga College South Campus near Highway #401; the Conestoga College Doon Campus parking lots; and, the open space area between Old Mill Road and the Kitchener WWTP, which includes lands owned by the City of Kitchener and the Region of Waterloo. • That an agreement be prepared between the City of Cambridge and City of Kitchener to outline: operational and maintenance requirements; any easemenbencroachment requirements; and, the cross-border sewer rate charge for the flow from Cambridge into Kitchener; and, 3-3 The City of Cambridge will make arrangements to facilitate a public open house meeting with the affected property owners to present the detailed design and construction staging. The open house meeting should be scheduled a minimum of two weeks prior to the commencement of construction. FINANCIAL IMPLICATIONS: The EA study and subsequent implementation works are being funded entirely through the City of Cambridge. The City of Cambridge will also pay all of the City of Kitchener staff costs associated with the Class EA and the design and construction phases of the project. COMMUNICATIONS: To guide the decision making process for this Class EA Study, a Technical Steering Committee (TSC) was assembled consisting of representatives from the City of Cambridge, the City of Kitchener, MTO, GRCA, Region of Waterloo and the Owners as identified further in this report. Formal TSC meetings were held throughout the duration of the study to access pertinent data in addition to various sanitary servicing strategies, public /agency input, property owner comments and public open house materials. A formal "Notice of Intent" was published in the Waterloo Region Record and Cambridge Times newspapers during the week of June 12, 2009 to invite public review and comment on the identification of a sanitary sewage servicing solution. Presentation material and drawings were made available at Public Information Centre #1 held at Conestoga College, Doon Campus on June 23, 2009. Public Information Centre #2 was again held at Conestoga College on August 27, 2009, to present the "Preferred Alternative". In addition to again being advertized in the Waterloo Region Record and Cambridge Times, notices for the Public Information Centre were hand delivered to the residents along the preferred route. Feedback received from the Public was incorporated into the final selection where possible. Based on an evaluation of natural and social environment concerns, economic analysis, as well as public health and safety concerns, it was confirmed that the final "Preferred Alternative" was approved by the Technical Steering Committee. During the consultation process, several key issues were identified as being significant in the decision making process. Comments received were considered by the project team and implemented where appropriate. All correspondence and subsequent responses are documented in the Final Environmental Study Report (ESR). CONCLUSIONS: The completion of the Conestoga College South Campus and Blair Business Park Sanitary Servicing Class Environmental Assessment Study has established a preferred alternative to provide sanitary services to the subject lands. The preferred alternative, as shown on Figure 12.0 (attached), includes the location of a gravity sewer system from the Blair Business Park to a Sanitary Pumping Station, located at the northwest corner of Fountain Street and Morningside Drive (City of Cambridge), and a sanitary forcemain routing down Morningside Drive crossing Highway 401, then crossing the Conestoga 3-4 (boon) North Campus, continuing along Doon Valley Drive and Old Mill Road to the trail along the Grand River and ultimately outletting to the Kitchener Wastewater Treatment Facility. The ESR Document has been completed in accordance with the Environmental Assessment Act and following endorsement by the City of Kitchener, the City of Cambridge Council will complete its final review and approval. The EA Document will then be placed on record for the 30 day mandatory period. ACKNOWLEDGED BY: Jeff Willmer General Manager, Development and Technical Services 3-5 3-6
