1 Request for Proposal For Engineering Services to Assess Foster Avenue Retrofit Stormwater Management Facility In the Municipality of Belleville Requested by Quinte Conservation Authority November 8, 2017 RFP Contact: Mark Boone Closing: Wednesday, November 29, 2017 at 3:00 pm Quinte Conservation RR# Old Highway 2 Belleville, ON K8N 4Z2

2 Introduction Quinte Conservation is completing an Environmental Assessment (EA) to assess options for retrofit treatment of stormwater from the Foster Ave catchment area in the City of Belleville. The outfall for this drainage area was identified in the City of Belleville Pollution Control Plan as a source of contamination to the Bay of Quinte. The City of Belleville and Quinte Conservation are working together to complete an EA for finding a solution to reduce the amount of pollutant loading to the Bay. To assist in this project Quinte Conservation is seeking the support of an engineering consultant to help with the engineering component. The main components of the Study will include: 1.) Assessment of the stormwater catchment area to determine potential options for the retrofit treatment of stormwater runoff, 2.) Completion of a Municipal Class Environmental Assessment, Schedule B for the selection of an appropriate remedial solution for the treatment of stormwater runoff, 3.) Detailed engineering drawings of the preferred solution with associated design brief, Quinte Conservation and the City will be undertaking the main components of the Environmental Assessment, however engineering support will be required to assist in determining potential treatment options and assessing the feasibility of these options. Background In 1985, the International Joint Commission under the Great Lakes Water Quality Agreement designated the Bay of Quinte as an Area of Concern due to degradation of the water quality. The Bay of Quinte Remedial Action Plan (BQRAP) was established to restore the beneficial uses of the Bay of Quinte. A total of 80 recommendations were identified in the Bay of Quinte Restoration Council, Stage II - Time to Act document as actions to be taken by various agencies and municipalities to improve the water quality. Recommendation #23 of the Stage II report required completion of Pollution Prevention and Control Plans (PPCPs) for Belleville, Trenton, Picton and Deseronto. Pollution Prevention and Control Plans (PPCP) have been developed for the bay front municipalities that provide guidance on continuing efforts to reduce pollution from urban areas. The latest regional PPCP completed in 2011 notes that more effort can be placed on stormwater end of pipe remedial measures for existing built-up areas. In order to assist in the de-listing of the Remedial Action Plan area, Quinte Conservation received funding from the Great Lakes Sustainability Fund and the Canada-Ontario Agreement for the Great Lakes (approval pending) to reduce the impacts of urban stormwater runoff on the water quality in the Bay of Quinte. This is to be achieved by providing project management services to the City of Belleville, Quinte West, Prince Edward County and other local municipalities for the design, approvals and construction of remedial stormwater management facilities in existing, built-up urban areas as identified in the Pollution Prevention and Control Plans completed in 1997, 1998 and 2011 respectfully.

3 The Bay of Quinte Remedial Action Plan has identified stormwater as a significant source of pollutants to the Bay of Quinte. Many actions have been taken by the BQRAP and municipalities to reduce stormwater impacts on the Bay including removal of cross-connections, pet litter control, reduction of sanitary bypasses, street sweeping, and stormwater control of new urban areas. However, many outfalls still drain untreated stormwater into the Bay and are a significant source of phosphorus contamination. Within the eastern portion of the City of Belleville one such outfall exists, called the Foster Ave Catchment, draining a 120 hectare area; (see Figure 1) Figure 1: Foster Ave Catchment Area

4 Objective The objective of the project is to determine a solution for improving the quality of stormwater draining from the Foster Ave catchment into the Bay of Quinte. Scope of Work In view of current funding the scope of work has been identified below and is to be completed in two phases. Phase 1 1. Review of existing information including storm sewer mapping of the catchment, 2. Field verification of any uncertainties in the storm sewer mapping, 3. Review of the hydrology of the catchment area for assistance in determining appropriate solutions for water quality treatment, 4. Assist Quinte Conservation in the assessment of potential options in managing stormwater quality. This review may include a review of conventional, LID, and other technologies for treating stormwater. Options are to be chosen in reference to the following: Acceptable Engineering Standards, Quinte Conservation Stormwater Management Guidelines (2012), Bay of Quinte Rap Stormwater Guidelines (2006), Low Impact Development Stormwater Management Planning and Design Guide (2010, Credit Valley and Toronto Region Conservation Authority). Stormwater Management Planning and Design Guide, Ministry of the Environment - March, Preparation of a conceptual design of potential stormwater treatment options along with associated design brief, 6. Preparation of informal progress reports and provide input as needed to assist in preparation for Public Information Centres (the open houses are to be coordinated by Quinte Conservation). Phase 2 1. Preparation of detailed design of the preferred option suitable for submission to the MOECC for an Environmental Compliance Approval, 2. Preparation of a design brief to accompany the detailed design, Available Data Quinte Conservation will provide available documentation pertinent to the study. To this end we have the following information which may be of use: Mapping of the storm sewer system as provided by the City of Belleville,

5 Project Screening Brief South Foster Avenue Stormwater Management Facility Prepared by Sernas Associates for the City of Belleville. Including output from Hydrologic Model SWMHYMO-99 as prepared by the Sernas group dated February 3, GIS data: o 2008 & 2013 air photos o soils o floodlines ( 1: 100 year) o flood polygon (100 year) o 5m contours o Digital Elevation Model o buildings (point & poly) o Ontario land cover compilation o LiDAR Study Deliverables Reports, charts, tables, spreadsheets and other documents are to be provided in Microsoft Office format and in Adobe Acrobat portable document format (.pdf). A digital copy of any hydrologic modelling is to be provided to Quinte Conservation. Any maps or engineering drawings are to be provided in hard copy and electronically in AutoCAD and Adobe Acrobat portable document format (pdf). Meetings Meetings shall be held with QC at key points throughout the study. A start-up meeting will be required to confirm the study methodology, schedule, etc. One or more meetings may be required to discuss potential options and evaluate the feasibility of these options. All meetings will be at a mutually agreed location (i.e. at the conservation authority office, onsite or at the consultant's office). Consultants Qualifications Consultants shall be licensed by the Professional Engineers of Ontario and have a consulting designation. The consultant shall demonstrate relevant experience in the design of stormwater management facilities (with a focus on quality). The consultant must demonstrate proof of adequate insurance (public liability and professional errors and omissions) as well as WSIB clearance.
