Phase One Environmental Site Assessment 296 Somerset Street East, Ottawa, On Executive Summary PHASE ONE ENVIRONMENTAL SITE ASSESSMENT 296 SOMERSET STREET EAST, OTTAWA, ON Project No.: 0CP-18-0041 Prepared for: TC United Group. 800 Industrial Ave, Unit 9 Ottawa, ON K1G 4B8 Prepared by: McIntosh Perry Consulting Engineers Ltd. 115 Walgreen Road, RR3 Carp, ON K0A 1L0 March 2, 2018 i Executive Summary McIntosh Perry Consulting Engineers Ltd. (McIntosh Perry) was retained by TC United Group to conduct a Phase One Environmental Site Assessment (ESA) for the property located at 296 Somerset Street East, Ottawa, Ontario (‘the Site’). The Site is bounded to the north by Somerset Street East, and to the east, west, and south by residential dwellings. The Site currently consists of a single family residential building (currently occupied) and a small detached garage. It is understood that this Phase One ESA is being completed as a component of the City of Ottawa site plan submission process, in support of an application to construct a residential building which will include four residential units and one commercial unit on the ground floor. The Phase One ESA has been prepared in general accordance with the requirements of Ontario Regulation (O.Reg.) 153/04 as amended. The report is also in general compliance with “Phase I Environmental Site Assessment”, Canadian Standards Association (CSA) standard CSA Z768-01, reaffirmed 2016. Based on a review of aerial photographs, historical information, and interviews, the Site was developed with the present-day residential dwelling between 1924 and 1928. Prior to this time, the Site was likely vacant. No Potentially Contaminating Activities (PCAs) or Areas of Potential Environmental Concern (APECs) were identified at, on, or under the Site. The following offsite PCAs were identified in the Phase One ESA Study Area: x 308 Somerset Street East – Possible historical use as a dry cleaner and dye manufacturing, processing, and/or bulk storage. x 306 Somerset Street East – Ontario Spill Record (outdoor oil tank ‘weeping’). x 330 Templeton Street – Ontario Spill Record (underground fuel storage tank leak). x 330 Templeton Street – O.Reg 347 waste generator (oil skimmings and sludges). Based on the nature, location, and age of the offsite PCAs, no on-site APECs were identified. A Phase 2 ESA is not deemed to be necessary at this time. ii Phase One Environmental Site Assessment 296 Somerset Street East, Ottawa, ON 0CP-18-0041 TABLE OF CONTENTS 1.0 INTRODUCTION

  • By Email January 15, 2021 Mayor
    By Email January 15, 2021 Mayor Jim Watson 110 Laurier Avenue West Ottawa, ON K1P 1J1 Dear Mayor Watson: Poorly Conceived Ward Boundary Change (uOttawa - Lees Campus) Affecting Capital Ward The Old Ottawa East Community Association respectfully requests that a change made during the course of the Ward Boundary Review be reversed before the by-law is proclaimed January 27, 2021. The change does not meet the City’s criteria required for a ward boundary change. Specifically, on December 9, 2020 City Council approved ward boundary changes that included the transfer of the University of Ottawa’s Lees Avenue campus from Capital Ward to Rideau-Vanier. This transfer was introduced by an unknown party near the end of the lengthy ward boundary consultation process but the Old Ottawa East Community Association and the Old Ottawa East community were not made aware of the change until after FEDCO had blessed it. Specifically, the “Recommendations Report” for Council recommended: “Move the Gee-Gees sports field from W6-19 (Capital) to W6-17 (Rideau-Vanier). The reasons given refer to a better boundary (the River rather than Highway 417) and the area’s association with sports facilities directly to the north in Rideau-Vanier. In the recommended ward boundary configuration, the Gee-Gees sports field is moved from W6-19 to W6-17. There are no residents in this area.” (p23) The report later says: “At Robinson Park and Gee Gees Field, #417 is not a big boundary; use the River instead.” (p34) …/2 - 2 - The fundamental criterion for making ward boundary changes is to “achieve voter parity." The transfer of the Lees campus will be detrimental to voter parity because Rideau-Vanier is forecast to grow faster than Capital.

  • Appendix 5 Station Descriptions And
    Appendix 5 Station Descriptions and Technical Overview Stage 2 light rail transit (LRT) stations will follow the same standards, design principles, and connectivity and mobility requirements as Stage 1 Confederation Line. Proponent Teams were instructed, through the guidelines outlined in the Project Agreement (PA), to design stations that will integrate with Stage 1, which include customer facilities, accessibility features, and the ability to support the City’s Transportation Master Plan (TMP) goals for public transit and ridership growth. The station features planned for the Stage 2 LRT Project will be designed and built on these performance standards which include: Barrier-free path of travel to entrances of stations; Accessible fare gates at each entrance, providing easy access for customers using mobility devices or service animals; Tactile wayfinding tiles will trace the accessible route through the fare gates, to elevators, platforms and exits; Transecure waiting areas on the train platform will include accessible benches and tactile/Braille signs indicating the direction of service; Tactile warning strips and inter-car barriers to keep everyone safely away from the platform edge; Audio announcements and visual displays for waiting passengers will precede each train’s arrival on the platform and will describe the direction of travel; Service alerts will be shown visually on the passenger information display monitors and announced audibly on the public-address system; All wayfinding and safety signage will be provided following the applicable accessibility standards (including type size, tactile signage, and appropriate colour contrast); Clear, open sight lines and pedestrian design that make wayfinding simple and intuitive; and, Cycling facilities at all stations including shelter for 80 per cent of the provided spaces, with additional space protected to ensure cycling facilities can be doubled and integrated into the station’s footprint.

Constructed in 1966/1967, it consists of long twin structures carrying Heron Road over the Rideau Canal (National Historic Site of Canada and UNESCO World Heritage site), the National Capital Commission (NCC) pedestrian pathway, Colonel By Drive, the Rideau River, and the Vincent Massey Park access road. Part of the bridge collapsed during original construction and this tragedy remains one of Ontario’s worst construction accidents in history. Each structure consists of seven spans carrying three lanes of traffic. The north structure is about 267m long and the south structure is 276m long. The superstructure consists of cast-in-place post-tensioned voided concrete deck cantilevered to support three suspended spans. The suspended spans consist of nine simply supported prestressed girders, with reinforced concrete deck. The precast girders are supported by corbels at the ends of the cantilevered post-tensioned deck. The substructure consists of six intermediate piers and abutments at each ends. The piers in the vicinity of the Rideau River are supported on spread footing on bedrock whereas the remaining piers and abutments are supported by piles driven to bedrock.

  • 10.0 Environmental Effects, Significance and Mitigation
    10.0 ENVIRONMENTAL EFFECTS, SIGNIFICANCE AND MITIGATION To a large degree, environmental effects were avoided or minimized to the extent possible due to the nature of the project (i.e., conversion from BRT to LRT); and during the evaluation of the alternatives and the selection of the preferred alternative. Moreover, many mitigation measures have been directly incorporated into the recommended plan. This section describes the environmental benefits and potential environmental effects of the proposed project and mitigation measures for the effects that cannot be avoided. Sections Include: 10.1 Assessment Approach 10.2 Project Benefits 10.3 Impact Assessment Results, Mitigation, Significance and Residual Effects 10.4 Cumulative Effects 10.5 Accidents and Malfunctions 10.6 Municipal, Provincial, Federal or Other Approvals or Permits 10.7 Future Commitments 10-1 • the magnitude, spatial extent, and duration of the effects; irregularities, but would have no measurable effect on the 10.1 Assessment Approach • the proportion of a species population or the number of population, entity or group as a whole.
