APPENDIX C: SANITARY SEWER FIGURES APPENDIX D: WATERCAD MODEL RESULTS AND POTABLE WATER FIGURES iii PROJECT DESCRIPTION The Canal Crossing Redevelopment Area is a separate distinct redevelopment area within the City of Jersey City, and consists of approximately 111 acres located in the southeastern section of Jersey City. It was formed from the southern portion of the Morris Canal Redevelopment Area. The Morris Canal once traversed the redevelopment area in a general north & south alignment near the western edge of the redevelopment area. A small portion in the western part of the site consists of trees and low lying vegetation, while the remainder of the site is developed with industrial uses. NJ TRANSIT’s Hudson-Bergen Light Rail system runs along both the northern and eastern borders of the site. The Westside connector branch of the HBLR forms the northern border of the redevelopment area and the Garfield Avenue station is located at the northwest corner of the site. The Redevelopment Plan envisions a neighborhood incorporating the best principals of sustainable development,
