This volume of the Final Report contains the Planning Assessment (Chapter I), Environmental Assessment (Chapter 2) and Urban Landscape Assessment (Chapter 3) for the proposed Central Kowloon Route. Volumes 1 & 2 of the Final Report contain the engineering feasibility and o preliminary design report and drawing. o 2. STRATEGIC DEMAND FOR THE CENTRAL KOWLOON ROUTE Fignres Nos. 001 & 002 show the proposed alignment for the Central Kowloon Route and its o relationship with the future strategic road network. The need to improve strategic east-west road links acro.ss Kowloon has been identified in several o previous studies including the Central Kowloon Traffic Study, West Kowloon Reclamation J Transportation Study and the West Kowloon Expressway Study. A broad corridor for a cross o Kowloon route was identified in these studies. During the course of this study it has become evident the Central Kowloon Route will be an integral part of planned redevelopments of lower grade urban areas on the Kowloon peninsula and will be o vital for development of the proposed Kowloon Bay reclamation. o 3. SUMMARY OF VOLUME 3 o a. Planning Assessment 1) Future Land Use o a) The long-term negative effects of the CKR western approaches on land use will be minimal given that: o the plan of the West Kowloon Reclamation has been amended to satisfactorily accommodate the route; o the schools at Tung Kun Street will be retained; placing the route underground will allow redevelopment along the lines o recommended in the West Kowloon Development Statement. b) The underground route will avoid impacting the schools on Wylie Road, the Oi o Man Estate and the Ko Shan Theatre. c) The recommended route for the CKR through the eastern approaches will have o limited land-use impact in the long term. Approaches to minimise construction impacts to Ko Shan Park will be incorporated into the detail design. Further, implementation of the CKR will provide positive stimulus to redevelopment in o areas where the normal operation of the market has been frustrated to date .. o o o Vol3/i o o Parsons Brinckerhoff Maunsell Consuitallts Celltral Kowloon Route Study ., o 2) Physical Constraints o Construction of the Housing Society's Six Streets Redevelopment on Tung Kun Street and of the building at 52 Wing Kwong Street are in progress at the time of issuance of this Report.
