Node Neighbourhood focal points, nodes are highly visible locations which serve as meeting places for residents or one or more neighbourhoods and have a clear identity as neighbourhood locations. They can be functional or natural. Boulevard Boulevards are arterial routes provided with large street trees with a continuous and consistent landscape treatment. The landscape treatment often emphasises a formal design pattern. Overhead utilities are eliminated or reduced along a boulevard. Features include widened footpaths, special footpath treatments, crosswalk paving materials and other public amenities. Parkway A continuous freeway which traverses a park or parkland setting in an urban environment. In this submission the word is interchangeable with the description of a boulevard. Shared Path These are priority routes for pedestrians and cyclists. A pathway adjacent to the road. Bundling Overhead power and/or telecommunications lines that could be ‘bundled’ and placed in conduits and/or trenches underground. Dive structure The retaining structure and feature claddings diving to the entrance to a tunnel entrance or portal. Portal The face and retaining structure immediately above the tunnel entrance, generally located perpendicular to the dive structure. Noisewall A wall created to mitigate and deflect the effects of predominantly traffic noise. 1.0General 1.1Report Objective This report describes the project’s urban, architectural and landscape design proposals. The design of the various project components is developed through an integrated urban design team approach. This approach encourages a continuous component evolution and refinement throughout the tendering period. The components, would of necessity, receive further development at the construction stage, arising from detailed engineering requirements, constructional constraints, community consultation and Authority approvals. Further design modifications are also anticipated as an outcome of the community consultation process. View of Observatory Park.

It would provide a motorway-standard tunnel connection between the Hills M2 Motorway and the M1 Pacific Motorway, and would considerably reduce North-South travel time through the Sydney metropolitan area. Surface roads through the Pennant Hills and residential areas would likely experience reductions in traffic, resulting in improvements in the connectivity and permeability of their urban fabric. There would also be an extension of current art and cultural elements and the introduction of themed elements to enhance aesthetics associated with the project. 2 | May 2014 | NorthConnex North West Rail Link Proposed Railway Existing Northern Railway Line & North Shore Railway Line 0 250 500 750 1000 1250m SCALE 1:25000@A3 M1-M2-5000-DR-UD-0001 LOCAL ANALYSIS - GENERAL CONTEXT SOUTHERN INTERCHANGE NORTHERN INTERCHANGE Northern ventilation facility Motorway operations complex Trelawney Street tunnel support facility Wilson Road tunnel support facility HORNSBY SHIRE COUNCIL HORNSBY BEROWRA VALLEY NATIONAL PARK A ffy Ed ern oad e ft R Lin cro Railway Bee ock ad ay hway Fox Valley Road ee k e ov er Riv ic Hig LANE COVE NATIONAL PARK La s Ro ue WAHROONGA rkw Pacif Ro ad lls Hi an t Pe nn rra na Pa C ne th R C IFI AC WAY P M1 TOR A v MO y Line me Cr vid Pearces Corner Co ns Da rn the r No ad rth en e k vli il Lin st Ra Nor h We CARLINGFORD De BEECROFT Pennant Hills Ro wo Railwa Th Nort HILL MOT S M2 ORW AY ic Hig hway PENNANT HILLS NORMANHURST Pennant Hills Golf Club NORMANHURST Pacif Brickpit Park No Wil Ro son ad Observatory Park Tr St elaw ree ne y t e i ant H Penn THORNLEIGH hor Thompsons Corner ad lls Ro th S rth e WEST PENNANT HILLS ge Nor nu ve oad oad ill R ry R Du nda tle H WAITARA Railway Bou Line WEST PENNANT HILLS Cas THE HILLS SHIRE COUNCIL WARRAWEE CARLINGFORD NORTH LEGEND NorthConnex Waterways Existing Major Roads Pennant Hills Road / Pacific Highway North West Rail Link Proposed Railway Existing Northern Railway Line & North Shore Railway Line 0 250 500 750 1000 1250m SCALE 1:25000@A3 M1-M2-5000-DR-UD-0002 PROJECT FAMILIARISATION NorthConnex | May 2014 | 3 1.0General 1.3Document Review To understand the existing conditions, an analysis of the route was undertaken, examining specific sites at both a macro and micro level. 1.4Macro Analysis HORNSBY SHIRE COUNCIL 1.4.1 Urban and Landscape Typology HORNSBY BEROWRA VALLEY NATIONAL PARK Line Ed Observatory Park e Lin s Ro ad ic High way ay ay Fox Valley Road Highw Railway LANE COVE NATIONAL PARK IC CIF Y PA WA M1 TOR A ve MO n WAHROONGA rkw Pacif ic cro Bee Ro ad ills tH nn an Pe ock rra th R Pa ern rth No vid y Line ft R oad e na Link Nor BEECROFT ad Da ue me t Rail CARLINGFORD Wes HILL MOT S M2 ORW AY Pennant Hills Golf Club North • Built form responses.
