1 - Introduction

1.1 Scope of this Chapter

This chapter applies to all land in the Kempsey Shire local government area.

This chapter applies to all subdivision and development where engineering/civil work is to be undertaken in conjunction with the proposed development.

1.2 Relationship to Other Chapters of this DCP

The provisions contained in Chapters included in Parts C, D, E and F of this DCP override the provisions of this Chapter to the extent of any inconsistency.

2 - Chapter Objectives

The objectives of this Chapter are:

1. To adopt a Design and Construction Development Specification series prepared in consultation Council’s Infrastructure Services Department.
2. To provide developers, their agents, consulting Surveyors/Engineers and Civil Contractors with Council’s minimum requirements for the design and construction of all civil works to be undertaken in the Kempsey Shire local government area.
3. To provide a degree of certainty to developers, their agents, consultant Surveyors/Engineers and Civil Contractor as to Council’s minimum requirements for design and construction of civil works.
4. To encourage more innovative subdivision design, efficient site usage, and minimize the cost of urban infrastructure and servicing in a manner that maintains equal access to public infrastructure, given the physical limitations of any one site and the provisions of Kempsey Local Environmental Plan 2013 and other Chapters of this DCP.
5. To minimize Council’s costs associated with maintenance of future public infrastructure.
6. To employ ameliorating measures sufficient to reduce the impact of development on the existing natural and man-made environments.
7. To limit development in the Kempsey Shire to development that complies with the provisions of Council’s Flood Risk Management Policy and plans.
8. To streamline the existing approvals process under the Environmental Planning and Assessment Act 1979 (issue Construction Certificates by Council), the Local Government Act 1993 (Section 68 approvals by Council) and the Roads Act 1993 (Section 138 approvals by Council) for civil engineering work associated with subdivision and development in accordance with Council Policy No.60 - Guide for Certification of Civil Engineering Design Work.
