Abstract

These best practice guidelines have been prepared to assist regional and local authorities, consultants, roading engineers and contractors with the design of appropriate waterway crossings within the Waikato region. By following the recommendations in this handbook, proposed waterway crossings:

• will be designed to have the minimum possible adverse impact on the environment
• will be consistent with the requirements of the Waikato Regional Plan.
• will not compromise the levels of service provided by regional and district flood protection or land drainage schemes.

The topics covered by this best practice guideline handbook include:

• the Waikato Regional Plan
• flood control schemes and land drainage areas
• best practice design guidelines for waterway crossings.

Note: This report was originally published in May 2006 as Technical Report 2006/25. This new edition corrects a minor data error which appeared in Appendix 2, on the first line of page 27. The word ‘minutes’ was accidentally substituted instead of ‘hours’ in a ‘time of concentration formula’. While addressing this error, the opportunity was taken to make some other minor typographical changes. These changes make no difference to the conclusions or recommendations in the report, but in the interests of data accuracy we are re-releasing this publication.
