Impervious surface mapping for urban flood and pollution control
Greg Paterson and Leisa Small.
Paper to Stormwater Industry Association Conference, Orange, NSW, April
2002.
|
The paper describes the technology developed by Auckland City to produce
impervious area maps on a property-by-property basis for the whole of the
city. The methodology was required to:
- be non-intrusive method (eg not requiring physical access to
properties)
- be repeatable in future years, to quantitatively assess changes over
time
- provide a reliable basis for potential future user-charging
- be cost-effective.
The paper gives examples of the map outputs, along with a summary of
the uses to which the maps are put.

Development of Auckland's on-site stormwater management programme
Murray Menzies and Greg Paterson.
Paper to Stormwater Industry Association Conference, Orange, NSW,
April 2002.
|
The paper documents progress by Auckand City in developing and implementing
its on-site stormwater management programme. The programme was developed
with close attention to applicable precedents, from North America, the UK
and Australia. The paper documents the rationale for developing the manual
and addresses the allied efforts involved in facilitating the on-site
programme, both within Auckland City and with stakeholders.

Auckland's on-site stormwater management programme: A cost-effective
response to urban intensification
Murray Menzies and Greg Paterson.
Paper to New Zealand Water and Waste Association Stormwater Conference,
Hamilton, June 2002.
|
The paper documents the development of Auckland City's on-site
stormwater management programme, which provides for the implementation of
on-site detention or retention measures to meet specified peak flow and
water quality control targets.
The paper documents the steps in developing the programme, including
the initial feasibility study and the preparation of the on-site manual.
As well as explaining the content of the manual, the paper illustrates
this with an example of an OSM device, namely the stormwater planter.

Auckland City's innovative 'at-source' stormwater management programme
Michael McQuillan and Murray Menzies.
Paper to Novatech 2004 Conference, Lyon, June 2004.
|
The paper explains how growth pressures, combined with increased
emphasis on environmentally sustainable practices, led Auckland City to
develop a multi-faceted at-source stormwater management programme. The
paper describes how original innovation was overlaid onto overseas
precedents for components of the programme, including:
- impervious area mapping
- on-site stormwater management for quantity/quality control
- proprietary catchpit filter devices, to capture litter and sediment
at source
- integrated catchment studies
- research into a user-charging regime

Auckland City's stormwater catchpit filter field and laboratory testing
programme
Grant Ockleston and Kevin Butler.
Paper to New Zealand Water and Waste Association Stormwater Conference,
Rotorua, May 2004.
|
The paper documents the results from a field and laboratory testing
programme undertaken by Auckland City to assess the performance of a range of
commercial catchpit filter systems (CFS). Four manufacturers submitted CFS
units for the field testing programme. Each was installed in a city street
and observations made over a 5 month period covering: ease of fitting,
sediment retention, maintenance needs, rigidity/strength, ability to catch
flows and the effects of litter/organics. The paper summarises the
observations.
On the basis of the field results, CFS units from two manufacturers
were judged as warranting laboratory testing. This testing, carried out at
Auckland University, sought to quantify the sediment capture performance.
The mode of testing and the results are presented in the paper.

Paper to Third South Pacific
Conference on Stormwater and Aquatic Resource Protection, Auckland, May
2003. |
The paper documents the steps and processes applied in developing
Auckland City's on-site stormwater management programme. Key aspects of
the design of the programme were to get, prior to its external
implementation, political buy-in at the outset and to nurture the internal
change management process with council staff. The paper documents the
rationale applied in facilitating the programme, both within the City and
with stakeholders. Comments are given on the experience and the lessons.
