After hearing residents' concerns the council explored an alternative industrial location at 15 Karanema Drive, the site of the fire station, and today councillors will hear the merits and issues associated with each site before being asked to choose one.
Aside from the community opposition to the 25 Karanema Drive proposal, the report noted that choosing this site would have no financial implications since it was already budgeted for, and that while there was strong interest from those potentially affected, wider public interest appeared low.
For the other site at 15 Karanema Drive a small number of potentially affected residents had been spoken to, with minimal opposition at this point, but a significant factor would be the unbudgeted cost.
At a meeting in April council officers were asked to report back on this and said the cost of constructing the booster pump at the fire station site was estimated at $900,000, the bulk of which would be spent on acquiring the land and creating two easements.
This did not include any contingency amounts or costs to complete land and easement transactions and resource consents, and was on top of $3 million that had been budgeted for the project.
"The increase in cost at $900,000 to establish at the fire station site remains a significant increase to the $3m budget ... this, along with other factors, need to be weighed against the community opposition that has been clearly expressed," the report said.
With the land already zoned as industrial, it was likely to have less impact on the surrounding neighbourhood, but while some responses so far had been positive, not all property owners were happy with this location.
"Further consultation will be required with adjacent landowners if this site is chosen," the report said.
In terms of concerns about the building size and appearance if it were built at 25 Karanema Drive, officers said there were options available to soften the visual appearance of the building, and extra mitigation could reduce noise levels.
In determining their preferred option, the report said the pump station had to be up and running by November next year to meet the timeframes for turning off the Brookvale Rd water supply, with the construction period for completion and commissioning predicted to take at least 12 months.
