Te Manu Reserve has been subject to slips in the past. Stormwater from Matipo Terrace was not piped or controlled and was simply discharged onto the slopes of the Reserve.
During heavy rainfall in 2014 stormwater caused a slip to occur on the Reserve, leading to a large quantity of vegetation being carried down to Emano Street.
This stormwater work will build a new channel to reduce the risk of slips in the reserve and, by piping the runoff under Emano Street, increase vehicle safety in rainfall events.
The proposed channel will initially discharge into a bio retention swale at the base of the reserve before being piped under the road to Toi Toi Stream. A bio retention swale is a small vegetated dip that can capture sediment from stormwater.
A walking track linking Matipo Terrace to Emano Street will also be constructed at the completion of the project.
