RMU SET BACK FROM R.P. STREET ALIGNMENT
When planting vegetation in parklands, ensure vegetationdoes not encroach on the ring main unit site.Take into consideration the fully matured size of vegetationto allow continuing access to the site.
A ring main unit in parkland shall be located:
The location of ring main unit sites is based on acceptable separation to adjacent dwellings located as shown. Any reduction in the 1.5m minimum dimension shown on the drawings requires a corresponding relocation of the ring main unit site to maintain the acceptable separation.
LOCATION IN COUNCIL PARKLANDS
A 3.0m wide cable and access easement or road reserveshall be provided between the ring main unit site and the R.P. Street Alignment.
