RFI - Ecological Assessment Report

OPERATIONAL PHASE                                                                                              5-3

       Strategy:           Implement appropriate inspection and maintenance regimes to ensure optimum
                           ongoing function of all stormwater and water quality maintenance features.

       Actions to be as follows:

       Developer
        1.    Carry out monitoring of surface water quality at locations indicated in Appendix D (and as
              advised by Superintendent) in accordance with the monitoring section of this element of the
              EMP (see Element C.5 (b).
        2.    Monitoring parameters for sampling for surface waters to be as per Construction program (refer
              Element C.5(b). Frequency of monitoring to be every third month and after significant rainfall
              events (at least two per year) for a period of 3 years from the final stage of construction.
        3.    Carry out monitoring of water quality at a minimum of three (3) developed allotments rapid
              infiltration pits for a minimum period of one year after establishment of the subject allotments
              community management statement. The pits to be monitored are to be determined in liaison with
              Council.
        4.    Monitoring parameters and frequencies for rapid infiltration pits will be as indicated in Element
              C.5 (b) with sampling to be conducted after each significant rainfall event (>50mm/day) with a
              minimum of two sampling events per year. Baseline water quality compliance levels will be
              determined from the baseline monitoring of infiltration conducted during the preconstruction and
              construction program.
        5.    The Landscape Master Plan provides details on swale species and establishment procedures.
              Details on the monitoring and maintenance procedures for swales and the timing of such
              monitoring are described below in Maintenance Procedures - Swales.

       Bodies Corporate

        The following points are to be elaborated on in the respective Community Management Statement:
       1.     Inspect rapid infiltration pits after each significant rainfall event (>50mm/day).
       2.     Ensure grated inlets are free from debris and blockages and remove as required.
       3.     Inspect base of pit for debris and blockages, build up of leaf litter and humus and remove as
              required.
       4.     Inspect base of pit for retained water.
       5.     Remove and replace upper geofabric filter layer in rapid infiltration pits at 6 monthly intervals.
       6.     Remove and replace upper sand filter layer in rapid infiltration pits at three yearly intervals or as
              required.
       7.     Inspect overflow weirs adjacent rapid infiltration pits for signs of surcharge and scour after each
              significant rainfall event.

       Monitor condition of swales in accordance with the specification provided below and remediate as
       required.
