Staff Recommendations should be followed. Staff Recommendations: Care should be taken to allow normal surface: -water flow to the flood plain area, South and East of the development. Engineers should confirm there is adequate separation between the bottom of ponds infiltration areas, and post - development seasonally high ground water tables. Maintenance access should be provided to all preservation and infiltration areas proposed.
