NAMING OF TITLE BLOCK & DRAWINGS

  • If section details are included in the same drawing sheet as Site Plan, section details shall be annotated clearly in the drawing for example “Cross Section A-A”; “Longitudinal Section B-B” etc. The Drawing sheet Title Block shall be labelled as “ ECM Site Plan & Sections – Location”.

  • If section details are in separate drawing sheets, the drawing sheet title block to be labelled clearly as “ECM Cross Section – Location”; “ECM Longitudinal Section Location” etc.

  • For ECM works that are proposed in multiple phases drawn in the same sheet, each phase shall be clearly annotated as follows: “Site Plan (Phase xx) ”, where xx is the phase number. If each phase provided in different drawing sheets, the sheet title block to be labelled as “ ECM Site Plan (Phase xx) – Location”

    Drawing Title Block Name:

    • ECM Site Plan- Location

    • ECM Cross Section A-A – Location

    • ECM Longitudinal Section B-B- Location

SITES WITH MULTIPLE CATCHMENTS

  • For sites separated into multiple areas with multiple storage ponds:

    • Sub-catchment plans of each area must be submitted, with arrows clearly indicating the flow of water into each storage pond.

    • Physical hump separating the individual catchments to keep the runoff within each catchment shall be provided.
