Outlined below is information on the standard requirements for engineering drawings that are submitted to council.
General
- The planning permit number SD/D-202#/###### clearly on each drawing.
- Plans must follow the relevant Planning Permit and the conditions.
- Both the horizontal and vertical scale is to be shown on each drawing.
- Detail the existing and proposed use of the site.
- Detail the boundaries and dimensions of the site.
- The topography including 1 metre or less contours showing AHD levels and major site features.
- Natural drainage lines, watercourses, and wetlands on or adjacent to the site are to be shown.
- The location and capacity of any existing services or easements on the site or connected to the site.
Car parking and driveways for any development
- The design is to follow Australian standard AS2890.1:2004 (as required by C2.0 Parking and Sustainable Transport Code), Tasmanian Standard Drawings and the Local Highway Standard Requirements By-Law.
- The basic dimensions of the proposed roads, driveways, car parking areas, cycleway parking areas, and footpaths within the site.
- Proposed grades and fall direction of grades for parking and manoeuvring areas.
- Spot levels to the perimeter of the pavement at a max of 4m centres and all corner points.
- Spot levels to surface pits and invert levels of the pits.
- Plan to include all kerbing which is to be clearly marked.
- All saw cuts and construction joints are to be specified.
- A long section may be required for driveways in cases where it is deemed necessary, typically greater than 10 percent showing the change of grades.
- A cross-section of the pavement is required that shows:
- sub-base thickness
- concrete thickness
- concrete strength
- reinforcement specification
- kerb specification
Revisions
- The plan should clearly notate the drawing and revision number/letter.
- Any revised drawing should clearly display revision clouds.
- Any revised drawing should maintain compliance with previous planning approvals.
Roads and services (urban or rural)
- General layout complying with Tasmanian Standard Drawings and Local Highway Standard Requirements By-Law.
- Details for roads and stormwater, including any easements, lot connections access, laneway or footways.
- Typical sections showing subsoil drain, pavement, kerb and channel, and footpath.
- Long sections of stormwater and roads.
- Cross-sections showing batter extent, any structure and proposed property boundary.
- Details for any traffic management devices including a separate plan for line marking and signage.
- Draft services plan (TasNetworks and TasWater).
- Landscaping plans.
- Soil and sediment management plan (this can be submitted prior to the Start of Works notice.
Stormwater
New developments are required to meet certain conditions in relation to stormwater management as per the Urban Drainage Act 2013 and the Planning Scheme.
For further information, please see the Stormwater Management for New Developments Procedure.

Stormwater treatment
If there is a requirement for stormwater treatment, the following applies:
- Proprietary systems should be specified with invert levels, details and maintenance schedules. The designer will need to demonstrate that the treatment facility is adequate in accordance with the state stormwater strategy. This can be done via a ‘MUSIC’ model or other propriety software for stormwater treatment.
- Should the designer elect to include a bespoke treatment train, the following is required:
- Long sections
- Cross-sections
- Plant specifications
- Pit and pipe specifications
- Filter media specifications
- The design is to clearly demonstrate the capacity of the facility with HGLs
- Maintenance schedules are required.
Stormwater detention
If there is a requirement for stormwater detention, a detail of the detention facility is required with invert levels. A supporting stormwater report may also be required that demonstrates the pre and post flow rates are acceptable.
Works in road reserve
Should there be work within the road reserve, the plan is to include the notation “a work in road reservation permit from Clarence City Council is required for this work.”
