D05 - Stormwater Drainage Design and D07 - Stormwater Quality
These files enable design submissions to be compliant with Council's Aus-Spec Design Specifications: D05 - Stormwater Drainage and D07 - Stormwater Quality.
Conceptual on-site detention (OSD) calculator to assist in concept level design / sizing of volumes and orifice for infill development only. The tool is not to be used for detailed design, ‘For Construction’ design purposes, or developments on lots larger than 1,200m2. Open the Excel file and click on the macro button “Start OSD calculator CLICK HERE” within the OSD Calculator sheet to initiate the macro-based program. If this tool has been used to assist in development of a conceptual stormwater design for DA purposes, please provide a screenshot of the entire OSD calculator window with the stormwater plan.

Spatial Data Standard(PDF, 294KB)
The Spatial Data Standard explains how spatial data must be created, formatted, and submitted when working with Port Macquarie Hastings Council. It provides a quick reference so consultants and staff and ensures all geospatial information is accurate, consistent, and compatible with Council’s GIS systems to avoid any delays or unnecessary rework.
This document supports activities such as development assessments, infrastructure design, environmental reporting, and any project involving maps or spatial datasets. It tells users what formats, coordinate systems, metadata, and data quality standards are required.
Port Macquarie Hastings Council is committed to the continuous improvement of its engineering specifications, standard drawings and construction standards.
Following the implementation of the updated AUS-SPEC suite in 2024-25, the 2026 update introduces minor amendments to transport and stormwater specifications, along with corrections, clarifications and consistency improvements across the document suite. These changes are designed to improve usability, provide greater clarity for industry stakeholders, and support the delivery of consistent, high-quality infrastructure outcomes across the local government area.
