Flood planning in Penrith — common questions
Is my Penrith property in a flood planning area?
Significant parts of Penrith are in flood planning areas. The Nepean River, South Creek, and their tributaries create extensive flood-affected areas. Properties in Emu Plains, Penrith CBD, and low-lying western suburbs should check their status.
What are the main flood risks in Penrith?
The Hawkesbury-Nepean River system and South Creek are the primary flood sources. Penrith is part of the Hawkesbury-Nepean catchment, which has one of the largest flood risk exposures in Australia. Major flood events occurred in 2021 and 2022.
Does flood risk overlap with bushfire in Penrith?
Yes. Properties along the Nepean River corridor may face both flood and bushfire constraints — flood from the river and bushfire from adjacent Blue Mountains vegetation. Dual constraints increase development assessment complexity.
Can I build a granny flat on a flood-affected Penrith property?
Under SEPP Housing 2021, flood control lots are excluded from the CDC pathway. Given the extent of flood-affected land in Penrith, checking flood status before planning a granny flat is essential.
