Wardens will help communities in Cornwall react quickly to the threat of floods.
Cornwall Community Flood Forum will provide flood management training to 100 wardens and raise awareness among other organisations in the county about the potential problems that flooding could cause and how to handle them.
The forum, based in St Austell, will kit people out in high visibility vests, and purchase training manuals, road signs, sandbags and sheeting thanks to lottery funding.
A £9,750 grant from Big Lottery Fund's Awards For All scheme will also pay for the wardens to receive first aid and health and safety training.
It is one of 57 projects in the South West to share more than £457,000 from Awards For All.
Across the region, charities are using the grants to fund their work with people who have mental health problems, looked after children and those facing economic hardship.
Devon's Axminster Awareness Centre will use its grant of £7,992 to establish a food bank and youth farm resource for people who are facing economic hardship and struggling to afford the rising cost of living.
Stonehouse Action, in Plymouth, will create an outdoor art gallery through its grant of £9,934.
