• Any development adding 1,000-4,999 sf of impervious pavement, roof, or other hard surface is required to design and install a stormwater runoff reduction measure such as an infiltration trench or engineered rain garden. The intent is for this new hard surface to drain to this measure and soak in the first inch of water runoff.
• Any development adding or replacing 5,000 sf or more of impervious pavement, roof, or other hard surface is required to design and install a full detention measure. This measure is designed by a professional engineer to infiltrate the first inch of rain and slow down the remaining runoff to predevelopment rates. Most of the practices used to accomplish this in residential lots are underground vaults, pipes, or rock filled trenches.
These requirements can be found in Section 3 of the Alpharetta Stormwater Policy Handbook on the city’s website here: https://www.alpharetta.ga.us/docs/default-source/public-works/stormwater/alpharetta-stormwater-policy-handbook.pdf?sfvrsn=5746cfab_12
