Quick answer: Avondale Estates is a century-old planned village of 1920s Tudor homes — and its stormwater system is showing its age in the city’s own engineering reports. The city’s Urban Redevelopment Plan describes a North Woods project at Lake Avondale to solve a stormwater problem causing “extensive flooding, bank erosion and lake sedimentation,” and a Kensington Road drainage analysis found that undersized pipes were flowing under pressure and “causing the flooding that has been observed.” The city’s comprehensive plan notes no FEMA-mapped 100-year floodplain — but also “minor urban flooding in parts of the city during intense rain storms.” If water is entering your Avondale Estates home, call PuroClean of East Cobb at (770) 627-0900. We answer 24/7 with a live person and respond in 60 minutes or less.

Avondale Estates was founded in 1924 by pharmacist George Francis Willis, who modeled it on Stratford-upon-Avon — Shakespeare’s birthplace in England — as one of the first planned communities in the Southeast. The vision held: the city’s housing stock is still predominantly 1920s through 1940s, in Tudor Revival, Colonial Revival, Craftsman, and Mediterranean Revival styles, with mid-century ranches near Lake Avondale. The downtown Tudor commercial district is listed on the National Register of Historic Places (1986), and a local historic district imposes binding design guidelines on exterior changes. It is a beautiful, coherent, century-old city. Its drainage, in places, is just as old as the buildings — and it was sized for a quieter century.
The city’s own engineers on the flooding
This is not speculation — it is in the city’s published documents. The Urban Redevelopment Plan for the Lake Avondale park describes a multi-phase project whose first phase focuses on stormwater mitigation in the park’s North Woods area, because the stormwater issue there is causing “extensive flooding, bank erosion and lake sedimentation.” A separate Kensington Road drainage analysis is blunter: its pipe analysis showed that a portion of the pipe system “flows under pressure through undersized pipes,” with the hydraulic grade line above the top of several structures — “thus causing the flooding that has been observed.” Yard inlets and catch basins, the analysis added, often cannot accommodate the runoff they receive.
The city’s comprehensive plan fills in the context: no stream in Avondale Estates carries enough volume to earn a FEMA-mapped 100-year floodplain, but “minor urban flooding in parts of the city during intense rain storms” is an acknowledged fact of life. The lowest point of elevation — 940 feet, at Cobb Creek near Memorial Drive — is exactly the kind of spot where water gathers when the pipes give up.
What stormwater does to century-old homes
A 1920s Tudor was built before storm sewers were sized for today’s rainfall intensity — and before modern foundation waterproofing existed. When the street’s drainage is overwhelmed, water takes paths the designers never intended: through basement window wells, under garage doors, and against foundation walls that have had a hundred years of soil pressure and freeze cycles to work on them.
There is also the preservation factor. Exterior changes in the historic district require Historic Preservation Commission review — which protects the city’s character, but means drainage improvements around a home need planning, not improvisation.
When the storm finds the weak spot
1. Watch the low points during heavy rain. If water is ponding near the foundation or rising in a window well, it is already past the drainage system’s capacity.
2. Move what you can off basement and ground floors. Stormwater carries street and yard runoff — don’t treat it as clean.
3. Document the water’s path — entry points, depths, and everything it touched. That record protects your claim.
4. Call (770) 627-0900. Mold can start within 24 to 48 hours, and century-old framing and plaster soak it up. Professional drying reaches the moisture that fans and dehumidifiers from the hardware store leave behind.
