Quick answer:<\/strong> Avondale Estates is a century-old planned village of 1920s Tudor homes \u2014 and its stormwater system is showing its age in the city\u2019s own engineering reports. The city\u2019s Urban Redevelopment Plan describes a North Woods project at Lake Avondale to solve a stormwater problem causing \u201cextensive flooding, bank erosion and lake sedimentation,\u201d and a Kensington Road drainage analysis found that undersized pipes were flowing under pressure and \u201ccausing the flooding that has been observed.\u201d The city\u2019s comprehensive plan notes no FEMA-mapped 100-year floodplain \u2014 but also \u201cminor urban flooding in parts of the city during intense rain storms.\u201d If water is entering your Avondale Estates home, call PuroClean of East Cobb at (770) 627-0900<\/a>.

Avondale Estates was founded in 1924 by pharmacist George Francis Willis, who modeled it on Stratford-upon-Avon \u2014 Shakespeare\u2019s birthplace in England \u2014 as one of the first planned communities in the Southeast. The vision held: the city\u2019s 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 \u2014 and it was sized for a quieter century.<\/p>\n\n\n\n

The city\u2019s own engineers on the flooding<\/h2>\n\n\n\n

This is not speculation \u2014 it is in the city\u2019s 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\u2019s North Woods area, because the stormwater issue there is causing \u201cextensive flooding, bank erosion and lake sedimentation.\u201d A separate Kensington Road drainage analysis is blunter: its pipe analysis showed that a portion of the pipe system \u201cflows under pressure through undersized pipes,\u201d with the hydraulic grade line above the top of several structures \u2014 \u201cthus causing the flooding that has been observed.\u201d Yard inlets and catch basins, the analysis added, often cannot accommodate the runoff they receive.<\/p>\n\n\n\n

The city\u2019s comprehensive plan fills in the context: no stream in Avondale Estates carries enough volume to earn a FEMA-mapped 100-year floodplain, but \u201cminor urban flooding in parts of the city during intense rain storms\u201d is an acknowledged fact of life. The lowest point of elevation \u2014 940 feet, at Cobb Creek near Memorial Drive \u2014 is exactly the kind of spot where water gathers when the pipes give up.<\/p>\n\n\n\n

What stormwater does to century-old homes<\/h2>\n\n\n\n

A 1920s Tudor was built before storm sewers were sized for today\u2019s rainfall intensity \u2014 and before modern foundation waterproofing existed. When the street\u2019s 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.<\/p>\n\n\n\n

There is also the preservation factor. Exterior changes in the historic district require Historic Preservation Commission review \u2014 which protects the city\u2019s character, but means drainage improvements around a home need planning, not improvisation.<\/p>\n\n\n\n

When the storm finds the weak spot<\/h2>\n\n\n\n

1. Watch the low points during heavy rain.<\/strong> If water is ponding near the foundation or rising in a window well, it is already past the drainage system\u2019s capacity.<\/p>\n\n\n\n

2. Move what you can off basement and ground floors.<\/strong> Stormwater carries street and yard runoff \u2014 don\u2019t treat it as clean.<\/p>\n\n\n\n

3. Document the water\u2019s path<\/strong> \u2014 entry points, depths, and everything it touched. That record protects your claim.<\/p>\n\n\n\n

4. Call (770) 627-0900<\/a>.<\/strong> 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.<\/p>\n\n\n\n
