Low spots, thin soil and heavy summer rain
Older, flat streets can have low spots where water collects after each storm. Soil is typically thin and alkaline over limestone, and many lots have been compacted over decades. Grass in that kind of ground can look patchy no matter how often it is watered.
The remedy starts with the ground. Loosening the soil, improving the top layer and setting a gentle slope away from the house make a big difference. Where water has nowhere to go, a French drain, a dry well or a swale can help. Planting beds raised slightly above grade also keep roots out of standing water. We explain the logic so you can judge whether the fix makes sense.
