What happens to a lot in a subdivision if it does not perc?

When a lot in a subdivision does not perc—meaning it fails to meet the percolation test requirements for installing a suitable sewage system—it cannot be developed for residential use as intended. Consequently, the lot options become more limited.

A lot that does not perc can sometimes be absorbed into another lot, allowing the adjoining property owner the possibility of expanding their property or increasing the size of their lot. This solution helps to maintain the land's usability and value, as the non-perc lot becomes part of a lot that can be developed. The practice of grouping lots in this way can also help avoid leaving unusable land within a subdivision.

Understanding the implications of a lot not percolating is important for property development within subdivisions, as it speaks to the regulations governing land use and the necessity of proper waste management systems.
