What should be marked on lots regarding the absorption areas in subdivision planning?

In subdivision planning, it is crucial to accurately mark the corners of both primary and secondary absorption areas on lots. These absorption areas refer to the designated zones where wastewater systems, such as septic systems, can effectively absorb and treat waste. Proper identification of these areas is essential for ensuring compliance with health regulations and environmental safety standards. By marking the corners, planners can ensure that future construction or landscaping does not disturb these critical zones, which could lead to system failures or environmental contamination.

The inclusion of these markers helps ensure that developers, builders, and property owners are aware of the limitations associated with these areas, preventing encroachment. Proper planning in this regard also assists in maintaining the overall integrity of the subdivision's infrastructure and contributes to effective land use management.

In contrast, while it is important to be aware of neighboring property boundaries, existing utilities, and trees on the property, these aspects do not hold the same critical relevance in the context of wastewater absorption capabilities. They serve different purposes in the planning process but are not as directly tied to the functional aspects of sewage management as the corners of the absorption areas are.
