An Act To Address Housing Density Requirements In Sole Source Aquifer Island And Peninsular Communities

LD 1914 creates a temporary exemption for certain island and peninsula municipalities in Maine that rely on a single groundwater source (a "sole source aquifer") from mandatory housing density increases. It requires these municipalities to hire a licensed geologist to evaluate groundwater and septic capacity before allowing denser development. The evaluation must assess soil, water supply impact, septic system capacity, and saltwater proximity. If the assessment shows capacity, the municipality must update zoning to allow density increases; if not, they remain exempt. This applies to municipalities like those on islands or peninsulas designated under EPA guidelines for sole source aquifers.
