MINOR

The bill was updated from Session 1 to Session 2, reflecting changes in legislative sponsors, dates, and page numbers. The core policy requirement remains the same: county water boards must publish maps showing where residential water service is available. However, the maps must now also include a specific inventory of unfulfilled or incomplete improvements funded by developers, providing more transparency on why service might be unavailable in certain areas.

Scope change

The scope of the disclosure requirement was expanded to explicitly include information about owed, unconstructed, or incomplete developer-funded improvements on the reference maps.

REQUIREMENT

Mandated inclusion of the board's inventory of unfulfilled, unconstructed, or incomplete developer-funded improvements on service availability maps.

TECHNICAL

Updated legislative metadata including sponsor names, dates, page numbers, and session designation from SD1 to SD2.

Minor grammatical adjustment in the description section changing 'its website' to 'their websites' for plural agreement with 'boards'.
