According to Grant Assurance #29, what must be kept up to date in relation to the airport layout?

In relation to Grant Assurance #29, the requirement to keep the Airport Layout Plan (ALP) up to date is specifically focused on the physical development and operational needs of the airport. The ALP serves as a critical tool for airport planning, providing a graphical representation of existing and proposed facilities, ensuring that development is consistent with safety standards, regulatory compliance, and future growth projections.

Keeping the ALP current allows for effective management of land use surrounding the airport, coordination of development projects, and communication with stakeholders, including regulatory authorities. It also plays a significant role in acquiring funding for airport improvements and expansions, since many federal and state funding programs require an up-to-date ALP as part of the grant assurance conditions.

This understanding emphasizes how important it is to maintain accuracy in airport planning documents, such as the ALP, to ensure the airport operates efficiently and remains compliant with applicable regulations and assurances.
