In 2005, the City of Irvine released a detailed plan for funding the development and maintenance the Orange County Great Park at the former Marine Corps Air Station at El Toro. The plan reflects the revenues and costs associated with the Master Plan as adopted by the Orange County Great Park Board. Heritage Fields, LLC will participate in the development and maintenance of the Great Park through three commonly used financing mechanisms for public improvements in California master planned communities:

• Community Facilities District Bonds for streets and utilities
• Special levies for maintenance similar to a Master Homeowners Association
• Development Agreement fees in the amount of $200 million
• Redevelopment Agency Bonds

An additional $201 million in infrastructure capital improvements will be paid through property tax assessments. Special levies will pay for maintenance costs.

• Public streets, utilities, drainage, entryways and street landscaping required for the park and surrounding community.
• Park and open space improvements, including the sports park, Meadows Park , and wildlife corridor.
• Required maintenance and services for the parks, open space, public streets and landscaping.
• Requisite infrastructure for the museum district.

In addition to these financing mechanisms specifically created to fund on-site improvements at the Great Park, the City of Irvine has adopted a comprehensive fee program to fund all measures required to mitigate traffic impacts resulting from development in the northern portion of the City. This program, known as the North Irvine Transportation Mitigation (NITM) Program, provides fair share funding to make traffic improvements that will provide City-adopted levels of service at locations that the NITM analysis indicates may be deficient in the future.
