Burnham's city planning projects did not stop at Chicago though. Burnham had previously contributed to plans for cities such as Cleveland (the 1903 Group Plan), San Francisco (1905),Manila (1905,) and Baguio in the Philippines, details of which appear in the 1909 Plan of Chicago publication. His plans for the redesign of San Francisco were delivered to the Board of Supervisors in September 1905, but in the haste to rebuild the city after the 1906 earthquake and fires Burnham's plans were ultimately ignored. In the Philippines, Burnham's Plan for Manila never materialized due to the outbreak of World War II and the relocation of the capital to another city after the war. Some components of the plan, however, did come into fruition including the shore road which became Dewey Boulevard (now known as Roxas Boulevard) and the various neoclassical government buildings around Luneta Park, which very much resemble a miniature version of Washington, D.C., in their arrangement.
When Burnham was in his fifties, his health began to decline. He developed colitis and in 1909 was diagnosed with diabetes, which affected his circulatory system and led to an infection in his foot which was to continue for the remainder of his life.
