INTRODUCTION The "flying fields" of yesterday are the "airports" of today, rapidly developing into the "air terminals" of tomorrow. The days of the airplane as a novelty for barnstorming are over. The airplane has not only proved itself an efficient, fast, and reliable method of trans- portation; but also a luxurious, better, and safer way to transmit passengers, mail and freight. The airplane has been developed to a high state of pre- fection. The only obstacle in its path of progress today is the lack of adequate and properly equipped airports. The need for paved surface runways has been clearly demonstrated during the past three years. In the United States a few years ago the planes in general use were light, one to three-passenger, weighing less than two tons. For these almost any smooth dry field was sufficient. hath the development of extensive air mail, express and pass- enger traffic, however, new demands are brought upon.the surface of the airport. Standard commercial planes in the United States today weigh as much as 22,500 pounds,85% of which is carried on the two front vheels. The impact is often two to three times this weight. Almost every type of hard surfacing has been tried out in various parts of tie country, with varying degree of success. Concrete has bcen found the most satisfactory and economical in the end.

Field illumination is provided by two batteries of in- candescent floodlights, each containing s x 3000-watt units spaced 8 feet apart. Obstacle lirhts are placed on electric power poles on the south side of the field, the only ov- erhead projection within a mile of the field on all four sides. Voters of Pontiac approved a $180,000 bond issue for the airport on Kay 8, 1928. The site was selected from thirteen available areas and purchased on September 12, 1928. The port was offically opened Rovember 27 with the inauguration of air-mail service by Thompson, Pontiac be- ing the northern terminal of the Pontiac—Detroit-Kalama- zoo route. The field vas dedicated June 15, 1929. At present, tne airport and equiplment represent an inves ment of $300,000, of which $110,000 represents tLe cost of the Thom son plant. The remaiuter, spent by the city, came from the $180,000 b nd issue, which provided 9; for the cost of the initial ISO-acre site, the hangar an lighting equipment and from additional funds supplied on cf of the buaet for the purchase of an additional BO-acre tract and operatina expenses.

This should not be adopted without further study however. It is merely a suggested plan which might be used. As this work is supposed to cover an estimate of the cost only, this will serve the purpose. Any drainage system used will cost approximately the same.
