Successful developers of industrial and office parks have found that providing certain amenities is highly effective in attracting tenants, according to Eric B. Eicher, president of the National Association of Industrial and Office Parks.

Eicher, who also is a principal in development of Sabal Park, Tampa, Fla., said changing habits of American workers dictate that businesses provide certain amenities with a result of more productivity.For example, with more women working, many industrial park developers would be wise to have a day care center. And with physical fitness so important, jogging paths or a workout area would be a bonus.

Other ways industrial parks can attract businesses is by providing attractive landscaping, sculpture, works of art, tennis courts, golf facilities, training centers, hotels, restaurants, retail shops, good signs, conference facilities, heliports, fountains and small lakes.

Eicher said he is concerned about the large amount of American assets being purchased by foreigners and wondered out loud what type of society there will be in 15 years if the trend continues.

Another speaker at the combined meeting of the Utah Chapter of NAIOP and the Utah Economic Development Corp. was Sid R. Peters, national executive vice president. He said a school system is the barometer of a city and good schools weigh heavily in corporate decisions to relocate or expand their operations.

Peters said teachers and school board members play an important role in shaping a community's attitude and they also are important in convincing people that education is important to a a healthy business climate.

People are living longer and coupled with the birthrate, there will be 265 million Americans by the year 2000. That means more jobs for people to provide the products and services for the expanded population, he said.
