1976: IV-26) . The major airports and heliports used by 

 offshore operators are shown in Figure 1.10. While the 

 facilities at Dulac , Grand Isle, and Leeville are strictly 

 heliports , some of the other airports , such as Houma-Terrebonne 

 and Nev7 Orleans Lakefront, also contain heliport facilities. 

 Seaplane bases, which are used primarily for onshore oil 

 and gas operations in the wetlands are not included. ( Air- 

 ways Engineering Corporation, 1976: IV-26). 



Many Louisiana highways are used by offshore operators 

 (Figure 1.11). While most of these highways are not used ex- 

 clusively, nor even primarily, by the offshore oil and gas 

 industry, they do function as part of industry's transportation 

 network. This can result in increased maintenance work and 

 traffic control, or, in some cases, may necessitate widening 

 of a roadway or even construction of a new roadway. For example, 

 in Lafourche Parish, Louisiana, where the oil industry has had a 

 substantial impact, a new road, Louisiana 3090, was needed to 

 provide land access to Port Fourchon , and Louisiana 1, a two- 

 lane highway, is being relocated as a four-lane facility for at 

 least part of its length (Larose-Golden Meadow section) 

 (Mumphrey et_al. , 1976: 313, 316). 



The need for vocational school programs concerning oil and 

 gas production, -and offshore service industries such as water 

 transportation and ship and boat building and repair repre- 

 sents another type of support facility. The vocational 

 schools, of course, do not exclusively serve the OCS- 

 related industries, but there is a need for vocational schools
