Is the minimum size of one-half to one-third acre, for wooded-site development, a reasonable guideline? Is it risky to try to get away with smaller lots? 2. How can we motivate the appropriate people, to make sure that the correct procedures are followed? 3. When is it better to remove a tree, before construction begins, than to leave it standing? 4. How valuable are trees? Are some trees more valuable than others? 5. What persons or agencies are the most reliable and best able to provide help with specific problems relating to trees and wooded-site development? 6. How likely are the oldest and largest trees to suffer damage during construction? 7. Why is it a good idea to locate roadways so as to do the least damage to valuable stands, and to minimize cuts and fills? 8. Are most of the principles outlined in this program standard procedure? If some are not, should they be adopted? 9. Should these principles be incorporated as part of state law? 10. To the developer, what are the advantages and disadvantages of following the proper procedures for development in wooded areas? 12-4 ------- Review Answers Questions 1 1. 5. 9. 1. 4. 6. 8. a. c.

OBJECTIVE The objective of this audiovisual package is to pro- mote better understanding among erosion and sediment control specialists as to: - the roles of the foreman and inspector. - the responsibilities of the foreman-inspector team. - the concept of "social control" or enforcement" PREPARATION FOR PRESENTATION This audiovisual package is designed both for self- study and for group presentation. For an effective smooth-running group presentation, plan well in advance. Have the audiovisual projector, the screen, and the seating set up. Have the workbooks ready for distribution. Before presenting the filmstrip, preview it and read the workbook so that you can have their contents clear in your mind and can answer questions. Previewing the film- strip also assures you that the audiovisual projector is working properly. Finally, prepare the audience. Explain the objectives of the audiovisual package. Describe the sequence of e- vents of the presentation. Tell them that there will be a short review quiz at the end of the program to help them discover how well they have understood the filmstrip. 13-1 ------- PRESENTATION The program can be viewed continuously. However, because of the quantity and detail of the information presented, it is suggested that you view it in sections. The projector and audio is pro- grammed to allow a fifteen second pause at review points. This will provide time to stop the projector for question and answer periods. Always make sure everyone understands each part of the program before going on to the next part. PROJECTOR OPERATION FOR AUDISCAN EQUIPMENT ONLY To operate the Audiscan audiovisual projector in- sert the appropriate cartridge with the arrow up into the side of the machine. Turn the machine on using the Volume On/Off switch. Focus as desired. To restart the projector when it stops for workbook questions, push the start portion of the Program Hold/Start switch. Should the audio and visual por- tions of the filmstrip become unsynchronized for any reason, synchronization may be re-established by holding the Lock switch to the left and at the same time depressing either the Film Hold or Film Advance switch as appropriate. SEQUENCE OF EVENTS Welcome the group and prepare them as previously described. Tell them that a workbook will be dis- tributed. Add that it was prepared to expand the information in the filmstrips. Also, inform them of the built-in review periods. Show the program, Foreman-Inspector Responsibilities. Review the roles of the foreman and the inspector. Be sure the trainee understands the five responsibili- ties of the Foreman-Inspector Team. The trainee should also know the importance of social control or enforce- ment. 13-2 ------- IDEAS FOR DISCUSSION 1. Explain the "shared" responsibility of the foreman and the inspector. 2. Can the roles of the foreman and in- spector be viewed separately? 3. What is the best way to obtain a "working knowledge" of current prac- tices? 4. How do you plan your activities? 5. How essential is maintenance for effective erosion and sediment con- trol? 6. How important is it that practices meet design specifications as close- ly as possible? 7. How can problems still occur in the field inspite of the best planning and design? 8. Why do the inspector and foreman have to play the role of "amateur psychologists"? 13-3 ------- Foreman - Inspector Responsibilities WORKBOOK - ANSWERS Questions 1.
