Cost-Effective and Sustainable Road Slope Stabilization and Erosion Control (2012)

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

65 APPENDIX A Survey Questions A survey was developed to gather additional information from practitioners, scientists, contractors, and vendors on current practices, best practices, and emerging solutions that are used regionally, nationally, or internationally. The survey was cre- ated in Survey Monkey (http://www.surveymonkey.com/), an Internet-based survey tool that allows survey respondents to answer questions online. The survey asked participants to provide identifying information, followed by eight questions requesting information on the respondents’ direct experience with erosion control and slope stabilization techniques. The survey was distributed by e-mail to individuals identified in the literature review and by project panel members. Information gathered in the survey that was incorporated into this report includes resources, references, erosion control and slope stabiliza- tion techniques and tools, best management practices, useful points, and photographs. Survey responses aided in focusing the synthesis on the most frequently used road slope stabilization techniques that are cost-effective and sustainable. Survey Questions 1. Please provide the following information: Name ________________________________________________________ Company/Agency_______________________________________________ Address ______________________________________________________ City/Town ____________________________________________________ State/Province _________________________________________________ Zip/Postal Code ________________________________________________ Country ______________________________________________________ E-mail address _________________________________________________ Phone Number _________________________________________________ 2. How frequently do you use shallow or near surface road slope stabilization and/or erosion control measures in your job? …… Always …… Frequently …… Occasionally …… Never (If never, please describe your experience with road slope stabilization and erosion control below). 3. Please check the road slope stabilization and/or erosion control measures you have used. ……Water management plan …… Soil bioengineering …… Reinforced soil slopes …… Biotechnical slope stabilization …… Structural stabilization …… Surface and subsurface water drainage …… Erosion control mats/treatments …… Flattening failing/over-steep slopes …… Shallow structures …… Earthwork and/or terracing …… Shallow anchors

66 …… Anchored wire or mesh …… Pins and/or posts …… Buttresses or low-cost retaining structures …… Brush layering …… Live stakes …… Vegetated walls …… Vegetated reinforced soil slopes …… Geotextile (burrito) walls …… Low gabion walls …… Deep patch geosynthetic road shoulder reinforcement …… Hydro seeding …… Hand seeding …… Other (please specify): 4. Where do you use road slope stabilization measures? …… Embankments …… Road cut and fill slopes …… Culverts …… Bridges …… Other slopes …… Ditch cleaning or reshaping …… Other (please specify): 5. When considering a road slope stabilization or erosion control measure, how important is cost? …… Initial/short term—extremely important, important, somewhat important, not important at all …… Long term (including maintenance)—extremely important, important, somewhat important, not important at all …… Both short and long term considered together—extremely important, important, somewhat important, not important at all 6. When considering a road slope stabilization or erosion control measure, how do you factor in how environmentally friendly or sustainable it is in your decision-making process? …… Always …… Frequently …… Occasionally …… Never …… If considered please describe why (i.e., state mandate) 7. Can you provide examples of successful road slope stabilization measures you have used that were sustainable, envi- ronmentally friendly, and/or low cost? (If so, do you have drawings, sketches, or photos of these?) …… Yes …… No

67 If Yes, please provide up to three examples below. _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ 8. If you answered yes to the previous question, may we contact you for additional information and a possible follow-up interview? …… Yes …… No Contact information for follow-up interview (if you did not provide it initially). _____________________________________________________________ 9. Please point us to 1–2 relevant documents/publications or professionals that can benefit this project.
