Iowa Community Forestry Survey, 2010
The Iowa Department of Natural Resources Forestry Bureau and Trees Forever engaged CD-DIAL to conduct a survey of Iowans involved in urban forestry projects. Via an online survey, respondents were asked to evaluate the implementation of community forestry projects, challenges to program delivery, and urgent needs. The results were presented to the natural resources and agriculture committees of both the Iowa Senate and House of Representatives.
Story County Health Needs Assessment
In collaboration with the ISU Nutrition and Wellness Center and the ISU Center for Survey Statistics and Methodology, CD-DIAL conducted a comprehensive health needs assessment for the Story County Community Coalition. The methodology included focus groups, printed surveys mailed to a random sample, and an online survey open to the public.
City of Ames Residential Satisfaction Survey
Since 2009, CD-DIAL has conducted a residential survey for Ames to evaluate the services it provides to citizens and to identify areas in need of improvement. A survey was mailed to randomly selected respondents. To obtain a better representation of ISU students, the survey was conducted online.
Clay County/City of Spencer Needs Assessment
CD-DIAL worked with a local needs assessment steering committee representing the City of Spencer, the Clay County Community Foundation, and the Clay County Local Housing Trust Fund. CD-DIAL designed, printed and mailed surveys; collected responses; and analyzed the data.
Buchanan County Conservation Board 2010 Needs Assessment
CD-DIAL assisted the Buchanan County Conservation Board (BCCB) to conduct a survey to inform the board as it developed its long-term plans for increasing the quality of life through programs of conservation and education. This needs assessment is a follow up of a previous assessment done in 2005.
The methodology for all of these projects included follow up with postcards, phone calls, or e-mail.
