Has your agency installed porous asphalt pavements, either open-graded friction course or full-depth porous asphalt? If so, we are asking for your assistance in gathering detailed information about your project(s). Information provided will be incorporated into a Porous Asphalt Guidebook that we are developing for Multnomah County and City of Gresham. Upon completion, this guidebook will be available for download and may be of use to your agency for future porous asphalt projects. We aim to have the guidebook completed in late September or early October.

Currently, we are only interested in porous asphalt projects, not pervious concrete, permeable pavers, or any other form of permeable pavement. If you have multiple projects installed, please consider providing information for at least three of your projects. While the projects you choose to share with us are your choice, at a minimum, we suggest providing your oldest, newest, and highest traffic-volume projects. We understand that the information crosses functional boundaries and will require input from several staff members. Hopefully, you can coordinate internally to provide comprehensive information.

Please complete as many items on the form as possible before submitting the form. If you do not have the information for a specific question, respond DNK or leave it blank.

**You do have the option of "SAVE & RESUME LATER". If you choose this option at the end of the form, you will be provided a unique URL back to your form. BE SURE TO COPY AND SAVE THIS URL You may share this link with members of your team.

If you know of another jurisdiction that has installed porous asphalt, please feel free to forward them a link to this form.
