City of Spokane Valley, 10210 East Sprague Avenue,Spokane Valley, WA 99206,
LBarlow@spokanevalley.org.Ref: Project Name: Painted Hills PRD - 2015-0001Proposal Description: A planned
residential development with 300 single family homes, 280 multifamily units and aneighborhood commercial center.
Questions:1. Who will be performing Operational and Maintenance of structures in and around the
development. I.E trash racks, pipe openings, swales. 2. Appex. E: "Pipe openings clogged by debris during a flood event". "Vegetation in and near
the ditch that enters the pipe is non-woody and would not contribute a measurable amount ofdebris." In my 10+ years of working in and around CSO tanks and sewer lines I have
witnessed many different objects blocking control gates and racks. Everything from treebranches to large rocks. It does not depend on vegetation in the local area of the rack-it's more
dependent on the items upstream in the Chester Creek Watershed and the amount of energyforced by heavy rains. This was recently shown by a microclimate downpour in the north
Spokane area within the last year.Because of these reasons and other concerns that will be addressed more fully, I would like to
request a public hearing on this project's DEIS.
Thank you,Lance Verity (PC385)
