Hi,
Kelly, Thank you for removing the concrete today. I appreciate it.
Craig, The concrete was actually spilled in front of me during the pour. Luckily the creek was dry at the time, however I asked the workers on site to clean it up and it was not done.
As for erosion control practices. It may be an annoying part of the process of construction, but it is a requirement and must be maintained. The silt fence on the south side of the creek has been down for quite a while. Again I understand season has been dry with little to no rainfall up to now, but moving forwards that will not be the case.
Silt Fence is the correct BMP to use (if installed correctly, trenched and backfilled) to protect the creek during construction activities. Waddles or coir logs can be used in addition to silt fence. Straw should also be placed on any open bare dirt soil.
Moving forward with the construction of the structure, as a suggestion I encourage you to look into addition ways to detour pedestrians off the structure until complete. The City choses to rent traffic barricades, chain link fencing or use concrete blocks. This measures help protect the property owner from possible claims. I understand that it is a struggle to keep pedestrians out of the construction area.
Thanks for your cooperation,

Thanks for your update, Jennifer. We appreciate your concerns, and will do everything we can to address them.
The concrete contractors didn’t mention anything to me about concrete spilled in the creek and, honestly, I didn’t see any such concrete despite having gone to the site several times since then. However, after getting your e-mail, Kelly went down to the site today, searched the creek, and removed a piece of concrete she found in the creek bed. After having previously consulted with DEQ, Division of State Lands and the Army Corps of Engineers, clean concrete not within the portion of the creek between the high water marks on both sides is not regulated by these agencies, so would not be a concern.
You shouldn’t find any more concrete within the high water marks or tops of the banks on either side of the creek. If you do, please let us know, and we’ll make sure it’s removed.
Regarding the silt fence, we will take care of that too. We have been sending people out to the area almost daily to keep barriers erected, including signs and caution tape. However, we have been noticing evidence of a high amount of bicycle and pedestrian traffic through the site, despite the “no trespassing” signs and barriers. (This shows how much this facility is needed.) The silt fence is doing fine in most spots, but is prone to being damaged by wind and trespassers.
Unfortunately, our group (and I expect the city too) does not have the resources to post a 24-hour guard to make sure people don’t cross through the site and knock down the silt fence. As we keep putting up the silt fence and barrier tape, trespassers keep knocking them down. However, there are alternative means of sediment control that are effective, ODOT-approved, and much less likely to be damaged by either wind or foot traffic. If you would allow us to use one of those in the areas that people keep knocking down, it would be very beneficial for the environment and the future safety of our residents.
Of course, once the creek fills, people will stop traversing the area until the water level falls again. Also, once the bridge is erected, people will stop knocking down the silt fence. The bridge has been fully manufactured and delivered. We are ready to install it as soon as the concrete has cured to 28 days, and has passed Carlson Testing’s pressure tests. (You should have already received results of the 7-day pressure tests. If not, please let me know, and I will re-send them.)
We will continue to work as diligently as possible to address your concerns. Thank you for bringing everything to our attention.
Best Regards... Craig

Hi,
I stopped by the site late yesterday evening and found a few concerning items.
The silt fence that was removed to pour the concrete bridge footings and stem walls was not reset. The concrete that was spilled into the creek bank was not removed as I had requested. Although the property is not dedicated to the City, construction requirements require erosion control to be maintained. Any concrete spillage near a creek can be a concern by DEQ.
Please trench and reinstall the silt fence to protect Bear Creek from any possible sediment erosion and please remove the concrete from the creek within the next 24 hours. Please call if you have any specific questions.
Thank you,
