Web Form: The storm pipe/drain does not appear to have sufficient capacity to handle flash flood events. Storm water from the neighborhood overflowed from the street, and then flowed across the neighbor's driveway and down the slope into our property, flooding our crawl space. Last night there was literally a small river of water running aside and into our house, moving so fast that I could not safely walk outside until the rain subsided. We need an engineer to evaluate the current drainage system, in particular the capacity of the storm pipe and culvert that runs directly between our property and the neighbor's. We can make some mitigating improvements on our own property, but we really are not equipped to handle the sheer volume of stormwater from the entire neighborhood during very heavy periods of rain like we saw last night. I took some videos during the flood that we can send as well.

Please have the inlets in this drainage area cleaned. That would include the inlets at the intersection of 11th St/Blaire and on up Blair Ave towards Tri-North.
Alex, Thanks for letting us know about the drainage issue you experienced. We visited the site and I ran a calculation to confirm the pipe has adequate capacity for the design storm. The calculation showed it would have plenty of capacity. I do believe that the inlets probably didn't have the capacity during the recent rain events because of debris blockage. I've put in a request for inlet cleaning in this drainage area. I'd also like to share that our storm sewer is designed for the 10-year storm event and if a larger storm event occurs there will ponding in the road and curbs in roadways at lowpoints will likely overtop. For homes near low points it is important for property owners to provide a safe overflow route for the water that won't cause substantial property damage. We will continue to monitor this area during rain events.
