Given the wet conditions last fall and this spring, the street drain tile has been running constantly, keeping the swale wet, even after a week without rain. The lake level has also backed up into the swale, but the main concern is the water standing in the swale on the upstream half. • The ponding in the swale is due to a lack of grass growing in a few locations. These areas were reseeded a couple times in 2010 when the swale was actually dry, but the seed most likely washed away with a rain. If these bare areas had grass growing in them, the water would not pond in the swale, but would slowly flow to the lake. If these wet conditions continue, the swale can be expected to have water feeding it from the drain tile in the street and from the back yards south of your property. Under typical conditions, the swale will be dry within a few days. • There was also a question of whether or not the swale even drained from the pipe to the lake. Don and I surveyed the swale and it has 1.2' of elevation difference from the pipe to the lake, which was anticipated with the design. This equates to about 1.5% grade. • Another question was can the swale will withstand a larger than normal rain event. The answer is yes, it was designed based on a 10 year rain event, which statistically should only occur once every 10 years, and is larger than average. • There was a concern about erosion at the top of the hill due to construction work on site. I believe it has significantly improved from the existing conditions prior to construction (See Photo). I am hesitant to disturb it again given that it was restored a couple times by the contractor in order to get it stabilized. • In order to reduce the likely hood of water ponding in the swale, the City will have the Contractor raise the end of the pipe 4 to 6 inches in order to improve the slope of the swale from the end of the pipe, to a point half the distance to the lake. The contractor will add topsoil, use the reinforced turf mat and sod to complete the restoration. We all agreed that the portion of the swale from the lake, half way to the pipe appeared to be fine as is. • The City is waiting for the easement documents to be signed by you so that the easement can be filed with Hennepin County. It is preferred that the easement documents be signed and delivered to the City prior to the remaining restoration work taking place. We understand that you are using the easement as leverage to get the restoration complete, but given that the City has been cooperative throughout this entire situation, we are not sure that leverage is necessary. • Given the wet conditions, it may still be a month, or even two, before the work can be completed. I will be in contact with you regarding the timeline. Feel free to give me a calf or email if you have any questions. Thank you, 1
