Page 1 of 2 City Of Pequot Planning &Zoning From: Tim Houle[Tim.Houle @wsn-mn.com] Sent: Friday, April 20, 2007 8:29 AM To: dbittner @pequotlakes-mn.gov Cc: Mike Rude Subject: Pequot Lakes-Stormwater Runoff-3588 Fox Lane Dawn, As we discussed last night, we had given you a brief verbal report on the above topic at the April City Council Meeting, but here is a follow-up written note. While there was snow cover from a recent snowstorm on the ground at the time of our site visit, it does appear that the construction and landscaping/turf establishment of the new home is not yet complete. Generally, once vegetation is established, many runoff problems that were present with barren sand/soil are taken care of. We did not have before contours/elevations to compare the new situation to, so we cannot say a lot about if water runoff has or has not been negatively redirected. It did appear that, generally, the houses were slightly higher than the surrounding yards (which is obviously good from what I consider one of the more important considerations in a situation like this, i.e. a structure flooding/water damage perspective). There did still appear to be low spots out towards the road to allow for infiltration (see my vegetation comment above). Obviously, in spring snowmelt/thaw conditions, there will be times of standing water. Some years are worse than others. As we have told folks in all the Cities we work with, we can look at these situations. They generally fall into 3 categories: 1) It is just regular snowmelt and it will be gone in a week or two. 2) Yes, the ponding is going to cause a problem, but you are at the low spot. We/the City could try to make the low spot bigger to hold more water and/or it may have to have some periodic pumping if it is threatening a structure. 3) Yes, the ponding is going to cause a problem and the City could spend X dollars on putting in drains, pipes, culverts, etc. to address this one time snowmelt situation. Not that I have kept a tally, but many fall into the first category. , Dawn, when vegetation starts to get established and (if) you want us to maybe look at this again, let us know.
