1. The survey does not comply with City Standards. <br /> a. Retaining must have top of wall and bottom of wall elevations called out(#23). <br /> b. Service utilities(water,gas,electrical, and sanitary sewer with invert elevation at connection point) <br /> (#14) <br /> c. Drainage patterns are not indicated with arrows(#21). <br /> d. Drain tiles are not indicated. I could not find the outlet for all of the drain tiles that the downspouts <br /> feed into. (#9) <br /> e. Driveway slope is not indicated (#22) <br /> 2. The approved plan had a drainage the and swales on the south side of the home. These are not shown in the as- <br /> built and do not appear to be present on the site. Were these constructed and in accordance with the <br /> comments provided in November of 2014? If not why not? There does appears to be a swale at the west end of <br /> retaining wall "P" directing run off to the south and into a depression on the neighboring property near the <br /> utility pole. Photo Attached (looking south from driveway)This must be remedied either with that originally <br /> planned drain the or some other mechanism to capture the hard cover run off and direct it somewhere other <br /> than the neighboring property. <br /> 3. Was the move of the retaining wall into the County ROW approved by the county? Normally they require 15ft <br /> from the fog line. The retaining wall is actually—7ft from the fog line. This is a county issue but one the <br /> homeowner will want to ensure has been approved to avoid future issues. <br /> Adam <br /> From:Adam Edwards <br /> Sent:Tuesday, February 23, 2016 3:46 PM <br /> To:Christine Mattson<CMattson@ci.orono.mn.us> <br /> Cc: Melanie Curtis<MCurtis@ci.orono.mn.us> <br /> Subject: RE: 1070 Tonkawa Road/#2014-01157(new house)&#2015-00809(detached accessory structure and <br /> driveway relocation) <br /> Chris, <br /> I've reviewed the as built and offer the following comments: <br /> 1. The survey does not comply with City Standards. Retaining must have top of wall and bottom of wall elevations <br /> called out(#23).Any walls over Oft will need an engineered design. <br /> 2. The as-built depicts several variations from the approved site and grading plan, approved on 17 Jul 1015: <br /> a. There is a retaining wall shown on the north side of the home along the property line. It appears to cross <br /> the property line at the western end. Was this approved by the encroached upon property? <br /> b. The drainage pattern/swale shown on the approved plan to the north of the structure is not depicted on <br /> the as-built. <br /> c. A retaining wall is depicted on the south side of the driveway. <br /> d. The approved plan had a drainage tile and swales on the south side of the home. These are not shown <br /> in the as-built. Were these constructed and in accordance with the comments provided in November of <br /> 2014? If not what was done to establish a drainage pattern that does not increase run off onto the <br /> neighboring property. <br /> e. A retaining wall is depicted around a concrete pad on the north side of the house. <br /> 2 <br />
