The site has an existing storm sewer draining through the center of the lot to the lake. The existing storm sewer system is failing with respect to settled pipe sections and areas where pipe joints have separated. Caliber Builders proposes to relocate the existing pipe along the east lot line.Final lot grading will include a swale centered over the pipe to provide emergency overland drainage should the pipe become plugged. We have the following comments with regards to engineering matters: • The proposed design appears to improve the situation by replacing an aging and deteriorated storm sewer system. • We recommend that the applicant install a skimmer structure at the pond outlet south of the railroad tracks to prevent debris from entering the pipe. • Drainage and utility easements should be provided 5-feet wide over the pipe along the rear lot line and 10-feet wide over the pipe along the east lot line.No above ground structures or vegetation shall be permitted within the easement areas. • All manholes should have watertight castings. • rinai building elevations and site grading si�ali coniorm io the approved pians. • Silt fence should be installed inspected and approved by the city prior to any further work on the site. If you have any questions please call me at (651) 604-4863.
