<br />Mr. Steve Ach <br />March 22, 1994 <br />Page Four <br /> <br />e) <br /> <br />· SHEET C3.4 <br /> <br />The proposed storm sewer line and easement across the school property from <br />the pond at the southwest corner of the plat to Freeport Avenue must be <br />shown. <br /> <br />The watermain along Freeport Avenue will be an 8-inch line from the south <br />plat line to School Street, rather than the 16-inch line shown.. <br /> <br />· SHEET C4.1 <br /> <br />A landing area should be provided where Freeport Avenue intersects Jackson <br />Avenue. <br /> <br />The driveway on the south side of Freeport Avenue at station 33+50 needs <br />the grades to be adjusted to allow for a flatter landing area. <br /> <br />The driveway on the west side of Freeport Avenue at station 27+75 needs a <br />high point at the right-of-way line to keep the Freeport Avenue drainage in <br />the street. <br /> <br />.,]). <br /> <br />Catch basin' #17 rim elevation is shown as 935.08; this should be 936.08. <br /> <br />Drainage over bituminous surfaces should have a minimum of 1 % with a <br />recommended grade of 1.5 % to 2 %. Several areas are at or below the <br />recommended 1 % minimum grade. Some areas of concern are as follows: <br /> <br />Drainage going east from in front of the Cub Foods store and the <br />buildings to the north. <br />Drainage from islands east of catch basins #39 through 42 to the catch <br />basins. <br />Area in loading ramp on north side of Cub Food store to catch basin <br />#72. <br /> <br />Catch basin #71 is at high point, rim elevation should be checked. <br /> <br />· SHEET C4.2 <br /> <br />Why is manhole 64A necessary? Could manhole #64 connect directly to <br />manhole #63? <br /> <br />e) <br /> <br />TJM:tp <br />230/152-2212.mar <br />
