DEC-09-1998 lB:3t:1 BRW 612 . 37121 1378 P.I2I2/04 Mr. Brian Fritsinger .. December 9, 1998 Page 2 . 1) Storm Water Pond Relocation: The original plan prepared by Howard R. Green detailed a stonn water pond adjacent to an existing wetland located south of 13th St. NE. This location had not been agreed to by the property owner prior LO the project letting. As a result of negotiations with the property owner, a new location for the pond was selected betwcen the Minnesota Commercial Railroad spur line and 13th Street N.E. This location required additional excavation of soils since the general surface elevation was higher than the original pond location. The new location places the pond in an area under the existing NSP easement in the northwest corner of the site and therefor improves the marketability of the property over the original pond conJiguration which was situated more central to the property. All acceptable soils excavated from the pond (approximately 65% of the total) were utilized for backfil I of the sanitary sewer trench and road embankment construction. The contractor agreed to perform the additional excavation at the original contract unit price. The cost of this work is approximately $48,000.00. 2) Watermain Related Work: a) The original plans included the construction of a 12" diameter watermain along 14th Street to serve the new development and enhance fire flow capacity in the northwest portion of the City. After reviewing the existing city watermain network it . became apparent that a 600 foot section of existing 8" watennain located along an easement to the southeast of the Welsh development was not included in the project for upgrade to 12". This section ofwatennain would be sandwiched inside an otherwise continuous 12" trunk waterrnain loop. This situation was discussed with city staff and the staff agreed with the City Engineer's recommendation to upgrdde the existing watermain to 12" diameter. The cost of this work is approximately $16,500.00. b) The original plans did not address an existing hydrant located in the proposed Gateway Court cuI-de-sac. The existing hydrant was salvaged and a new hydrant was installed adjacent to the new roadway. The cost of this work is approximately $5,500.00. 3) Saoitary Sewer Related Work: a) The original plans did not include provisions for connecting the existing ATS sanitary sewer to the new trunk sanitary sewer. The plans were modified to include a 24 foot deep manhole with outside service drop connection. The work was paid for under existing contract items. The cost of this work is approximately $4,300.00. b) The existing sanitary sewer pipe at the downstream connection of the new trunk sewer was determined to be sagging and holding sewage. The contractor was directed to modify the proposed connection to avoid the existing sagging pipe. This lJ,\WpOOCS\l\Jt.DJDIIlftl.,\OATmVA.'Y\l."m.a.WGI#4.MI!M .
