Review File: Rabbit Meadows <br />Final Plat Application <br />Engineering Review <br />Page 2 of 2 <br />culvert proposed to cross 171' Avenue. The total area of impervious surface must be reviewed. <br />The driveways and street side of the houses will drain to the pond. It appears the current number <br />only covers the new streets. <br />A permit from the Lower Rum River Water Management Organization (LRRWMO) will be <br />required. <br />Utilities: All lots are proposed to be served by well and septic. The septic design report must <br />show the locations of the borings performed for design of the septic systems. <br />Streets: The street section details must call out Ramsey modified Class 5 aggregate base with <br />the gradation shown. Ramsey standard details must be used. <br />SWPPP: A copy of the approved NPDES permit must be submitted to the City. The area of <br />new impervious surface must be reviewed as noted under grading and drainage. The SWPPP <br />states two (2) infiltration ponds will be constructed. The grading plan shows one sedimentation <br />retention pond. Copies of the SWPPP inspection reports must be provided to the City on a <br />regular basis. These reports will be retained by the City as part of their MS4 permit. Changes to <br />the SWPPP must also be reported to the City. <br />
