Has the development team considered routing the sanitary sewer due south from SAN MH 3 <br />towards the existing sanitary sewer system? This would require an easement through private <br />property but would be much less complex. I ask this due to the complexity of the comments that <br />will follow if we maintain the existing sewer alignment (Zone A Floodplain shown below in blue <br />hatching). A change to a southern alignment could be most cost-effective and permit friendly. <br /> <br /> <br /> <br />3. The current sewer alignment/profile runs through a designated Zone A Floodplain and results in a <br />berm (net fill) within the floodplain. As such, the developer will need to do one of the following: <br />a Perform a hydraulic study to show there are no impacts to the floodway or flood elevation <br />b Create a No Net Loss condition by removing an amount of material from the floodplain <br />equal to the amount of fill being placed <br />
