Both lots will gain access to Watertown Road via a shared driveway in proposed <br /> Outlot A. Lot 2 shall have no separate access to Watertown Road. <br /> 9. The property contains a creek which flows through an extensive wetland system <br /> upstream of the property. The Orono Surface Water Management Plan indicates , <br /> that the Normal Water Level for the large wetland basin just to the north of the <br /> properly is elevation 963.5', with the High Water Level (100-year flood level) <br /> at elevation 970.4'. The top of the bank of the channel at the constriction area <br /> in Lot 1 is at approximate elevation 968.0', and closely matches the delineated <br /> ' wetland boundary. Per the recommendation of the City Engineer, the OHWL for <br /> setback and lot area calculation purposes for the property should be established <br /> at the wetland boundary elevation of 968'. The proposed driveway crossing will <br /> include a culvert which has been sized to meet all anticipated stormwater <br /> demands. However, to ensure that no upstream homes are flooded if the culvert <br /> � plugs, the City Engineer has indicated the top surface of the driveway crossing <br /> should be lowered from elevation 973.0' to 972' to allow for an open channel <br /> overflow that will be 2' lower than the lowest floor of the upstream residences <br /> (974' min.). The culvert should be an arch RCP to allow this reduction in height. <br /> , The RFPE, i.e. the minimum floor elevation for any building, should be <br /> established at elevation 974'. In proposed Lot 1, based on the topography and <br /> site plan submitted by the applicant, neither the buildable area nor the septic <br /> sites will be impacted by floodplain and OHWL elevations. <br /> 10. The creek driveway crossing will require filling within floodplain as well as <br /> within the wetland. A number of variances are required to allow the creek <br /> crossing. The specific issues with the driveway which require variances are: <br /> a) Portions will be within 75' of the OHWL of the creek where no <br /> hardcover or grading is allowed except by variance per Section 78-1286; <br /> b) Portions will be within a delineated wetland or within 26' of the wetland, <br /> . where no grading or filling is normally allowed. <br /> Grading and filling in or near a wetland, and crossing of the creek, are also <br /> subject to WCA regulations administered for Orono by the Minnehaha Creek <br /> Watershed District. <br /> s <br /> Page 3 of 9 � <br />
