� <br /> 15-3763 t <br /> July 16,2015 <br /> Pape 6 of B <br /> The stormwatex management system has been reviewed by the City Engineer (see Ezhibit E for <br /> additional comments regarding stormwater management). All stormwater management sha11 be <br /> subject to MCWD reqwirements and approvals. <br /> Septic Systems & Weus <br /> The properties will be served by private on-site septic systems and private wells. Fu11 soil testing <br /> and preliminary system designs have been completed for 5-bedroom hames. However, staff is <br /> concemed that a majority of the lots (2-5-b-7) appear to have their septic sites located right up to <br /> the minirnum wetland setback and in at least one instance, less than the required SQ feet. Further <br /> review of�iese sites is warranted and relocation further from the wetlands may be appropriate <br /> where feasible. <br /> Wetlands on Site and/or Impacted <br /> The wetland boundary delineation report has been approved by the MCWD. No wetlands are <br /> proposed to filled. Buffers of 40' and 50' are depicted on the plans; however, if 75' buffers are <br /> ultinnatety required, that could be a significant impact on the site layout. The City will require a <br /> Conservation and Flowage Easement over each of the wetlands as well as impose standard <br /> wetland setback requirements; in the case of a11 wetlands on this site, the required structure <br /> setback w�ill be 1 Q feet landwazd of the edge of the wetland buffers. <br /> Woodland �mpacts & Coaservation Desi�gn <br /> The developer has submitted a Conservation Design Report and Master Plan (please review <br /> Eghibit C, especially pages 1-5). In general, the development will maintain the rural character <br /> consistent with the surrounding neighborhood, Applicant has arranged the site to preserve three <br /> of the four noted significant tree stands; the fourth, comprised of introduced conifers near the <br /> south end of the site around the existing residence, will be impacted by road construction. <br /> Wetlands and drainage patterns will be maintained, and the views into the site will not be <br /> significantly disrupted. A vegetation management plan spells out a variety of actions to be taken <br /> with regard to wetland buffer areas, buckthorn, and reed canary grass. The suggested Master <br /> Plan management guidelines will be incorporated in to the development agreement and <br /> covenants to assure adherence. <br /> City Engineer Commen�s <br /> The City Engineer has provided a number of general and detailed coxnments (Exhibit E) which <br /> the developer is advised to review and address as tb.e preliminary and final plat move forwazd. A <br /> brief summary of his comments includes: <br /> General: <br /> - Show proposed well locations <br /> -Define proposed entry monument parameters <br /> -Provide a removals/demolition plan <br /> - Submit draft development covenants <br /> - Submit preliminary Iandscape plan <br /> - Should revegetate Outlot A of Tamarack Hill after driveway abandaned <br /> - MCWD approvals required for various aspects of project <br /> -NPDES Permit will be required <br /> -Maintenance Agreement required for stormwater systems <br /> Stormwater: <br /> -Volume retention standazds must be met <br /> -In calculations,revise to indicate ultimate conditions <br />
