If selecting an infiltration or filtration facility to treat the <br />stormwater runoff from the public street, the facility can be <br />sized to also treat the stormwater runoff from the one and <br />two family dwelling lots or parcels adjoining the public street <br />based on full buildout of those lots or parcels. <br />2. If using a mechanical facility to treat the stormwater runoff <br />from the public street or if the infiltration or filtration facility <br />is not sized to also treat the stormwater runoff from the <br />adjoining lots or parcels at full buildout, all lots or parcels <br />created by the land division application shall comply with <br />EC 9.6792(3)(d)-(g) at the time of development permit <br />application. <br />Response: This application does not involve the construction of a public street, but will connect to <br />the existing stormwater facilities in Brackenfern Road that were constructed with the East <br />Ridge Village PUD, and the facilities presently under review for construction in Deerfern <br />Road that were planned and designed to accommodate runoff from area Lot 46 of the <br />PUD proposed to be modified by this application as discussed in the Preliminary <br />Stormwater Report in Exhibit F. This standard is met. <br />(c) For land use applications proposing construction of a private street <br />or shared driveway, stormwater quality facilities to treat the runoff <br />from the proposed private street or shared driveway shall be selected <br />from the Stormwater Management Manual and shall be based on the <br />following priority order: infiltration, filtration. <br />1. An infiltration or filtration treatment facility to treat the <br />stormwater runoff from the shared driveway or private street <br />can be sized to treat the stormwater runoff from the <br />proposed one and two family dwelling lots or parcels that <br />adjoin the shared driveway or private street based on full <br />buildout of those lots or parcels. <br />,~/►L7 East Highlands Lot 46 - City of Eugene November 2021 <br />PUD Modification, Cluster Subdivision, Property Line Adjustment and Page 14 <br />Slope Easement Vacation <br />
