Capital Hill PUD Page 54 of 67 <br />Planned Unit Development Application - Tentative Stage - Written Statement <br />March 3, 2017 Revised:June 19, 2017 <br />(b) A safety island of not less than 22 feet of full height curb shall in all cases be <br />provided between access connections under one ownership. <br />There is only one access connection. Therefore, this criterion does not <br />apply. See answer to (a) above. <br />(g) EC 9.6750 Special Setback Standards. <br />(2) Special Setback for Streets. <br />(a) A lot or parcel of land in any zone adjoining an arterial or collector street that is not <br />improved with curb, gutter, sidewalk, street lights and street trees shall have a special <br />setback line.... <br />Capital Drive is classified as a local street. The site does not adjoin an arterial or collector <br />street. <br />(3) Special Setback for Utility Easements. A lot or parcel of land in any zone for which there is a <br />planned utility easement, or where extension of public infrastructure has been identified <br />through long-range infrastructure plans or the design of existing infrastructure, shall have a <br />special building setback line to allow for the future easement. <br />There is no planned utility easement on this development site nor has extension of public <br />infrastructure been identified through long-range infrastructure plans. No special setback is <br />required to allow for a future easement. <br />(h) EC 9.6775 Underground Utilities. All new on-site utilities shall be placed underground if there is a <br />utility-owned structure immediately adjacent.... <br />All new on-site utilities will be placed underground. <br />(i) EC 9.6780 Vision Clearance Area. Development sites shall have triangular vision clearance areas <br />on all street corners to provide for unobstructed vision consistent with American Association of <br />State Highway and Transportation Officials (AASHTO) standards. <br />Vision clearance triangle areas will be provided on all street corners to provide for unobstructed <br />vision, consistent with AASHTO standards. See Site Plan for location of Vision Clearance areas.. <br />Q) EC 9.6791 through 9.6797 regarding stormwater flood control, quality, flow control for headwaters <br />area, oil control, source control, easements, and operation and maintenance. <br />EC 9.6791 Stormwater Destination. <br />Stormwater from the site will match pre-developed drainage patterns by incorporating various <br />techniques due to insufficient stormwater infrastructure for connection within a reasonable distance <br />to the site. Some areas will use underground detention tanks for flow control, while others will use <br />level spreaders and bubblers. The development will also incorporate pervious pavement in some <br />locations (namely Capital Drive) as an impervious area reduction technique. <br />EC 9.6792 Stormwater Quality. <br />Stormwater quality will be met by incorporating mechanical treatment devices to the new <br />impervious areas created by the private roadway. There is insufficient space for vegetated filtration <br />facilities due to the nature of the slopes on-site. The mechanical treatment devices in combination <br />with the underground detention tanks will provide sufficient treatment to meet the City's stormwater <br />quality requirements. The pervious pavement improvements to Capital Drive will sufficiently meet <br />the storm water quality requirements as well. <br />See Stormwater Management report. <br />EC 9.6793 Stormwater Flow Control (Headwaters). <br />The site is located above elevation 500 triggering the need to meet flow control requirements for a <br />headwaters area. As noted earlier, Stormwater from the site will match pre-developed drainage <br />patterns by incorporating various techniques due to insufficient storm water infrastructure for <br />Schirmer Satre Group • 375 West 4 m Avenue, Suite 201, Eugene, OR 97401 • (541) 686-4540 <br />
