The proposed stormwater <br />management system has been designed to protect life and property from <br />potential flooding and will be constructed according to all adopted plans and <br />polices pursuant to EC Chapters 6 and 7 and also City of Eugene's Stormwater <br />Management Manual. Since there is no existing stormwater system <br />available and due to the existing conditions of the development site, <br />infiltration is unadvisable. Destination of the stormwater from the <br />development site, after treatment, will be along the east side of the property <br />and will slowly sheet drain on to the adjacent city property. Flow from the <br />site is reduced to pre-development flow and is dispersed using rip rap; no <br />increase is proposed. This destination was agreed upon in a subsequent <br />meeting on January 30th, 2013, by Neil Bjorklund with the city's Public Works <br />department. If deemed necessary, as a supplement, the PUD shall comply <br />with the City's Level Spreader Design requirements, including complying with <br />proper installation guidelines. For further evidence and analysis showing <br />compliance with this criterion, please refer to Planned Unit Development, <br />Tentative Plan permit application filed concurrently with this application. <br />(Policy G.10) Eugene and Springfield and their respective utility branches, <br />EWEB and SUB, shall ultimately be the water service providers within the <br />UGB. <br />Findings: The development proposes EWEB to be the main service provider <br />and is already working with the Eugene Water and Electric Board planning for <br />facilities. <br />(Policy G.12) Ensure that water main extensions within the UGB include <br />adequate consideration of fire flows. <br />Findings: The proposed development will comply with fire flow <br />requirements as recommended by EWEB and the Fire Marshal and will <br />provide adequate pipe sizing thusly. <br />(Policy G.16) Consider wellhead protection areas and surface water supplies <br />when planning stormwater facilities. <br />(Policy G.17) Manage or enhance waterways and open stormwater'systems <br />to reduce water quality impacts from runoff and to improve stormwater <br />conveyance. <br />(Policy G.18) Include measures in local land development regulations that <br />minimize the amount of impervious surface in new development in a manner <br />that reduces stormwater pollution, reduces negative [effects] from increases <br />in runoff, and is compatible with Metro Plan policies. <br />Willamette Greenway -June 14, 2013 Page 13 of 20 Oakleigh Cohousing WG 13-0001 <br />1348 <br />
