(g) EC 9.6750 Special Setback Standards. <br />The applicant's plans show a 20-foot special setback from the north property line for future right- <br />of-way for Oakleigh Lahe. Public Works staff confirms that a special setback is not needed, based <br />on the right-of-way needs being exacted as a condition of development; refer to the findings and <br />conditions at EC 9.8320(5)(a), which are incorporated by reference. <br />(h) EC 9.6775 Underground Utilities. <br />To ensure compliance with this standard, the following condition of approval is necessary: <br />The final PUD plans shall note that all on-site utilities will be placed underground <br />consistent with EC 9.6775. <br />As conditioned, the development will comply with this standard. <br />(i) EC 9.6780 Vision Clearance Area. <br />This standard does not apply because the subject property is not located at a street intersection. <br />(j) EC 9.6791 through 5.6797 regarding stormwater destination, pollution reduction, flow <br />control for headwaters area, oil control, source control, easements, and operation and <br />maintenance. <br />1012 <br />In regards to EC 9.6791 Stormwater De_nihfition, Works staff confirms that on-site <br />management of stormwater runoff from the development is required because there is no public <br />stormwater system available to serve the property. At the same time, the applicant's geotechnical <br />analysis concludes that the site is not suitable for infiltration. Therefore, the applicant proposes to <br />direct stormwater runoff from the proposed development to the abutting City parkland to the <br />east. The site topography indicates that this is the natural drainage pattern. The applicant's on-site, <br />stormwater management system will include treatment facilities that also provide for some <br />detention. The overflow toward the east property line will be released at pre-development levels, <br />with rip-rap pads to disperse the flows at the. discharge points. The applicant also indicates that <br />level spreaders, consistent with the requirements of the City's Stormwater Management Manual, <br />could be utilized, if required. <br />Public Works staff notes that many of the proposed rip-rap outfalls are located within the public <br />wastewater easement along the east-property line. As conditioned previously at EC 9.8320(11)(b), <br />regarding prohibited uses in public easements, the stormwater infrastructure needs to be located <br />outside the public easement. With regard to the acceptability of overflow onto City parklands, Neil <br />Bjorklund, City of Eugene Parks and Open Space Planning Manager, confirms that this would be <br />acceptable, provided the runoff is discharged evenly and not concentrated at one or more points <br />along the shared property line. To meet this requirement, the following condition of approval is <br />necessary: <br />Staff Report: Oakleigh Meadows Cohousing September 2013 Page 25 <br />HO Agenda - Page 32 <br />
