additional peak hour trips, the development site's existing access connections are <br />exempt from this standard. <br />The proposed development site is subject to this standard. The shared access proposed for lots 4-10 <br />meets the standards at EC 7.420 Access Connections - Location. Access for Lots 1-3 will be further <br />evaluated during the building permit process. <br />(3) The standard at (2) may be adjusted if consistent with the criteria of EC 9.030(28). <br />Based on the foregoing findings, the development complies with these standards and no adjustment <br />is necessary. <br />(g) EC 9.6750 Special Setback Standards. <br />As discussed previously at EC 9.6805 and EC 9.6870, which is incorporated herein by reference, <br />adjacent streets comply with applicable right-of-way width requirements. No special setbacks are <br />required for future right-of-way or public utility easements. <br />(h) EC 9.6775 Underground Utilities. <br />All utilities will be required to be underground, consistent with this standard. <br />(i) EC 9.6780 Vision Clearance Area. <br />No encroachments within a regulatory Vision Clearance Area are shown. Should Vivian Drive be <br />improved in the future, Lot 7 would be subject to these standards, and analysis of potential Vision <br />Clearance Area encroachments would be evaluated at the time of building permit. <br />(j) EC 9.6791 through 9.6797 regarding stormwater flood control, pollution reduction, flow <br />control for headwaters area, oil control, source control, easements, and operation and <br />maintenance. <br />The applicant has provided a Stormwater Management Plan and Drainage Study prepared by Branch <br />Engineering detailing how runoff from the development will be managed. Stormwater runoff from <br />roofs, driveways, and other impervious surfaces of the development site will be collected in a shared <br />private storm drainage system that will be located within private easements or shared common areas. <br />The runoff from the private development will be detained and released to mimic existing flows and <br />drainage patterns. A stormwater quality facility is proposed to treat the shared driveway. <br />Staff notes that a maintenance agreement for the shared system will be required at the time of the <br />subsequent subdivision review. Additionally, if the private storm system is not addressed in CC&R's, <br />they will need to be covered by private easements. <br />EC 9.6791 Stormwater Flood Control - Existing drainage patterns will be maintained by discharging <br />stormwater runoff created by the PUD through a shared, private spreader system to the unimproved <br />Vivian Drive right-of-way. <br />Staff Report (PDT 15-1/ARA 15-13) October 2015 13 <br />HO Agenda - Page 20 <br />
