Reservoir, west of the City's urban growth boundary. The western portion of the subject property (west of the proposed intersection of West Amazon Drive and Canyon Drive) currently sheet-drains to the westerly and middle onsite waterways. The nearest piped stormwater system is within Martin Street. Applicant's Proposal The applicant responds to above approval criterion in its written statement as follows: This proposal will comply with the city's stormwater ordinance. See the plan sheet for stormwater. See Stormwater Study by Weber Engineering, Exhibit P hereto. In summary, all standards in the stormwater ordinance will be met by this development, proposal. The applicant's plans (Sheets L11 and L12) show the western portion of the site being served by a proposed extension of the piped stormwater system from Martin Street and the eastern portion of the site draining to the easterly waterway. Exhibit P of the application materials include a letter dated February 17, 2012 from Doug Weber, Principal Engineer, Weber Engineers & Associates, PC and a "Hydrology Study for Deerbrook PUD," dated February 27, 2007, also prepared by Weber Elliot Engineers, PC. The February 17, 2012 letter states: I am writing this letter in support of the planned application for the Deerbrook PUD under the Needed Housing standards in the zoning code. On June 30, 2008, Weber Elliott Engineers, PC submitted a report titled "Hydrology Study for Deerbrook PUD" as part of an earlier application for the PUD. This letter is to support compliance for the stormwater criteria of the land use code. The current existing site conditions have not been altered and the site hydrology remains the same as when the report was created in 2008. The proposed site plan is substantially the same as previously submitted therefore the report is still valid for this submittal. The applicant submitted a report.with a different date than cited by the design professional. In this instance, Mr. Weber refers to a study dated June 30, 2008, which was not submitted by the applicant. Instead, the applicant submitted a study dated February 27, 2007. Although the applicant submitted an older report, it is for the same property with a virtually identical development plan. The 2007 hydrology study showed the western portion of the development being served by a piped stormwater system to be extended from the existing system in Martin Street. The 2007 proposal also showed an outfall to the middle waterway, from offsite drainage to the south. The current proposal is nearly identical to the 2007 proposal, except the outfall to the middle waterway appears to be eliminated. The applicant's Exhibit KK is a letter from Mr. Weber explained that the 2007 hydrology study is the most current study. Western Drainage Basin The western portion of the site shows a piped stormwater system extended from Martin Street within the proposed streets, with an interconnecting piped system between the streets at the Hearing Official Decision (PDT 10-2, CU 11-1) 29
