SECTION 6 Integrated Stormwater Management Strategy Development Standards: Potential development standards were considered for addressing water quality problems associated with future development as part of the 2002 City -wide basin master planning efforts. As a result, development standards for water quality were adopted City -wide in June 2006. These standards apply within the city limits and to properties within the urban growth boundary (UGB) that develop and annex to the City. These standards require developers to implement water quality best management practices to treat runoff from their sites. In addition, following up from 2008 City Council direction related to increasing the use of LID practices, specific administrative adjustments, incentives and other LID- related actions are being identified and prioritized for implementation. On- Street Rain Garden Concept Options for Local Streets: Street -side rain garden concept options for local street improvements were developed to address UIC decommissioning needs as described in Section 4.3.1. However, these options are envisioned to be employed for various circumstances beyond UIC - related projects. Implementing the street -side rain garden concepts will require modifications to the City's Local Street Plan under a separate process subsequent to completion of the River Road Santa Clara Basin Plan. Water Quality Protected Waterways Ordinance: New regulations went into effect on June 10, 2009 that provides protection of approximately 13.5 miles of waterways through the use of a Water Quality Overlay Zone. The new regulations fill gaps in protections on a set of waterways of significance to water quality, and acknowledge the significant incidental water quality protection already provided by the Goal 5 Water Resources Overlay Zone. Natural Resources Management Strategy The proposed strategy, similar to the strategy for the six other stormwater basins in Eugene, is focused on the protection and enhancement of open waterways for their stormwater functions and benefits. The strategy includes both a capital project and development standards component. Capital Projects: Three capital projects have been identified for implementation in River Road Santa Clara as follows: RRSC — 4 - Stream Corridor Acquisitions: Acquire the Willamette Overflow, also referred to as the East Santa Clara Waterway Corridor. Capital projects RRSC — 1 — Streambank Stabilization and RRSC — 3 — Outfall Stabilization will also provide natural resource benefits. These projects were listed as part of the water quality strategy and are not listed separately here to minimize duplication. Development Standards: Part of the strategy includes support for existing waterway protection standards (i.e., Water Resources Conservation Overlay Zone, Natural Resource Zone, Planned Unit Development provisions, Site Review provisions as applicable). Another part of the strategy involves coordinating with other related on -going efforts (NR Study, ESA) to ensure that, ultimately, the stormwater functions and benefits of stream corridors are protected. Lastly, waterway protection will occur under the implementation of the June, 2009 ordinance that will include a Water Quality Overlay Zone (this is included above under the water quality strategy). 0:\25695978 Eugene RR -SC Final Basin P1an\Master P1anTINAL 2- 2010\Master_Plan 3- 11- 10_FINAL_ Word _Version.doc 6 -4
