base zoning and designation allowing residential uses can still be developed with such uses on those portions of the lot that are not within the /WR conservation area. 2. If the setback and resource site occupy more than 33% ofa development site area, upon application of the property owner, the City will reduce the size of the IWR conservation area to ensure that the area constitutes no more than 33% of the development site area. EC 9.8030(21)(a). 3. Upon application of the property owner, the City will reduce the setback area around a Goal 5 wetland by up to 20%, consistent with specified standards. EC 9.8030(21)(b). 4. Upon application of the owner of sites identified with certain streams and wetlands, setback averaging can be used to reduce setback distances to up to 30% on portions of the site. EC 9.8030(21(c). 5. Upon application of the property owner, adjustments can be made to the /WR overlay zone standards to ensure that an owner is not deprived of uses that are permitted to other owners affected by the same, or a similar, resource site in the same zone. EC 9.8030(21)(d). Considering these provisions of the /WR overlay zone, the application of the overlay zone to a property zoned and designated for residential use does not result in a diminution in the area's supply of residential land. Even supposing the provisions above were not a part of the overlay's regulations, the overlay is being applied to such a small number of acres included in the area's inventory of residential lands that this ordinance overlay could not diminish the area's supply ofthose lands below the projected need. An analysis of potential impacts to the supply of buildable residential lands within the Eugene UGB was conducted using the regional Geographic Information System (GIS), data provided by City of Springfield staff and calculations of supply and demand from the Supply and Demand Technical Analysis ofthe Eugene- Springfield Metropolitan Area Residential Lands and Housing Study (RLHS), 1999. The State-acknowledged Eugene-Springfield Metropolitan Area Residential Lands and Housing Study included a surplus of residential acreage of 1,862 acres (considering a low demand assumption) or of790 acres (considering a high demand assumption). This acreage represents those lands that were designated as residential lands, beyond the acreage needed to accommodate the projected 20-year demand. Since the adoption of that Study, Eugene and Springfield have taken various actions that have decreased the amount of surplus residential acreage, resulting in a current surplus of either 1,725.07 acres (considering a low demand assumption) or of653.07 acres (considering a high demand assumption). Even ifthe provisions described in 1 through 5 above were not included in the ordinance, the Goal 5 protection measures contained in this ordinance could affect, at most, 445.77 acres of residentially 7
