Marian Meadows Rezone and Subdivision Final Environmental Impact Statement 1-10 The applicant has indicated that there is the potential for a subsequent application for a quarry on portions of the site. Preliminary identification of a potential quarry site indicates that the quarry proposal may affect the viability of the roadway corridor indicated for access to the steeply sloping eastern portion of the site. The quarry location intercepts the projected alignment of that roadway. Depending on the location, amount and configuration of excavation for the quarry, provisions made for continuation of the road through the quarry site, and the underlying characteristics of the rock formations, the long-term stability of this roadway corridor may be affected. These issues, together with assessment of impacts on other elements of the environment, would be addressed in an environmental review for a subsequent application for the quarry site. 5 What alternatives are considered? Four alternatives to the applicant’s proposal have been developed, with some options related to site conditions and the nearby airport:  Alternative 2: Planned Unit Development (PUD), retains the maximum number of units allowable under a PUD, but locates all 443 units on the western flatter portion of the site. It employs a mix of single-family and multi-family units and includes the mini-storage use. No Action Alternatives presume development without approval of a PUD:  Alternative 3A: No Action with Uniform 3-Acre Lots illustrates development of the entire site at the existing zoning, which requires 3-acre minimum lot sizes. The conceptual layout includes a uniform distribution of lots over the proposed development. It calls for a development consisting of about 147 lots with 143 units provided by the 430 acres zoned Rural (R-3), and 4 units provided by the density allowance in the 90 acres zoned Forest and Range (FR). This option would include water district service but would employ individual on-site sewage disposal rather than a sewage treatment plant. The entire site would be subdivided; the mini-storage use included in Alternatives 1 and 2 would not take place.  Alternative 3B: No Action with 3-Acre Lots with Exclusions has the same features as Alternative 3A, except for exclusion of the area northeast of the BPA easement for development of up to 300 mini-storage units. It would have about147 lots.  Alternative 3C: No Action with 3-Acre Lots Excluding the Eastern Portion of the Site has the same features as Alternative 3A, except for exclusion of the steep eastern portion of the site and results in a substantial reduction in units to between 30 and 35 lots. The mini-storage use is not included.  Alternative 3D: No Action with 5-Acre Lots in Airport Safety Zones (ASZ) subdivides the portion of the site within ASZs at a density of one unit per 5 acres. This results in 68 lots in the ASZs, 45 lots outside the ASZs, and about 113 lots overall. The mini-storage use is not included.
