I 9. 6. An urban facilities plan is the best method of providing a framework for capital improvements programming in the River Road and Santa Clara areas, 7, Because of the substantial public investments already made in both neighborhoods, it is most cost-efficient to achieve urban densities in River Road and Santa Clara prior to accommodating new development needs in totaHy undeveloped areas. 8. The 1970 CH2M Hill Sewerage System StUiZV River Road-S'ama (-;lara publication demonstrates the feasibility of proy iding SfHlltary ~~e"Yer~;WQ~~;~~:~t~X-..::i-gX.'xj.x~ to the River Road-.,,~.nQ...Santa Clara area in a manner consistent with the Eugene-Springfield lHetropolitan rVaste Treatment Alternmives Report (208 Facilities Plan) and the l'vfetro Plan. The CH2l'll I:EILpubHcation defined study boundaries and made population projections which are different than those contained in the Metro Plan; modifications to these factors is occurring as pan of the required system design work prior to construction, 10. The detailed design work which will occur as part of development of the system will allow discussion of various system concepts with the residents and propertY' owners of the River Road and Santa Clara areas. 11. The River Road-Santa Clara Urhan Facilities Plan has been completed. 12, Based on the River Road<S'anta Clara Groundwater Study. Final Technical Report, February, 1980 by Sw'eet, Edwards, and Associates, Inc., the Oregon Environmental Quality Commission(r~Q() found on April 18, 1980, that: ii. The River Road/~Siinta Clara shallO\v aquifer is generally contaminated with fecal coliform organisms in excess of drinking\vater and body contact standards, b, Existing nitrate-nitrogen concentrations \yithin the area exceed the planning target on the average. c. About 73 percent of the nitrate-nitrogen pollutants (and, by analogy, a similar share ofthe fecal colif<.mn contaminations) result from septic tank effluent. Septic tank pollutants can migrate rapidly to the ground\.vater from drain fields via macropore traveL 13, The EQC concluded that a public health hazard exists based on fecal coliform data for people using the aquifer for domestic (drinking) or ilTigation and that a health hazard similarly exists in several areas based on nitrate-nitrogen levels. 14. To remedy the groundwater pollution problem, the Environmental Protection Agency CeJ~i),tavvarded Eugene a grant to build a ~:t)we.:.'lY~l~l~W;:W;Lsystem to replace the i~dividual septic systems in use thwughoutRiver Road and Santa Clara according to a II.F-3
