6. An urban facilities plan is the best method of providing a framework for capital <br />improvements programming in the River Road and Santa Clara areas, <br />7. Because of the substantial public investments already made in both neighborhoods, it is <br />most cost-efficient to achieve urban densities in River Road and Santa Clara prior to <br />accommodating new development needs in totally undeveloped areas. <br />8. The 1970 CH2M Hill Sewerage System Study, River Road-Santa Clara publication <br />demonstrates the feasibility of providing wastewater service to the River <br />Road- and Santa Clara area in a manner consistent with the Eugene-Springfield <br />Metropolitan Waste Treatment Alternatives Report (208 Facilities Plan) and the Metro <br />Plan. <br />9. The CH2M Hill publication defined study boundaries and made population projections <br />which are different than those contained in the Metro Plan; modifications to these factors <br />is occurring as part of the required system design work prior to construction. <br />10. The detailed design work which will occur as part of development of the system will <br />allow discussion of various system concepts with the residents and property owners of <br />the River Road and Santa Clara areas. <br />11. The River Road-Santa Clara Urban Facilities Plan has been completed. <br />12. Based on the River Road/Santa Clara Groundwater Study, Final Technical Report, <br />February, 1980 by Sweet, Edwards, and Associates, Inc., the Oregon Environmental <br />Quality Commission E C found on April 18, 1950, that: <br />a. The River Roadl_Santa Clara shallow aquifer is generally contaminated with fecal <br />coliform organisms in excess of drinking water and body contact standards. <br />b. Existing nitrate-nitrogen concentrations within the area exceed the planning target <br />on the average. <br />C. About 73 percent of the nitrate-nitrogen pollutants (and, by analogy, a similar <br />share of the fecal coliform contaminations) result from septic tank effluent. <br />Septic tank pollutants can migrate rapidly to the groundwater from drainfields via <br />macropore travel <br />13. The EQC concluded that a public health hazard exists based on fecal coliform data for <br />people using the aquifer. for domestic (drinking) or irrigation and that a health hazard <br />similarly exists in several areas based on nitrate-nitrogen levels. <br />14. To remedy the groundwater pollution problem, the Environmental Protection Agency <br />EPA awarded Eugene a grant to build a sewef-wastewater system to replace the <br />individual septic systems in use throughout River Road and Santa Clara according to a <br />II-F-3 <br />Laurel Ridge Record (Z 15-5) Page 147 <br />
