(b) Individual Private Wells: Individual private wells must meet the construction requirements of the Oregon State Water Resources Department and be located in accordance with requirements of the State Health Division in relation to public or private sewage disposal systems. The bacteriological quality of this water may be determined through the Marion County Health Department. Upon receiving the recommendations from the State Health Division or Marion County Health Department, the Hearings Officer or Commission may require the use of an engineered public or private water system in any proposed subdivision. Other criteria to be considered in making this determination are the recommendations contained in the Marion County Water Quality Management Plan, Marion County Comprehensive Plan, and Chapter 181 of the Marion County Rural Zoning Ordinance. The applicant indicates that water will be provided by individual private wells, not by a private or public water system. Privately owned wells — including their location — are not regulated by Marion County. Wells in the development must meet the requirements of the Oregon Water Resources Department. 17.172.430 STORMWATER MANAGEMENT. The impact of proposed of subdivisions and partitions on stormwater runoff shall be evaluated and potential adverse impacts shall be mitigated.

Compliance with this requirement shall be demonstrated by compliance with department of public works engineering standards.
