4.325 Construction and Repair of On-Site Sewerage System.
(1) Except as provided in subsections (2) and (3) below, no person shall repair, replace or increase the capacity of an existing on-site sewerage system, nor construct a new on-site sewerage system in order to avoid connection to a public sewer collection system.
(2) An existing on-site sewerage system may be repaired or replaced provided the building(s) served is more than 300 feet from a public sewer, measured by the shortest distance, or connection to a public sewer is physically impractical due to topographic or man-made features.
(3) An on-site sewage system may be expanded, or a new system installed, provided the following conditions are met:
(a) The subject parcel is more than 300 feet from the nearest existing public sewer.
(b) No more than one single-family residence exists or is proposed for the parcel.
(c) The new or expanded system receives approval from the Oregon Department of Environmental Quality and/or any other agencies with authority to regulate on-site sewerage systems.
(d) A financial guarantee is provided to the City in the amount established in the most recent fee schedule approved by resolution of the City Council. This guarantee must be accepted by the City prior to the issuance of any permits for the property. Said financial guarantee shall be held until one of the following conditions has been met:
(i) The public sewer improvements have been constructed by the property owner, at which time the guarantee may be released in whole or in part; or
(ii) The required sewer improvements have been constructed as part of a Local Improvement District, in which case the deposit shall be applied to the proportional share of the property owner’s obligation and the remainder, if any, returned.
(iii) The sewer improvements are constructed by the owner of the public sewer, in which case the guarantee shall be applied as a proportional share toward the necessary extension. If the subject property’s proportional share of the improvement project is less than the amount of the guarantee, the difference shall be released.
(4) New development which does not meet the criteria of (2) and (3) above, including partitions or subdivisions on which there exists an existing septic system, are required to connect to the public sewer as described in Medford Municipal Code Chapter 10.
