Document Description
The Sewer Relief Trunk – from Renz Lane to Highland Avenue Project (“Project”) proposes the installation of approximately 6.6 miles of sewer trunk line that would extend from the termination of the previously constructed Harding Avenue segment of the relief trunk sewer located at the intersection of Harding Avenue and Highland Avenue in San Martin, southeast to the previously constructed City of Gilroy segment of the relief trunk sewer located on Renz Lane in Gilroy. The proposed project alignment is located in the unincorporated Santa Clara County in the San Martin planning area and in the City of Gilroy. Land uses within this area are designated Neighborhood Commercial, Industrial, Recreation, and Urban Low and Urban Medium Density Residential. The proposed trunk sewer alignment would be located mostly within the existing roadway right-of-way, plus a few new utility easements. Generally, the trunk line would be located in the paved roadway, unimproved private roadway, two highway crossings, one UPRR crossing, and two waterway crossings, as discussed in more detail below. The existing sewer trunk line that travels from Morgan Hill through San Martin to Gilroy is owned jointly by the City of Morgan Hill and the City of Gilroy. The new relief trunk line will be owned entirely by the City of Morgan Hill.
