According to the Public Works Department, long runs of private water lines within the road right-of-
<br /> way create conflicts with maintenance and construction activities that occur along roadways. In
<br /> addition, the Utility Services Department has verified that a property owner can have a difficult time
<br /> maintaining a long service line and can experience a significantly high water bill if a leak or break goes
<br /> undetected or is difficult to pinpoint and repair. Thus, long runs of private service lines can cause
<br /> problems for the county and for residents.
<br /> In its evaluation, staff considered various maximum distances that a property can be from a main line
<br /> and connect to a county owned system that is limited to a distance of 500 feet from a main line. Those
<br /> maximum distances were 500 feet, 1,000 feet, and 2,500 feet. In evaluating distance standards, staff
<br /> identified the general size and layout of parcels located outside the USA in order to develop a typical
<br /> connection scenario.
<br /> In the area of the county east of 1-95,most properties outside the USA are 5 acres or larger in size and
<br /> have dimensions of roughly 330' x 660'. Usually,those five acre parcels are oriented with a 330' width
<br /> along a road right-of-way. Consequently, a typical parcel arrangement outside the USA results in one
<br /> parcel every 330 feet. Under that arrangement, a property that does not front on the main line is
<br /> separated from the main line by one or more 330 foot wide intervening parcels. Thus, a property
<br /> separated from the main line by one intervening parcel would typically be within 500 feet of the main
<br /> line, while a property located 1,000 feet from the main line would be separated from the main line by
<br /> two or possibly three parcels. A property located 2,500 feet from a main line would be separated from
<br /> the main line by as many as seven intervening parcels.
<br /> Based on the scenario described above,where the county-owned system is extended a maximum of 500
<br /> feet from a main line,four standard 5 acre(330 foot wide)parcels,including two parcels not adjacent to
<br /> the main line, could connect to the county centralized system. A 1,000 foot standard would allow
<br /> connection of 3 to 4 additional parcels not covered under a 500' standard,resulting in a total of 6 to 8
<br /> connections. Finally, a 2,500 foot standard would allow connection of an additional 8 parcels not
<br /> covered under a 1,000' standard, resulting in a total of 16 connections.
<br /> Attachments 6A,613,and 6C illustrate how parcel layout,limited right-of-way width,and distance from
<br /> a main line affect connections. That attachment depicts the 66'''Avenue main water line,distance marks
<br /> going west along 12'b Street from that line(500' at the green mark; 1,000' at the yellow mark;2,500' at
<br /> the red mark), and the actual lay-out of parcels along 12'b Street west of 66h Avenue. In addition, the
<br /> attachment shows individual parcels on both sides of 12th Street and labels those parcels A-D and 1-11.
<br /> Unlike most areas of the county outside the USA,the parcel layout shown in attachments 6A, 613, and
<br /> 6C includes a number of parcels that are significantly narrower than the conventional 330' width;
<br /> therefore, attachments 6A, 6B, and 6C do not illustrate a worst case scenario with respect to distances
<br /> along or across intervening parcels.
<br /> As illustrated by the attachment,a county-owned line extending 500' west of the 66th Avenue main line
<br /> would serve four parcels that directly abut that line (parcels A, B, C, and D). The attachment also
<br /> shows that, at a point 1,000' west of the 66`x' Avenue main line (at the yellow mark), three additional
<br /> parcels along 12th Street(parcels 1, 2, and 3)could be served if properties within 1,000' of a main line
<br /> were allowed to connect. In addition, the attachment shows that, along 12a' Street within 2,500' of the
<br /> 66th Avenue main line (at the red mark), there are eight more properties (parcels 4-11) that could be
