RE: New Subdivision Plat at Southwest comer of 2"d East St. (Salem Rd.) and Cemetery Rd.
Dear Gary,
As per our telephone conversation, I researched our Transportation Plan to find out what the Right-of-
way widths for 2"d East St. and Cemetery Rd. are supposed to be Attached are the approved typical
sections for these two streets.
2"a East St. is designated a Major Arterial with a Bike Path (Typical Section # 8) and has a 125 ft.
wide right of way. Therefore the new plat should show a 62.5 ft. wide '/2 street right of way width for
this street. The actual construction of the street sidewalk, landscaped strip, curb and gutter, paving,
etc. will be done in various phases. The existing new curb and gutter could probably be used for the
first phase. The back of sidewalk would probably be located at the street right of way line and the
area in between the sidewalk and curb and gutter would be a wide landscaped strip for a while. It is
my understanding from John Millar that the irrigation ditch along the west side of 2"d East St. is
supposed to be put into a 48" culvert. The flowline of this ditch is so high that the top of a 48" pipe will
be up near the surface of the future widened roadway. The strength of the pipe becomes a critical
element at shallow cover depths, therefore the pipe will probably have to be a Class 5 reinforced
concrete pipe to have enough strength to handle the concentrated loads near the surface of the future
roadway.
Cemetery Rd. is designated as a Major Residential Collector or Business Street (See Typical
Section # 4). The new plat should show a 39.5 ft. wide r/z street right of way width for this street..
The asphalt surface of the existing road is quite a bit higher than the surrounding ground elevation. Are
you going to put the new curb and gutter and sidewalk high enough to match the existing asphalt surface
or will you be taking out the existing road and rebuilding the street at a lower elevation that more nearly
matches the existing ground? If you are going to try to use the existing road, your engineer/survey
crew will need to get elevations along the surface of the existing road so the new curb and gutter can be
designed to match it. They will also need to get some test hole information to determine what the
depths of the layers of the existing Granular Borrow, 3/4" Aggregate Base and Asphalt Plantmix
Surface are. The City's long range plans for water and sanitary sewer call for a 12" waterline and
also a 12" sanitary sewer line going to the west along Cemetery Road. Attached are Shts 5 & 6 of the
plans for the recent street widening work along 2"d East St. at Cemetery Road. These plans show
the locations of the "12"stubouts" for the existing water and sanitary sewer lines.
We need to get the Annexation Agreement for the subject development started right away. It will
cover such things as the different "Phases of Construction" that you propose for the widening of 2"d
East St. and the construction/widening of Cemetery Rd. It would also cover City participation in the
extra size (8" vs 12") requirements for the waterline and sanitary sewer lines along Cemetery Rd. It
would also cover the property owner reimbursement to the City (at $10 per R. per each utility line) for
the city -installed water and sanitary sewer lines along 2nd East St.
As soon as you get some preliminary Street & Utility Improvement Drawings for the subject
development, we would like to sit down with you and discuss your ideas regarding the phasing of the
street, water, sanitary sewer, stone drain and irrigation facilities. We would like to meet with you at
your earliest convenience so our reviews and the lack of an Annexation Agreement don't hold up the
planned construction of the development.
Very truly yours,
JOSEPH A. LAIRD, RE
CITY ENGINEER
