Environmental Services
Water
The existing water line is a two -inch diameter pipe and will need to be upgraded.
The proposed water line can connect where indicated on the plans, however an
upgrade of the water line from U.S. 1 will be necessary. The contractor will need
to submit the designed plans for the water connecting to the existing eight -inch line
on U.S. 1 to the Department of Health for permitting. Once the permit is received,
the City will extend a six -inch water line from U.S. 1 to the designated connection
point on the plans.
Contractor will design and permit; City will run to property line of subdivision.
Sewer
• No comments on the sewer line proposal are necessary.
OK
Roadway
• As this will be dedicated to the city as a public roadway, density tests compacted to
98% based on Aashto T -180 will be necessary for the sub base.
OK
Stormwater
• Hans Wolfer will be evaluating the design of the stormwater system for this
project, however, based on the stormwater drawings, it is not apparent as to who
will be responsible for maintenance of this system once completed. The letter
stated that the roadway and right -of -way will be turned over to the City and there
will be no common areas. This could only mean that the individual homeowner's
are responsible for the maintenance of the retention pond and swale areas. This is
impracticable as if one homeowner does not maintain his area, it could have
adverse affects on the other homeowners.
So noted, however applicant wishes to convey maintenance to homeowners.
Fire Department
• NFPA 1 (Fire Prevention Code) requires a "turnaround shall have a minimum
centerline radius of 50 feet ". The cul -de -sac shown on the plans does not appear to
meet this requirement.
50' is measured from center of cul -de -sac to center of road. Mr. Bennett was given a copy
of the pertinent section of the NFPA 1 Code.
Legal Department
