A. The
dimensions and specifications of sidewalks, curbs, gutters, drop curbs,
and entrance aprons in the City of Blue Lake are hereby adopted and
approved as specifically set forth in this chapter.
B. All
sidewalks, curbs, and gutters shall be constructed in accordance with

C. The
rules and regulations set forth in this chapter shall be enforced
by the Director of Public Works. As used in this chapter, "Street
Superintendent" means the Director of Public Works or his/her designee.
When any portion of a sidewalk is out of repair or pending reconstruction
or in a condition to endanger persons or property or in a condition
to interfere with the public convenience in the use of such sidewalk,
the owner or person in possession of the property fronting on that
portion of such sidewalk so out of repair shall be responsible for
inspecting and making repairs to such sidewalk and shall be directly
liable to any pedestrian or other person injured by reason of such
owner's or possessor's failure to so inspect and so repair the sidewalk,
whether or not the Director of Public Works has given the notice to
repair or replace provided for in
Streets and Highways Code Section
5611.
All decisions of the Director of Public Works, City Engineer, Building Department, or other City agency, department, officer or employee (except those of the City Council) which interpret, vary, or enforce the rules and regulations set forth in this chapter, shall be in writing and filed with the City Clerk. Such decisions shall be final 10 days following filing with the City Clerk unless an appeal to the City Council is filed within that time. Appeals shall be filed, heard, considered, and decided following the procedures set forth in Section
17.28.050. The City Council may by resolution set an appeal fee, but unless and until the City Council does so, no appeal fee shall be charged.
All sidewalks, curbs, and gutters shall be constructed of Portland
cement concrete and conform to the following specifications:
A. Materials.
Portland cement concrete shall be composed of Portland cement, fine
aggregate, coarse aggregate, and water, so proportioned and mixed
as to produce a plastic, workable mixture.
1. Unless
otherwise specified or required, the following is the strength requirement
and maximum size of aggregate for Portland cement concrete sidewalks:
Strength 28 Days
|
Maximum Size of Aggregate
|
---|
3,000 lbs.
|
1 1/2 inches per sq. in.
|
2. A
cubic foot of cement shall be considered as weighing 94 pounds and
shall conform to the requirements of the standard specifications for
Portland cement of the American Society for Testing Materials.
3. The
strength is defined as the average of compressive strength at 28 days,
as determined by breaking of any three consecutive standard six-inch
diameter by 12 inches height test specimens. All measurements, testing,
and processing shall be done in accordance with the current Caltrans
Standard Specifications.
4. The
water used in mixing the concrete shall be clean, free from oil, acid,
alkali or vegetable matter.
B. Subgrade.
The subgrade shall be free from all grass, roots, wood or other material
subject to decay, and shall be constructed true to grade and cross-section
at least four inches below the finished grade at all points throughout
the sidewalk width. It shall be thoroughly watered and rolled or hand
tamped until hard and solid before placing the concrete. All soft
or spongy soil within the sidewalk, curb, or gutter area shall be
removed to a depth of six inches below subgrade elevation, the resulting
space filled with sand or gravel and compacted until a firm and solid
foundation is secured. The sand or gravel shall be fully contained
beneath the concrete by a positive barrier. It shall not be allowed
to erode or fall away from beneath the concrete at the completion
of the work.
C. Forms.
1. Wood
forms for Portland cement sidewalks, curbs, and gutters shall be standard
form material with a true upper edge and a width equal to the full
depth of the finished sidewalk, curb, and gutter.
2. All
forms shall be properly braced by stakes.
3. Immediately
after removing the front curb forms, all holes, rock pockets, and
depressions shall be cleaned and filled with cement mortar, care being
exercised to obtain a bond with the concrete and to obtain the same
color as the surrounding concrete. All fins and other projections
shall be removed.
D. Curb
Radius.
1. The
curb returns at all right-angled intersection of streets shall have
a radius of 10 feet, and the curb return at all right-angled intersections
of streets and alleys shall have a radius of five feet.
2. All curb returns where the intersection angle is other than a right angle shall be shown on the plot plan required by Section
15.08.040(A) and approved by the City Engineer.
E. Construction.
1. All
Portland cement concrete sidewalks shall be not less than four inches
thick. After the concrete for sidewalks has been placed between the
side forms it shall first be tamped with a heavy tamper until a layer
of mortar has been brought to the surface. After the above tamping
has been completed, the surface shall be floated to a true and even
surface, troweled smooth, and finished with a fine hair push broom
drawn over the surface transverse to the line of traffic. Whenever
the grade exceeds 10%, the finished surface shall be floated to a
true and even surface and finished with a coarse push broom drawn
over the surface transverse to the line of traffic. If necessary,
water shall be applied to the surface immediately in advance of brooming.
All concrete surfaces shall be sprayed with a curing compound which
meets the requirements of Caltrans Standard Specifications.
2. The
surface of sidewalks shall be marked as shown on the standard construction
drawings, the marking to be done with a tool which will leave the
corners rounded. The finished surface shall be free from blemishes,
and when a 10-foot straight edge is placed thereon, the surface shall
not vary more than one-eighth inch from the edge except at grade changes.
3. Architectural surfaces shall be built only after approval by the Planning Commission pursuant to the site plan review process of Section
17.24.250.
F. Width.
The width of the sidewalk shall be as shown in the standard construction
drawings, unless otherwise designated by the Director of Public Works.
All curb entrances for driveways across any sidewalk shall be
constructed according to and as shown on the accepted standard construction
drawings, City of Blue Lake, for curb, gutter, and sidewalk and related
improvements.
A. All
concrete apron slabs shall have a minimum thickness of six inches.
B. All
commercial drop entrances shall be reinforced with three-eighths inch
deformed steel bars spaced on 12-inch centers and extending, on a
line parallel to the line of the curb, from the center of the curb
to three inches from the edge of the concrete on the inside of the
sidewalk; and on twelve-inch centers at right angles to the line of
the curb in the apron area and extending three feet on each side of
the apron. Wire mesh may be used as reinforcement in place of the
three-eighths inch deformed steel bar placed in the center of the
curb and an additional bar placed two inches above the bottom of the
curb.
When reinforced concrete entrance aprons are constructed, the
curb shall be reinforced with one three-eighths-inch deformed steel
bar placed in the center of the curb and two inches above the bottom
of the curb.
C. No
part of a drop curb driveway shall be constructed within eight feet
of the property line (if extended) at street intersections. Driveways
shall be confined within the limits of the frontage of the property.
Driveways shall not be constructed within three feet of street light
and traffic signal standards, poles, sign posts, fire hydrants or
other appurtenances. Driveway approaches located at the curb return
at alley intersections shall be constructed to conform to the alley
intersection pavement, where the pavement is in place, and if the
alley pavement is not in place, the approach shall be constructed
to conform to the standard sidewalk.
D. Every
person installing curbs, gutters, and/or sidewalks in the City of
Blue Lake shall comply with all applicable rules and regulations of
the law of the State of California, including those relating to the
Contractor's Licensing Board.
Barriers, lights, signs for public traffic control, standard
signs, and placement shall be in accordance with Caltrans Traffic
Manual requirements. The Director of Public Works shall have the authority
to direct the contractor to install such signs in accordance with
the Caltrans Manual.
