Chapter 15.65
CONCRETE CURB, GUTTER, SIDEWALKS, AND TRAILS
Sections:
15.65.040 Testing and inspection.
15.65.050 Cold weather concrete.
15.65.010 General.
All concrete work shall comply with the APWA Standard Specifications, unless noted otherwise in this chapter. The work shall consist of curb and gutter, sidewalk, combination curb, gutter and sidewalk, cross gutters, and curb return constructed where indicated on the plans or as directed by the engineer and conforming in all respects to the specified lines, grades, and dimensions. A minimum slope along any curb and gutter shall be 0.7 percent and on cross gutter shall be one-half percent. Maximum grades on curb and gutter and streets shall be 10 percent. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 13.010)].
15.65.020 ADA requirements.
All pedestrian facilities will conform to the current federal ADA standards. Plastic inserts required per ADA mandate shall be yellow in color. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 13.020)].
15.65.030 Base material.
There shall be a minimum of six inches compacted crushed gravel road base under all concrete for public use on both sides. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 13.030)].
15.65.040 Testing and inspection.
A. Scope. All materials and processes involved in the construction shall be subject to testing and inspection as detailed in the various subsections of this section and in general compliance with ASTM E105-54T. Results of tests performed by recognized laboratories to the satisfaction of the engineer shall be accepted by the supplier as a basis for acceptance or rejection of any and all materials. Standard methods of sampling and testing shall be used. The latest appropriate ASTM tests and methods shall be considered to be standard, and will include but not be limited to concrete, cement, aggregates, additives, curing compounds, parting compounds and jointing materials.
B. Concrete. Where required by the engineer, samples of concrete will be tested to ensure quality concrete. The city engineer or his/her designee will take at least one of these tests for every 50 cubic yards of concrete poured or as required.
1. Samples of wet concrete may be tested for air content. Failure to indicate the entrained air specified in this section shall be a basis for rejection of all concrete represented by the test.
2. Samples of wet concrete may be tested for slump. Failure to indicate the required slump shall be a basis for rejection of all concrete represented by the test. Slump to be five inches maximum, air to be six percent plus or minus one percent.
3. Concrete compression specimens shall be taken for each pour of section as required by the engineer. Such specimens shall attain the specified strength of 28 days with the provision that no specimen may indicate a compressive strength of less than 90 percent of the strengths nominated and with further provision that results from specimens which, in the opinion of the testing authority and the engineer, are obviously faulty or defective may be rejected in determining the requirements. Should any specimens fail to satisfy these requirements, the concrete represented thereby shall be removed and replaced, except that the contractor may submit evidence based on ASTM designation C42-49 which shall be considered by the engineer in relation to this requirement.
C. Flow Tests. All curbs and gutters and cross gutters will have a flow test prior to final inspection to determine any low or high spots. (The city will be present.)
D. All forms or string lines must be inspected by Eagle Mountain City before concrete may be poured. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 13.040)].
15.65.050 Cold weather concrete.
Concrete shall not be placed when a descending air temperature in the shade and away from artificial heat falls below 35 degrees Fahrenheit. Concrete shall not be poured on frozen ground. Where high temperatures are likely to descend below 32 degrees Fahrenheit, concrete shall be covered or otherwise protected against freezing. The city engineer must approve the method by which the concrete is covered or protected. Admixtures other than calcium chloride may be added upon approval of the city engineer. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 13.050)].
15.65.060 Clean gutter.
Once curb and gutter and surface course is in place it shall be kept as clean as possible. When equipment is required to cross over sidewalk, bridging will be provided to protect concrete. Dirt and gravel will not be placed in gutter or on street. Gutter will flow freely at all times. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 13.060)].
15.65.070 Drive approaches.
All concrete for a drive approach shall be six inches thick in the public right-of-way with six inches of gravel base compacted to 95 percent density. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 13.070)].
15.65.080 Asphalt trails.
Asphalt trails shall be 10 feet wide along pedestrian corridors or unless otherwise approved by the city council. Asphalt trails shall consist of six inches of base and three inches of asphalt and shall be placed on undisturbed native material or documented fill material properly compacted. Base shall extend past trail edges six inches both sides. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A)].
