This Title defines the general requirements for improvements to be built by a subdivider or contractor working within the public way.

The required improvements shall include all street improvements in front of all lots along all dedicated streets to a connection with existing improvements of the same kind or to the boundary or the subdivision nearest existing improvements. Design must provide for future extension to adjacent development and be compatible with the contour of the ground for proper drainage. All water lines, sewer lines, and any other buried conduit shall be installed to the boundary lines of the subdivision.

Complete and detailed construction plans and drawings of improvements shall be submitted to the Zoning Administrator for the review by the City Engineer and Public Works Dept. prior to receiving Final Plat approval and prior to commencing construction. No construction shall be started until plans have been checked and approved by the City Engineer.

The following instructions are for the purpose of standardizing the preparation of drawings to obtain uniformity in appearance, clarity, size, and style. These plans and designs shall meet the standards defined in the specifications and drawings hereinafter outlined. The minimum information required on drawings for improvements is as follows:

All drawings and/or prints shall be clear and legible and conform to good engineering and drafting room practice. Size of drawings shall be 24″ x 36″ with one half (½) inch border on top, bottom and right sides, left side one and one-half (1½) inches.

A. In general, the following shall be included on drawings:

1. North arrow (plan), Vicinity Map, Drawing Index;
2. Scale and elevations referenced to an approved datum;
3. Stationing and elevations for profiles; and
4. Title block, to include:

a. Name of City
b. Project title (Subdivision, etc.)
c. Specific type and location of work.
d. Space for approval signature of City Engineer and date
e. Name of Engineer or firm preparing drawings with license number, P.E. stamp and signature.

B. Curb and gutter, drains and drainage structures, sidewalks and street surfacing drawings shall show:

1. Scale: one (1) inch equals twenty (20) or fifty (50) feet horizontal; one (1) inch equals two (2), five (5), or ten (10) feet vertical;
2. Both plan view and centerline profile must be shown. On subdivisions along steep cross slopes, profiles for each side of the street may be required to be shown;
3. Stationing and top of curb elevations with curve data with slope through curve must be shown at the beginning and end of all curves and at all intersection curb return points;
4. Flow direction and type of cross drainage structures at intersections with adequate flow line elevations;
5. Bench Mark (B.M.) location and elevation (use approved datum) shall be noted;
6. Typical cross-section for all street sizes and variations;
7. Street survey monument locations shall be required by the City Engineer; and
8. Plan and Profiles shall indicate design and/or existing grades a minimum of two hundred (200) feet beyond the limits of the proposed project.

C. Sanitary and Storm Sewer drawings shall show:

1. Scale: one (1) inch equals twenty (20) or fifty (50) feet horizontal; one (1) inch equals five (5), or ten (10) feet vertical. (may be shown on street drawings);
2. Location, size and slope of mains;
3. Location of sewer laterals into lots;
4. Manhole size, location and flow line elevation;
5. Type of pipe; and
6. B.M. location and elevation (use approved datum) shall be noted.

E. Each set of plans shall be accompanied by a separate sheet of details for special structures, which are to be constructed, and are not covered by the City Standards. All structures shall be designed in accordance with the minimum Tremonton City Standards.

F. Separate drawings of elements of the Tremonton City Standards shall not be required to be redrawn and submitted with the construction drawings unless specific deviations from the Standards are requested for approval; however, the construction drawings shall refer to the specific items of the Standards that are to be incorporated into the work.

G. Once the City Engineer approves the construction drawings, a minimum of three (3) sets shall be submitted with one set retained by the City Public Works Department, one by the City Engineer, and one set returned to the Subdivider, Developer, Contractor or Project Manager. This approved set shall be kept available at the construction site. All sets of approved construction drawings shall be marked as approved by the City. Prior to final acceptance by the City, the subdivider, developer, contractor or project engineer shall submit to the City Public Works Department a set of reproducible mylar or vellum “as constructed” drawings for permanent city file record.

A preconstruction conference shall be held before any excavation or other work is begun in the subdivision or Project.
