3.1 General Requirements

The construction drawing submittal shall be a complete package which includes all details and documentation necessary for the construction of the proposed improvements. All plans shall be prepared by or under the direction of a professional engineer licensed to practice in the State of Colorado.

3.2 Cover Sheet

A cover sheet shall be provided with each submittal involving multiple roads or sheets. Cover sheets shall contain:

a. A vicinity map at a minimum scale of 1" = 2000' which shows the location and name of all arterial or collector roads within one mile of the development and all roads within the proposed development.

b. Legend.

c. Name or company name, address and phone number of the engineer preparing the plans.

d. General notes.

e. Description and location of permanent vertical bench mark based on U.S.G.S. datum. Where it is not practical due to lack of available existing benchmarks in the area of the development, the plans may reflect an assumed bench elevation upon approval of the Director of Public Works. In the case of an assumed bench elevation a minimum of two benchmarks will be established and identified on the plan. All such bench marks shall be located within the proposed development or within public right-of-way adjoining the development.

f. Name and phone number of all utility companies with mains, lines, or facilities potentially impacted by the construction.

3.3 Plan and Profile Sheets

Plan and profile sheets shall be submitted for all proposed roadway construction.

Plan view shall include, but not be limited to, the following:

a. The scale shall be a minimum of 1" = 50'.

b. Locations and dimensions of existing and proposed property lines, easements, and rights-of- way.

c. Lot numbers and lot lines and dimensions if the road is within a platted subdivision.

d. Road names.

e. Survey and project centerline stationing.

f. Centerline stations for all intersecting roads, public and private, and for commercial or industrial driveways.

g. Existing improvements shall be depicted by dashed lines and proposed improvements by solid lines. Existing and proposed road improvements include curb and gutter, sidewalk, pavement, culverts, guardrail, etc., and includes all structures and appurtenances whether public or private within the right-of-way.

h. Curve information including radius, interior angle, curve length, and tangent.

i. Elevation and stationing for all curb returns, points of curvature, points of tangency, angle points and high or low point of vertical curves.

j. Rate of superelevation if applicable.

k. Match lines and adjoining sheet numbers.

l. Existing and proposed utilities, both overhead and underground, including but not limited to water, sewer, electric, gas, telephone, storm sewer and cable television.

m. Stations and critical elevations of all utility and drainage appurtenances, existing and proposed.

n. Traffic control signing and striping.

o. Erosion control measures.

p. Landscaping.

Profile view shall include, but not be limited to:

a. Vertical scale of a minimum of 1" = 5'.

b. Existing grades shall be depicted with dashed lines, proposed grades shall be depicted with solid lines.

c. Continuous stationing for the entire portion of the roadway shown in the plan view, with the centerline stationing of all intersecting roadways, public and private, and commercial and industrial driveways clearly labeled.

d. All design elevations shall represent roadway centerline finish elevation. Additional profile views of curb and gutter, etc. shall be included as needed for clarity.

e. Vertical curve data including length of curve and stationing and elevation of p.v.t., p.v.i., p.v.c., high/low point.

3.4 Cross sections

Cross sections will not normally be required. The Director of Public Works may require cross sections when needed to clearly show the proposed method of widening or matching into existing improvements or method of handling steep side slopes.

3.5 Striping and Signing Plan

The signing plan shall show at a minimum:

a. Location of all existing and proposed signs, clearly indicating if existing signs are to remain.

b. Legend with reference to standard MUTCD designations.

c. Typical detail of installation dimensions.

d. Blank gauge and material of signs.

e. Note reflectorization provided.

The striping plan shall show at a minimum as applicable:

a. Striping material (paint, thermoplastic, etc.).

b. Color designation and line width.

c. Lane width.

d. Line type (solid, skip, etc.).

e. Typical details for any acceleration/deceleration lanes, turning lanes, cross walks, etc.

3.6 Details

Pueblo County Standard Details or Colorado Department of Transportation Standard Details may be referenced without being reproduced on the plans where no modification to a standard is proposed or required. Any modifications to standards will require a specific detail to be included.

3.7 Standard Notes

The following general notes shall appear on the cover sheet or first sheet of all construction plan sets:

a. The contractor shall provide all signs, barricades, flaggers and devices necessary to comply with the requirements of the latest edition of the Manual on Uniform Traffic Control Devices. No work within any County right-of-way may begin until a traffic control plan has been submitted to and approved by the Public Works Department.

b. The contractor shall notify the Pueblo County Public Works Department at least seven days before starting construction of any public improvements or any construction within the County right-of-way.

3.8 Record Set Drawings

No set of construction plans will be considered to have final approval, nor will construction be allowed to begin until two complete record set copies of the plans have been submitted to the Public Works Department. The record set will be clearly marked "Record Set", and shall bear the signature and seal of the professional engineer responsible for their preparation on every sheet of the plans.
