13-06-006-0001 Layout

Street plans are to conform to the layout of the approved site plan, preliminary plat, a previously recorded plat or to recorded right-of-way documents and easements, and the street design criteria in this document. (Ord. 2017-22, Rep&ReEn, 07/05/2017)

13-06-006-0002 Plan Presentation

Plans, profiles, and typical cross-sections are required, which contain the following minimum information:

A. Plans.

1. Street names.

2. Lateral dimensions of streets and rights-of-way, including all pertinent survey data and curb return data.

3. Location of existing and proposed utilities and existing streets to be joined.

4. Drainage structures, including cross gutters, culverts, catch basins, or similar items. Distinguish between existing drainage structures and those proposed. Show a positive outlet for all drainage and any effects on the downstream property.

5. Curb, gutter, sidewalks, and asphalt structures.

6. Benchmarks in accordance with Section 13-03-003-0003.

7. New traffic control devices, all existing traffic control devices within the area of the project, and changes in traffic control devices in the vicinity of the project, which are required as a result of the project.

8. Existing and new streetlights conforming to the approval site plan or preliminary plat.

9. The top and toe of slope for both cuts and fills.

10. All curve data shown on the plans shall show a delta, radius, length of arc, and tangent.

11. Survey monument installation shall be in accordance with Section 13-03-002-0007.

12. Additional information needed to clarify plans or deal with specific conditions.

13. All plans shall meet requirements of Division 13-06-003 if separate grading plans are not included.

14. Blue Stake sticker on all sheets.

15. Resource protection areas.

16. Flagstaff Urban Trails System.

17. Erosion protection measures for roadway slopes (cut and fill).

18. All areas disturbed by grading shall be seeded in accordance with Chapter 13-17.

B. Profiles.

1. Benchmarks in accordance with Section 13-03-003-0003 shall be shown.

2. Existing and Finished Grade Profiles. Triple profiles of centerline and both sides of top of curb or edge of pavement if no curb is proposed are required. The presentation must clearly show and distinguish existing profiles and other profile information.

3. Finished elevations, including PVC, PI, and PVT of vertical curves, intersection points, and all other points needed for good vertical control of construction.

4. Slopes and vertical curve lengths.

5. Curb return profiles at intersections.

6. Drainage structures and utilities crossed.

7. Extension of profile a minimum of two hundred (200) feet past the end of the improvement project or as required by the City Engineer to ensure that design is compatible with future extension.

8. Consistent stationing throughout the plans.

9. Additional information needed to clarify profiles or deal with special conditions, e.g., profile of drainage channels, stationing and elevations at beginning and end of all curb returns, grade breaks, and beginning and end of construction.

C. Cross-Sections.

1. Typical Cross-Sections. A typical cross-section is needed for each condition encountered and should be clearly identified as to where it is applicable.

2. Materials and thickness, including select material, aggregate base, prime coat, asphaltic concrete, chip seal coat, curb and gutter, and sidewalk, with notation of the engineering firm preparing the soils report and that report number. The specification and type of material shall be stated. Under-drains may be required if deemed necessary.

3. Horizontal dimensions to all key points.

4. Cross slopes (maximum and minimum if cross slope varies).

5. Parkway Conditions. Maximum and minimum slopes are to be shown for cuts, fills, and side hill conditions. Any side ditches or other special conditions are to be shown.

6. Shall show right-of-way widths, relation to centerline, and shall identify by name, the street to which it is applicable.

7. Identify limits of applicability by station if necessary.

8. Shall show typical location of traffic signals, signs, street lights, fire hydrants, and other pertinent manmade features.

9. When an existing road is being widened, sufficient information shall be provided to demonstrate that the new improvements will match the existing road while meeting City standards of cross-slope and longitudinal slope. Minimum information shall include elevations of the existing road at centerline and edge of pavement at twenty-five (25) foot intervals. This information shall be shown in plan view and on cross-sections together with the proposed improvements. In certain instances, this may require moving portions of an existing road to meet these objectives. (Ord. 2017-22, Rep&ReEn, 07/05/2017)
