§ 17.70

The purpose of this chapter is to provide criteria for the design, plan preparation, and approval of required subdivision improvements and for final subdivision survey and monumentation.

(Ord. No. 2469, § 18, 11-2-2010)

All public improvements shall be designed and constructed in conformance with the Redding Municipal Code, city construction standards, applicable utility and transportation master plan(s), and the specific standards of any other utility company involved in the subdivision project. The city engineer shall have the authority to determine the appropriate final improvement design in the case of any uncertainly, variability, or conflict between potential improvement design options. Custom improvement design may be considered for approval in accordance with the subdivision modification criteria and process identified in Section 17.40.100.

(Ord. No. 2469, § 18, 11-2-2010)

Improvement plans and profiles for all subdivision-related work must be submitted to, and approved by, the city engineer before construction occurs. The plans shall be required before approval of the final map. All such plans and profiles shall be prepared in accordance with the requirements of the city engineer and shall conform to the approved tentative map.

(Ord. No. 2469, § 18, 11-2-2010)

A.

General. Improvement plans shall be prepared under the direction of and signed by a registered civil engineer licensed by the state of California. Improvement plans shall include, but not be limited to, grading, drainage, storm drains, landscape, environmental-protection measures, streets, sewer, water, electric, and related facilities.

B.

Form.

1.

Plans, profiles, and details shall be legibly drawn, printed, or reproduced on twenty-four-inch by thirty-sixinch mylar sheets. A border shall be made on each sheet, providing one-half-inch at top, bottom, and right side and one and one-half inches on the left side.

2.

A suitable title block shall be placed in the lower right corner or along the right edge and provide adequate space for approval by the city engineer and for approval of plan revisions.

3.

Plans and profiles shall be drawn to the scale of one inch equals fifty feet or larger unless approved by the city engineer. Details shall be drawn to such scale that clearly show the facility being constructed. The scales for various portions of the plans shall be shown on each sheet.

4.

A vicinity map shall be shown on the first sheet of all sets of plans.

5.

A north arrow shall be shown on each sheet when applicable.

6.

Plans shall be laid out to orient north to the top or right edge of the sheet, unless approved otherwise by the city engineer.

7.

If the plans include multiple sheets, a cover sheet showing the streets, lots, easements, storm drains, index, and vicinity map shall be included.

The form of all plans shall conform to additional requirements as may be established by the city engineer. The final form of all plans shall be approved by the city engineer.

C.

Contents. The improvement plans shall show complete plans, profiles, and details for all required improvements to be constructed, both public and private, including common areas. Street names must be shown. The plans will not be approved until the use of the street names is authorized in accordance with Chapter 17.64. Reference shall be made to city of Redding construction standards or state standard plans in lieu of duplicating the drawings.

D.

Grading Details. Information and details pertaining to grading and erosion control shall be provided in accordance with RMC Chapter 16.12.

E.

Soils Report. A preliminary soils report shall be provided in accordance with SMA Section 66490 and Section 66491, and RMC Section 16.12.060.C.

F.

Supplementary Plans and Calculations. Hydrology, hydraulic plans and calculations, bond estimates, soil or geological studies, structural calculations, and/or any other necessary special engineering study(s), shall be submitted with the improvement plans as required by the city engineer. All such reports and calculations shall be legible, systematic, and signed and dated by a registered civil engineer licensed by the state of California and in a form approved by the city engineer.

G.

Approval by the City Engineer.

1.

After completing all required revisions and obtaining any other necessary agency approvals, the subdivider's engineer shall transmit the originals of the improvement plans to the city engineer for signature.

2.

Upon finding that all required revisions have been made and that the plans conform to all applicable city ordinances, design-review requirements, and conditions of approval of the tentative map, the city engineer shall sign and date the plans. The originals will be returned to the subdivider's engineer.

3.

Approval of the improvement plans shall not be construed as approval of the gas, electric, cable television, and telephone service construction plans except as to location.

4.

Approval by the city engineer shall in no way relieve the subdivider or the subdivider's engineer from responsibility for the design of the improvements and for any deficiencies resulting from the design, from any required conditions of approval of the tentative map, or from obtaining permits or encroachment permits from other agencies or utilities.

(Ord. No. 2469, § 18, 11-2-2010)

A.

By Subdivider. Requests by the subdivider or the engineer for revisions to the approved plans appearing necessary or desirable during construction shall be submitted in writing to the city engineer or authorized representative and shall be accompanied by revised drawings showing the proposed revision. If the revision is acceptable, the originals shall be submitted to the city engineer's office for initialing. The originals shall be returned to the subdivider's engineer, and the revised plans shall be immediately

transmitted to the city engineer. Construction of any proposed revision will not be permitted to commence until revised plans have been received and forwarded to the city's engineering inspection division.

B.

By City Engineer. When revisions are deemed necessary by the city engineer to protect public health and safety or as field conditions may require, a request in writing shall be made to the subdivider and engineer. The subdivider's engineer shall revise the plans and transmit the originals to the city engineer for initialing within the time specified by the city engineer.

Upon receipt of the initialed originals, the subdivider's engineer shall immediately transmit revised drawings to the city engineer. Construction of all or any portion of the improvements may be stopped by the city engineer until revised drawings have been submitted.

If revisions are made that would be in conflict with the approved tentative map, the subdivider shall seek an amendment of the tentative map.

(Ord. No. 2469, § 18, 11-2-2010)

17.70.060 - Notification of commencement of work.

Construction shall not commence until the following has occurred:

1.

Improvement plans have been approved by the city engineer.

2.

A preconstruction conference is held with the subdivider and the city engineer.

The city engineer has been notified of the date construction will commence. If work is discontinued for any reason for a period exceeding thirty days, it shall not be resumed until the city engineer has been notified.

(Ord. No. 2469, § 18, 11-2-2010)

Final survey and monumentation for a subdivision shall be performed in accordance with the following:

A.

Permanent monuments shall be set at all angle and curve points on the exterior boundaries of the subdivision, in all street intersections, at all angle points of street lines, and at all curve points, both simple and compound, of street lines unless otherwise approved by the city engineer.
