Solano County Municipal Code § 26-114 Improvement plans

The subdivider’s engineer shall prepare plans and specifications for improvements required for the proposed subdivision by this Chapter or the Subdivision Map Act.

(Ord. No. 1608, §2)

Improvement plans shall be submitted to the County Engineer before or at the same time as the improvement agreement to which they relate or, if the work is to be commenced before execution of an improvement agreement, before the commencement of the work. Improvement plans shall not be submitted until the tentative map has been approved.

(Ord. No. 1608, §2)

The County Engineer shall review improvement plans duly submitted to him or her. He or she shall approve and sign them if, and only if, they fully comply with the requirements of the Subdivision Map Act and this Chapter, and substantially comply with the tentative map. Any changes from data shown on the tentative map relative to road and storm drains shall be supported by an engineering report and will not be allowed unless the County Engineer approves the change.

(Ord. No. 1608, §2)

Improvement plans shall be prepared according to good engineering practice under the direction of, and shall be signed by, a civil engineer registered by the State of California. Improvements shall be designed in compliance with the Solano County Improvement Standards and Specifications. Improvement plans shall be printed or drawn clearly and legibly, or reproduced by a process that results in a permanent record that will permit direct reproductions. Each sheet shall be 24 inches vertically by 36 inches horizontally (610mm x 910mm). Each sheet shall have a marginal line drawn completely around it, leaving an entirely blank margin of one and one-half inches (38 mm) on the left-hand side and one-half inch (13mm) on the other three sides. If the improvement plans include five or more sheets, a key map showing the roads and the area covered by each sheet of the plan shall be included on the first sheet of the plans.

(Ord. No. 1608, §2)

Improvement plans shall also include complete grading plans. Grading plans shall be on sheets separate from the improvement plans, and shall contain a title block and have a graphical scale in addition to a numerical scale. The grading plans may be submitted initially on sheets larger than 24 inches by 36 inches (610mm x 910mm). However, if initial plans are submitted on such larger sheets, the grading plans must be resubmitted with the as-build plans on sheets conforming in size and margin requirements to the remainder of the improvement plans. Grading plans resubmitted at the proper size may be a series of 24 inches by 36 inches (610mm x 910mm) reproducible sheets made with proper overlap and title block from the initially submitted grading plans.

(Ord. No. 1608, §2)

The improvement plans shall show the complete plans, profiles and details for all improvements to be placed in a proposed subdivision including but not limited to, all road work, including road survey monuments, drainage channels and structures, all utilities to be installed by the subdivider including all appurtenances thereto located within the right-of-way, retaining walls or other improvements to support cut slopes and embankments, bridges if constructed in conjunction with subdivision improvements, the location of utilities not within the right-of-way which may control the location and elevations of storm drains and culverts, the location of fire hydrants, curbs, gutters and sidewalks, fences that may be required, gates, structures and drainage facilities necessary to control slides, other improvements which may be required to complete the work, and conditions beyond the subdivision boundaries which affect the integrity of the proposed improvements.

No change shall be made in the improvement plans for the subdivision without prior approval of the County Engineer. All changes approved by the County Engineer shall comply with the requirements of this Chapter.

(Ord. No. 1608, §2)

An estimate of the cost of the improvements to the proposed subdivision shall be prepared by the subdivider and shall accompany the improvement plans each time they are submitted. Cost estimates shall include a separate item for contingencies. The cost of relocating existing utilities and appurtenances should also be included. Upon consideration of the estimate submitted by the subdivider, the County Engineer shall determine the estimated cost for the improvements of the proposed subdivision.
