The property owner shall make an agreement with the City on the road improvements to be constructed by him/her. These road improvements shall include curb, gutter, sidewalk, necessary longitudinal storm drainage and the necessary structural pavement section. The City Engineer shall specify the structure design of the pavement section. The property owner may be required to repave one-half of the streets to the adopted center line of the street under the direction of the City Engineer in order to insure restoration of the street to its proper function. Street lighting where reasonably necessary shall be considered as a part of the improvements.
The City Engineer may approve and allow such variations and deviations from the requirements of this chapter, as he/she determines are made necessary by the conditions of the terrain and the existing improvements in the immediate vicinity of the property and lot involved.
The City Engineer shall review the road widths shown on the City Major Roads Plan at the time of application, to determine their adequacy to serve the traffic generated by the proposed land use, adjacent land uses, and any other changes to the General Plan made by the adoption of the City Major Roads Plan; and his/her findings thereon shall become the requirements for dedication of right-of-way and the construction of improvements.
The City Engineer shall control access to roads, as to location, size, type, and number of driveways, so as to safely permit ingress and egress and so as to comply with standards and policy of the Engineering Department and this chapter.
When the City Engineer determines that this chapter is applicable to any building permit application, he/she shall inform the permit applicant of his/her determination and findings as to the specific requirements of this chapter applicable thereto and of the availability and procedure for appeal of his/her determination to the Planning Commission.
Acceptance of a building permit by an applicant after determination by the City Engineer that the provisions of this chapter are applicable shall constitute an agreement on behalf of the applicant and owner, their heirs, successors and assigns, to comply with all the terms and conditions imposed by the City Engineer’s findings, this chapter, and all other applicable ordinances and statutes.
a.
Costs. Upon proper written application to the City Council and investigation and recommendation to the Council by the City Engineer, the City may contribute to the costs of making any improvements required by this chapter, if the City Engineer determines that they are excessive due to topography or other natural causes or will greatly exceed the costs of other property owners in the immediate vicinity who are required to make improvements hereunder.
b.
Plans. The applicant shall provide plans showing line and grade, and shall place one set of construction stakes. If the City Engineer cannot provide plans or survey stakes in time to coordinate with the applicant’s schedule, the applicant will furnish construction plans for review and approval by the City Engineer before construction starts. The construction plans shall be prepared by a California Licensed Civil Engineer and shall be in accordance with the applicable sections of the Grading and Subdivision regulations of the Municipal Code.
Whenever uncertainty exists as to the proper application of this chapter in the matter of street alignment, the City Engineer shall determine its application in conformity with the spirit and intent of this chapter.
On a lot which is affected by road widening required by the provisions of this chapter, all required yards, setbacks, parking area, loading space, and building locations for new buildings or structures or additions to buildings or structures, shall be measured and calculated from the new lot lines being created by the widening; but, for the purpose of establishing the required front yard depth on a frontage where the ultimate curb line has been determined under the provisions of this chapter, the depths of all existing front yards may be measured from such ultimate curb line instead of the front lot line. In applying all other provisions of this Code, the area of such lot shall be considered as that which existed immediately before to such required road widening.
a.
Surfacing of Pedestrian Paths. Pedestrian paths shall be surfaced with the same material of the same thickness specified below for sidewalks and for a width of at least five feet.

The one mile distance shall be measured along the shortest pedestrian route available or planned, measured from the closest boundary of the school site and subdivision;
3)
Along all streets wherein the area is zoned R-12 or in land use districts having a higher density;
4)
Along all streets within any portion of a subdivision zoned for multiple family, business, or commercial land uses.
