19.28.020 Design, review and approval of improvements. Revised 1/24
A. All public improvements and private streets shall be designed by a civil engineer licensed in the state of Washington and approved by the Land Use Code Administrator. Final approval of plans for public improvements by the Land Use Code Administrator shall constitute approval to commence construction of required public improvements.
B. The Land Use Code Administrator may require changes or modifications to preliminary or approved plans. (Ord 23-602 §3 (Ex B); Ord 01-86 §4 (Ex B)
19.28.030 Design standards for improvements. Revised 1/24
All improvements shall be designed to comply with the following standards:
A. Street improvements shall be constructed in accordance with the City of Quincy Design and Construction Standards.
1. Alignment. Connecting street center lines deflecting from each other at any one point more than ten degrees shall be connected by a curve the radius of which shall be approved by the Municipal Services Director or his/her designee.
2. Classification. Streets shall be classified with reference to the comprehensive plan and official street maps.
3. Dead Ends. Streets designed to have one end closed or terminating in a cul-de-sac shall be provided at the closed end with a turnaround having a right-of-way radius of not less than fifty feet, and such streets in excess of six hundred feet in length shall be avoided.
4. Grades. Gradients on collector or arterial streets shall have a minimum centerline slope of one-half percent. Gradients of more than seven percent shall be approved by the Municipal Services Director or his/her designee.
5. Intersections. Street intersections shall be as nearly at right angles as is practicable, and street jogs having offsets of less than one hundred twenty-five feet between center lines shall be avoided.
6. Location. The street layout of every subdivision shall conform to any adopted comprehensive plan or circulation element thereof, and shall provide for the continuation of major streets which serve property contiguous to the subdivision. Street networks shall be such as to provide ready access for fire and other emergency vehicles to any part of the subdivision. The City Council, upon recommendation of the Hearing Examiner, may require additional access points if such are found necessary to protect the public safety.
7. Standards for Streets and Sidewalks. The minimum standards for streets and sidewalks shall be determined by the following table, unless otherwise specified by the comprehensive plan or any portion thereof.
8. Surfacing. Streets shall be paved with a minimum of three inches asphalt concrete pavement.
9. Subdivision Boundary Streets. A street lying along the boundary of a subdivision may be dedicated with less than the width required by this title if it is practicable to require the dedication of the remaining portion of such width when the adjoining property is subdivided. In such case there is required a reserve strip one foot wide along such street for the purpose of withholding access to the property that is not subdivided from such street until a street is constructed to the full width required. The procedure shall also apply in the case of any street which dead ends at the boundary of a subdivision.
