16.40.020 Application.
This chapter shall apply as follows:
A. Plats and binding site plans shall be subject to this chapter;
B. The design specifications identified in this chapter shall apply to the design and construction of streets, roads, drainage facilities, sidewalks and other improvements serving plats and binding site plans;
C. No plat or binding site plan shall be granted final approval unless the streets, roads, drainage facilities, sidewalks, and other improvements required by this chapter have been constructed, installed, or provided. (Ord. 1856 § 2 (Exh. B), 2018).
16.40.030 Purpose.
A. Ensure that plats and binding site plans include appropriate provisions for the public health, safety, and general welfare, for open spaces, drainage ways, streets or roads, alleys, other public ways, transit stops, potable water supplies, sanitary wastes, parks and recreation, playgrounds, schools and school grounds, sidewalks, and planning features that assure safe walking conditions for students traveling to and from school;
B. Establish uniform standards for the preparation of plats and binding site plans;
C. Ensure that plats and binding site plans are accurate and consistent with applicable laws and regulations;
D. Establish uniform design standards for the design and construction of streets, roads, drainage facilities, sidewalks, and other infrastructure or improvements within plats and binding site plans.
E. Ensure that streets, roads, drainage facilities, sidewalks, and other improvements serving plats and binding site plans are compatible with, and can be easily connected to, adjoining properties and developments, thereby creating a uniform and interconnected system of public improvements. (Ord. 1856 § 2 (Exh. B), 2018).
16.40.040 Authority.
This chapter is adopted pursuant to chapters 36.70, 36.70A, 36.70B, 58.17 RCW and other applicable laws and regulations. (Ord. 1856 § 2 (Exh. B), 2018).
16.40.050 Access standards.
The design standards in this section shall apply to the design and construction of all plats and binding site plans. Vehicle and pedestrian access shall be provided as follows:
A. General.
1. Plats and binding site plans shall be served by one or more streets providing adequate ingress and egress.
2. The alignment of streets within plats and binding site plans shall conform to the city’s street plan and allow streets adjoining the plat or binding site plan to be extended through the site.
3. Street intersections shall be as nearly at right angles as practicable and in no event shall the angle formed be less than 30 degrees.
4. Street networks shall conform to any applicable fire code requirements to ensure adequate access for emergency vehicles and equipment.
5. Unless warranted by special physical circumstances, the right-of-way for public streets shall be at least 60 feet wide.
6. Alleys shall be at least 16 feet wide plus such additional width as shall be necessary for an adequate turning radius.
7. Public streets, roads, alleys, and sidewalks shall conform to applicable standards identified in chapter 12.28 BMC.
8. Low impact development features such as bioretention areas, rain gardens, and permeable paving shall be incorporated into the design and construction of all streets unless demonstrated to be infeasible through an engineering analysis. In determining the feasibility of such low impact development features, an engineering analysis shall be submitted and reviewed by the city engineer. This analysis should consider site characteristics such as soil and ground water conditions, and anticipated traffic volumes. The analysis should be consistent with the Washington State Department of Ecology’s “Stormwater Manual for Western Washington” and the design and site evaluation guidance in the Puget Sound Partnership’s “Low Impact Development Technical Guidance Manual for Puget Sound.”
9. All streets, bridges, sidewalks, and pedestrian access facilities shall be designed and constructed in accordance with plans and specifications prepared or approved by the city engineer.
10. All dedicated streets shall be graded to their full width with adequate drainage provided prior to acceptance for public use. Grades shall be established by the city engineer and all streets shall be surfaced according to plans and specifications prepared or approved by the city engineer.
B. Private Streets. Vehicle and pedestrian access should be provided by public streets dedicated to the city. However, private streets and shared driveways may, at the city’s discretion, be authorized if all of the following criteria are met:
1. The goals of the zoning code to provide for adequate light, air and usable open space between structures would not be compromised; and
2. The dedication and improvement of a public street is not necessary to facilitate the provision of public utilities such as water, sanitary sewer, storm drainage; and
3. The dedication and improvement of a street is not necessary or desirable in order to provide on-street parking for overflow conditions; and
4. No potential safety hazards would result from multiple access points between existing and future developments onto a roadway without curbs and with limited sight lines; and
5. There is no potential for extending the street system to connect with existing streets, or to serve potential development sites adjacent to the plat or binding site plan; and
6. Private streets shall be designed and constructed in accordance with the applicable standards identified in chapter 17.85 BMC.
C. Sidewalks and Pedestrian Access.
1. Sidewalks and pedestrian access shall be designed and constructed in accordance with the applicable standards identified in chapter 17.85 BMC.
2. Sidewalks should be provided along both sides of streets unless the street adjoins the boundary of the plat or binding site plan and there is no potential for future development along the opposite side of the boundary. (Ord. 1856 § 2 (Exh. B), 2018).
16.40.060 Design of lots and blocks.
A. Blocks.
1. Blocks shall be designed and arranged to provide for the safe and efficient movement of vehicles and pedestrians.
2. Blocks shall be identified on the face of the plat or binding site plan by letters or numbers.
B. Lots.

16.40.070 Utilities.
A. Easements shall be provided for all utilities including storm water facilities.
B. All utility easements shall be designed and configured to allow access for inspection, maintenance, and repair purposes.
C. The design and configuration of easements for storm water and sanitary sewer facilities shall be reviewed and approved by the city engineer.
D. Low impact development techniques shall be incorporated into the design and construction of all plats and binding site plans in accordance with the provisions of chapter 17.70 BMC.
E. All storm water facilities shall be approved by the city engineer and shall be designed and constructed in accordance with the applicable standards identified in BMC Title 14.
F. Above ground utility installations, such as power and telephone lines, shall not be permitted unless the city engineer determines that topographic or geologic conditions make below ground installation infeasible.
G. Each lot in a plat or binding site plan shall be provided with a connection to a public water supply system. Lots used for nonbuilding purposes shall be exempt from this requirement provided a note is included on the face of the plat restricting the use of the lot to nonbuilding purposes.
H. Public water supply systems and connections shall be designed and constructed in accordance with any standards adopted by the Skagit Public Utility District.
I. Each lot in a plat or binding site plan shall be provided with a connection to the city’s sanitary sewer system. Lots used for nonbuilding purposes shall be exempt from this requirement provided a note is included on the face of the plat restricting the use of the lot to nonbuilding purposes.
J. Sewer system components and connections shall be designed and constructed in accordance with any applicable standards adopted by the city of Burlington and shall be approved by the city engineer.
K. Service Mains and Fire Hydrants. Service mains and fire hydrants shall be installed and inspected by the city engineer and fire marshal prior to final approval of plats and binding site plans. The design and construction of service mains and fire hydrants shall be consistent with all applicable standards and regulations, and all plans shall be approved by the city engineer and fire marshal.
