In order to ensure a functional and efficient design, reduce conflicts with transportation facilities, and create desirable lots for development, all activities regulated under this title shall comply with the following requirements:

A. Lot Design.

1. All lots shall meet the minimum requirements of the zoning ordinance, LMC Title 21, for the zone in which the property is located with respect to area, depth, width at street right-of-way, width at building line, yards, percentage of coverage, and, if applicable, parking and loading.

2. All lots shall be provided direct access from a dedicated public street by means of minimum frontage on a public street right-of-way or by a private road.

3. In general, lots and streets should be designed so that no residential property has direct driveway access to a principal arterial. Direct driveway access to minor arterials and collectors shall be minimized. Where driveway access from a principal, minor, or collector arterial may be necessary for two or more adjoining lots, said lots may be required to be served by a common driveway in order to limit possible traffic hazards.

4. Where lots are more than double the minimum size required for the zone, the subdivider may be required to arrange lots so as to allow further subdivision and the opening of future streets to serve potential lots.

5. In general, side lot lines shall be at right angles to street lines (or radial to curving street lines) unless variation from this rule will provide a better street or lot pattern.

6. Lots shall be laid out to provide drainage away from all buildings, and individual lot drainage shall be coordinated with the storm drainage pattern for the area. In general, drainage shall be designed to avoid concentration of stormwater from one lot onto an adjacent lot.

7. In general, the ratio of the depth of any lot to its width shall not be greater than two and one-half to one.

8. Lots having frontage on two streets shall be avoided wherever possible.

9. A panhandle may count toward the lot area and any dimensional requirement for the lot from which the panhandle extends when serving as access to only that lot.

10. In order to encourage sharing of private roads, the area of a private road may be divided evenly between the lots using that private road for access in order to meet lot area requirements. A private road may be used to meet any dimensional requirement for a lot that uses that private road for access.

B. Blocks shall meet the following requirements:

1. The length of blocks shall not exceed 1,320 feet;

2. In any block exceeding 500 feet in length, walks or pedestrian ways at a mid-block point shall be required in order to encourage walking in between residential subdivisions. Pedestrian walkways may be required to provide circulation or access to school, playgrounds, shopping centers, etc. The walks or pedestrian ways shall be provided in a public easement which shall be at least 10 feet in width and designed to the specifications of the public works director;

3. Lots and blocks intended for commercial and industrial use shall be designed specifically for such purposes, with adequate space provided for off-street parking, loading, and delivery. In order to assist review of the proposed development, the hearing examiner may require a preliminary site plan, a preliminary floor plan, or a preliminary landscaping plan to ensure that the platted area is adequate and will not create a need for future variances;

4. The hearing examiner may grant an exception to the requirements of this subsection if it finds that complying with these requirements would result in improved traffic calming and/or pedestrian circulation.

C. Private Roads.

1. Any road surface not open to general public use shall be retained permanently as a privately owned and privately maintained road. This may be accomplished by creating a private tract or easement for ingress and egress purposes.

2. The covenants of any plat containing a private road shall bear the following language:

Warning: Lynnwood has no responsibility to build, improve, maintain, or otherwise service the private roads contained within or providing service to the property described in this plat.

3. Privately owned roads shall be open for necessary public use (emergency and utility access) as determined by the city of Lynnwood.

4. Private roads shall meet the following:

a. The tract or easement and driving surface shall be a minimum of 20 feet wide. When serving a single lot, the tract or easement and driving surface may be reduced to minimum of 15 feet wide with approval by the public works director and fire marshal. Where a lot is served by a private road with a reduced width, fire suppression sprinklers shall be installed at any residence built at such lot. The design of the sprinklers shall be subject to approval of the fire marshal;

b. No parking shall be permitted on the private road serving two or more lots. A “No Parking” sign shall be posted in accordance with city standards and at the owner’s expense;

c. Addresses of all residences shall be posted at the intersection of the private road and the public street, subject to staff approval.

5. All roads within a plat shall meet city construction standards for private roads.

6. Private roads shall serve no more than four lots and not exceed 300 feet in length unless approved by the public works director and fire marshal.

7. A workable turnaround shall be provided in conformance to the standards of the fire department and public works department.

8. A private maintenance agreement shall be required for any private road serving two or more lots.

9. All private roads shall meet the access control guidelines within Ordinance 2968, or any subsequent ordinance. (Ord. 3311 § 5, 2018; Ord. 3192 § 2, 2016; Ord. 2463 § 9, 2003; Ord. 2161 § 1, 1997; Ord. 1314 § 9, 1983)
