(Ord. 1159 NS § 1, 1997)
A. 
No land division shall be approved unless the area to be subdivided shall have frontage on and access from a street approved by the city. Such a street shall be suitably improved by the subdivider, as required by the city, or be secured by a performance bond as provided Chapter 16.32 CMC, with pavement width and right-of-way width as required by these land division regulations.
B. 
Wherever the area to be subdivided is to utilize existing street frontage, such street may be required to be improved as provided for in subsection (F)(3) of this section and CMC § 16.16.070.
C. 
Topography and Arrangement.
1. 
Streets shall be related to the topography of the site. All streets shall be arranged to obtain as many as possible of the building sites at or above the grades of the streets. However, a combination of steep grades and sharp curves should be avoided. The specific standards for design of streets are contained in subsections E and F of this section.
2. 
All streets shall be integrated with the existing and proposed system of traffic circulation as contained in the comprehensive plan.
3. 
Streets shall be properly designed relative to their classification and the standards for that classification in the comprehensive plan, and considering heavy traffic generators such as industries, business districts, schools, churches and shopping centers, population densities, and existing and proposed land use patterns.
4. 
Rectangular grid street patterns are encouraged, but need not necessarily be adhered to, when such a pattern will adversely affect sensitive natural resources.
5. 
Proposed streets shall be extended to the boundary lines of the tract to be subdivided, unless prevented by physical characteristics of the site, or unless in the opinion of the city such extension is unnecessary or undesirable. Dead-end streets shall meet the requirements of subsection E of this section (Street Construction and Dead-End Streets).
D. 
Access to Arterials. Where a land division borders on or contains an existing or proposed arterial, the subdivider may be required to limit access to such streets by one of the following means:
1. 
The division of lots so as to back onto the arterial and front onto a local street, no access shall be provided from the arterial, and screening may be required along the rear property line of such lots;
2. 
Inclusion of a series of cul-de-sacs, U-shaped streets, or short loops entered from and designed generally at right angles to such an arterial street, with the rear lines of lots adjacent to said street abutting the arterial;
3. 
Provision of a marginal access or service road (separated from the arterial by a grass strip and having access thereto at suitable points).
E. 
Street Construction and Dead-End Streets.
1. 
The arrangement of streets shall provide for the continuation of principal streets between adjacent properties for the convenient movement of traffic, for effective fire protection, for efficient provision of utilities and in conformance with the comprehensive plan. If the property adjacent to a subdivision is undeveloped, and a street must be a dead-end street temporarily, the right-of-way shall be extended to the property line. A temporary T- or L-shaped turnaround shall be provided on all temporary dead-end streets, with a notation on the final plat that land outside the normal street right-of-way shall revert to the abutting property owners when the street is continued.
2. 
A cul-de-sac turnaround shall be provided at the end of a permanent dead-end street in accordance with the standards and specifications of subsection F of this section.
F. 
Design Standards. In order to provide for streets of suitable location, width, and improvements to accommodate prospective traffic and afford satisfactory access to police, fire-fighting, snow removal, sanitation, and street maintenance equipment, and to coordinate streets so as to compose a convenient system and avoid undue hardships to adjacent properties, the following design standards are hereby established (street classification shall be as shown in the comprehensive plan, except if a street is not classified, the classification shall be determined by the planning commission in conjunction with the city street superintendent).

Private Streets.
a. 
Private streets may be permitted, as approved, for residential proposals only, and meet the standards based on the proposed type of access (partially adapted from the Stevens County Code, Title 3, standards for private roads):
i. 
Divisions of land with four or fewer parcels, with no public access, may be constructed as a private driveway.
(A) 
There must be a perpetual access easement granted at a width approved by the city. Applicable city development standards will apply, as measured from the edge of the easement.
(B) 
The surfaced area must be developed at a minimum of 20 feet, using crushed or screened gravel top course over base rock and crowned for surface water runoff control.
ii. 
Divisions of land with five or more parcels shall be constructed to minimum standards to accommodate public access and possible upgrade to full city standards if public dedication should occur.
(A) 
There must be a perpetual access easement granted at a width approved by the city. Applicable city development standards will apply, as measured from the edge of the easement.
(B) 
The surfaced area must be developed with base rock and covered with asphaltic concrete pavement (ACP), concrete, or bituminus surface treatment (BST); crowned with drainage ditches to channel surface water runoff; and culverts installed, where existing streambeds traverse the access easements.
iii. 
All other design standards must meet the specific elements as outlined for local or residential in subsection (F)(1) of this section.
3. 
Road Surfacing and Improvements.
a. 
After sewer and water utilities have been installed, the subdivider shall construct streets to the width prescribed above. Streets shall have 12 inches of bank-run ballast and four inches of top course and two inches Class B plant-mix asphalt or better. Adequate provision shall be made for culverts, drains and bridges, as determined by the city.
b. 
Construction materials and methods shall be in accordance with "Standards and Specifications for Municipal Public Works Construction," prepared by the American Public Works Association (APWA), unless otherwise approved by the city.
4. 
Right-of-way widths in excess of those specified in these regulations may be required when, due to topography, additional width is necessary to provide adequate earth slopes. Such slopes shall not be in excess of three to one.
5. 
Intersections.
a. 
Streets shall be designed so as to intersect as nearly as possible at right angles. A proposed intersection of two streets at an angle of less than 70 degrees shall not be permitted. No more than two streets shall intersect at any point unless specifically approved by the city.
b. 
Proposed new intersections along one side of an existing street shall, whenever practicable, coincide with any existing intersection on the opposite side of said street. Street jogs with centerline offsets of less than 125 feet shall not be permitted without specific approval of the city (see Figure 1).* Where an intersection occurs at a principal or minor arterial, street alignment shall be continued and such intersections shall be at least 800 feet apart unless otherwise approved by city.
c. 
Intersections shall be designed with a flat grade wherever practical. In areas of variable topography, a leveling area shall be provided having not greater than a two percent rate of slope at a distance of 60 feet, measured from the nearest right-of-way line of the intersecting street.
d. 
Where any intersection will involve earth bank or existing vegetation inside any lot that would create a potential traffic hazard by obstructing visibility, the subdivider shall cut each earth bank and/or vegetation in connection with the grading of the public right-of-way to conform to the "sight visibility triangle," as described in CMC § 17.64.010.
G. 
Street Dedications and Reservations.
1. 
Street systems in new land divisions shall be designed to eliminate or avoid new half-streets. Where an existing half-street is adjacent to a new land division, the other half of the street lying within the boundaries of the property being divided shall be improved and dedicated by the subdivider. The planning commission may permit a new perimeter street when the subdivider improves and dedicates the entire required street right-of-way width within the land division boundaries.
2. 
Where a land division borders an existing narrow street or when the comprehensive plan indicates plans for realignment or widening of a street that would require use of some of the land in the land division, the applicant may be required to improve and dedicate at his/her expense such areas for widening or realignment of such streets. Such streets shall be improved and dedicated to the full width as required by these land division regulations.
3. 
Sharing of expenses for the improvement of a street which is not of primary benefit to the subdivider shall be fixed by special agreement between the city council and the subdivider. If it is determined that the necessary improvements are due solely to the proposed subdivision the subdivider shall insure the required improvements are made at his/her own expense.
(Ord. 1159 NS § 1, 1997; Ord. 1488 NS § 5, 2012)

(Ord. 1159 NS § 1, 1997)
A. 
All subdivisions shall be connected to the city water system. If water cannot be adequately supplied by the city, a proposed subdivision may be rejected until such time as necessary modifications to the city water system are made as will allow an adequate water supply. As a condition of subdivision approval, the city may require that the costs of modifications be borne by the subdivider.

D. 
All new development shall provide on-site detention and treatment of stormwater so that the volume of water leaving the site is not increased and the quality decreased as a result of development.
E. 
Erosion and sediment control plans shall be incorporated into the development plan as approved by the city. Plans shall include best management practices, which are physical, structural, and managerial practices that prevent or reduce erosion.
(Ord. 1159 NS § 1, 1997; Ord. 1488 NS § 7, 2012)
A. 
The subdivider shall install sanitary sewer facilities to all lots in accordance with the American Public Works Association (APWA) Standards, or as required and approved by the city and any other appropriate agencies.
B. 
Sanitary sewers shall be installed to serve every lot. No individual disposal systems or treatment plants shall be permitted. If sewer facilities cannot practically be installed, a proposed subdivision may be rejected until such time as necessary modifications to the city sewer system are made as will allow for the proper sewer service. As a condition of subdivision approval, the city may require the costs of modifications be borne by the subdivider.
C. 
No sewer main shall be less than eight inches in diameter unless justified and approved by the city water/sewer superintendent and the Washington State Department of Ecology.

(Ord. 1159 NS § 1, 1997)
A. 
All utility facilities including, but not limited to, gas, electricity, telephone, and television cable lines shall be located underground throughout a subdivision. Underground service connections to the property line of each platted lot shall be installed at the subdivider's expense.
B. 
All utility easements and alleys, existing and proposed, throughout the subdivision shall be shown on the preliminary plat. Proper coordination shall be established between the subdivider, the city and various utility companies for the establishment of alleys or easements within the subdivision.
(Ord. 1159 NS § 1, 1997)
A. 
The subdivider may be required to dedicate land, or contribute money in lieu of land, for park and recreation purposes in accordance with the following provisions established under RCW 82.02.020:
1. 
The city may require the dedication of land within the subdivision for park or recreation purposes upon a demonstration that the required dedication is reasonably necessary as a direct result of the proposed subdivision to which the dedication of land is to apply.
2. 
Voluntary agreements between the subdivider and the city that allow payment in lieu of a dedication of land or to mitigate a direct impact that has been identified as a consequence of a proposed subdivision are permitted; provided, that such voluntary agreement shall be subject to the following provisions:
a. 
The payment shall be held in a reserve account and may only be expended to fund a capital improvement agreed upon by the parties to mitigate the identified, direct impact;
b. 
The payment shall be expended in all cases within five years of collection; and
c. 
Any payment not so expended shall be refunded with interest at the rate applied to judgments to the property owners of record at the time of the refund; however, if the payment is not expended within five years due to delay attributable to the developer, the payment shall be refunded without interest.
d. 
The city shall not require any payment as part of such voluntary agreement which the city cannot establish as being reasonably necessary as a direct result of the proposed subdivision.
B. 
In the event that the planning commission determines that a dedication of land is reasonably necessary as a direct result of the proposed subdivision, such dedication shall be of suitable size, dimension, topography and general character for the purposes determined necessary by the planning commission, and shall be shown on the preliminary plat prior to approval.
1. 
Dedication of Land.
a. 
When land within a residential subdivision is required to be dedicated to the city for park or recreation purposes, such land shall be dedicated in accordance with the following standards:
Number of Lots Within Subdivision
Area Required to Be Dedicated
Less than 5
None
5 – 10
1,000 square feet per lot
11 – 20
1,000 square feet per lot
21 – 30
8 percent of total area of subdivision but not less than 25,000 square feet
31 – 40
8 percent of total area of subdivision but not less than 35,000 square feet
41 – 50
8 percent of total area of subdivision but not less than 1 acre
More than 50
8 percent of total area of subdivision but not less than 2 acres
b. 
When the area required to be dedicated is less than two acres, the city may require the dedicated land be located at a suitable location on an edge of the subdivision so that additional land may be added at such time as the adjacent land is subdivided.
2. 
When an existing park is located within one-quarter mile of a proposed subdivision, the subdivider may be required to contribute money to a park improvement fund in lieu of dedication of land. The moneys contributed shall be used by the city in accordance with the requirements of subsection B of this section. Money contributed shall be based on the following formula:
The assessed value, as determined by the Stevens County Assessor, of 1,000 square feet of undeveloped land suited to homesite development in the area of the subdivision, multiplied by the number of times the total area of the subdivision is divisible by the required minimum lot size of the zone in which it is located, less a credit for land actually dedicated for recreational purposes, if any. Example:
Area of Land Division in Square Feet:
10 acres x 43,560 square feet = 435,600 square feet
Area Divided by Minimum Lot Size in Zone:
435,600 square feet/7,200 square feet = 60.5
Area Times Assessed Value:
60.5 x Assessed Value = Required Money Contribution
3. 
The provisions and standards in this section are minimum standards. None of the subsections or paragraphs above shall prohibit a subdivider from dedicating land for recreation purposes in excess of the requirements of this title.
