12.08.010 Borough to maintain dedicated thoroughfares.

The borough shall assume and discharge the obligation of maintaining streets and alleys within the townsite service area in a condition suitable for vehicular traffic only:

A. Within the boundaries of all streets and alleys platted in the townsite service area;

B. Within budget constraints; and

C. Within the boundaries of any streets or alleys subsequently created within the townsite service area by each of the following things being done:

1. The filing of a plat in the office of the recorder at Juneau, Alaska, showing with definiteness and certainty the boundaries of such streets and alleys;

2. The filing of an identical plat with the borough clerk;

3. The formal dedication by the owner of such streets and alleys of the land embraced therein to the public for street purposes, including the construction, repair, and maintenance of water, sewer, electric, telephone, and other utility lines and systems thereon; which dedication must be executed in the manner required for the execution of deeds under state law or as modified herein;

4. The method of financing maintenance is identified;

5. The delivery of such dedication to the planning commission for its acceptance or rejection;

6. The acceptance of such dedication by the planning commission; provided, however, that no streets or alleys shall be constructed, repaired or maintained at borough expense unless specifically authorized by the assembly. No dedication shall be accepted by the borough unless the pattern of the streets and alleys so dedicated is in harmony with the present street and alley pattern of the borough, or is such as to not cause undue inconvenience or expense in providing public services along such streets and alleys. No such dedication shall be accepted unless the width of such streets and alleys conforms to the width of adjoining streets and alleys or as approved by the planning commission.

D. Maintenance of public roads and streets outside of the townsite service area may be provided by a road maintenance service area (RMSA) created by authority of HBC Title 7. The RMSA board shall be responsible for establishing standards of maintenance within that service area.

E. Nonroutine maintenance may be performed on borough roads outside the townsite service area when the manager determines that circumstances exist that hinder the general public interest. The manager shall report occurrences to the assembly. (Ord. 08-03-180)

12.08.020 Improvement of private property.

No borough funds shall be expended for the construction of any sidewalk, curbing, paving, or improvement or repair of any driveway, alley, or other area on private property unless the assembly shall first have entered into a lease with the owner thereof or other satisfactory agreement permitting public use thereof. (Ord. 08-03-180)

12.08.030 Plan of road construction and development.

The streets and alleys of the borough shall be constructed, graded and improved when existing rights-of-way permit it and in accordance with the provisions of this chapter as administered by the manager. It shall be unlawful to destroy, construct, or repair any street, alley, culvert, bridge, sidewalk, ditch, sewer, or drain within the corporate limits of the borough on property within its jurisdiction without first obtaining permission from the manager. (Ord. 08-03-180)

12.08.040 Standards applicable.

All public access roads in the Haines Borough must be constructed in accordance with an approved plat and meet or exceed the requirements set forth in this section or in accordance with a variance granted by the planning commission due to extenuating circumstances. (Ord. 08-03-180)

12.08.050 Local road construction standards.

The borough adopts the standards for construction of roads contained in this chapter. Should there be a conflict between the road construction standards contained herein and those contained in the subdivision ordinance (Chapter 18.100 HBC) or other chapters of the borough code, these standards shall control. (Ord. 08-03-180)

12.08.060 Other requirements not eliminated.

This chapter only establishes design and construction standards and does not eliminate any other requirements that may be established by federal or state statutes, borough ordinances or other regulations adopted pursuant to these laws. Permits may be required in instances involving construction in flood hazard zones, wetlands and fish habitat. Grading, excavation and fill permits, and storm water/water separation waivers may be required. The land owner is responsible for knowing the necessity of a permit and acquiring it.

12.08.070 Road construction standards – Introduction.

A. Enforcement. The borough shall inspect road construction to ensure adherence to an approved plat and borough standards. Inspection may include test holes; engineering analysis of road geometry, drainage, and general adequacy for anticipated traffic. Construction not adhering to an approved design or construction standards shall be brought into compliance by the developer.

B. Design Speeds. All categories of roads named in this chapter have a statutory speed designation of 25 miles per hour for residential areas, except that collector roads may enjoy 35 miles per hour. Actual speed design will be determined by factors of terrain and construction costs. The posted speed may be lower than the design speed, and shall be set by the municipality with due consideration to neighborhood safety; presence of schools, houses, parks and crosswalks; the presence of driveways, parked vehicles and multiple turn locations and the effectiveness of enforcement. (Ord. 08-03-180)

12.08.080 Road construction standards – Construction categories.

A. Internal Subdivision Roads. The standard to which a road is constructed shall be based on the categories set forth below. The category shall also be determined by lots indirectly served where the road is a collector or subcollector and provides necessary access to lots not otherwise served by a collector or sub-collector.

Category I:

A cul-de-sac road or other minor road that serves less than 20 lots.

Category II:

A road that serves between 20 and 39 lots.

Category III:

A road that serves 40 or more lots.

B. Category Determination. The borough will determine the category of road based on the standards set forth in this chapter. If the developer disagrees with the category the applicant may request a review by the manager.

C. Existing Collector Roads. Existing collector roads shall be reconstructed to a Category III in a new subdivision, where the average daily traffic (ADT) on the existing collector road can be projected to exceed 300 after subdivision. Alaska Department of Transportation and Public Facilities Division of Planning, Mapping Section current ADT readings shall be referenced.

D. Half-Streets. Where a previous dedicated half-street exists in a subdivision adjacent to a new subdivision, the second half of the street within the proposed subdivision shall be dedicated to the borough for public use by the subdivider. (Ord. 08-03-180)
