b. The City shall require new subdivisions to dedicate the rights-of-way according to the widths specified in Section 11.04.060(f) below, according to the appropriate functional classification. Arterials and collectors are as designated in the Master Roads and Streets Plan. This provision may be waived on a case-by-case basis by the Director of Public Works by requiring a minimum dedicated right-of-way of sixty feet along with an expanded building setback of sufficient width to equal the rights-of-way widths specified in Section 11.04.060(f).
c. The Planning Commission shall require the dedication of a half street if the other half of the street has been dedicated or can reasonably be expected to be dedicated, unless it determines the street would be unnecessary or undesirable. It shall further require half-street dedications if the street is on the Master Plan for Roads and Streets map as a planned improvement of is the logical existing street.
d. When a subdivision boarders or contains a street designated an arterial on the Master Plan map, the Homer Advisory Planning commission may require shared access or the dedication of a frontage street. Alternatively, an interior road may be required (along the rear lot lines of the lots abutting the arterial) which will serve the access requirements of all the lots fronting the arterial. (Ord. 10-57 §4 (part), 2011; Ord. 87-6 1(part), 1987; Ord. 85-14 (part), 1985).
11.04.050 Master Roads and Streets Plan--Adopted. a. The City hereby adopts the functional classification system, Master Plan map, and preliminary plans and profiles of future streets contained in the Master Roads and Streets Plan.
b. In all new subdivisions, excepting those specifically exempted in Chapter 22.10, the subdivider shall be required to dedicate street rights-of-way designated as arterials or collectors on the Master Plan for Roads and Streets map, in general agreement with the location and geometrics outlined on the map and, if preliminary engineering plans have been prepared, in general accordance with the route layout specified therein. The Planning commission may require adjustments to the proposed plat at the preliminary platting stage if it finds that such geometrics and alignments are not adhered to.
c. If a development includes a segment of an arterial or collector street as shown on the Master Plan, the developer shall construct the streets on the alignment adopted in the Master Roads and Streets Plan, and according to the geometric requirements (maximum grade, curvature, and intersection grade, and minimum intersection curb return radius) conforming to the respective classification. The developer, in such case, shall be required to construct the street to a twenty-eight-foot width in accordance with the minimum requirements of a local residential street; provided, however, that the City may, upon director of the City Council, elect to require construction to the full standards and pay to the developer the cost difference between the required street and the proposed street.
d. The City Council shall be empowered to designate additional routes as arterials and collectors beyond those adopted on the Master Plan map. (Ord. 87-6(S) 1(part), 1987; Ord. 85-14 (part), 1985).
11.04.055 Official Road Maintenance Map--Adopted. a. The "Official Road Maintenance Map of the City of Homer" is enacted by reference and declared to be part of this chapter in its exact form as it exists on the date that the ordinance codified in this chapter is adopted by the City Council. This map shall be kept in the City offices for public inspection.
b. After the effective date of the ordinance codified in this chapter, the City shall not accept maintenance responsibility for any roads, existing or future, which are not constructed or reconstructed to the standards of this chapter, unless such road is shown on the "Official Road Maintenance Map of the City of Homer."
c. City maintenance service, as specified on the official map, shall be provided in two categories:
1. Urban Road Maintenance, level of service for road maintenance on streets that meet the City Standard and these roads are first priority, and
2. Rural Road Maintenance, the level of service for roads that do not meet City standards and are determined to deserve a reduced level of service and these roads take second priority.
d. If the map becomes lost or damaged, the map or significant parts thereof remaining after partial destruction shall be preserved. The City Council may by ordinance enact a new map which shall be consistent with and supersede the old map.
e. The map shall be signed by the City Clerk with a note of the date of enactment by the City Council. Amendments by ordinance shall be immediately added to the "Official Road Maintenance Map of the City of Homer" with a notation of the date of enactment of said ordinance by the City Council.
