18.100.050 Long plat procedures – Preliminary plat.
A. Planning Commission Review. Before submitting a final plat for approval for recording under AS 40.15, as amended from time to time, and HBC 18.100.112, and unless following the procedures of HBC 18.100.030 and 18.100.035, the subdivider shall submit a preliminary plat prepared by a registered land surveyor to the commission at 20 percent to 35 percent completion in order that general agreement may be reached on layout and arrangement of streets and lots and other public utilities before a final plat is prepared. A 100 percent complete preliminary plat must be submitted to the planning commission for review and approval before any construction begins. Any subsequent changes to the approved preliminary plat must be preapproved in writing by the borough manager. Substantial changes, such as changes to the alignment and grade of roads, changes to water and sewer lines, changes to lot size, or any changes that will cause future expense to the borough, must be approved by the planning commission.
B. Planning Commission Action. The commission shall process preliminary plats pursuant to the standards set forth for special conditions permits and the standards set forth in this chapter.
C. Engineering Standards. The preliminary plat shall be drawn with waterproof nonfading black ink or legibly drawn with pencil on tracing cloth, or tracing paper of good quality, measuring 24 inches by 36 inches, at a scale of either 40, 50, 60 or 100 feet to an inch, scaled appropriately for the size of the property being platted, and shall show accurately on its face:
1. The date, scale and north point.
2. The proposed subdivision name, which shall not be so similar to the name of any plat previously recorded in the area as to cause confusion.
3. The name and address of the owner, the subdivider, and the surveyor preparing the plat.
4. The exact length and bearing of the exterior boundaries of the subdivision.
5. Location and names of adjacent subdivisions and the owners of adjoining parcels of unsubdivided land.
6. Zoning on and adjacent to the subdivision.
7. Location, widths and names of all existing and platted streets, alleys, or other public ways and easements, driveways, and utility rights-of-way, tideland leases, parks, cemeteries, watercourses, drainage ditches, permanent buildings, bridges, and other pertinent data.
8. The water elevations of adjoining lakes or streams at the date of the survey and the approximate high and low water elevations of adjoining lakes, streams and tidal areas.
9. If the subdivision borders a lake or stream, the distances and bearing on a meander line established not less than 20 feet back from the mean high higher water mark of the lake or stream.
10. The location of significant natural features such as, but not limited to anadromous fish streams, existing material sites, wetlands, and U.S. Fish and Wildlife cataloged eagle nesting trees.
11. Layout, width and grades of all new streets, driveways, and rights-of-way, such as alleys, highways, easements for sewers, water mains and other public utilities.
12. Dimensions and areas of lots.
13. Proposed building lines.
14. Radii of all curves and length of tangents.
15. Contours at two-foot vertical intervals or at more frequent intervals if required by the commission for land of unusual terrain characteristics. All pertinent elevations should be shown.
16. The location of any hazard areas set forth in HBC 18.60.010.
17. Plan sheets of the same scale showing engineering design, both plan and profile, and stamped by a registered professional engineer, of any water, sewer, streets, drainage systems, snow storage sites or other public utility to be considered as part of the development.
18. The area for which such data is to be shown shall extend beyond the boundaries of the actual property being platted a distance sufficient to adequately relate the plat to its surroundings.
19. A minimum of six sets of all plan sheets shall be provided to the commission.
D. Approval of Preliminary Plat. The completed application for approval of the preliminary plat shall be submitted to the manager and placed on the agenda for the next planning commission meeting. Approval of properly prepared preliminary plats shall occur no later than 30 days after submission to the commission. If the commission does not approve of the plat within 30 days of filing, they shall return the plat to the applicant for modification or correction. Once properly resubmitted with all required information, the commission shall again have 30 days for review and decision. An applicant for plat approval may consent to an extension of the period for action by the commission. Any reason for disapproval shall be so stated upon the records of the commission and provided to the applicant.
E. Forwarding of Approved Preliminary Plat. Upon commission approval of a properly submitted preliminary plat, the applicant shall follow the final plat procedures below.
F. Action Following Approval of Preliminary Plat. Upon approval of the preliminary plat, the applicant may undertake certain activities prior to approval of the final plat. These activities are:
1. Completing surveying and monumentation;
2. Complying with plat conditions required by the commission as conditions of approval, including but not limited to physical improvements to the property such as land clearing, installation of drainage and identification of rights-of-way and easements.
3. Preparing a reproducible mylar plat as approved by the commission.
G. Nullification of Preliminary Plat Approval. Preliminary plat approval shall become nullified if the applicant has not begun surveying and monumenting the lot lines for subdividing the parcel within 24 months of the approval of the preliminary plat. (Ord. 12-04-284 § 4; Ord. 08-06-184)
