Wherever feasible, data as set forth in city Tidelands Survey, recorded in the Anchorage Recording Precinct's Record of Plats as Plat C241 shall be used for surveys under this chapter. Where additional data is required the following procedures shall govern:
A. 
Determination of line of mean high tide.
1. 
In the case of a U.S. survey which abuts the tidelands, the U.S. survey being made prior to the date of statehood, the line of mean high tide shall be construed to be either the meander lines established on the seaward side of the U.S. survey or the line as defined under section 25.50.110, whichever is the lower.
2. 
For tidelands surveys abutting any U.S. survey made after the date of statehood or in any location where no uplands survey exists, the line of mean high tide shall be determined by using USC&GS benchmarks, or any other benchmarks which have been established from that source, and tide table datum. The upland boundary need not follow this line in its entire exactness, but may follow in a "meander" or "average" line of mean high tide. Each end of the boundary should be established on the elevations of mean high tide; provided, however, that, where the true line of mean high tide has been altered by fill or artificial accretion, the line of high tide as it existed prior to such alteration shall govern.
3. 
In case no USC&GS benchmark exists within one mile of the property being surveyed, the surveyor may, by using the tide tables for the immediate body of water, and applying tidal readings he or she has taken, determine the line of mean high tide and use it in accordance with subsection A.2 of this subsection. In some cases such as salt flat or mud flat areas where the average grade of the bench is ten percent or less and determining the elevation of the line of mean high tide could create a lengthy horizontal distance, the municipal manager may require that the true line of mean high tide be established, regardless of the distance from a known benchmark.
B. 
Method of establishing side boundary lines. In fixing the side boundary lines, the general rules of extending riparian boundary lines, as outlined by such authors as Rayner, Clark or Brown, shall be followed. If actual occupancy does not match the riparian boundaries, the survey shall be made to include the occupant's holding and not to encroach on the adjoining occupant.
(CAC 10.16.010)
A. 
The final plat submitted under this chapter shall conform substantially to the preliminary layout as approved by the municipal manager.
B. 
The final plat shall be submitted to the municipal manager on good quality tracing cloth, in ink, together with five prints.
C. 
The final plat shall be drawn to scale of one inch equals 100 feet, with an option of using one inch equals 20 or 40 feet, on sheets of one of three sizes: 18 inches by 24 inches, 31½ inches by 34 inches, or 22 inches by 36 inches, unless otherwise approved by the municipal manager. When more than one sheet is required, an index shall be filed showing the entire parcel with the sheets in numerical order, and each sheet shall show the total number, e.g., "sheet 1 of 3." When more than one sheet is submitted, only the last must have the approval blocks, but all sheets must be the same size.
D. 
When the final plat has been approved by the municipal manager, one copy shall be sent, together with the deed to the property, to the magistrate of the recording district in which the tract lies for official recording. Special instructions shall be sent to the magistrate instructing him or her to send the deed to the occupant after recording. One copy of the plat will be returned to the occupant. The original tracing containing the certification by the municipal manager will be retained by the municipality. Prints or duplicate transparencies will be furnished at cost of reproduction.
(CAC 10.16.020)
A. 
Generally. A final plat submitted under this chapter shall include all information required on the preliminary plat.
B. 
Survey. The final plat must represent an actual survey made by a person who has been qualified by the state board of registration for architects, engineers and land surveyors to practice land surveying in the state.
C. 
Additional information. In addition thereto, the following information shall be shown on the final plat:
1. 
Boundary lines of the parcel with length and bearings, which must close within the limits of one to 5,000. If the seaward limits of the survey fall within the mean low tide, the seaward boundary must represent lines actually established by the surveyor.
2. 
All easements as required by the municipality.
3. 
Basis of bearings used.
4. 
A properly labeled legend showing monuments as found or established.
5. 
The course of the shoreline for an additional 400 feet from each side of the survey.
D. 
Monuments.
1. 
Monuments shall consist of a 1½-inch galvanized iron pipe, 30 or more inches long. This pipe shall have a four-inch flange across the bottom and shall be filled with concrete. Firmly emplaced in the concrete at the top shall be a brass or bronze cap. The pipe shall be thoroughly tamped when set. The brass or bronze cap shall have a minimum two-inch diameter across the top and three-fourths-inch by 2½-inch shank. Each cap shall be marked in accordance with the manual of surveying instructions as compiled by the bureau of land management and shall also show the registration number of the surveyor. Where impracticable to set an iron pipe monument, a tablet containing a minimum of 1,000 cubic inches of concrete and a brass or bronze cap marking the actual corner point may be used. Should the point for a corner be in a place which would be impracticable to monument, witness corners shall be set in a safe place on the survey boundary line or have two reference monuments set. The monuments on the uplands side of the survey shall be referenced to bearing objects, such as trees, rocks, pilings, buildings, etc., or have two reference monuments set marking the corner. These references may be shown on the plat of survey or may be listed separately on a plat as described in subsection C of this section.
2. 
Unless otherwise approved by the municipal manager, every survey shall have at least four monuments, each fully described in the plat of survey. It is desirable but not mandatory that monuments be set at all exterior angle points of the parcel. The line of sight between adjacent monuments shall be unobstructed. The distance and bearing between monuments shall be shown. The distance between adjacent monuments shall not exceed 1,320 feet. No part of the parcel shall be farther than 1,320 feet from a monument unless otherwise approved by the municipal manager.
3. 
If the point for the seaward corner falls in an unsafe place, a witness corner shall be established on the side boundary line.
E. 
Relationship to known monuments.
1. 
Bearings of all lines shall be referred to the true meridian. The magnetic needle may not be used for this purpose. Bearings shall be obtained by deflection from existing official surveys at the GLO, BLM, USC&GS, USGS, the state division of lands, or monuments with proper identification which are delineated on recorded plats, unless otherwise provided for in this chapter.
2. 
True bearings and distances to the nearest established survey lines, such as those listed in subsection E.1 of this subsection, which shall be accurately described on the plat, shall be shown.
