Guam § 62501 - Required Improvements.

§ 62501. Required Improvements.

The subdivider shall provide the following improvements

and improvement areas within time limits specified by the

Commission:

(a) Streets, Alleys and Sidewalks - Urban areas. Where

general plans have been or are hereafter duly adopted and show

an area as planned for development into urban use, the following

street, alley and sidewalk improvements shall be required:

All streets and alleys within the subdivision shall be graded

and drained the full width of the right-of-way. The roadbed

portion of the right-of-way shall be improved with a stabilized

coral base and surfaced with light bituminous surface treatment

having a minimum width of twenty-two feet (22'). The roadway

centerline gradient and right of way cross-section including

drainage ditches, travelled roadway design and paving and

shoulders shall be in conformity to criteria established by the

Commission.

Permanent sidewalks having a minimum width of four feet

(4') shall be laid out for all streets and shall be dedicated to the

government of Guam. The Commission shall establish criteria

relating to width and construction of such sidewalks, and all such

sidewalks shall be in conformity thereto.

(b) Streets and Alleys - Unplanned Areas. Where at the time

of a subdivision a general plan has not been adopted or where the

general plan designates the area as agricultural, the following

street and alley improvements will be required:

All streets and alleys within the subdivision shall be graded

and drained the full width of the right-of-way. The roadbed

portion of the right-of-way shall be improved with a stabilized

coral base. The roadway centerline gradient and right-of-way

cross-section including drainage ditches, travelled roadway and

shoulders shall be in conformity to criteria established by the

Commission.

(c) Storm Water Drainage. Storm drainage facilities shall be

provided in all subdivisions in accordance with plans prepared by

the subdivider conforming to criteria established by the

Commission. These facilities shall be designed to dispose of

normal storm waters falling on the subdivision without hazard of

flooding, inconvenience of ponding, and the erosion of public or

private lands.

(d) Domestic Water. Potable domestic water shall be piped

onto each lot within the subdivision. Water pipes shall be new and

so sized to supply normal household pressures.

(e) Sanitary Sewage Disposal. When sanitary sewers are

provided in a subdivision, they shall be in conformity to plans

prepared by the subdivider satisfactory to the Commission. When

sewers are placed within a subdivision, the minimum permissible

lot size shall be as determined by the applied zoning district, or in

the absence of zoning, shall be not less than seven thousand

(7,000) square feet. In subdivisions where sanitary sewers are not

provided, the minimum permissible lot size shall be determined

by the slope and characteristics of the subdivision soil and subsoil

but in no event shall be less than is established by the applied

zoning district, or in the absence of zoning, seven thousand

(7,000) square feet. Determination of lot size shall be made on the

basis of soil percolation tests made in conformity to standards

adopted by the Commission. Lot sizes, including area and

minimum widths and depths shall be related to the ability of the

subdivision lands to accept the anticipated septic tank effluent

whereby no sanitary problem will be created. The Commission

shall establish criteria relating lot sizes and shapes to tested rates

of seepage, and all lots created after the enactment of this Chapter

shall conform thereto.

(f) Survey Monuments. Permanent concrete monuments shall

be installed at all points of direction changed in the subdivision

perimeter and in the exterior lines of blocks.
