Article 8 - Required Improvements and Design Standards

ARTICLE 8. REQUIRED IMPROVEMENTS AND DESIGN STANDARDS

This Article outlines general requirements for subdivision design, which apply to all subdivisions except where otherwise provided in these Regulations. The Subdivision Review Officer may suggest modifications in the subdivision design presented by the Subdivider. The Board of County Commissioners, as a condition for approval, may require modification in the proposed design.

Section 8.1. Surveys/Monuments
8.1.1 Surveys
The Courts require re-surveys to be performed "in the footsteps" of the original surveyor; therefore, original surveys should be performed so as to aid the retracement. Surveys will comply with regulations adopted by the New Mexico Board of Registration for Professional Engineers and Surveyors.

8.1.2 Monuments
Each subdivision shall be monumented so as to define the subdivision and all roads by reference to permanent monuments. N.M.S.A. 1978, § 47-6-3(A)(1) (Repl. 1995), as amended. Monuments shall be located in the ground and made according to the following requirements, but it is not intended or required that monuments be placed within the traveled portion of a road to mark angles in the boundary of the subdivision if the angle points can be readily reestablished by reference to monuments along sides of the roads.

Monuments shall be located in the ground at all angle points in boundaries of the subdivision; at all lot corners; at the intersection lines of roads within the boundaries of the subdivision; at all points of curvature, points of tangency, points of compound curvature, points of reverse curvature and angle points in the side lines of roads, alleys and lots. If the required location of a monument is in an inaccessible place, or where the locating of a monument would be clearly impracticable, it is sufficient to place a reference monument nearby and the precise location thereof be clearly indicated on the plat and referenced to the true point. At least two well-separated subdivision boundary corners shall be set in concrete and so shown on the final plat.

Section 8.2. Subdivision Design
8.2.1 Lot Design
a. Arrangement

The size, shape, and location of all lots shall be such that there will be a minimum of foreseeable difficulties, for reasons of topography, soils, or other conditions, in securing building permits, installing septic systems, or similar development actions.

b. Access

All lots shall front on either a public or private street. Double frontage lots shall, whenever practicable, be avoided.

c. Parking

Each lot shall have adequate space to park two (2) vehicles on the lot.

d. Utility Easements

Access to each parcel by utility easement must be provided.

8.2.2 Block Design
Unless restricted by topographical irregularity or other constraints, all blocks should have sufficient width to provide for two (2) tiers of lots of appropriate depths. The length, width, and shape of all blocks shall be such as are appropriate for the surrounding area and type of development. Generally, blocks should not be greater than two thousand (2,000) feet nor less than four hundred (400) feet in length.

Section 8.3. Streets
8.3.1 Design and Construction
All streets are to be designed and constructed so as to conform to the standards set forth in the San Juan County Road Policy, as amended.

8.3.2 Street Maintenance
No subdivision shall be approved in which streets are not dedicated to the County unless adequate provisions are made by the subdivider for street maintenance. The County may require a performance guarantee or an adequately funded maintenance agreement before approving such a subdivision. See also Section 4.5.6.

8.3.3 Permits
Approval of a subdivision which accesses a State or federal highway in such a manner as to require a permit pursuant to SHTD Rule 89-1(L) or other applicable law or rule, shall require presentation of the proper permit for such access. If a permit has not been issued at the time of final approval, final approval shall be contingent upon the subdivider obtaining the required permit.

Section 8.4. Other Design Considerations
The remaining sections outline additional design considerations. Any design-related item not specifically noted here or elsewhere within these Regulations, shall be designed and constructed to generally accepted standards, after consulting the Subdivision Review Officer and approval of the Board of County Commissioners.

Section 8.5. Irrigation Water in Subdivisions
8.5.1 Requirements
The plat and disclosure statement shall state whether or not irrigation water is being provided to the subdivision, and to which lots it is being provided if only certain lots are to be provided with irrigation water. If irrigation water is provided to the subdivision, the following items shall be required:

a. documentation showing that valid water rights exist for said lots;

b. documentation that the water delivery system is capable of delivering to each parcel of land proposed to be irrigated its share of the irrigation water;

c. show the system through which irrigation water flows in reaching said lots from the river to the lot and show irrigation ditch easements from the main canal to said lots;

d. state whether the lot owner is responsible for system maintenance for water coming to the property and leaving the property; and

e. list any limitations for future division or alienation of water rights for said lots.

8.5.2 Irrigation Canal Setbacks
a. Required setbacks of buildings and other structures and objects which could impede the passage of maintenance equipment shall be the following distances from the centerline of irrigation canals:

b. This limitation of rights-of-way on irrigation canals shall apply only where the canal is built on gently sloped terrain, the slope of which does not exceed 10 percent, or one foot decrease in elevation for each ten feet horizontally. When the canal is located in terrain which has a slope exceeding 10 percent, the downhill right-of-way limitation shall be increased a reasonable amount to accommodate fill for the ditch bank so that the bank may slope, no more steeply than on one (1) foot vertical per 1 1/2 feet horizontal.

c. All subdivisions shall be planned and located so that a building pad is available on each lot whose elevation is at least 1.0 foot above the level of the 100-year flood elevation as previously defined. All roads shall be designed so that they are fully useable during a 25-year storm.

Section 8.6. Fire Protection
8.6.1 Fire Flow Requirements
The following fire flow requirements are applicable to all types of subdivisions, except where otherwise provided in these Regulations. If lot sizes within the subdivision vary, based on the size classification outlined below, the Board of County Commissioners shall determine which classification is applicable.

8.6.2 Small Lots
Small lots, with a lot width at the building line of less than (80) feet wide require delivery of 500 gpm for two (2) hours. Fire hydrants shall be a maximum of 500 feet apart.

8.6.3 Medium Lots
Medium lots, with a lot width at the building line not less than eighty (80) feet wide and not more than two hundred (200) feet wide, and a depth of at least one and one half times the width shall require delivery of 250 gpm for two (2) hours. The maximum spacing requirements for fire hydrants, based on the width of the front lot line, are illustrated below.

Illustration - Fire Hydrant Spacing

Width At Building Line Maximum Spacing
150-200 ft. 1000 ft.

100-150 ft. 750 ft.

8.6.5. Hydrant Piping
All piping connecting hydrants shall be six (6) inches or larger, depending on flow requirements.

8.6.6. Storage Computation
Storage requirements shall be calculated based on the fire flow requirements plus domestic consumption.

8.6.7. Distance Calculation
Distance between fire hydrants shall be calculated along the street right-of-way.

8.6.8. Conflicts
When these requirements conflict with regulations established by a recognized water users association, the more stringent will apply.

Section 8.7. Fencing
Each subdivision adjoining open range, or in an area in which livestock is kept or allowed to remain, shall be contained within a perimeter fence of sufficient character so as to prevent any and all livestock from escaping through any portion of the fence. The perimeter fence shall be tied to the road or highway right-of-way fence. If any right-of-way fence is cut to provide access, the subdivider shall install a cattle guard at the point of the cut or complete all perimeter fencing prior to cutting the right-of-way fence. The subdivider shall have the responsibility of keeping the right-of-way fence intact until each adjoining lot is sold or leased. The subdivider shall be responsible for maintaining the perimeter fence, unless specific provision is made in the disclosure statement assigning this responsibility to the purchaser or lessee.
