SURVEYING PLAT

You will prepare a master plan and preliminary plat for your subdivision. You will need preliminary information that shows:

1) Location of existing features and topography (info from topo map, quad sheet, or aerial photos is acceptable). State which quad sheet your project falls in. You can use Google Earth or some other Internet application to find this data.

2) To the above, add the locations of proposed lot lines. Also show the location of proposed roads, including road type and width. If you are proposing sidewalks, bike paths, etc., show the location of these as well. YOU ARE EXPECTED TO HAVE AT LEAST 40 LOTS. If problems arise, see the instructor. Dimension the outer boundary of the subdivision, but you need not dimension lots (that goes onto the final plat).

3) Existing and proposed road and street names. Be sure to label proposed roads and streets as “PROPOSED.” Any proposed names for parks, etc. must also be noted. USE ACCEPTABLE NAMES ONLY. THERE SHOULD BE NO DOUBLE-FRONTAGE

LOTS UNLESS ONE OF THE STREETS FRONTING THE LOTS IS A MAJOR ARTERY WITH NO ACCESS FROM THAT ARTERY.

4) Existing and proposed utility easements. These may be within the road or street easement, BUT MUST BE NOTED AS SUCH on the preliminary plat.

5) Approximate location of proposed buildings (chose 2-3 floor plans as a basis for buildings). THIS ONLY NEEDS TO BE DONE ON THREE OR FOUR LOTS. Building plans may be from any source. You can measure your own or someone else's house to come up with floor plans. Only the exterior lines need to be shown on the base map. Be sure to include a sketch of the full floor plans with your report. Directions of significant views should be shown on the sketch. SUBMIT THE FLOOR PLAN SKETCHES WITH YOUR MASTER PLAN.

6) Other materials as needed to complete the master plan (see attachment). If preliminary plat becomes too complex, you may use separate sheets to fulfill the above requirements. Be sure to include a VICINITY MAP.

7) Write up your master plan in the format provided. Alternate formats may be used WITH PRIOR APPROVAL FROM THE INSTRUCTOR. Your master plan must be word processed. Be sure to spell check the report. Points will be deducted for poor grammar and spelling.

8) See attached Master Plan and Subdivision Design Specifications for details.

Subdivision Design Specifications

1. The minimum lot size shall be 5,000 square feet. No lots may exceed 10,000 square feet unless approved by the instructor.

2. The minimum lot width shall be 60 ft.

3. The minimum lot depth shall be 70 ft.

4. The minimum street frontage shall be 40 ft. This applies to front-of-house street access.

5. The setbacks for houses shall be: front yard – 15 ft., rear yard – 15 ft., side yard – 5 ft.

6. Backyard ponding may be used for storm drainage control.

7. Streets shall be minimum 50 ft in width and built to standards allowing dedication to the City of Las Cruces (e.g. 60 ft minimum radius cul-de-sacs).

8. All lots will have community (city or other) water and septic systems.

9. No lots may have drives that go onto major arterial roads (e.g. any street or road with traffic speeds above 35 mph. No lot should have frontage on two streets except for corner lots and lots on major arterial roads. Driveways shall not be located within 60 feet of road intersections.

10. Centerlines of offset streets shall not be less than 125 feet apart.

11. All intersection shall have a minimum 25 ft. return radius.

12. No streets shall intersect at less than 75 degrees.

13. Reserve strips controlling street access are prohibited.

14. You may include parks, golf courses, or other amenities but be sure that you label these a proposed on the preliminary plat. These can also be used for drainage.

Master Plan Report Format

Discuss in the report how you propose to do each of the following:

1) Location and total size of project.

2) Access.

3) Number and size of proposed lots and buildings.

4) Drinking water supply.

5) Utilities provided by. Include electricity, gas, telephones, (cable TV?).

6) Solid waste disposal.

7) Sewage disposal.

8) Drainage plan proposal.

9) Street types. Include street widths and lengths.

10) Environmental considerations/constraints.

11) Site characteristics to be incorporated into design. (Views, buffers, ponds, etc.).

12) Any special considerations that affect the subdivision.

If one of these topics does not apply to your project, include a section that states why they do not apply.

e. location, dimensions, and purpose of existing and proposed easements

f. names and right-of-way widths of existing and proposed streets

g. locations, dimensions, and purpose of dedicated lands

h. vicinity map

i. archaeological, historical or cultural features (optional)

j. 100-year flood plain (optional)

k. names and addresses of owners

l. legal description reference(s) (e.g. deed book and page) of property being developed

Lab specifications

Number of lots

Lot size

Setbacks

Frontage
