A. Application: Each planned unit development proposal shall submit a tentative development plan which provides a development suitability analysis and land use concept plan for the project which establishes the constraints and opportunities for development of a site, and sets forth in the form of written text, diagrams, and/or maps one or more development alternatives and the planning objectives to guide and control the future development of the site.

h. The location, size, and variety of trees having a six inch (6") or greater caliper at five feet (5') above ground or, where the site is heavily vegetated, an aerial photograph at the same scale as the site analysis and a drawing showing the location, size, and variety of only the vegetation that will be affected by the proposed development;
i. Identification information including the name, address, and phone number of the owner, developer, and project designer;
j. A north arrow and the scale.
4. A geotechnical investigation report which shows the following: slope stability studies, on-site site grading, cutting and filling; structural foundation requirements; surface and subsurface drainage recommendations; erosion vulnerability; building or grading limitations, including top of slope offsets and areas restricted for site grading; recommendations for construction of streets, utilities, and structures of the site; and identification of any portions of the site requiring further evaluation by a geotechnical or structural engineer. Unless the Director determines that a geotechnical investigation is warranted due to site-specific characteristics, projects meeting all of the following criteria are exempt from this requirement:
a. Construction value of the project is one hundred fifty thousand dollars ($150,000.00) or less;
b. The project will not involve the import, export, and/or on- site movement of more than one hundred (100) cubic yards of earth;
c. There is no evidence of any previous fill on the site to a depth exceeding one foot (1');
d. The project does not include proposed cuts or fills on the site to a depth exceeding one foot (1'); and
e. No portion of the site has a slope in excess of ten percent (10%).
5. A site plan, drawn at the same scale as the site analysis, which, on one or more sheets, shows the following:
a. The applicant's entire property and the surrounding property to a distance sufficient to determine the relationship between the applicant's property and proposed development and adjacent property and development;
b. Boundary lines and dimensions for the perimeter of the property and approximate dimensions for all proposed lot lines;
c. Section lines, corners, and monuments;
d. Identification information, including the name, address, and phone number of the owner, developer, and project designer;
e. The scale and north arrow;
f. The location, dimensions and names of all:
(1) Existing and platted streets and other public ways and easements on adjacent property and on the site,
(2) Proposed streets or other public ways, easements on the site and on adjoining property;
g. The location, dimensions, and setback distances of all:
(1) Existing structures, improvements, utility, and drainage facilities on adjoining properties,
(2) Existing structures, improvements, utility and drainage facilities to remain on the site,
(3) Proposed structures and improvements and conceptual plans for utilities, fire suppression and drainage facilities on the site;
h. The location and dimensions of:
(1) The entrances and exits to the site,
(2) The parking and circulation areas,
(3) Pedestrian and bicycle circulation patterns,
(4) On-site outdoor recreation spaces and common areas,
(5) Above-ground utilities;
i. The location of areas to be landscaped;
j. The location and type of street lighting;
k. The orientation of structures, except single-family detached structures and duplexes;
l. The location of group mail boxes.
6. Preliminary architectural drawings including proposed building elevations, sections, and floor plans, except for detached single-family and duplex dwelling units;
7. A preliminary grading and drainage plan including written statements and descriptions as necessary, at the same scale as the site analysis, addressing the following:
a. The location and extent to which grading will take place indicating general contour lines, slope ratios, and slope stabilization proposals;
b. A statement from a registered engineer supported by factual data that all drainage, both upstream and on the site, can be accommodated, and the amount and rate of run-off leaving the site is minimized;
c. A plan, where on-site detention is not feasible, which identifies and mitigates any off-site adverse effects resulting from increased runoff; the plan shall be prepared by a registered engineer;
d. Identification information, including the name and address of the owner, developer, project designer, and the project engineer.
8. A conceptual landscape plan, drawn at the same scale as the site plan, which on one or more sheets shows:
a. The conceptual location of the underground irrigation system or hose bibs (a general description of maintenance of landscaped areas may be submitted where no irrigation system is proposed);
b. The location and height of fences and other buffering or screening materials;

d. The location, size, and variety of the trees to be removed.
9. A map showing how proposed street, sidewalks, bike routes and bike ways and pedestrian connections within the proposed planned unit development may be extended onto adjoining undeveloped properties so as not to preclude their efficient development.
10. A connectivity analysis prepared by a qualified professional describing the existing and future vehicular, bicycle and pedestrian connections between the proposed planned unit development and existing and planned land uses on adjacent properties.
11. The applicant shall submit either:
a. A determination by USA that site assessment is not necessary, or
b. A USA Service Provider Letter.
12. An applicant for a project or phase of a multi-phase project that is forecast to generate one hundred (100) or more average daily auto trips, shall submit as a part of the PUD application a traffic impact report. The report shall analyze the impact of the project or phase of a project on the County and State road and street systems within one mile of the borders of the project or phase of a project, or to such greater distance as necessary until the traffic analysis shows that the impact of the project or phase of a project has dissipated to where it no longer results in an impact of ten percent (10%) or more over current conditions. Such report shall be prepared and certified by a registered traffic engineer licensed in the State of Nevada. The required report shall comply with the standards listed in the Lyon County Design Criteria and Improvement Standards for Traffic Analysis contained in appendix B on file in the County.
13. The proposed covenants, conditions and restrictions to be recorded if the PUD is approved. The covenants, conditions and restrictions shall incorporate appropriate provisions for the establishment and maintenance of long-term PUD site development standards, including enforcement mechanisms designed to assure coherent, coordinated development, maintenance and use activity with the PUD site.
14. Letters of Intent to Serve from each utility providing service to the planned unit development.
15. Tentative map or maps for all land included in the PUD. Tentative subdivision maps, if processed concurrently with the tentative PUD approval application, shall be prepared in accordance with the standards for tentative maps contained in the Lyon County Design Criteria and Improvement Standards, appendix B on file in the County.
B. All reports, plans, and documents submitted as elements of the preliminary plan shall be prepared in accordance with the requirements of this section and appendix B on file in the County. Where a conflict exists, the stricter requirement shall be followed. (Ord. 603, 11-1-2018)
