These standards apply to more than one land use district, so they are combined in this chapter. These standards are to be considered in conjunction with those standards and design guidelines located in the specific land use district chapters and in the County’s design criteria and improvement standards manual. 
A.  Access. Every structure or use shall have frontage upon a public street or permanent means of access to a public street by way of a public or private easement, or recorded reciprocal access agreement. 
B.  Antennas, vertical and satellite dish. All antennas, including portable units and satellite dishes that do not meet the definition of a telecommunications site or telecommunications facility pursuant to sections 20.660.130.H and 20.660.130.I, are subject to the following standards: 
1.  Antennas shall not be located within the front yard or street side-yard areas. 
2.  The operation of the antennas shall not cause interference with any electrical equipment in the surrounding neighborhoods, including but not limited to television, radios, telephones, and computers, unless exempted by Federal regulation. 
3.  Ground-mounted satellite dish installations for residential purposes must be 105 inches or less in diameter, 12 feet or less in height, and located in the rear yard. Ground-mounted satellite dish installations that are six feet or less in height may be located in the side yard area if screened by a solid six-foot fence. 
4.  Roof mounted satellite dishes must be screened according to the provisions of this title and the design manual. 
5.  A building-mounted satellite dish may be located anywhere on the structure provided that the dish is 24 inches or less in diameter. 
6.  Single-pole or tower roof, building or ground-mounted television or amateur radio antennas, including the boom or any active element of the antenna array, are limited to 35 feet in height.
C.  Design considerations. The following standards apply to uses which are subject to design review and are in addition to the specific design guidelines contained in the individual land use districts: 
1.  The proposed development shall be of a quality and character whish is consistent with the community design goals and policies including but not limited to scale, height, bulk, materials, cohesiveness, colors, roof pitch, roof eaves and the preservation of privacy. 
2.  The design shall improve community appearance by avoiding excessive variety and monotonous repetition.
3.  Proposed signage and landscaping shall be an integral architectural feature which does not overwhelm or dominate the structure or property. 
4.  Lighting shall be stationary and deflected away from all adjacent properties and public streets and rights-of-way. 
5.  Mechanical equipment, storage, trash areas, and utilities shall be architecturally screened from public view. 
6.  With the intent of protecting sensitive land uses, the proposed design shall promote a harmonious and compatible transition in terms of scale and character between areas of different land uses. 
7.  Parking structures shall be architecturally compatible with the primary and surrounding structures. 
8.  Piecemeal mansard roofs (used on a portion of the structure perimeter only) are prohibited. Mansard roofs, if utilized on commercial structures, shall wrap around the entire structure perimeter. 
D.  Dust and dirt. Grading activity greater than five acres shall comply with the appropriate NRS provisions regarding air quality permits and grading. Grading activities conducted on property less than five acres in size shall be conducted so as not to create any measurable amount of dust or dirt emission beyond any boundary line of the parcel. To ensure a dust free environment, appropriate grading procedures shall include, but are not limited to, the following: 
1.  Scheduling all grading activities to ensure that repeated grading will not be required, and that implementation of the desired land use (e.g. planting, paving or construction) will occur as soon as possible after grading; 
2.  Disturbing as little native vegetation as possible; 
3.  Watering graded areas as often as necessary to prevent blowing dust or dirt, hydro-seeding with temporary irrigation, adding a dust palliative, or building wind fences; 
4.  Re-vegetating graded areas as soon as possible; 
5.  Constructing appropriate walls or fences to contain the dust and dirt within the parcel subject to the approval of the director. 
E.  Exterior building walls. The following standards shall apply to those uses subject to design review: 
1.  Since walls will always be a main architectural and visual feature in any major development, restraint must be exercised in the number of permissible finish materials. The harmony of materials and particularly color treatment is essential to achieve unity in the project. 
2.  The following designs are deemed unacceptable in any development (with the exception of agricultural buildings located in the A-19 or FR districts, or buildings within the Airport zoning district) and therefore shall be prohibited: 
a.  Non-anodized and unpainted aluminum finished window frames; 
b.  Metal grills and facades. However, grills and facades of unique design and in keeping with the general decor of the development and neighborhood may be permitted subject to prior approval by the director; 
c.  Aluminum or other metal panels are not permitted on the street elevation, unless it can be demonstrated that they are consistent with a structure’s overall design character; 
d.  Exterior roof access ladders must be screened from view.

i.  Divisions of land into large parcels.
3.  Required approvals for projects. No tentative subdivision map, tentative parcel map, special use permit, building permit, design review, grading permit, construction permit or other discretionary approval shall be granted for a project unless the person or entity authorized to grant approval affirmatively finds, in addition to the required findings for the underlying discretionary approval, that the project complies with the provisions of this section.
4.  Processing procedures and submittal requirements for projects. 
a.  For every non-exempt building or construction permit application which requires a grading permit under the Uniform Building Code as adopted by Douglas County and for every non-exempt tentative subdivision map, tentative parcel map, design review, special use permit or other discretionary approval of a project which proposes to disturb areas as defined in section 20.690.030.K.1. (Applicability), the applicant must submit the items and information listed in paragraphs b and c of this section to the community development department. This list is not exclusive and additional information or studies may be required for review of the project pursuant to the requirements of the underlying zoning district, process or procedure for review being applied for, and laws pursuant to the Nevada Revised Statutes, the Uniform Building Code as adopted by the County or this code. 
b.  An applicant must submit the following to the community development department unless specifically waived by the director:
i.  Slope Analysis (see figure 20.690.030.K.4.b.i, Appendix C).

b.  Total land area within each category must be indicated on a table to be provided on the map face.
ii.  Grading plan. 
a.  A grading plan, prepared by a Nevada registered professional engineer, must include the height and width of all manufactured slopes, proposed drainage patterns, methods of storm water detention or retention, and identification of areas to remain in a natural state must be clearly shown. Off-site contours for adjacent, unimproved areas within 100 feet of the project’s boundaries must be provided. When adjacent property is improved, pad elevations, access streets, street grades, wall sections, and any approved or existing improvements immediately adjacent to the subject property, must also be shown. 
b.  One copy of the grading plan showing cut and fill areas, including preliminary building pad locations, driveway location and access points.
iii.  Cross sections, preliminary cut and fill.
a.  No less than two cross sections which completely traverse those portions of the property proposed to be graded at appropriately spaced intervals in locations where topographic variation is the greatest. The exhibits must be prepared by a registered Nevada professional engineer. The cross sections must clearly depict the vertical variation between natural and finished grade.

iv.  Engineering for all roads providing access to the proposed sites.
5.  Grading control. 
a.  The department may issue a permit when the plans conform to the provisions of this section. The department must consider the purpose, intent and the criteria established in this section, together with applicable standards and must approve the design if all applicable provisions are met. 
b.  The applicant or developer must be responsible for the maintenance of all slope planting and irrigation systems until the properties are occupied or until a homeowner’s association accepts the responsibility to maintain the landscaping in common areas, or other maintenance district formation is established. These areas must be maintained in perpetuity by the property owner, homeowners association or maintenance district. 
c.  Any person who grades in those areas subject to the provisions of this title without prior county approval of plans for such work, subject to this section, shall be in violation of this ordinance. Abatement of the violation may include the property owner undertaking the restoration (under county supervision and monitoring), or that failing, county-contracted restoration of the disrupted area. The property owner may be charged the cost of the restoration together with the direct costs of supervision and monitoring of the restoration. If the property owner fails to reimburse the county the costs incurred, a lien against the property for payment may be instituted and collected. 
d.  The provisions of this section are in addition to other county code titles and regulations applicable to grading activities within the county including the Uniform Building Code as adopted by the County. 
e.  The department may apply conditions when the proposed development does not comply with applicable standards. Conditions may be attached to the approval of grading plans so as to achieve the following objectives: 
i.  The health and safety of the public; 
ii.  The preservation of stream courses and encouraging re-vegetation with drought-tolerant native species; 
iii.  The avoidance of excessive building padding or terracing and cut and fill slopes to reduce the scarring effects of grading (see figure 20.690.030.K.5.e.iii & iv, Appendix C); 
iv.  The use of contour grading techniques to ensure optimum treatment of natural hillside and drainage features and soften the impact of grading on hillsides, including rolled, sloping, or split pads, rounded cut and fill slopes (see figure 20.690.030.K.5.e.iii & iv, Appendix C); 
v.  Erosion prevention during construction and long term avoidance through proposed design and maintenance measures. 
vi.  Compliance with the provisions of this section.
The plans and drawings may be disapproved but the county must specify the standards that are not met. 
6.  Grading standards. No development in a hillside area shall be approved unless the development, or the development as modified with conditions, complies with the following standards: 
a.  For the construction of utilities, all areas of cut must be restored to natural grade and re-vegetated to conform to the character of the surrounding natural terrain. In order to reduce grading disturbance during utility installation, all utilities must be incorporated in common trenches and access roads, where practical. 
b.  Mass grading of hilltops, ridges, and ravines is prohibited. 
c.  All manufactured or man-modified slopes must be stabilized, made to conform to the surrounding natural terrain, and must be re-vegetated to conform to the natural character of the surrounding area.
d.  The maximum height for manufactured slopes is 30 feet (see figure 20.690.030.K.6.d, Appendix C).
e.  Manufactured fill slopes adjacent to primary and secondary arterial must be no steeper than 4:1 within landscaped areas and public right-of-ways and must not exceed ten feet in height unless the slope is lower in elevation than the roadway (see figure 20.690.030.K.6.e, Appendix C).
f.  Grading on the perimeter of the site must not be designed with perimeter downslope to property lines unless a homeowners association, slope maintenance district, or similar entity is established for maintenance of the downslope. Exemptions to this requirement may be made for downslope to property lines with a ratio of 5:1 or less. For interior slopes between lots, manufactured building pads must be designed with up-slopes to property lines. 
g.  Plot plans must indicate a minimum 20 foot setback from the rear dwelling wall to the toe or top of a manufactured slope or retaining wall and a minimum 10-foot setback from the side dwelling wall. The only exception to this standard would be in the case of a terraced rear yard where multiple levels of functional yard space are provided (see figure 20.690.030.K.6.g, Appendix C).
h.  All manufactured slopes must be rounded at the top and at the toe of slope. The radius of the rounded slope shall be calculated by dividing the overall height of the slope by three (H/3) (see figure 20.690.030. K.6.h, Appendix C). 
i.  Manufactured slopes in excess of 200 feet in length and greater than eight feet in height must be designed with horizontal curvature that simulates the horizontal surface variations of natural contours.
j.  Cross lot drainage may be utilized to reduce grading if an overall design and method of maintenance is established to the satisfaction of the director. Terrace drains must be subject to maintenance by private homeowners associations or individual property owners (see figure 20.690.030.K.6.j, Appendix C). 
k.  Any continuous manufactured slope within a parcel map, serial parcel map or subdivision with a slope ratio of 3:1 or steeper, a vertical height of 20 feet or greater, and which abuts five or more lots (see figure 20.690.030.K.6.k, Appendix C), shall require the creation of a property owners association or other maintenance entity with provision for the collection of fees or assessments designated specifically to pay costs associated with the maintenance of these slopes, as well as to create easements or homeowners association lots for maintenance of all slopes falling under this category. The slope maintenance entity, rather than individual property owners, will be responsible for maintenance of the slopes. The tentative parcel or subdivision map must be designed to provide access to the slopes by easements which do not access the slopes through individual lots. No fences shall be permitted between lots within the slope easement areas. Slope easement areas may be included as lot area for purposes of calculating lot size. Permanent structures must not be permitted within common slope easement areas.
L.  Hours of construction. The hours of operation for all building construction activities not within a dedicated road right-of-way are as follows: 7:00 a.m. to 7:00 p.m. Monday through Friday; 8:00 a.m. to 7:00 p.m. Saturday and Sunday.
