6. 
All wiring serving small wind energy systems must be underground.
7. 
Small wind energy systems must not cause any interference with normal radio and television reception in the surrounding area, with any public safety agency or organization (including but not limited to police, fire, and ambulance) radio transmissions, or with any microwave communications link. The owner shall bear the cost to conduct a study to determine interference and must immediately eliminate any such interference should any occur by adjusting, modifying, or ceasing the use of the system or part(s) causing the interference.
8. 
The owner shall paint or surface the small wind energy system with a color and texture that reduces the visibility of the facility, including the rotors such as a flat light haze gray paint.
9. 
If the support structure is unpainted it must be of a single color throughout its height.
10. 
The owner must maintain the finish, painted or unpainted, so that no discoloration occurs.
11. 
The diameter of the area swept by the rotors may not exceed twelve feet (12’).
C. 
Freestanding systems - additional standards. Small wind energy systems may be mounted on a tower detached from other structures on the lot.
1. 
Setback. The minimum setback from any property line, overhead utility line, or public or private Right-of-Way shall be a distance equal to the vertical distance from the ground to the tip of a wind generator blade when the tip is at its highest point.
2. 
Height. Freestanding systems measured from the top blade shall not exceed the maximum height of the district in which the system is located.
D. 
Roof-mounted systems - additional standards. Small wind energy systems may be mounted on the roof of a structure as an appurtenance.
1. 
Height.
(i) 
Roof-mounted systems may not exceed the maximum height allowed for an appurtenance in the same district or fifteen feet (15’) above the maximum height for the district.
(ii) 
A roof-mounted system that exceeds the maximum height for the district must be set back an additional foot for every one foot (1’) in height above the maximum height for the district.
E. 
Engineering report.
1. 
Before any wind energy system is installed, the property owner must submit a report prepared by a licensed professional engineer attesting to the fact that the support or structure to which the system will be mounted is or will be sufficiently strong to support the system and to withstand the wind, vibratory, and other loads to which it would be subjected as a result of mounting the system on it.
2. 
This report is subject to approval by the Building Official prior to the mounting of the system.
(Ordinance 475 adopted 6/28/22)
A. 
Purpose. Rainwater harvesting allows for the reuse of rainwater for non-potable irrigation purposes. This practice is intended to reduce stormwater runoff and water consumption.
B. 
General regulations.
Figure 6.7.4-1: Rainwater Storage Tanks
UDC_Page_355_Image_0001.tif
1. 
Storage tanks are required to have an overflow spout (see Figure 6.7.4-1).
2. 
Storage tanks must be clearly labeled "RAINWATER - DO NOT DRINK".
3. 
Storage tanks must be maintained in a condition that does not create a public nuisance or public health hazard.
4. 
If the storage tank is connected to a potable water supply through an irrigation system, it must utilize backflow prevention measures.
5. 
Facilities must meet the City’s technical specifications.
C. 
Residential purposes. Storage tanks larger than fifty-five (55) gallons shall not be located in the area between the building front of the building and the front property line. On corner lots storage tanks larger than fifty-five (55) gallons shall also not be located between the side of the building facing the street and the corresponding side property line. In the R-4 and R-5 districts the Director may waive these requirements if the tanks are designed in a manner that is complementary to the building design and building materials.
D. 
Nonresidential purposes. Unless located in the side or rear yard, storage tanks larger than one thousand five hundred (1,500) gallons must be designed in a manner that is complementary to the building design and materials as determined by the Planning Director (see Section 3.4.9 Pools, Patios, Accessory Buildings and Structures).

Table 6.7-1, Low Impact Design Element Options includes a list of design element options for implementing Low Impact Design in residential and nonresidential developments. This table is referenced throughout the UDC. See also 7.37.3.2.P [sic]
Table 6.7-1: Low Impact Design Element Options

Alternatives
Cool Roof
All roof surfaces are a "white" or "green" design
White roof: Roof painted with solar reflective white coating that reflects at least 80% of sunlight to maintain the home at a cooler temperature
Green roof: Layer of vegetation on the entire rooftop to reduce heating and cooling costs, improve water quality, and reduce runoff; structural analysis of roof support required
Connectivity

Conservation
At least 25% of the site is conserved in a natural state, excluding nature paths
Cover
Use at least 20% less than the maximum impervious cover allowed by district
Drainage
Disperse drainage and minimize the velocity of concentrated water flows through the use of check dams or landscaping and direct sheet flow to areas of vegetation
Erosion
Utilize a minimum of two permanent erosion control techniques (e.g., filter strip, inlet protection) along all streets and sidewalks to minimize sedimentation in nearby streams and water bodies
Garden
Provide a community garden maintained by an HOA or similar entity
Infill
Entire site is located in a redevelopment area with infrastructure available or nearby; no greenfield development
Permeable
Use pervious or semi-pervious surfaces that allow water to infiltrate in all on-site Hardscape pedestrian areas
Rainwater
All structures are constructed with rainwater harvesting facilities at downspout disconnects for reuse with landscaping irrigation or toilets; harvesting facilities must be able to accommodate at least 20% of the volume generated by a 1" storm based on the roof area
Recycled
Use only recycled materials including asphalt for roadways, as approved by the City Engineer
Runoff

Solar
At least 1.5 photovoltaic kW per residential unit (average for entire development) or 2.5 kW per 1,000 sq. ft. of nonresidential rooftop
Miscellaneous
Other site development controls as approved by the Planning Director
