blade must be at least twenty feet (20’).
4.
Small wind energy systems shall not be illuminated or bear any
signs or advertising.
5.
Small wind energy systems must have automatic braking, governing,
or feathering system to prevent uncontrolled rotation, over-speeding,
and excessive pressure on the support structure, rotor blades, and
turbine components.
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
|
|
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).
