2. Screening Of Mechanical Units: The following standards apply to the location and screening of mechanical equipment:
a. Screening Of Ground Mounted Mechanical Units: For all uses, except for single-family detached and bi-attached residential uses, all ground mounted mechanical units, including, but not limited to: air conditioning condensers, heat pumps, ventilation units, computer cooling equipment, etc., and any related utility structures and equipment, that are visible from any adjacent public thoroughfare shall be visibly screened from public view by the use of a screening wall built out of materials compatible and consistent with the architecture and materials of the principal building, landscape plantings of predominately evergreen materials to provide year round screening, or a combination of the above. The type of screening to be used shall be identified as part of the site plan submittal. (Ord. 2274, 2-5-2018)
b. Screening Of Roof Mounted Mechanical Units: All roof mounted mechanical units shall be screened from adjacent public thoroughfares by the use of an opaque screening material compatible with the architecture of the building or architecturally designed screening, such as a parapet wall. The screening of the roof mounted units shall be designed to blend with the building and roof materials. Additional screening may be required due to topographic differences in the adjoining properties.
c. Location Of Meters In Single-Family And Bi-Attached Developments: Single-family and bi-attached residential developments shall be prohibited from locating the mechanical units and meters in the front yard of the property unless adequate screening is provided to visibly screen these elements from the public view.
3. Screening Of Solar Energy Systems:
a. Ground mounted solar energy systems should be sited to visually mitigate undesirable features that are visible at grade from surrounding properties and public thoroughfares. The City is aware of the operating needs of these types of structures and acknowledges that it may be impossible to orient a system to hide its undesirable features such as the structural elements, rear face of the collector panels, mechanical equipment and accessories. Should any of these features be visible, the following options are acceptable methods of screening the view of these undesirable features:
(1) An enclosure or a freestanding screen wall or fence of an opaque design built out of materials consistent with the architecture and materials of the principal building. Landscape plantings may be implemented in combination with the screen enclosure, fence or wall to soften the appearance of the installation.
(2) Landscape plantings that are composed of evergreen materials to provide year round screening may be implemented in lieu of screen enclosure, fence or wall. Plant material shall be of sufficient height and size at the time of installation to fully screen the undesirable features of the system.
b. Building mounted systems do not require screening if they comply with the requirements as noted in section 9-14-14, "Solar Energy Systems", of this title. However the structural elements, equipment and accessories related to a system mounted on a flat roof that are visible from any adjacent public thoroughfare or adjacent property shall be selected to be a similar color to the roof surface or adjacent building materials to mitigate the visual impact of the system. Wall or ground mounted mechanical equipment related to any solar energy system as noted in subsection A2a of this section, will require screening.
4. Screening Of Trash Receptacles: For any development or properties where three (3) or more residential dwelling units are using a common trash receptacle and all nonresidential uses; trash receptacles and dumpsters shall be opaquely screened on all sides by the use of a permanent enclosure, with gates for disposal truck access. The enclosure shall be constructed of materials and colors compatible with the dominant architectural materials of buildings on site and shall be integral to a building on site whenever possible. The enclosure shall be constructed to visibly screen the receptacle from public view and views from the adjoining properties.

(1) Views of individual unit exterior access doors shall be screened from the public street or from adjacent nonindustrial or nonwarehouse retail zoned or developed property.
(2) The building(s) shall be surfaced with materials compatible with adjacent industrial or warehouse retail development. Facades visible from the public street shall be enhanced to add visual character and distinction from the interior of the development. Facades facing adjacent residential property shall be screened with a fence or evergreen landscaping and otherwise enhanced by incorporating front facade materials or enhanced materials used elsewhere in the development. Three hundred sixty degree (360°) architecture is not intended for ministorage, but those buildings visible from the street or adjacent residential developed or zoned property shall be expected to reflect material enhancements that may not be commonly considered in warehouse retail and industrial developments.
(3) Outdoor storage areas, as allowed in this title, should be consolidated into a single area and screened as required elsewhere in this title.
(4) Fences and walls used to provide screening shall be maintained in a neat, clean, safe, and structurally sound condition. RVs, boats, and recreational trailers may exceed the height of the fence or wall; all other materials shall not exceed the height of the wall or fence. Fences shall be placed no closer to the front lot line than the front yard established by the building or building setback line, whichever is greater.
(5) Wall signage for the development shall be calculated according to the Sign Code calculations located elsewhere in this title for the building facade in which the business office is located. No signage or advertising is allowed on screen walls or fencing.
(6) Vehicle circulation shall allow for two-way drive aisles and circulation with no dead ends.
b. Interior Unit Access: This building type is intended to allow for facilities where units are accessed by interior hallways. These structures shall emulate the exterior architecture and characteristics of buildings in the specific district in which the facility is located. The following development standards shall apply, in addition to development standards cited elsewhere in this title, including, but not limited to, landscaping, open space, buffers, screening, parking, setbacks, etc.:
(1) Office And Professional Commerce Park Districts: Interior unit access self-storage in the Office and Professional Commerce Park Districts is intended to be designed to be compatible with expected four-sided office design already exhibited in the City in these districts. The following performance standards also apply to the design of interior self-storage units:
(A) All storage units shall gain access from the interior of the building, no individual unit doors may face the street or be visible from off the property.
(B) One (1) entrance and one (1) exit overhead door shall be allowed. If the facility abuts residentially zoned property, the facility loading bays, docks, or doors shall not be visible from the residential property. Whenever possible, these features shall be located on facades which face non-residentially zoned or developed property. These features shall not be located on the facade facing the public street.
(C) Ground floor and upper floor facades shall be designed to be compatible with expected four-sided office design in the City's office districts. Examples of such architectural and design features include varied massing, proportion, facade modulation, exterior building materials and detailing, varied roof line, pedestrian scale, windows, repetition, etc. Views of storage units through windows shall be mitigated. The building shall look like an office building.
(D) The building shall be surfaced with high-quality, durable materials consistent with the surrounding office uses. Un-faced concrete block, painted masonry, tilt-up and pre-cast concrete panels and non-architectural metal siding are prohibited in the office districts. Prefabricated buildings are not allowed in the office districts.
(E) There shall be a pedestrian entrance facing the street. This entrance shall be considered the main or principal entrance, even if the tenants enter through loading docks, bays, doors or other side or rear entrances. This entrance shall present as a prominent feature that emulates an office lobby. This entrance shall not be used for the transfer of goods to the storage unit.
(F) To accommodate future potential redevelopment of the building, parking for re-use of the building for other permitted or permitted conditional uses in the applicable zoning district shall be demonstrated at the applicable ratio; however, only the parking required for the indoor self-storage shall be required to be constructed.
(G) Indoor self-storage facilities shall abide by all City codes and regulations such as, but not limited to, Building Code and Fire Code provisions.
(H) Tenant access shall be restricted to the hours of seven o'clock (7:00) A.M. to ten o'clock (10:00) P.M.
(2) Commercial Districts: Interior unit access self-storage in the commercial districts, to include the Valley Junction Historic Business District, is intended to be designed to be compatible with expected four-sided commercial design already exhibited in the City in these districts. Retail tenant spaces shall be included in the first floor design, which may include a retail space for the self-storage office. Tenant spaces shall extend the length of the facade which faces a main parking field and the public street where parking is available between the building and the public street. The intent is to emulate tenant and multitenant retail store fronts commonly associated with the commercial districts, to provide the retail activity for the districts, and to provide services to the community such is commonly available in these districts. In these instances, the self-storage use will be of secondary consideration to the retail atmosphere. The following performance standards also apply to the design of interior self-storage units:
(A) All storage units shall gain access from the interior of the building, no individual unit doors may face the street or be visible from off the property.
(B) One (1) entrance and one (1) exit overhead door shall be allowed. If the facility abuts residentially zoned property, the facility loading bays, docks, or doors shall not be visible from the residential property. Whenever possible, these features shall be located on facades which face non-residentially zoned or developed property or the public street. In no case will these features appear on the front facade or public facade where other commercial business takes place.
(C) Ground floor and upper floor facades shall be designed to be compatible with expected four-sided commercial design in the City's commercial districts. Examples of such architectural and design features include varied massing, proportion, facade modulation, exterior building materials and detailing, varied roof line, pedestrian scale, windows, repetition, etc. Views of storage units through windows shall be mitigated. The building shall look like a retail or multitenant commercial space.
(D) The building shall be surfaced with high-quality, durable materials consistent with the surrounding office uses. Un-faced concrete block, painted masonry, tilt-up and pre-cast concrete panels, non-architectural metal siding, and prefabricated buildings are prohibited in the commercial districts.
(E) To accommodate future potential redevelopment of the building, parking for re-use of the building for other permitted or permitted conditional uses in the applicable zoning district shall be demonstrated at the applicable ratio; however, only the parking required for the indoor self-storage shall be required to be constructed.
(F) Indoor self-storage facilities shall abide by all City codes and regulations such as, but not limited to, Building Code and Fire Code provisions.
(G) Self-storage access shall be restricted to the hours of seven o'clock (7:00) A.M. to ten o'clock (10:00) P.M.
c. Prohibited Uses: The only activity permitted in individual storage units shall be the storage of goods and property. Storage units shall not be used for:
(1) Residences, offices, workshops, studios, hobbies, events, or rehearsal areas;
(2) Manufacturing, fabrication, or processing of goods, services, or repair of vehicles, engines, appliances, or other electrical equipment or any other industrial activity;
(3) Retail sales of any kind including, but not limited to, garage sales, estate sales, auctions or to conduct any other commercial activity, except in the business office as permitted in the zone in which the facility is located; excludes auctions of units conducted by the property owner or manager due to nonpayment, default, or other storage business operation.
(4) The storage of flammable, perishable, or hazardous materials.
(5) The keeping of animals.

(2) The HVAC system for the tenant space shall be completely independent of any other tenant space to eliminate the transmission of sound or odors.
21. Recreational Facilities: Characteristics of elements or structures intended to support recreational activities can be determined by their purpose. This section intends to provide performance standards based on those activities or purposes as they relate to recreational uses.
a. Activity Area Lighting: Illumination of sport fields, courts, non-residential pools and driving ranges may occur as necessary. Light poles shall not be subject to setback or height regulations; however, lighting mounted on the poles shall be located at the minimum height necessary to achieve typical industry standards for illumination levels for the specific sport or use. Light fixture design shall be such to direct the light to its intended target or shields shall be added to minimize views of the lightbulbs themselves from adjoining properties. Unless otherwise defined as part of the City Council approval of a site plan development permit, activity area lighting that is within 1000' of residentially zoned or used properties shall be turned off within thirty (30) minutes of the conclusion of the activity or closure of the facility, whichever occurs first. All other lighting within a site, including parking lot lighting shall abide by regulations provided elsewhere within this title.
b. Activity Area Accessory Buildings: Support accessory buildings which contain uses or activities necessary for operation of the primary use or activity, such as but not limited to concessions, ticket sales, restrooms, equipment storage, and maintenance buildings shall be allowed in any number and at any square footage, subject to the following regulations. With the exception of structures for ticket sales, such buildings shall not be located in a front yard and shall be a minimum of twenty-five feet (25') from the property boundary, unless adjacent to single-family residential zoned or used property, in which case the minimum setback from property boundary shall be increase to fifty feet (50'). The height of building(s) shall comply with chapter 7 of this title.
c. Activity Area Structures: Structures to facilitate the use or components of the use, including supporting structures, such as but not limited to goal posts, scoreboards, bleachers, etc., and fencing or fence poles which provide a defined boundary, physical barrier, containment of an activity or component of the activity, or are otherwise necessary for safety of spectators or participants shall be allowed as necessary.
(1) For properties developed with single family and medium density residential dwelling units, said structures, may be allowed in a location and at a height which meets the applicable setback, height, and separation requirements for the applicable zoning district for that use. Fence materials shall comply with chapter 14 of this title.
(2) For non-residentially and high density residentially zoned properties, said structures may be allowed in a location and at a height necessary to achieve the intent and shall not be subject to setback or height regulations, nor shall be subject to separation from the primary structure requirements. Acceptable fence materials include all industry standard fence materials, including chain link, woven netting and wind or visual screen materials.
(3) Scoreboards: Scoreboards are accessory structures to the primary use of a stadium or recreational facility. The current technology available for scoreboards with video display capabilities creates concern for public safety due to the potential distraction to the motoring public viewing the scoreboard from adjacent roadways and the potential intrusion of light and sound into adjacent properties. Every effort should be made in the design and placement of the scoreboard to limit and screen the view of any video display component of the scoreboard from the general public. If the scoreboard cannot be screened to adequately limit its view to patrons of the stadium or recreational facility, and a continuously unobstructed view to the general public of more than five (5) seconds exists, the following performance standards shall apply:
(A) Full use of all capabilities of the scoreboard shall be allowed only when an event is in progress within the stadium or recreational facility.
(B) Full use of all capabilities of the scoreboard during the day of an event shall be limited to pregame warmups, game duration and postgame postings.

The structure shall be located to comply with the vision clearance requirements of chapter 14 of this title. Utility structures can exist on a lot without an associated principal building. A lot containing only a utility structure does not need to meet the minimum lot size requirements for the zoning district.
Public utility structures exceeding one thousand (1,000) square feet need to meet the principal structure setbacks for the specific zoning district where they are located.
25. Tasting Rooms In Conjunction With A Distillery: In those districts where a tasting room is allowed, the tasting room shall only be allowed by approval of a permitted conditional use permit to operate in conjunction with a distillery. The distillery must have a native distilled spirits liquor control license issued through the State of Iowa and a Class LC liquor license issued by the City. For tasting rooms exceeding fifty percent (50%) of the gross square footage of the distillery, or serving cocktails, spirits or liquor produced elsewhere, those uses will be considered a drinking place/bar for purposes of this subsection A25 and regulation.
Parking space requirements for a distillery with a tasting room will be calculated at the parking rate for SIC 5813, drinking places for that portion of the distillery identified as the liquor consumption area. This parking calculation shall be in addition to the parking requirement for SIC 2085, distillery for that portion of the distillery identified for production purposes.
26. Factory Built Structures: All factory built structures not designated as a manufactured or mobile home or a trailer for temporary business or storage use must meet all bulk regulations and design standards of their respective zoning district.

G. The Following Standards Shall Apply To Uses Within The Professional Commerce Park District:
1. Intent Of The District: The principle of spacious separation and adaptation of the manmade elements to be harmonious with the natural environment shall dominate the central design theme of the site and structural planning in this district. To accomplish this objective, the standards listed below shall be considered as minimum acceptable standards. While this district is predominately occupied by spacious office uses, certain uses not considered professional- commerce and certain inherent physical characteristics shall be considered compatible or incompatible with the intent of this district as follows:
a. Retail commercial uses not specifically permitted in this district, with independent access to the building and/or signage that is visible from the exterior of the building, shall be prohibited. Any enterprise or service which is specifically intended to augment, facilitate, be subsidiary and be accessory to the planned principal uses shall be permitted, providing such use shall be physically accomplished in an aesthetically compatible manner wholly within the confines of the building and shall comply with all restrictions or performance standards applicable to the principal uses.
b. Any enterprise which cannot wholly enclose its functions within the principal structures or otherwise effectively conceal its functions from public observation, shall be prohibited. Drive-through windows and drive-up facilities shall be prohibited in this district except as otherwise identified in this title. Any drive-through facility shall be screened from the public thoroughfare through the use of: 1) berming and landscaping, or 2) fencing and landscaping, or 3) architectural screening.
(1) Berming: Designed by a registered landscape architect, architect or engineer; with earth berming and landscape plantings, the plantings shall be predominately of evergreen type trees and shrubs as to assure year round effectiveness. The earth berming shall be a minimum height of three feet (3') above the top of curb of the adjoining parking lot, if applicable, or public thoroughfare, whichever is higher, and shall be designed to not negatively affect the drainage of the surrounding area and to be aesthetically pleasing to the general public. Berms may be required to be higher if the minimum height is identified during the development review process as being inadequate to provide effective screening and buffering.
(2) Landscape Plantings: The equivalent of one overstory tree and three (3) shrubs per thirty five (35) linear feet of the area adjacent to the public thoroughfare. Deciduous trees shall be a minimum two (2) to two and one-half inch (21/2") caliper, evergreen trees shall be a minimum six feet (6') in height and will be equal to one overstory tree. Shrubs shall be a minimum size of eighteen inches (18") to twenty four inches (24"). Whenever practical, existing trees and shrubs should be preserved and incorporated into the overall design and can be included to meet the total number of required trees and shrubs, if it is determined during the development review process that the existing trees will provide the necessary screening and buffering.
Substitution of plant materials will be allowed at the following rate:
Two (2) ornamental trees or five (5) shrubs may be substituted for one overstory tree.
In no case shall the substitution of overstory trees be in excess of fifty percent (50%) of the required number, except in extenuating circumstances, such as under overhead power lines.
In any case, the design shall simulate natural tree stands with groupings and masses rather than linear or symmetric lines, unless the overall landscape design is of a more formal nature and deemed appropriate by staff during the development review process.
(3) Fencing And Architectural Screening: Architectural design and use of materials for the construction within the property shall be accomplished in a manner compatible with PCP professional commerce park zone district building standards. The architectural design of the fencing and screening shall be acceptable to the city, by being reviewed by city staff, recommendation made by the planning and zoning commission and approved by the city council. The design and style of such an element shall be in context with the surrounding environment and shall be constructed such that the drive-through is visually screened from the public view and adjoining properties. Drive-throughs located away from the public view (rear yard or side yard) are preferred.
H. The Following Standards Shall Apply To All Uses Within The Business Park District Unless Noted Otherwise In This Title:
1. Outside Storage: Any enterprise which cannot wholly enclose its functions within the principal structures shall be prohibited.
2. Architecture: While it is not the purpose of this chapter to dictate or specify building materials and structural standards, the importance of material strength and permanency and their relationship to the central aesthetic character of the district shall be recognized. The use of high quality, durable materials will result in appreciation of improvements over time.
a. The architectural design of any building shall be acceptable to the city, and all buildings within a property shall have all sides of any building built on the property consistent in design and use of materials. No wood, masonite, visible asphaltic exterior wall or roof material, aluminum siding, nonarchitectural sheet metal, concrete block, or other similar materials shall constitute a portion of any building except as a trim material, unless the city council, after having received a recommendation from the planning and zoning commission, shall determine said material, when used as a primary element, enhances the physical appearance, or provides continuity desired to unite all structures within the property together into one project concept.
b. Preferred building materials include, but are not limited to, brick, stone veneers, granite, architectural metals, cast in place concrete panels, decorative concrete block and tinted glass.

K. Regulation Of Specific Activities, Jordan Creek Town Center Overlay District:
1. Purpose: The purpose of this subsection M is to provide for the reasonable regulation of specific activities within the Jordan Creek Town Center Overlay District to ensure that such activities are harmonious with the pedestrian oriented village atmosphere of the district and that the operation of such activities is compatible with the surrounding land uses.
2. Findings: The City Council makes the following findings:
a. The Town Center Overlay District is an overlay zoning district that seeks to incorporate residential, retail, office and recreational activities in a specific area of the City. The overall objective of the district is to create a village atmosphere that provides a safe, convenient, energetic and attractive area in which to live, work, shop and play.
b. The Town Center Overlay District seeks to achieve a pedestrian friendly environment while offering a varied choice of residential, retail, office and recreational opportunities.
c. The Town Center Overlay District seeks to balance the presence of office and retail establishments with the goal of creating a traditional residential community. Attaining a balance between the integration of office and retail establishments with a residential community to achieve a traditional work, live and play environment requires reducing the dependence upon and dominance of the automobile and recognizing the appropriate relationship between each permitted land use.
d. Certain permitted uses within the Town Center Overlay District provide the appropriate balance and serve to complement other permitted uses within the district. However, the secondary effects of such uses may be detrimental to the surrounding area.
e. Commercial and retail establishments in excess of one hundred thousand (100,000) square feet generate significantly more traffic, noise and light than other uses permitted within the district.
f. Larger retail establishments tend to attract a concentration of customers and traffic patterns that are not compatible with the sleep and domestic patterns of traditional neighborhoods; smaller retail establishments do not attract similar concentrations of customers or such concentrations of traffic patterns.
g. Large retail establishments, while appropriate at certain hours, are inappropriate at other hours due to the generation of traffic, noise and light which detrimentally affect both the residential uses of the district and the surrounding residential areas.
h. Additionally, automotive repair facilities, while appropriate in a mixed use environment at certain hours, also generate excessive noise due to the nature of the facility, and their operation is therefore inappropriate in a mixed use environment after certain hours.
i. Commercial, retail and office uses also require the delivery of merchandise and supplies by commercial motor vehicle which are necessary for the operation of the commercial, retail or office use. Such deliveries often generate noise that may cause undue disruption to the surrounding area.
j. Residential uses are more sensitive to the noise and disruption caused by the delivery of the merchandise and supplies, making it necessary to balance the needs of the commercial, retail and office uses with the needs of the surrounding residential uses.
k. In seeking to provide the desired traditional relationship between all permitted uses within the district while addressing the detrimental effects large commercial and/or retail establishments may have on existing land uses both within and surrounding the district, the imposition of reasonable conditions is necessary.
Therefore, based upon the findings set forth above, it is the determination of the City Council of the City of West Des Moines that the following conditions are the most appropriate and least restrictive and are reasonable and necessary to address the detrimental effects resulting from certain uses within the Town Center Overlay District.
