(a) ALLOWED BUILDING TYPES. Building types regulated in this division are allowed in the Moline Centre districts per Table 3903-1. All buildings and site development must comply with one of the building types in this section, unless otherwise expressly stated in these zoning regulations.
(1) EXISTING BUILDINGS AND LOTS.
b. Expansions and Renovations. For expansions and renovations to buildings existing on the effective date of this code, the zoning administrator must approve the selection of a building type allowed in the district within which the building is located. Refer to Table 3903-1. A design adjustment (see Sec. 35-3909(e)) may be approved for use of a building type allowed in another district and specifically defined within this division.
(2) ACCESSORY STRUCTURE REGULATIONS. Except as defined in the building type regulations, accessory structures are subject to the regulations in Sec. 35-3905.
(3) EXEMPTIONS. Where the principal use on the lot is primarily outdoors, the following applies:
b. Principal Buildings. Any principal use buildings on the site must comply with the building regulations that apply to a building type allowed in the subject district, except the regulation for minimum primary streetwall.
c. Rear Yards without a Principal Building. The rear yard location for parking and accessory structures to the principal use (e.g. a restroom structure is accessory to a principal outdoor recreation use) must be determined by the zoning administrator.
d. Side and Rear Setbacks Apply. Side and rear setback regulations of the building type must be met for all structures.
e. Height. The height of any structure is limited to no more than 2 stories, with story heights defined by the building type. Additional height may be approved through a design adjustment process (see Sec. 35-3909(e)).
f. Utility Structures. Larger utility structures may require additional regulation per the zoning administrator, including front setbacks.

(d) PROCEDURES & APPROVALS. See Sec. 35-3909 for development approval procedures, including Sec. 35-3909(d) for administrative adjustments allowed to the building type regulations and Sec. 35-3909(e) for the design adjustment process. Allowed design adjustments are expressly defined throughout this code.
(e) OTHER APPLICABLE REGULATIONS. The following regulations apply to all sites zoned as Moline Centre districts. Any other applicable regulations established by the City may also apply.
(1) HISTORIC PRESERVATION. See the City's map for the limits of the Downtown Commercial Historic District and Article IV of Chapter 25 of the City's code of ordinances for review and approval procedures of any project within the historic district or projects designated as historic landmarks.
(2) PUBLIC ART CORRIDORS. Buildings located along Cultural Corridors must meet the public art requirements for private development in Division 3, Article IV of Chapter 35. See the City's Public Art Plan. Cultural corridors abutting the Moline Centre districts include:
a. 19th Street from 7th Avenue to the riverfront.
b. River Drive from 12th Street to 34th Street.
c. 5th Avenue from 10th Street to 11th Street.
d. 5th Avenue Place from 11th Street to 12th Street.
e. 6th Avenue from 11th Street to 23rd Street.
f. 12th Street from 6th Avenue to River Drive.
(f) APPLICABLE TO ALL BUILDING TYPES. The regulations of this subsection apply to all building types in the Moline Centre districts, unless otherwise stated.
(1) PERMANENT BUILDINGS. All buildings must be of permanent construction without a chassis, hitch, or wheels, or other features that would make the structure mobile, unless otherwise expressly stated in this code, and except temporary buildings as allowed per Sec. 35-3418.
(2) STREET FRONTAGE. All lots must front a public street.
(4) PRIMARY FRONTAGES. Primary frontages generally establish the fronts of lots and buildings, and determine where to locate the principal entrance to the building. Per the building type regulations, primary frontages require the highest level of facade treatment and restrict the location of parking, driveways, and garage entrances.
a. Primary Street Designation. Primary frontage treatments are required along primary streets designated as follows:
1. Primary Streets. Primary streets in Moline Centre include River Drive, 5th Avenue, 6th Avenue, 7th Avenue, 12th Street, 15th Street south of 5th Avenue, 17th Street, and 19th Street.
2. Master Plan Development (MPD). See Sec. 35-3908(b)(4) for new primary street designations within an MPD.
3. One Primary Street Frontage Required. All lots must treat at least one street frontage as primary. For example, a lot frontage only by one non-primary street must treat that frontage as primary. A lot fronted by two non-primary streets must treat at least one frontage as a primary frontage.
b. Waterfront. Lots with frontage along the Mississippi River must treat facades facing the waterfront as primary frontages in addition to any primary street frontage.
1. Primary build-to zones must be measured from the edge of any existing, established, or required trail easement into the lot.
c. Civic or Open Space Frontage. Lots containing or abutting civic spaces or public open spaces must treat frontages abutting that space as primary frontages, unless otherwise approved by an administrative adjustment (see Sec. 35-3909(d)). Civic spaces are any spaces required by a Master Plan Development per Sec. 35-3908 and public open spaces include any parks, outdoor cultural spaces, or CV-2 zoned parcels with outdoor plazas or other gathering spaces.
d. Through-Lots with Two Primary Frontages.
1. Where a parcel extends from one primary street through the block to another primary street, each street must be treated as a primary frontage, unless otherwise approved as a design adjustment (see Sec. 35-3909(e)).
2. Any through-lot facing any residential zoning district per Division 2 of Article III across a street must incorporate the following:
i. Within the first 30 feet of lot depth across from any residential zoning district primary frontage, all regulations of a General or Row Building type.
ii. Uses permitted in those building types except no retail or consumer service category uses are allowed.
3. A design adjustment (see Sec. 35-3909(e)) may be approved for a different configuration.
e. Intersecting Primary Streets. Where two primary streets intersect on the subject lot, the following applies:
1. The following hierarchy of streets shall apply, in order: 19th Street, 5th Avenue, 15th Street, 6th Avenue, 12th Street, 17th Street.
2. Except at intersections involving the above streets, the development may treat either as the primary frontage.
f. Non-Primary Frontage. A non-primary frontage is a street frontage that is not considered a primary frontage.
1. Non-primary frontages allow for a lower level of facade treatment as well as permit locations for garage and parking lot driveways entrances.
2. Non-primary frontages may always be treated at the higher level of a primary frontage.
g. Alleys. For the Moline Centre districts, alleys are not considered "streets" and, therefore, cannot be a primary frontage, nor are they required to be treated as non-primary or street frontages.
(5) MINIMUM STREETSCAPE AREA.
a. Purpose. A minimum area between the street pavement and the lot line is required to ensure adequate pedestrian facilities are provided along all streets, including, at a minimum, sidewalks and street trees.
b. Build-to Zone Measurement. Where the area from the back of curb to the lot line along any portion of the frontage is less than 12 feet, the build-to zone must be measured starting from 12 feet off the back of curb/edge of pavement into the lot. The result is the building will be located such that the pedestrian area is at least 12 feet deep. The back-of-curb measurement must be taken along the typical street segment and must not include any bump-outs at street corners. See Sec. 35-3903(l)(5) for measuring build-to zones.
d. Easement. When the sidewalk is less than 6 feet in clear width, an easement is required to ensure a full 6-foot sidewalk is publicly available.
e. Adjustment. A design adjustment (see Sec. 35-3909(e)) may be approved for this requirement, provided the resulting streetscape area is at least 8 feet in depth.
(6) TREATMENT OF YARDS. All yards must consist of landscape areas, terrace space, or sidewalk space, unless otherwise expressly stated, designed for people. See Sec. 35-3907 for landscape and site design regulations and Sec. 35-3903(m) for definition of yards. The following defines how vehicular areas may occur in yards:
a. Parking Locations. Paved vehicular areas (parking lots, loading areas, drives) are located per the building type regulations. Minimum side and rear setbacks of parking must be landscaped.
b. Side Yard Parking Lots. Some building types allow side yard parking lots. Side yard parking lots must not encroach into any street yard or minimum side setback, except as otherwise expressly stated.
c. Driveways Crossing Yards. Paved vehicular areas are limited to specific locations per the applicable building type regulations. Driveways may cross through yards as follows:
1. Where access is allowed from a street to the lot, driveways may cross perpendicularly through the primary or non-primary street yards, except as otherwise expressly stated.
2. In all districts, driveways may cross perpendicularly through the side and rear yards to connect to parking on adjacent lots.
(7) REFUSE & RECYCLING LOCATIONS. Unless otherwise defined by the building type, all refuse, recycling, and other waste areas must comply with the regulations of this subsection, Sec. 35-3903(f)(7). Recycling includes any donation collections containers for clothing or goods.
b. Other Yards.
1. When no rear yard exists or when the rear yard is less than 5 feet in depth, refuse, recycling, and other waste areas may be located in the rear portion of an interior side yard.
2. When no rear or side yard exists, refuse, recycling, and other waste areas, a design adjustment (see Sec. 35-3909(e)) may be approved for locating containers in the non-primary street yard or in the street right-of-way with a license agreement per Sec. 28-2108. In no case shall containers or a refuse, recycling, or other waste area be located in a primary street yard.
3. See Sec. 35-3907(l) for required screening of refuse, recycling, and other waste areas.
c. Interior Location Access Doors. Refuse, recycling, and other waste areas must be located inside the building with access doors off the rear or interior side facade.
1. Access doors may be located off a non-primary street facade if no other option exists.
2. Access doors must be opaque, screening a minimum of 80% of the opening.
3. Carts, dumpsters, and containers must be located immediately inside the access doors and stored inside until the process of emptying.
4. Carts, dumpsters, and containers may not be pulled out of the storage area in advance of the arrival of the hauling truck.
(8) LOADING LOCATIONS. Unless otherwise expressly defined by the building type, all loading areas must be located as follows.
a. Rear Yard. All loading activities must occur in the rear or interior yard.
b. Access Doors and Docks. All loading docks and access doors must be located on a rear facade or interior yard facade.
(g) STOREFRONT BUILDING TYPE.
(1) DESCRIPTION AND INTENT. The Storefront Building type is intended for use along corridors to accommodate shopping, services, and eating establishments in a mixed-use building. Oriented to the street with narrow or no side setbacks, this building type's streetwalls help define the public space of the street. Ground-story storefront glass, entrances along the sidewalk, and windows in upper stories facing the street make these buildings interesting and inviting to pedestrians. Parking is located internally or in the rear yard.

(l) M E A SURING BUILDING TYPE REGULATIONS. The following measuring instructions and additional information applies to the building type regulations in this Division 9.
(1) FRACTIONS AND ROUNDING GENERALLY. When calculations required under this Division 9 result in fractions, any fractional result of less than one-half of the unit of the regulation is rounded down to the whole number and any fractional result of one-half or more of the regulation unit is rounded up to the whole number. For example, if the maximum regulation is 2 feet, a measurement of 1.5 feet (or 1-foot, 6 inches) is rounded up to 2 feet and a measurement of 1.25 feet (or 1-foot, 3 inches) is rounded down to 1 foot. If the maximum regulation is in inches, fractions are rounded to the nearest inch.
(2) GENERALLY PARALLEL & PERPENDICULAR. "Generally parallel," when stated related to lot lines or building facades, means less than 45 degrees off the lot line or facade. "Generally perpendicular," when stated related to lot lines or building facades, means 45 or more degrees off the lot line or facade in any direction.
(3) LOT WIDTH. Lot width is the horizontal distance measured along the minimum front setback line between the side lot lines of a lot. If no minimum front setback is required, lot width is measured along the front lot line.
(4) PRIMARY STREETWALL.
a. Definition. The minimum amount of building facade required along and generally parallel to a primary street frontage, and built within the build-to zone. A streetwall refers to the building facade along the street, creating an edge to the streetscape area.
b. Measurement: Primary Streetwall Minimum Percentage. The primary streetwall percentage is measured as the width of the principal structures within the primary build-to zone, divided by the length of the lot line parallel to the primary street, minus the minimum side setbacks. The streetwall percentage must be greater than or equal to the minimum required percentage in the building type regulations. See Figure 3903(l)-A.
c. Measurement: Maximum Primary Streetwall. The primary streetwall width is measured as the width of the principal structures within the primary build-to zone. The streetwall width must be less than or equal to the maximum streetwall width allowed in the building type regulations.
d. Height. The streetwall or building facade being measured must meet the minimum height required for the building type. See Sec. 35-3903(l)(9)a.
e. Courtyard and Other Allowances. Courtyards and other allowances may be listed in the supplemental regulations for the building type as required or allowed, and may be counted towards the streetwall as expressly stated. The length of the courtyard opening or any allowed, expressly stated expanded build-to zone is measured in the build-to zone, generally parallel to the primary facade.
(5) SETBACKS AND BUILD-TO ZONES.
a. Measurement: Buildings. Required setbacks and build-to zones are measured from the applicable lot line, right-of-way line, or specific location referred to in the applicable regulation, into the lot. For minimum setbacks, the nearest exterior building walls generally parallel to the subject line are used. For build-to zones, the entire facade must be located in the allowed zone, no closer than the minimum required dimension and no farther from the lot line than the maximum required dimension.
1. Street (primary and non-primary) setbacks and build-to zones are measured from the actual right-of-way line of the street or street lot line into the lot. For example, a build-to zone range of 5 to 10 feet would start 5 feet from the street lot line and end 10 feet from the street lot line, resulting in a 5-foot deep zone. (Alleys are not considered streets and typically abut side or rear lot lines.)
2. Side or interior-side setbacks are measured from the nearest side lot line that does not abut a street into the lot.
3. Rear setbacks are measured from the rear lot line into the lot.
4. On corner lots, the required primary or non-primary setback must be provided for each street frontage, depending on whether the abutting street is a primary or non-primary street. The lot line opposite of the primary street is the rear lot line, requiring a rear setback. The lot line generally perpendicular to the primary street is the side lot line, requiring a side setback.
5. On through-lots, the required primary or nonprimary setback must be provided for each street frontage, depending on whether the abutting street is a primary or non-primary street. (See Sec. 35-3903(m) for definitions.)
b. Minimum Required Streetscape Area. See Sec. 35-3903(f)(5) for regulations requiring a minimum streetscape area. Where the minimum area does not exist, the build-to zone is measured from the edge of the expanded streetscape area into the lot.
c. Exceptions to Build-to Zones. Upper-story recessed balcony facades are not required to be located within the build-to zone.
d. Allowed Encroachments. Allowed encroachments into setbacks or beyond build-to zones are as follows, unless otherwise established in the building type regulations:
1. Minor Building Projections in All Yards for All Building Types. Roof overhangs, eaves, chimneys, bays, and other architectural features, such as cornices, may encroach up to 18 inches into any yard no closer than 1 foot from the lot line.
2. Steps and Ramps in Front Yards. Steps and ramps in front yards may encroach fully into any yard up to within 1 foot of any lot line.
e. Setbacks on Irregular Lots. Setbacks are measured from lot lines towards the center of the lot as follows:
1. When lot lines are curvilinear, setbacks must be measured parallel to the curvilinear lot line.
2. When there are multiple rear lot lines, the rear setback must be measured from each of rear lot lines.
f. Waterfront. A river or trail frontage build-to zone or setback is measured from the required trail easement or right-of-way into the lot perpendicular to the easement or lot line. See Sec. 35-3907(h) for waterfront frontage trail easement.
g. Measurement: Elements Other than Buildings. Minimum setbacks that apply to elements other than buildings (e.g. parking areas, fences, storage areas) are measured from the lot line, right-of-way line, or specific location referred to in the applicable regulations, to the nearest point of the feature.
(6) SITE COVERAGE. Site coverage is measured as the percentage of a lot covered by impervious surfaces. See Figure 3903(l)-E.
a. Impervious Surfaces. Any land or portion of a site covered by constructed features that prevent the direct percolation of surface water into the underlying earth. Examples include buildings, paved parking and roadways, masonry walls and terraces, swimming pools, sidewalks, hard surface playing courts, and paved driveways.
b. Semi-Pervious Materials. Semi-pervious materials, such as semi-pervious pavers, semi-pervious asphalt, and semi-pervious concrete, counts towards the site coverage at a lower rate. The area of the semi-pervious materials is added into the overall site coverage at 75% of the actual area. For example, if the area of semi-pervious materials measures 1,600 sq. ft., 1,200 sq. ft. (75% of 1,600) contributes to the lot's maximum site coverage.
c. Green Roofs. Green, or vegetated, roofs count towards the site coverage, calculated at 75% of the area of the green roof. For example, if the surface of the green roof measures 13,000 sq. ft., then 9,750 sq. ft. (75% of 1,600) contributes to the lot's maximum site coverage.
(7) INTERNAL PARKING OR ATTACHED GARAGE PARKING.
a. Intent. The setback is intended to promote the use of the area directly behind the primary facade of any building for people and not the parking of vehicles.
b. Internal Parking or Attached Garage Setback Measurement. Internal parking or attached garage setbacks are defined in the building type regulations.
c. Dimensional Setback. When the building type regulation includes a dimensional setback for internal parking or an attached garage, the setback is measured from the primary facade of the building, located generally parallel and facing the primary lot line.
d. Setback Use. The use of the space of the building within the setback must be occupied space. See definition.
e. Internal Parking Door Location. Any garage door must be located on one of the designated facades of the building.
(8) LIMITED SIDE YARD PARKING. Where allowed, limited side yard parking is located in the interior side yard and must be configured as one double- or single-loaded aisle of parking with the centerline of the aisle located perpendicular to the street.
(9) BUILDING HEIGHT. See Figure 3903(l)-C.
a. Minimum Height. Each building type requires a minimum number of stories. The building must meet the minimum required height along all primary street facades and for a depth of at least 30 feet into the building. All building facades located within the build-to zone must meet the required minimum building height, occupying the same plane. For example, with a minimum height of 2 stories, the street facade of the second story may not be set back from the first story.
b. Maximum Height. Maximum heights are specified in number of stories. This requirement applies to the entire building. The maximum number of stories may not be exceeded due to sloped sites. Heights must step with the grade in order to not exceed the maximum allowable height. See Figure 3903(l)-F.
c. Towers. When expressly allowed in the building type tables, towers may exceed the overall maximum height of the subject building type (see Sec. 35- 3906(b)(6)).
d. Height to Eaves. Eave height is measured from the floor elevation of the first floor to the eave.
e. Roof Type. Roof types per Sec. 35-3906(b) allowed by building type regulations add additional height to the building.
f. Half Stories. Half stories are stories either located fully within the roof type or in a visible basement.
1. Roof. Where occupied building space is allowed within the roof type (see Sec. 35-3906(b)), any space within the roof and within the floor-to-floor height counts as a half story towards the overall allowable height.
i. The occupiable footprint of half stories in the roof is limited to no more than 65% of the footprint of story below.
ii. Dormers or gabled ends of roofs on half stories are limited to no more than 50% of the facade length of the story below, and must be set back from any street facade a minimum of 9 feet.
2. Visible Basement. See Figure 3903(l)-D. for a diagram and explanation of a visible basement and Sec. 35-3903(m) for definitions of basements and visible basements.
3. Two Half Stories. If a building has both a half story within the roof and a half story that is a visible basement, the combined height of the two half stories is considered one full story in terms of measuring overall height.
g. Basements. See Figure 3903(l)-D. for ill ustration of ba sements and Se c. 35- 3903 (m) for definitions of basements and visible basements.
1. A basement that is not a visible basement does not co unt towards the minimum or maximum height of a building.
2. A basement may contain any use allowed within the building, including those allowed only in upper stories.
h. Story Height. Each story is measured with a range of permitted floor-to-floor heights. See Figure 3903(l)-C.
1. Measurement. All story heights are measured in feet between the floor of a story to the floor of the story above it. Minimum and maximum floor-to-floor heights are required along a minimum of 80% of each facade's horizontal length for each story.
2. Ground Story. When noted as a separate story height, the ground-story height must extend from the primary street facade into the building a minimum of 30 feet. The remainder of the groundstory may meet either the primary frontage groundstory heights or the height range permitted for all stories.
3. Single-Story Buildings and Top-Story Measurement. For single-story buildings and the uppermost story of a multi-story building, the floor-to-floor height is measured from the floor of the story to the ceiling, unless a specific height is provided for a single-story building.
4. Mezzanines. Mezzanines may be included within the allowed floor-to-floor height of any story per the building types, provided the following:
i. Mezzanines extending above the story’s allowable floor-to-floor height must count as a full story in addition to the story below.
ii. Mezzanines occupying more than 30% of the floor area below must count as a full story in addition to the story below.
iii. Where the mezzanine story is located adjacent to a street facade, the street facade transparency requirements of the subject building type must be applied to both the mezzanine floor and the story the mezzanine overlooks.
5. Taller Spaces. Spaces exceeding the allowable floor-to-floor heights of the building type are permitted for a maximum of 20% the length of street facades.
(10) TRANSPARENCY. Governed by the building type regulations, the transparency of a facade is measured for each story separately using 2 regulations: (1) an overall minimum transparency percentage per story, and (2) where applicable per building type, maximum blank-wall segments (per Sec. 35-3903(l)(10)c., below).
a. Definition of Transparency. For the purposes of the Moline Centre districts, transparency is the measurement of the percentage of a facade that contains highly transparent, low-reflectance glass.
1. Storefront. When transparency is required separately for primary street ground-story facades, glass must be a minimum of 60% transmittance factor and a reflectance factor of not greater than 0.25.
2. All Other Windows. Transparency for all window, door glass, and other storefront glass must be a minimum of 50% transmittance factor and a reflectance factor of not greater than 0.25.
3. False Windows. The use of false or faux windows, where the window is visible from the exterior with no opening from the interior, to meet the transparency requirement is not allowed.
b. Measurement. Minimum facade transparency is measured from floor-to-floor of each story separately, except for required minimum ground-story transparency as defined below. See the building type regulations for required transparency by building type.
1. Transparency requirements must be met with windows or glass in doors that comply with applicable transmittance and reflectance factors.
2. The measurement may include the frame, mullions, and muntins, but may not include trim or casing.
c. Blank-Wall Segments. Where applicable per the building type regulations, blank-wall segments on all facades must meet the following:
1. No rectangular areas greater than 30% of a story’s facade, as Measured floor to floor, may be blank wall, without transparency. See Figure 3903(l)-H.
2. No horizontal segments of a story’s facade greater than 15 feet in width may be blank wall, without transparency. See Figure 3903(l)-H.
d. Minimum Ground-Story Transparency. When a separate minimum ground-story transparency is required per the building types requirements, the ground-story transparency is measured between 2 feet and 10 feet from the average grade at the base of the facade.
e. Mezzanines. Mezzanines treated as a separate story per Sec. 35-3903(l)(9) must include upper-story transparency required per building type.
f. Tall Stories. Stories that are 18 feet or taller in height must include additional transparency consistent with the following standards. See Figure 3903(l)-J.
1. Separate Ground-Story Transparency Required. When a separate minimum ground-story transparency is required per building type, the facade design must fulfill that requirement in addition to the minimum transparency for the remainder of the ground-story.
2. No Separate Ground-Story Transparency Required. Where no separate ground-story transparency is required per building type, a tall story is treated as 2 separate stories, divided in half horizontally, with the minimum transparency applied to each half.
g. Half Stories. All half-story facades located within the roof structure and within visible basements must meet the minimum required transparency.
(11) BUILDING ENTRANCES. Entrances must be provided consistent with the entrance location and number requirements established for the subject building type and consistent with Figure 3903(l)-K.
