Project Summary: 
 
1. 
The applicant is requesting a Special Use Permit (SUP) to continue operating an automotive repair 
business on the same parcel as his existing residence. The site is located  in the Rural-43 zoning 
district an approximately 1-acre residential parcel located off the western side of 107th Ave. south 
of the Pinnacle Peak Parkway alignment in the Peoria area. The parcel is bordered on the south 
by a vacant Arizona State Land Department (ASLD) parcel and bordered to the west by SRP high 
power lines. The northern neighbor runs a marine automotive repair and a single-family residence 
is located to the east of the subject parcel.  The parcel has a wireless communications facility 
(WCF) located in its southwest corner. The WCF was originally approved under Z2009015 on 
March 10, 2010 and was subsequently upgraded with approvals in 2011 (Z2011112), 2013 
(Z2013069) and 2022 (Z2021177).  
 
2. 
The parcel is located on the top of a raised ‘bluff’ that is the river terrace along the east side of 
the Agua Fria river. The presence of an  elevation difference from the river and the high-power 
electric transmission line creates a natural barrier to potential development west of the parcel. 
This is one of seven parcels located in a small triangular-shaped area formed by the -power lines 
and 107th Ave. The seven parcels to the north are located outside of the City of Peoria and are all 
engaged in commercial, industrial or agricultural uses either primary uses or accessory to 
residential use.  
 
3. 
The automotive repair business is an existing use which received a temporary use permit (TUP) 
in 2023 under TU2023010 for a period of two years. The TUP was intended to seek an exit from 
the site or longer-term zoning entitlement. The owner attempted to coordinate rezoning of the 
seven parcels with those respective property owners, but no such rezoning application was ever 
submitted. The TUP expired on February 28, 2025. A violation case was opened for continued 
unpermitted operation after the expiration of the TUP on August 13, 2025. This SUP application 
was subsequently submitted on November 19, 2025 for the subject parcel only.  
 
4. 
The owner / resident is the only employee and sole operator of the automobile repair business. 
The location is by appointment only and generally open and operational only during daylight 
hours. All repair is done inside the enclosed garage. There is no business signage and it is not 
open to the general public.  
 
5. 
The site has three designated areas for customer parking and excess vehicle storage. Due to the 
operational confines of a single employee run business and automotive repair parts sourcing  
issues, cars are continuously rotating storage locations throughout the property. Parking and 
automotive storage areas allow operational flexibility over traditional striped parking spaces. The 
site is currently screened and fenced with a combination of CMU walls and chain-link fencing. A 
CMU wall exists on the eastern portion of the parcel separating and screening the front of the 
parcel and the neighbor to the east. The north and south parcel boundaries are fenced with a 4’ 
high chain link fence which is damaged along the southern boundary.

Public Participation Summary: 
 
11. 
The applicant has met all required public participation requirements for the application. A letter 
was mailed out to all property owners within 300’ of the subject parcel. Two signs were posted 
on the property in accordance with Maricopa County notification requirements. The applicant 
provided three letters of support from local residents indicating a need for the use in the 
community.  
 
Outstanding Concerns from Reviewing Agencies: 
 
12. 
The Arizona State Land Department reached out for additional information on the case but has 
not provided any comment.  
 
Staff Analysis: 
 
13. 
Staff supports the SUP request. The previously approved TUP allowed the owner to provide a 
‘proof of concept’  which he operated for two years with no new zoning violation complaints or 
known issues. The use of the parcel is similar to neighboring properties with commercial, 
industrial or agricultural operations. The immediate neighborhood is physically separated from 
any proximate moderate-density residential neighborhoods. The parcel to the south is ASLD land 
and currently vacant. Staff proposes improvements to the southern fencing to provide a minimum 
6’ chain-link fence with view slats for additional visual screening to the ASLD parcel and 107th 
Ave.  
 
Recommendation: 
 
14. 
Staff recommends the Commission adopt a motion recommending that the Board of Supervisors 
approve SU250040 subject to the following conditions ‘a’ – ‘i’: 
 
a. 
Development of the site shall be in substantial conformance with the Site Plan entitled 
“Dunch Property SUP Application“, consisting of 1 full-size sheet, dated January 30, 2026, 
except as modified by the following conditions. Staff may determine slight refinements to 
remain in substantial conformance with the approved site plan.  Minor and major 
amendments to the site plan will be determined in accordance with Chapter 3 of the 
Maricopa County Zoning Ordinance. 
 
b. 
Development of the site shall be in substantial conformance with the Narrative Report 
entitled “Special Use Permit Narrative”, consisting of 26 pages, dated March 2026, except 
as modified by the following conditions. 
 
c. 
This special use permit is valid for a period of 10 years and shall expire on June 10, 2036, 
or upon termination of the use for a period of 90 or more days, whichever occurs first. All 
site improvements associated with the special use permit shall be removed within 90 days 
of such expiration or termination of use.   
 
d. 
The following SUP conditions shall apply: 
1. Minimum Screening: 6’ chain link fencing with view slats or screening materials along 
southern parcel boundary.

SU250040 
Page 7 of 7 
2. Minimum Paving: Dust control measures as approved by the Maricopa County Air 
Quality Department 
 
e. 
The following Engineering condition shall apply: 
1. Engineering review of planning and/or zoning cases is for conceptual design only. All 
development and engineering design shall be in conformance with Section 1205 of 
the Maricopa County Zoning Ordinance; Drainage Policies and Standards; Floodplain 
Regulations for Maricopa County; MCDOT Roadway Design Manual; and current 
engineering policies, standards and best practices at the time of application for 
construction. 
 
f. 
Within one (1) year of Board of Supervisor Approval, the applicant shall obtain any required 
commercial Building Permits as applicable for commercial uses pertaining to the Special 
Use Permit.   
 
g. 
Prior to issuance of a building permit and certificate of occupancy, written confirmation 
will be required from the emergency fire protection jurisdiction having authority that the 
site has been designed in accordance with their regulations and requirements, and that 
emergency fire protection service will be provided to the site. 
 
h. 
Noncompliance with any of the conditions assigned to the approval of this Special Use 
Permit by the Maricopa County Board of Supervisors may be grounds for revocation in 
accordance with the requirements and procedures as set forth in the Maricopa County 
Zoning Ordinance.  
 
i. 
The granting of this change in use of the property has been at the request of the applicant, 
with the consent of the landowner.  The granting of this approval allows the property to 
enjoy uses in excess of those permitted by the zoning existing on the date of application, 
subject to conditions.  In the event of the failure to comply with any condition, and at the 
time of expiration of the Special Use Permit, the property may be considered for revocation  
to the zoning that existed on the date of application.  It is, therefore, stipulated and agreed 
that either revocation due to the failure to comply with any conditions, or the expiration of 
the Special Use Permit, does not reduce any rights that existed on the date of application 
to use, divide, sell or possess the property and that there would be no diminution in value 
of the property from the value it held on the date of application due to such revocation or 
expiration of the Special Use Permit.  The Special Use Permit enhances the value of the 
property above its value as of the date the Special Use Permit is granted and reverting to 
the prior zoning results in the same value of the property as if the Special Use Permit had 
never been granted.

OVERVIEW OF PROPOSAL 
David Dunch (the “Applicant”) is the owner of the 
property located at 23004 N. 107th Avenue (the 
“Property” or “Site”), as highlighted in the aerial 
image to the right (Maricopa County parcel number 
200-11-254) The Property is approximately 1-acre, 
zoned RU-43, and contains one structure and a 
wireless communication facility permitted under a 
separate Special Use Permit (Z2021177). Access to 
the Property is provided by an easement extending 
from 107th Avenue. For several years Mr. Dunch has 
operated an automotive repair business out of his 
residence and desires to continue operations. 
The subject Property is located in the continuously 
rapidly growing northwest area of the valley, south 
of Pinnacle Peak Road and west of 107th Avenue, in the Peoria area. As shown on the attached exhibits, 
the immediate surroundings include various residentially zoned parcels that currently operate as jet ski 
repair, horse riding stables, antique wagon fabrication, and RV repair, along with a large cement operation 
to the north and Arizona State Land Department to the south and west. See Exhibit A. The automotive 
repair on the Property is operated entirely indoors, within an existing large garage. Business continues to 
be conducted by appointment only, allowing the owner to limit activity, maintain low traffic levels, and 
operate in a manner that does not function as a public-facing commercial business. 
A Temporary Use Permit (TU2023010) was approved in 2023 to allow this use for two years while the 
surrounding area continued its transition. See Exhibit B. During the two years, the Property owner worked 
with adjacent neighbors to the north to pursue a coordinated zoning entitlement (i.e. Commercial Unit 
Plan of Development (CUPD). Although there was partial interest, the neighboring property owners 
ultimately did not join together to request CUPD as an agreement could not be made. Without a multi-
parcel effort, a CUPD is no longer feasible. Furthermore, rezoning to commercial zoning such as General 
Commercial (C-3) would allow 120-plus commercial uses, many of which are not appropriate for this 
location. For these reasons, a Special Use Permit is the most appropriate request to allow the existing 
usen for this specific use. It is worth noting that just like the TUP request in 2023, no expansion of 
structures or intensity is proposed as part of this request.

PURPOSE OF REQUEST 
Statement of Specific Application  
The Applicant respectfully requests the following: 
1. Special Use Permit to allow for continued operation of an automobile repair business within 
Rural-43 zoning district for 20 years.  
Description of Proposal 
This SUP is solely for the auto repair business which includes accessory outdoor vehicular storage for 
vehicles waiting to be worked on. The wireless facility on site is permitted under a separate SUP 
(Z2021177). 
General Operations 
Employees  
Mr. Dunch is the sole employee of his business. 
Buildings 
The primary building on site is the residence.  In conjunction with the residence, there are two 
garages, a carport, and an open structure. The business uses the enclosed.  All work on the 
vehicles is done within the southern garage.   
 
Primary Residence: +/- 2,060 SF 
Covered Patio: +/- 195 SF 
Garages: +/- 1,465 SF 
Carport: +/-430 SF 
Detached Structure: +/- 600’ 
Hours of Operation  
The business is open Monday-Friday from 10:00am-4:00pm.  The business is not open to the 
public, but by appointment only. Vehicles needing repair are dropped off or picked up during 
daytime hours. Mr. Dunch works on the vehicles within the enclosed garage as he is available.   
Signage  
The site currently meets the lighting standards within the Maricopa County Zoning Ordinance 
(MCZO). There is no signage identifying the business, as this business is not open to the public, 
but by appointment only. 
Lighting 
The site currently meets the lighting standards within the Maricopa County Zoning Ordinance 
(MCZO). All work is done in the daytime and is done indoors with no additional lighting 
necessary.   
RU-43 Building Setbacks  
The site meets current Maricopa County standards found within the MCZO for RU-43.

Front: 40’ Required, 40’ Met 
Rear:  40’ Required, 40’ Met 
Side:  20’ Required, 20’ Met for Primary Building 
            3’ Required, 3’ Met for Detached Structure 
Screening 
The Property is located in a rural County Island with large parcels, utility corridors, and a mix of 
residential and accessory commercial uses. As shown on the aerial exhibit below, the 
surrounding context does not include nearby residential neighbors that would typically require 
enhanced screening. 
Existing fencing consists of 4’ chain-link fencing along the side and rear property lines, which is 
consistent with other properties in the area. There is an 8’ tall CMU fence on the east property 
line.   
To the west and south, the Site abuts Arizona State Land Department (ASLD) land that is 
undeveloped and constrained by the Agua Fria River and multiple 500 kV transmission lines. 
These conditions make future development unlikely. There are no residences in these directions 
that would benefit from additional screening. 
To the north, the adjacent property contains an ATV/UTV and jet ski repair operation with 
outdoor vehicle storage, with a large concrete plant located further north. These uses are similar 
to or more intensive than the proposed use and do not function as traditional residential 
neighbors. 
To the east, the Site does have an 8’ CMU wall that screens the commercial use from the 
residence to the east and from 107th Avenue.  Additionally, the Site is visibly blocked by another 
residence. Lastly, the roadway provides physical and visual separation, and the business is not 
open to the public, has no signage, and operates entirely indoors. 
Given the lack of true residential uses, additional screening such as an 8-foot solid wall around 
the entire site is not necessary and would be inconsistent with the rural character and 
commercial uses west of 107th Ave.

For these reasons, the existing fencing and site conditions provide adequate compatibility with 
surrounding properties.  
Paving 
The proposed Special Use Permit does not warrant traditional commercial paving. The 
automotive repair operation is extremely low intensity, with only one vehicle being serviced at 
a time and all repair activity occurring indoors within an enclosed garage. At most, one vehicle 
per day is delivered to or picked up from the Site by appointment only. The business is not open 
to the public, has no signage, no advertising, and no direct frontage on 107th Avenue, 
eliminating passerby traffic or incidental visitation that would otherwise necessitate paved 
parking or circulation areas. 
Consistent with the surrounding rural residential character of this County Island area, the 
Property is not fully paved. Instead, decomposed granite (DG) is used along the access easement 
from 107th Avenue and within the front portion of the Site where the client cars are located. 
This treatment functions as effective dust control while reflecting the prevailing development 
pattern for similar rural residential properties in the area that support accessory commercial 
uses. Of the seven nearby properties with comparable uses, only one is fully paved, reinforcing 
that packed dirt and DG is the customary and accepted dust-proofing method. 
The rear portion of the Site consists of hard-packed native soil. Adding DG or asphalt paving to 
the rear is not necessary as the commercial component is not in the rear and would be 
inconsistent with the established character of the surrounding area. 
Accordingly, the existing dust-controlled surface treatment is appropriate for the proposed use 
and adequately addresses health, safety, and compatibility in the rural setting.  
Parking 
Parking for the auto repair use is located on the eastern portion of the Property, directly in front of 
the residence and garage where all repair work occurs. The parking area is separated from 107th 
Avenue and adjacent properties by an existing 8-foot block wall, which effectively screens vehicles 
from public view and shields daytime running lights from surrounding properties and 107th 
Avenue.  
Since the business operates by appointment only and is not open to the public, a maximum of four 
to five customer vehicles are present on site at any given time. Vehicles are dropped off and 
picked up during daytime hours (Monday-Friday, 10:00am-4:00pm), resulting in extremely limited 
trip generation. There is no employee parking demand beyond the property owner. 
Access to the parking area is provided via the existing 20-foot-wide access easement from 107th 
Avenue. The access drive and parking surface consist of decomposed granite (DG), which provides 
adequate dust control consistent with rural development patterns in the surrounding County 
Island area.  
Given the limited number of vehicles, indoor repair operations, existing screening wall, daytime-
only activity, and dust-controlled surface treatment, the parking configuration is appropriate for 
the requested Special Use Permit and remains compatible with the rural character and 
surrounding uses.

RELATIONSHIP TO SURROUNDING PROPERTIES 
There are essentially no adjacent neighbors to the west and south. Neighboring properties to the north, 
all zoned RU-43 contain businesses as well. Across 107th Avenue is a residential subdivision located within 
the City of Peoria limits. The surrounding properties, uses and zoning are as follows:

LOCATION AND ACCESSIBILITY 
The Property is located approximately 3 miles south and east of the Loop 303 and Happy Valley Parkway 
intersection in the Peoria area. The Site is accessed via a 20’ easement that allows access from 107th 
Avenue to the Property. 
CIRCULATION SYSTEM (ON SITE AND OFF) 
The Site is accessed via a 20’ access easement (PK 498, Page 5 MCR) from 107th Avenue. As stated earlier, 
this business is not open to the public. Vehicles are dropped off and picked up in the parking area in front 
of the house that already consists of DG.  No circulation of customer vehicles occurs in the rear yard, solely 
the front yard.  
DEVELOPMENT SCHEDULE (PHASING) 
The Property is currently developed.  No additional development is planned.

Temporary Use Permit

Temporary Use Permit Summary:  
 
The property owner agent, Ashley Marsh, is requesting a Temporary Use Permit to allow 
temporary on-site automotive repair home business on parcel # 200-11-254 in the Rural-43 
zoning district. The subject site is located at 23004 N. 107th Ave. in the Peoria area.  
 
The temporary proposal is classified as Other Uses under Article 1302.2.9. of the Zoning 
Ordinance, which are determined by the zoning inspector. On February 23, 2023, the Zoning 
Administrator, Daren Gérard, AICP, declared that the request to use the site for a temporary 
automotive repair business would qualify in the Other Uses category with a condition that 
after two-years, if the use of the site continues, will require either a secured Special Use 
Permit or zone change approved by the Board of Supervisors.   
 
The property owner, David Dunch, will repair the vehicles in a large existing garage 
adjacent to the property’s single-family residence, where the property owner resides. 
Business is done by appointment only with hours set by the homeowner operating more like 
a home business than a typical commercial business.  The property owner is searching for a 
new commercial or industrial site that would be more appropriate in the long term and that 
is why the request is for a two-year TUP which will enable the property owner to either 
relocate the operation or process entitlement to allow the automotive repair business on 
the site.  
 
Staff research found no outstanding fees owed on the property. Currently, there is one code 
violation on the property (V202200070) for running a business on site without entitlement; 
however, this TUP will temporarily remedy this violation.  In the long-term, a condition will be 
added to this TUP stating that after two years the property owner must cease operation and 
prior to expiration obtain a secured approved entitlement that would permanently remedy 
the V202200070 code violation.  
 
The site has been posted in accordance with MCZO 1302.3.1.3. with the required 10 day 
posting period. The site was posted on February 14, 2023, and the 10 days expired on 
February 24, 2024. Staff did not receive any public opposition to the application. A copy of 
the Posting Certificate has been placed in the case file along with photographic evidence

Re: 
23004 N 107th Avenue - Temporary Use Permit Request 
To Whom it May Concern: 
 
On behalf of David Dunch, the property owner of 23004 N. 107th Avenue, (the “Property”), we are 
requesting approval of a Temporary Use Permit for an automotive repair business. Mr. Dunch currently 
resides on the Property, which is approximately 1-acre and zoned RU-43. The Property currently contains 
one structure and a wireless communication facility, permitted under a separate Special Use Permit. 
Access to the Property is provided by an easement extending from 107th Avenue.  
 
The subject Property is located in the rapidly growing 
northwest area of the valley.  Specifically, the 
Property is located south of Pinnacle Peak Road and 
west of 107th Avenue, in the Peoria area, as shown on 
the aerial to the right. It is anticipated that the subject 
Property and surrounding properties will eventually be 
redeveloped as new commercial and residential 
development close in around the Property.  During 
this transition, the Property owner is requesting a 
Temporary Use Permit to continue his automotive 
repair business on the premises.  This use is currently 
compatible with the existing surroundings and uses on 
the adjacent northern residentially zoned properties, 
which appear to include a jet ski repair, horse riding 
stables, antique wagon shop and RV repair.  See 
attached Exhibit A for context photos.  Additionally, 
to the immediate west is a large mining operation.   
See Exhibit B.  It is anticipated that as the area transitions, the immediately adjacent uses may also transition.  
A Temporary Use Permit will allow for what is currently an appropriate use for the Property whereas a hard 
rezone or Special Use Permit would allow for long-term uses that may not be compatible with future 
development. 
 
The automotive repair use is entirely conducted indoors, in an existing, large garage.  Business is by 
appointment only, allowing Mr. Dunch to work on his own hours and not operate as an open to the public 
commercial business.  As the area transitions, the Property owner is looking for a new space that would be

better suited in the long term. Here, we are simply asking for a Temporary Use Permit for a time limit of two 
(2) years to allow for either the relocation and/or reevaluation of the automotive repair use at a later date. 
 
We respectfully request the approval of this Temporary Use Permit as it is currently compatible with the 
surrounding uses and is temporary in nature so that it does not interfere with the future redevelopment of the 
area.

Date
Applicant is requesting Traffic Impact Study (TIS) waiver for a Special Use Permit Application (SU250040). As per the applicant, the project involves the continued operation of a small 
automotive repair activity that operates strictly by appointment only, resulting in very limited and predictable trip generation. Accordingly, peak-hour trip generation is anticipated to be 
approximately 1 to 2 trips, which is well below the 5 peak-hour trip threshold typically used by the MCDOT to warrant preparation of a TIS. The site is located on parcel (APN # 200-11-254).

Dear Maricopa County Officials: 
Please accept this letter of support for David Dunch’s auto repair business operated from his 
residence at 23004 N. 107th Ave. 
As the property owner a few parcels to the north (23024 N.107thAve.), and former Mayor 
of Phoenix, I have seen firsthand how this part of the community has developed and 
functioned over the years. This area has a unique character, with county island properties 
adjacent to state land, cement plants, transmission corridors, and a longstanding pattern of 
residents operating small-scale commercial activities from their homes. David’sbusiness is 
consistent with the established character west of 107thAvenue.  
David has been a valuable member of the community and a respectful neighbor. His auto 
repair business is quiet, well managed, and professional.  He operates by appointment only 
with no signage and virtually no traffic.  It has remained compatible with the neighborhood.  
I believe this business is an appropriate and practical fit for the area and provides a useful 
service to nearby residents. I urge you to respectfully approve his Special Use 
Permit request.  
Thank you,
