Z2024040 PZ Handout Memo

DATE:
January 7, 2025
TO:
Planning & Zoning Commission  
From:
Paola Jaramillo, Planner  
SUBJECT:
Z2024040 – Sun Basin III     
Agenda Item: 5
 
Staff has received a request from the applicant for an update of conditions ‘c.1 – c.3’ of 
the staff report for the inclusion of additional area for non-development on approximately 
18 acres and also an amendment to condition ‘b’ to include the Enhanced Setback Exhibit 
dated 12/24/24.
The requested changes are as follows:
b. A Plan of Development is approved subject to site plan entitled “Sun Basin III Solar 
Project” consisting of 12 full-size sheets, dated November 2024. The Enhanced 
Setback Exhibit dated December 27, 2024 and stamped received January 7, 2025 
identifies approximately 18 acres which this area will not allow fencing, solar or 
ancillary solar uses. The Plan of Development may be amended administratively 
under separate application as long as the amendment complies with the 
established IUPD development standards as approved by the Board of 
Supervisors. 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.
c. The following IND-2 IUPD standards shall apply: 
1. Min. Front Setback: 10’ (Except along Arlington School Road/Narramore 
Road and 339th Avenue where 100’ setback is required, except in 
locations generally depicted on the Enhanced Setback Exhibit, dated 
12/27/24. In these areas, no fencing or solar facilities are permitted.)
2. Min. Side Setback: 10' (Except along Arlington School Road/Narramore 
Road and 339th Avenue where 100’ setback is required, except in 
locations generally depicted on the Enhanced Setback Exhibit, dated 
12/27/24. In these areas, no fencing or solar facilities are permitted)
3. Min. Rear Setback: 10’ (Except along Arlington School Road/Narramore 
Road and 339th Avenue where 100’ setback is required, except in

locations generally depicted on the Enhanced Setback Exhibit, dated 
12/27/24. In these areas, no fencing or solar facilities are permitted)

Good afternoon! 
 
Paola, 
 
Per the exchange below, we would like to request the following revisions to the Stipulations to accommodate the 
inclusion of the Enhanced Setback Area that will restrict development within it.    Please let me know if you need 
anything else. Note that the Exhibit date changed from my exchange with Rachel.  It is actually 12/31/24 and not 
12/27/24.   
 
Draft recommended changes with new language as bold/underline.  
 
b. A Plan of Development is approved subject to site plan entitled “Sun Basin III Solar Project” consisting of 
12 full-size sheets, dated November 2024. The Enhanced Setback Exhibit dated December 31, 2024 and 
stamped received January 7, 2025 identifies approximately 18 acres which this area will not allow 
fencing, solar or ancillary solar uses. The Plan of Development may be amended administratively under 
separate application as long as the amendment complies with the established IUPD development 
standards as approved by the Board of Supervisors. 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. 
 
c. The following IND-2 IUPD standards shall apply:  
1. Min. Front Setback: 10’ (Except along Arlington School Road/Narramore Road and 339th
Avenue where 100’ setback is required, except in locations generally depicted on the 
Enhanced Setback Exhibit, dated 12/31/24. In these areas, no fencing or solar facilities are 
permitted.) 
2. Min. Side Setback: 10' (Except along Arlington School Road/Narramore Road and 339th
Avenue where 100’ setback is required, except in locations generally depicted on the 
Enhanced Setback Exhibit, dated 12/31/24. In these areas, no fencing or solar facilities are 
permitted.) 
3. Min. Rear Setback: 10’ (Except along Arlington School Road/Narramore Road and 339th
Avenue where 100’ setback is required, except in locations generally depicted on the 
Enhanced Setback Exhibit, dated 12/31/24. In these areas, no fencing or solar facilities are 
permitted.) 
 
 
Let us know if you are able to do an addendum to the Commission. We would like to update our presentation to 
include this as well- we will send that shortly (if that works).  Thank you!
