Site engineering comments are as follows:

1. A block plat may be submitted to combine the lots previously recorded by the “Kolb Commercial Subdivision Lots 1 thru 4.” A drainage report is required to support the abandonment of the northern drainage easement.

Site Zoning REVIEW COMPLETED CDRC TRANSMITTAL

TO:
Planning & Development Services Department

FROM: Fernando L. García
PDSD Zoning Review Section

PROJECT:
3901 S Kolb Rd, Tucson, AZ 85730
Parcel(s): 136384180, 136384170, 136384160, 136384150
Current Zoning: C-1
TP-PRE-0525-00087

TRANSMITTAL DATE: May 14, 2025

1. Any proposed development must comply with the City of Tucson Unified Development Code (UDC) Administrative Manual Chapter 2-06 – Development Package (DP). Building permits can be submitted and reviewed concurrently with the development package but the building plans cannot be approved until the development package is approved and the building plans are reviewed for consistency.

2. Proof of lot combination of the four component parcels will be required before issuance of the development package (DP).

3. Per UDC Table 4.8-4, the proposed use is: Residential Land Use Group – Family Dwelling (Multifamily Development), which is a permitted use in the C-1 zone.

4. Per UDC Table 6.3-5.A, dimensional standards in the C-1 zone are listed below. For the purposes of determining dimensional standards, a multifamily development is considered “nonresidential”.
a. Residential Density Permitted: 36 dwelling units per acre (one dwelling unit for every 1,210 sf)
b. Maximum building height (nonresidential; as measured from design grade): 30’
c. Maximum lot coverage (nonresidential): N/A
d. Perimeter Yard (as measured from property line):
i. Per UDC 6.4.5.C.2, nonresidential development abutting a Major Street & Road (MS&R), S Kolb Rd in this location, requires a 10’ setback from the property line.
ii. Interior setback to a residential zone (to any SR or R-2 zone within 20’ of the property line, including across an alley or street): 1.5 times the height of the adjacent wall. The setback to the east and north appear to be insufficient without an approved setback reduction. A setback reduction can be requested through a Design Development Option (DDO) application submitted after the first formal review.

5. The original plat for this subdivision (available at https://maps-and-records.tucsonaz.gov/subdivisions/search?book=28&pg=010) demonstrates a number of easements, including access, no-access, utility, and drainage, that conflict with the placement of buildings and driveways for this project. A block plat, to vacate these easements (and concurrently, combine the lots) will be necessary to submit and approve prior to final approval of the development package for this project.

6. Per UDC Table 7.4.4-1, for “multifamily dwellings – 0-70 units/acre”, the motor vehicle parking requirements is based on the number of bedrooms in each unit as follows:
a. 1 bedroom - 1.50 spaces per dwelling unit

Based upon 28 one-bedroom units, 42 parking spaces are required on site; of these 42, two must be accessible; of the two accessible spaces, one must be van accessible
b. Parking calculations below are an estimate based upon information provided on the submitted plans and may be incomplete, or incorrect, based upon the veracity or clarity of the information provided in the plans.

7. Motor vehicle use areas must be designed in accordance with UDC 7.4.6, to include required parking area access lane (PAAL) widths for one and/or two-way lanes.

8. Per UDC Table 7.4.8-1, bicycle parking requirements are as follows:
a. Multifamily Dwellings and Group Dwelling:
i. Short-Term Bicycle Parking: 0.10 spaces per bedroom; for 28 one-bedroom dwellings, the requirement would be 3
ii. Long-Term Bicycle Parking: 0.5 spaces per bedroom; for 28 one-bedroom dwellings, the requirement would be 14; these spaces can be located in common areas or within individual units
b. Ensure bicycle parking design is consistent with UDC Section 7.4.9.

9. Per UDC Table 7.4.11-1, multifamily dwellings require no parking spaces to be EV Installed, 10% to be EV Ready, and 20% to be EV Capable.

10. Ensure pedestrian access standards found in section 7.8 of the UDC and sections 7-01.0.0 and 10-01.0.0 of the Technical Standards Manual are met.

11. The comments provided are preliminary and are not to be assumed as a complete review of the proposal. During the Development Package review process, the Zoning Review Section will conduct a full review to assure compliance with applicable UDC development criteria and technical standards.

TW New Area Development REVIEW COMPLETED TP-PRE-0525-00087 - Pre-Application Conference Review v1 – 3901 S KOLB RD

Tucson Water offers the following comments for your convenience:

1. Please see Tucson Water’s NW321415 valve map to see the public water mains in Kolb Road that front this group of parcels. Copies of the valve map(s) and/or ‘as-built’ plan(s) referenced in these comments may be obtained from Tucson Water’s Mapping & GIS Center by sending an e-mail request for them to TWMapInfo@tucsonaz.gov.

2. An existing 6” public water main stub-out and a fire hydrant was constructed to serve this property under Tucson Water Plan No. 154-1982. These are shown on Sheet 5 of this plan.

3. The water pressure in this area at ground level (based on elevation) is estimated to be in the 67 to 74 psi range.

4. Tucson Water will allow this project to be served by a single master water meter that discharges to a private water distribution system. Tucson Water also recommends (but is not requiring) that each individual dwelling unit be equipped with its own private sub-meter.

5. The required size of the master water meter for this project will need to be determined by a water fixture count conducted in accordance with the 2018 International Plumbing Code and Tucson Water’s Water Meter Sizing Guidelines. Tucson Water’s Water Meter Sizing Guidelines are available at https://www.tucsonaz.gov/files/sharedassets/public/v/1/city-services/tucson-water/documents/signed_meter_sizing_guidelines_march_2020.pdf.

6. If a 3” or larger master water meter is needed for this development, the master water meter will need to be located within a large meter enclosure that is a minimum of 25’ long x 10’ wide x 5’ high per Tucson Water Standard Detail SD-314. The entire large meter enclosure must be located on the property in a water easement granted to the City of Tucson.

7. To comply with Tucson Water’s Tucson Water’s Remote Meter Policy No. IV-B.08, Eff. 07/14/2009, these four existing parcels will need to be combined into a single parcel.

8. The submitted site plan shows some of the dwelling units within existing easements. This will not be allowed. The existing easements will need to be are released to utilize the proposed building locations.

9. The Kolb Commercial Subdivision, Lots 1-4 final plat indicates there is a public utility easement created by BK 27, M&P, PG 92 on this property. Please note that the City of Tucson may only release only the City of Tucson’s interest in this public utility easement via a re-subdivision plat. The interests of other public utilities in this public utility easement will need to be released by separate instruments. See Section 11-01.4.0 SUPPLEMENTAL DOCUMENTATION SPECIFICATIONS of the Technical Standards Manual of the City of Tucson’s Uniform Development Code.

10. If and when any new domestic water, irrigation water, or fire water services are needed to serve this proposed development, please contact Tucson Water’s New Services Section by calling 520-791-5164 or by sending an email to TW Common@tucsonaz.gov.
