Good afternoon,
Just in case John didn’t reach out to you all separately, but he has requested to withdraw
BLDG-1538-2025 and to be refunded any remaining fees.
Currently in discussions over a possible ADU application.
Kind regards,

Sorry forgot to reply to all
We wouldn't propose the expansion/alteration of existing, we would create a new
attached Adu with seperate entrance.
Please cancel this application and refund remaining fees.

Unfortunately, in this case, it would not.
Per SLOMC 17.86.020, applications that propose the expansion/alteration of an existing
single-family dwelling for the purpose of creating an ADU is permissible, but said
expansion/alteration must be consistent with all underlying zoning regulations. This is the
section that was recently added to our zoning regulations that allow what originally
required a “two-step” building permit process as a “one-step” process if the proposed
addition/expansion is consistent with zoning regulations. To be consistent with the City’s
regulations you will need to obtain a Director’s Action for the addition to a nonconforming
structure.

I'm assuming making it an ADU gets rid of that issue. I don't know why we bother doing
anything but ADUs anymore, gets rid of most the issues.

Good afternoon,
Kelly – As shown on Sheet AS1.1 (Architectural Site Plan), the existing residence is
depicted to be within the 5-foot minimum side-yard setback along the northern property
line. Per SLOMC 17.16.020(B), properties zoned R-1 require, at minimum, to be
setback 5 feet from all side and rear property lines (setbacks increase depending on
the height of the structure). Therefore, the existing residence is considered to be
nonconforming with the underlying zoning regulations.
John - Section 17.92.020 provides guidelines pertaining to the reconstruction (which
includes modifications/additions) of structures considered nonconforming. Many of the
subsections of 17.92.020 do pertain to the reconstruction of nonconforming structures
involuntarily damaged because such scenarios are often the only instances where the
City would allow a structure to be built/modified in such a way that would make it
nonconforming (exceptions to that would be density bonus and flexible lot design
projects).
The intent of Chapter 17.92, as stated in 17.92.010, is to provide for the correction or
removal of nonconforming structures as soon as practical, but not unduly encumber
maintenance and continued use of otherwise sound structures. Subsection F of
17.92.020 offers the opportunity, via Director’s Action, to allow an addition to a
structure that would otherwise be required to remedy the nonconforming aspect of the
building, given that the applicable findings can be made.

Hi Ethan,
The code your citing has to do with rebuilding a house that has been damaged
17.92.020
Limits on reconstruction—Exceptions.
A. A nonconforming structure that is involuntarily damaged to an extent of seventy-
five percent or more of its replacement cost immediately prior to such damage, as
determined by the chief building official, may be restored only if made to conform.
It is very common to do an addition to an existing house and I've never heard of a
director approval being required to do so.
Please remove this comment.
Thanks
John

Apologies, the comment was made by Ethan Estrada. I have included Ethan.
That being said, we are looking to get a better understanding of the following
comment for BLDG -1538-2025:
Mainly, why is the existing residence considered to be non-conforming?
Thank you,

Hey John,
This comment from Phil D. stipulates that the existing structure is a non-
conforming structure at 619 Grove St. Due to that, we need to obtain approval
through the director's action. Please see the image below of the associated
comment. Let us know how you would like to proceed.
Thank you,

APPLICATION FOR WAIVER OF SOILS TEST FOR MINOR ADDITIONS
TO ONE AND TWO-FAMILY DWELLING UNITS
GENERAL INFORMATION:
Project Address: ___________________________________Application #: _________________
Applicant Name: _____________________________________Phone #: ________________
BACKGROUND: Historically, quantifiable data has been created using accepted soil science
methodologies by approved agencies using approved methods indicating that, in general, the soil
conditions likely to be encountered throughout the City of San Luis Obispo would consist of expansive,
compressible, shifting or other questionable soil characteristics. These types of soil conditions would
require a complete geotechnical evaluation for moderate and major projects.
PURPOSE: In order to help alleviate the burdens of time and disproportionately high cost associated
with obtaining a soil test for minor residential additions up to 500 square feet to one and two family
dwellings, the City of San Luis Obispo Building Division has developed a policy allowing a waiver of the
soil test as specified in the California Residential Code Section R401.4.
POLICY STATEMENT: Where a soils test has not been previously provided in accordance with the
2022 CRC Section R401.4; one and two family dwelling unit residential additions of 500 square feet or
less, up to two stories (addition footprint area), may forego a soils test provided the applicant agrees to the
following checked statements by signing and dating this application in the appropriate location at the
bottom of this application:
An on-site investigation has revealed no foundation failure of the existing residence.
The type of construction proposed meets or exceeds the minimum provisions for wall and
roof-ceiling construction in accordance with the 2022 CRC Chapters 6 and 8.
The foundation system proposed meets or exceeds the minimum requirements in accordance
with the 2019 City of San Luis Obispo Construction and Fire Code Amendments Table
1809.7.
A minimum allowable soil bearing pressure of 1500 PSF has been utilized for the design of
foundation systems as shown in the 2022 CRC Table R401.4.1.
The proposed area of work on the site does not exceed a maximum 20% slope.

PURPOSE: This plan can only be used for minor building projects (SFR - new, remodels, additions; and/or commercial remodels).
Newly constructed commercial buildings under 2019 CalGreen Codes require the development and implementation
of a WPCP similar to the standards of a State submitted SWPPP. This plan is only to serve as a guide, if the
applicant elects to use it. The BMPS specified herein shall be considered just the “Minimum BMPs” and during the
course of the project additional BMPs (Necessary BMPs) may be required to protect water quality. Please note that
an in-fill new single family home project may require additional plan elements. This plan shall be used in accordance with
CGP 2009-0009-DWQ, City Stormwater Permit & 2019 CalGreen Building Codes.

APPLICATION FOR WAIVER OF SOILS TEST FOR MINOR ADDITIONS
TO ONE AND TWO-FAMILY DWELLING UNITS
GENERAL INFORMATION:
Project Address: ___________________________________Application #: _________________
Applicant Name: _____________________________________Phone #: ________________
BACKGROUND: Historically, quantifiable data has been created using accepted soil science
methodologies by approved agencies using approved methods indicating that, in general, the soil
conditions likely to be encountered throughout the City of San Luis Obispo would consist of expansive,
compressible, shifting or other questionable soil characteristics. These types of soil conditions would
require a complete geotechnical evaluation for moderate and major projects.
PURPOSE: In order to help alleviate the burdens of time and disproportionately high cost associated
with obtaining a soil test for minor residential additions up to 500 square feet to one and two family
dwellings, the City of San Luis Obispo Building Division has developed a policy allowing a waiver of the
soil test as specified in the California Residential Code Section R401.4.
POLICY STATEMENT: Where a soils test has not been previously provided in accordance with the
2022 CRC Section R401.4; one and two family dwelling unit residential additions of 500 square feet or
less, up to two stories (addition footprint area), may forego a soils test provided the applicant agrees to the
following checked statements by signing and dating this application in the appropriate location at the
bottom of this application:
An on-site investigation has revealed no foundation failure of the existing residence.
The type of construction proposed meets or exceeds the minimum provisions for wall and
roof-ceiling construction in accordance with the 2022 CRC Chapters 6 and 8.
The foundation system proposed meets or exceeds the minimum requirements in accordance
with the 2019 City of San Luis Obispo Construction and Fire Code Amendments Table
1809.7.
A minimum allowable soil bearing pressure of 1500 PSF has been utilized for the design of
foundation systems as shown in the 2022 CRC Table R401.4.1.
The proposed area of work on the site does not exceed a maximum 20% slope.

Hydraulic Calculation Check — 619 Grove Street, San Luis Obispo, CA
(10-yr, 25-yr, 50-yr, 100-yr), Rational Method + 2" PVC Hydraulics
Contributing Area = 1,041 sf; Runoff Composite Coefficient 𝐶𝐶= 0.55
1) Inputs / Assumptions
Site / Hydrology
• Contributing drainage area, 𝐴𝐴= 1,041 ft²
• Runoff coefficient, 𝐶𝐶= 0.55 (Table 4-7)
• Method: Rational Method (peak runoff rate)
• Rainfall intensity source: SLO Creek Drainage Design Manual (Feb 2003), Table 4-6 (558–609 mm
/hr annual rainfall band), 10-minute duration:
o 10-year: 𝑖𝑖10 =91 mm/hr
o 25-year: 𝑖𝑖25 =102 mm/hr
o 50-year: 𝑖𝑖50 =117 mm/hr
o 100-year: 𝑖𝑖50 =127 mm/hr
Pump / Discharge
• Pipe: 2" PVC (assume 2" Sch 40 ID ≈ 2.067 in)
• Straight pipe length, 𝐿𝐿= 60 ft
• Static head (lift), 𝐻𝐻𝑠𝑠= 0.6 ft
• Friction equation: Hazen–Williams, PVC 𝐶𝐶𝐻𝐻𝐻𝐻=150(typical smooth PVC)
• Minor loss: (1) 90° elbow, assume 𝐾𝐾= 0.9(typical value; varies by elbow radius/type)
Design criterion
• “satisfactory pump rate with rainfall totals” interpreted as: 𝑄𝑄𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝≥ 𝑄𝑄𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖, 𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝
(i.e., pump discharge rate at operating head must be at least peak runoff inflow rate)
2) Conversions
2.1 Area in acres 𝐴𝐴=104143560 = 0.02390 ac
2.2 Rainfall intensity conversion (mm/hr to in/hr) 𝑖𝑖(in/hr)=𝑖𝑖(mm/hr)25.4 𝑖𝑖10 =9125.4 = 3.583 in/hr;𝑖𝑖25 =10225.4 = 4.0157 in/hr; 𝑖𝑖50 =11725.4 = 4.6062 in/hr; 𝑖𝑖100 =12725.4 = 5.0 in/hr
3) Peak runoff inflow (Rational Method)
Rational Method (US customary): 𝑄𝑄(cfs)= 1.008 𝐶𝐶𝑖𝑖�𝑖𝑖𝑖𝑖ℎ𝑟𝑟�𝐴𝐴(𝑎𝑎𝑎𝑎)𝐶𝐶a
Convert to gpm: 𝑄𝑄(gpm) =𝑄𝑄(cfs) × 448.83
3.1 10-year peak inflow 𝑄𝑄10 = 1.008(0.55)(3.583)(0.0239)(1.0) = 0.04748 cfs 𝑄𝑄10 = 0.04748 × 448.83 =21.31 gpm
3.2 25-year peak inflow 𝑄𝑄25 = 1.008(0.55)(4.0157)(0.0239)(1.1) = 0.05853 cfs 𝑄𝑄25 = 0.05853 × 448.83 =26.27 gpm
3.3 50-year peak inflow 𝑄𝑄10 = 1.008(0.55)(4.6062)(0.0239) = 0.07324 cfs 𝑄𝑄10 = 0.07324 × 448.83 =32.87 gpm
3.4 100-year peak inflow 𝑄𝑄25 = 1.008(0.55)(5.0)(0.0239)(1.25) = 0.08281 cfs 𝑄𝑄25 = 0.08281 × 448.83 =37.17 gpm
Minimum pump flow to “keep up” with peak runoff (hydrology requirement):
• 10-yr storm: 𝑄𝑄𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝, 𝑝𝑝𝑖𝑖𝑖𝑖≥21.31 gpm
• 25-yr storm: 𝑄𝑄𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝, 𝑝𝑝𝑖𝑖𝑖𝑖≥26.27 gpm
• 50-yr storm: 𝑄𝑄𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝, 𝑝𝑝𝑖𝑖𝑖𝑖≥32.87 gpm
• 100-yr storm: 𝑄𝑄𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝, 𝑝𝑝𝑖𝑖𝑖𝑖≥37.17 gpm
Rainfall intensities source: SLO Creek Drainage Design Manual Table 4-5.
4) Hydraulic head requirement through 2" PVC (60 ft + 1 elbow)
4.1 Straight-pipe friction (Hazen–Williams; 60 ft)
Hazen–Williams headloss (ft): ℎ𝑖𝑖=4.52 𝐿𝐿 𝑄𝑄1.85𝐶𝐶𝐻𝐻𝐻𝐻1.85 𝑑𝑑4.87
Where:
• 𝐿𝐿=60 ft
• 𝑄𝑄in gpm
• 𝐶𝐶𝐻𝐻𝐻𝐻=150
• 𝑑𝑑=2.067 in
Computed straight-pipe friction losses:
• At 21.31 gpm: ℎ𝑖𝑖≈0.213 ft
• At 26.27 gpm: ℎ𝑖𝑖≈0.314 ft
• At 32.87 gpm: ℎ𝑖𝑖≈0.477 ft
• At 37.17 gpm: ℎ𝑖𝑖≈0.595 ft
4.2 Elbow minor loss (1 elbow)
Minor loss: ℎ𝑝𝑝=𝐾𝐾𝑣𝑣22𝑔𝑔
Using 𝐾𝐾=0.9, 𝑔𝑔=32.2 ft/s2 , 2" Sch 40 ID ≈ 2.067 in:
• Velocity at 21.31 gpm: 𝑣𝑣≈2.04 ft/s ℎ𝑝𝑝,10 ≈0.058 ft
• Velocity at 26.27 gpm: 𝑣𝑣 ≈2.51 ft/s ℎ𝑝𝑝,25 ≈0.088 ft
• Velocity at 32.87 gpm: 𝑣𝑣 ≈3.14 ft/s ℎ𝑝𝑝,10 ≈0.137 ft
• Velocity at 37.17 gpm: 𝑣𝑣 ≈3.55 ft/s ℎ𝑝𝑝,10 ≈0.175 ft
4.3 Total Dynamic Head (TDH) 𝑇𝑇𝑇𝑇𝐻𝐻=𝐻𝐻𝑠𝑠+ℎ𝑖𝑖+ℎ𝑝𝑝
with 𝐻𝐻𝑠𝑠= 0.6 ft
• 10-yr TDH @ 21.31 gpm 𝑇𝑇𝑇𝑇𝐻𝐻10 = 0.6 + 0.213 + 0.058 = 0.871 ft
• 25-yr TDH @ 26.27 gpm 𝑇𝑇𝑇𝑇𝐻𝐻25 = 0.6 + 0.314 + 0.088 = 1.002 ft
• 50-yr TDH @ 32.87 gpm 𝑇𝑇𝑇𝑇𝐻𝐻50 = 0.6 + 0.477 + 0.137 = 1.214 ft
• 100-yr TDH @ 37.17 gpm 𝑇𝑇𝑇𝑇𝐻𝐻100 = 0.6 + 0.595 + 0.175 = 1.37 ft

6) Notes / Limitations for engineering review
1. TDH includes only: 0.6 ft static lift + 60 ft straight 2" pipe + one elbow. Any additional fittings (check
valve, reducer, discharge losses, etc.) will add head.
2. Rational Method peak runoff depends on selected duration (typically near time of concentration). This
check uses 10-minute intensity as a conservative short-duration basis per Table 4-6 for City of SLO.

CWA job: 197
The following are responses to the 1st plan review for the above referenced project; comments from the 1st plan review are provided
below in half-tone for reference, and responses are provided in red font:
California Code Check – Building Review 2022 CBC Comments
Public Works Permit Review v.1 Emma Laplante elaplant@slocity.org 8057817199
1. Comment: 1. Include the following note under Standard Public Works Notes a. All surface and subsurface drainage systems
designed at less than 2% shall have final gradients certified by a licensed surveyor or engineer prior to final inspection approvals.
Response: Note has been added to the Standard Public Works Notes on sheet T1.0 as requested. See note i.
2. Comment: 2. These plans are considered incomplete and additional comments may apply when all minimum plan information
and/or supporting documentation is provided through the plan review process.
Response: Understood.
3. Comment: 3. Update Standard Public Works Notes to reference the December 2025 City standard
Response: Updated. The note now reads “The current adopted standards are dated December 2025”.
4. Comment: 4. A System certification is required from the engineer of record prior to final inspection approvals. The engineer shall
certify that the drainage and stormwater system components have been inspected and are in general conformance with the
Plan Check Response

drainage report, system design, and the approved plans, including all final elevations, component sizing, detention basins, parking
lot detention curb elevations, drainage piping, inlets, weir elevations, and orifices
Response: Understood
5. Comment: 5. No project type is checked on the Stormwater Control Plan for Post Construction Requirements, please revise.
Response: Multi-Unit Residential is now checked on the SWCP.
6. Comment: 6. Clarify the Proposed drainage strategy
a. If physical obstructions or lot lines prohibit 10 feet of horizontal distance, 5% slope shall be provided to an approved alternative
method of diverting water away from the foundation. Swales used for this purpose shall be sloped a minimum of 2% along the
flowline.
b. Revise the invert elevations to provide a minimum 2% gradient if practical. As an alternative, the gradients may be reduced to
not less than 1% when verified by a licensed surveyor or engineer. This is including the outlet pipe to the street.
c. Show limits of sidewalk restoration from score mark to score mark for this sidewalk underdrain
d. Provide details and calculations for hydrologic assessment and sump pump capacity. The proposed engineered drainage system
will require the engineer of record to certify the system is built in conformance with the system design and approved plans prior to
final inspection.
Response:
a) Swales with a 2% slope have been added to prevent watershed from flowing across the property line. This swale diverts
water to all three catch basins which will then divert water up to Grover Street through the drainage sump pump.
b) All elevations have been updated to allow for the flow of collected watershed to the drainage sump pump, with a minimum
of a 1% flowline between grates. Furthermore, we have shown newly proposed topography lines (330’ and 331’) in order
to allow this drainage to occur properly.
c) Please see newly added sheet reference notes 3/AS1.0 and 28/AS1.1 for clarity as to the area of sidewalk to be restored
for the sidewalk underdrain.
d) Please see document named “619 Grove – Pump Verification Calculation” for the value guidelines for installation. Please
also see newly added spec sheets 1/AS1.2 for pump details.
7. Comment: 7. Revise Plans as follows:
a. For Grove Street, note or dimension the 70’ right-of-way width on the site plan. Show the 35’ dimension of the centerline to
property line, 23’ centerline to face of curb, and 12’ from face of curb to property line dimensions for reference.
b. Show existing utility on all sheets with a line, not just a callout.
c. Clearly show the drive approach and driveway on the plans.
d. There are abbreviations used that are not included in the legend
e. A Complete site demolition plan for reference. Show all existing and proposed site improvements, plantings, and utilities to
remain and to be removed
f. Based on Google Earth there is a utility box located on the south side of the drive approach. Please verify
g. The plans call for the driveway to remain, but site plan sheet shows installation of 2” Schedule 40 PVC Drain pipe along the
drive. Please clarify the approach for installation.
h. Show the material of the existing utility. See the attached Utility grid maps for reference.
i. Confirm Parcel 1 water meter is shown in the correct location, The approved building plans for parcel 1 shows it closer to the
drive approach
Response:
a) Dimensions have been added to the site plan, per comment.
b) Please refer to sheet legend on sheet AS1.1 for utility lines.

c) Driveway approach and driveway have been shown on the site plan by a paver hatch. Sheet note 5 also indicates the
location of this driveway.
d) Please refer to the survey legend on sheet SV1.1. Please also refer to newly added “abbreviations” section on sheet AS1.1
for the few abbreviations that are not included in the survey legend.
e) Please see new sheet AS1.0 for site demolition notes. Everything is to remain other than the portion of the driveway to be
removed to input new utility lines.
f) The Utility box pictured in google earth is not for this property. Please refer to the survey on sheet SV1.1 as there is no
utility present.
g) Note 5/AS1.1 has been revised to read “Existing driveway and flatwork. Portion to be removed for utilities is shown on
sheet AS1.0”. Please refer to sheet AS1.0 for area to be removed.
h) Utility materials have been added to the site plan, per comment.
i) Sheet reference note 26/AS1.1 has been added to call out the existing water meter for the ADU at parcel 1.
8. Comment: 8. The Utilities department will be added to the next round of review you can expect possible comments from them in
regard to the new ADU Lateral connecting to Parcel 1 sewer lateral.
Response: Understood.
Planning v.1 Ethan Estrada ejestrad@slocity.org 8057817576
9. Comment: For process tracking purposes, this correction will remain until all other corrections provided for this permit application
have been resolved.
Response: Understood.
10. Comment: Trees appear to possibly be impacted by your project proposal and will require review by the City Arborist. An arborist
report may be required.
Response: Understood.
11. Comment: Provide expanded calculations/confirm the existing lot coverage for this property on the title sheet.
Response: Prior lot split, the previous parcel was 6,000 S.F. Please see sheet SV1.1 for split parcels. The current split parcel the
ADU resides on is a 3,589 S.F. lot. Therefore, the calculations of lot coverage has been revised to include the existing primary
residence footprint only, as we are proposing an ADU that is excluded from lot coverage calculations. Per SLOMC § 17.70.120(B)(5).
12. Comment: Title sheet states one parking space is provided in the driveway. On the site plan, note the location and dimensions of
this parking space - keep in mind that parking may not be located in the front yard setback.
Response: Parking space along with it’s width has been shown in the existing driveway, not in the front yard setbacks, per comment.
13. Comment: The MEP plan depicts a condenser on the north side of the proposed addition, but the site plan and elevations do not
depict this mechanical equipment. Ensure this equipment is depicted consistently throughout the plan set - note the distance
between the condenser and the north property line on the site plan.
Response: Condenser has been added to all applicable drawings to keep consistency throughout the plans. Dimensions between
the condenser and the north property line has also been added per comment.
14. Comment: Per SLOMC 17.70.080, the height of structures on properties with an average cross-parcel slope less than 16% shall
be measured from the average natural grade of the portion of the parcel that the proposed structure is to be built on. Adjust the
height measurements provided on the elevations so that they are measured from average natural grade.

15. Comment: On the elevations, note the direction from which the elevations are being viewed from.
Response: Elevation labels have been updated to include the direction in which they are viewed from, per comment.
16. Comment: MEP plan indicates that there will be exterior lighting. Ensure that such lighting is also depicted in the elevations.
Response: Please see updated drawing 4/A3.2. Exterior lighting has been added to said drawing and called out using reference note
11/A3.2.
17. Comment: Per SLOMC 17.70.100(B), provide manufacturer’s catalog cuts and drawings of all proposed exterior lighting to confirm
compliance with SLOMC 17.70.100 as required in SLOMC 17.69.040(E).
Response: Please see sheet reference note 1/MEP1 and new note g in the general lighting notes for compliance with SLOMC
17.70.100. All lighting will be night sky compliant, high efficiency, and shall be controlled by occupant sensors. The exact lighting
fixtures will be chosen by the property owner and will comply with these specifications.
18. Comment: Per SLOMC 17.70.100(B), provide a 10’ by 10’ grid of both the initial and maintained lighting levels of all proposed
exterior lighting onsite, including impact on adjacent properties, to confirm compliance with SLOMC 17.70.100 as required in
SLOMC 17.69.040(E).
Response: Per response to the above comment, please see sheet reference note 1/MEP1 and new note g in the general lighting
notes for compliance with SLOMC 17.70.100. All lighting will be night sky compliant, high efficiency, and shall be controlled by
occupant sensors. The exact lighting fixtures will be chosen by the property owner, and will comply with these specifications
Fees v.1 Vanessa Nichols vnichols@slocity.org 8057817588
19. Comment: #1 CODE-000350-2024 remains unresolved. Plans shall be approved to resolve that code case prior to additional
permits being approved. Please submit an application to resolve.

below in half-tone for reference, and responses are provided in red font:
California Code Check – Building Review 2022 CBC Comments
Wastewater Offset v.2 Nico Gurney
1. Comment: Pursuant to SLOMC 13.08.396, development located within a designated capacity constrained basin that results in
intensified wastewater flow is required to offset the projected increase in wastewater discharge. Intensified development includes,
but is not limited to, an increase in residential units or density, an increase of 450 square feet or more of habitable residential or
nonresidential floor area (excluding garages and accessory structures without plumbing fixtures), or an increase in plumbing fixture
units of 10 percent or more above existing conditions. The proposed project appears to meet one or more of these thresholds
within a capacity constrained basin and is therefore subject to the Wastewater Flow Offset Program.
Prior to issuance of a building permit, demonstrate compliance with SLOMC 13.08.396. Submit a completed Wastewater Offset
Flow Application and provide current project plans identifying existing and proposed uses, existing and proposed habitable floor
area, existing and proposed plumbing fixture units, and any proposed sewer lateral modifications. If the applicant believes the
project does not constitute intensified development under SLOMC 13.08.396, provide a written calculation comparing existing and
proposed floor area, fixture units, and use demonstrating that no net increase in wastewater flow will occur. Building permit
issuance is contingent upon Utilities verification that wastewater flow offset requirements have been satisfied.
Response: Wastewater offset application has been added to the submittal, along with current project plans.

Utilities Project Manager (Building) v.2 Nico Gurney
2. Comment: Sheet AS1.0: Does sewer lateral from parcel one also feed the proposed sewer pump?
Response: No. The sewer lateral from parcel one is its own entity, and does not feed into the proposed sewer pump.
Public Works Permit Review v.2 Emma Laplante elaplant@slocity.org 8057817199
3. Comment: 1. Include the following note under Standard Public Works Notes
a. All surface and subsurface drainage systems designed at less than 2% shall have final gradients certified by a licensed surveyor
or engineer prior to final inspection approvals.
Response: Please see comment i under “Standard Public Work Notes” on sheet T1.0 for above language.
4. Comment: 2. These plans are considered incomplete and additional comments may apply when all minimum plan information
and/or supporting documentation is provided through the plan review process.
Response: Understood.
5. Comment: 6. Clarify the Proposed drainage strategy
a. If physical obstructions or lot lines prohibit 10 feet of horizontal distance, 5% slope shall be provided to an approved alternative
method of diverting water away from the foundation. Swales used for this purpose shall be sloped a minimum of 2% along the
flowline. Resolved
b. Revise the invert elevations to provide a minimum 2% gradient if practical. As an alternative, the gradients may be reduced to
not less than 1% when verified by a licensed surveyor or engineer. This is including the outlet pipe to the street. Comment
Remain: Water shall not be pumped into the street. Invert/location needs to be revised to allow for gravity flow into the street.
c. Show limits of sidewalk restoration from score mark to score mark for this sidewalk underdrain. Resolved
d. Provide details and calculations for hydrologic assessment and sump pump capacity. The proposed engineered drainage system
will require the engineer of record to certify the system is built in conformance with the system design and approved plans prior to
final inspection. Resolved
Response:
a) Resolved.
b) Invert elevation has been updated to show gravity flow from the catch basin to the street. Please see new detail 4/AS1.2
for further clarity.
c) Resolved.
d) Resolved.
6. Comment: 7. Revise Plans as follows:
a. For Grove Street, note or dimension the 70’ right-of-way width on the site plan. Show the 35’ dimension of the centerline to
property line, 23’ centerline to face of curb, and 12’ from face of curb to property line dimensions for reference. Resolved
b. Show existing utility on all sheets with a line, not just a callout.
c. Clearly show the drive approach and driveway on the plans. Comment Remains: Through additional research it seems like the
drive approach is being converted to curb under BLDG-1030-2023/ENCR-0189-2026. In addition is also appears that the Majority
of the driveway will be replace with concrete under the same permit. Please revise the plans to reflect the changes under the
above listed permit.
d. There are abbreviations used that are not included in the legend. Resolved
e. A Complete site demolition plan for reference. Show all existing and proposed site improvements, plantings, and utilities to
remain and to be removed. Comment remains: TOPO shows brick pavers where the ADU is going but there are no call outs to

remove them. Please clarify
f. Based on Google Earth there is a utility box located on the south side of the drive approach. Please verify
g. The plans call for the driveway to remain, but site plan sheet shows installation of 2” Schedule 40 PVC Drain pipe along the
drive. Please clarify the approach for installation. Comment remain: plans need to reflect the improvement outline in BLDG-1030-
2023/ENCR-0189-2026
h. Show the material of the existing utility. See the attached Utility grid maps for reference. Resolved
i. Confirm Parcel 1 water meter is shown in the correct location, The approved building plans for parcel 1 shows it closer to the
drive approach. Resolved
Response:
a) Resolved.
b) Existing utility on plans are represented with both a line and a callout. Sizes for street utility are also provided on drawing
1/AS1.1. Please refer to the symbol legend on sheet AS1.1 for clarity as to which line represents which utility.
c) It appears that the driveway approach was not converted to concrete per the previous plan set. The google earth image
from September 2025 still shows pavers at the driveway approach. Notes 4/AS1.0 and 32/AS1.1 now call out this diveway
approach to be converted to concrete.
d) Resolved.
e) Please refer to newly added sheet reference note 1/ SV1.1 for clarity as to brick pavers being removed.
f) Utility box has been drawn in on drawing 1/AS1.1. Please see sheet reference note 30/AS1.1.
g) Plans have been updated to reflect the removal and replacement of pavers to install the piping leading up to the street.
Please refer to notes 1/AS1.0 and 5/AS1.1 for further clarity.
h) Resolved.
i) Resolved.
7. Comment: 8. The Utilities department will be added to the next round of review you can expect possible comments from them in
regard to the new ADU Lateral connecting to Parcel 1 sewer lateral. Resolved: See utility comments
Response: Understood.
8. Comment: 9. Additional Plan Comments
a. There is a discrepancy in the property line between the approved build plans for Parcel 1 (back parcel) and current plans for
Parcel 2. Provide verification from the survey on which property line location is correct.
Response: The property line on the previous plan set appears to be incorrect. The survey on sheet SV1.1, completed on July 30th,
2024, is the most up to date drawing and shows an accurate representation of the existing site conditions. Please refer to our
drawing set for the correct site conditions.
Fees v.2 Vanessa Nichols vnichols@slocity.org 8057817588
9. Comment: #1 CODE-000350-2024 remains unresolved. Plans shall be approved to resolve that code case prior to additional
permits being approved. Please submit an application to resolve.
Response: This shall be resolved prior to permit issuance. John Rourke (The property owner) has been in conversation with
community development staff on resolution of this item. Final determination on how to proceed is pending and will be provided once
it is available.
10. Comment: #2 Please provide a plumbing calculation to verify that the existing water meter and water service will be sufficient to
service both the existing residence and the new ADU. PARTIAL COMMENT REMAINS: Plumbing calc needs to reflect the upgrade
of water meter and service. Sheet Reference Note #9. Sheet S1.1, needs to be update to reflect the water meter being upgraded.

Arborist v.2 Walter Gault wgault@slocity.org 8057817578
14. Comment: Per Uniform Design Criteria 1010 3.1.23 Street Trees, a minimum of one street tree shall be installed per 35 feet of
street frontage for any commercial or residential building permit addition or new dwelling unit, unless City Arborist determines that
the site cannot accommodate a new tree. Street trees may be grouped if necessary to avoid conflict with other improvements.
Please select a street tree from the City Approved Tree List (Zone 1 tree species), and if in a Fire Hazard Severity Zone, the City of
SLO Zone 1 Defensible Space Tree List. Street trees may be planted in front yards to satisfy the requirement.
Corrective Action: Please provide a landscaping plan that satisfies the Uniform Design Criteria 1010 3.1.23 Street Trees
requirement. Plan shall include tree species selected from Engineering Standard (8010) and Zone 1 category, tree size, location,
City Engineering Standards for Tree Planting (8210, 8220, 8250) and an irrigation detail (8670 Tree Bubbler or 8660 Drip
Irrigation).
Response: Please see “Compensatory Replanting Tree Schedule” for information as to the species, size and irrigation method for
the new tree. Kindly also refer to note 31/AS1.1 for location of said tree.
15. Comment: If a tree protection and monitoring plan is necessary or a tree removal application and compensatory replanting plan is
required, please provide a project arborist to oversee all arboriculture activities.
Corrective Action: Please provide a tree protection plan on demo, grading and building permit plan submittals that satisfies
Specification 77-1.03A(2) and identifies the location, type, trunk and canopy diameter of all trees onsite (and adjacent offsite) and
explains the likelihood of tree retention (based on impact to the critical root zone of trees on- and offsite). An Arborist Report
providing further information may be required.
Response: There are no trees impacted by the proposed ADU, and therefore an arborist report will not be required for this project.
Planning v.2 Ethan Estrada ejestrad@slocity.org 8057817576

compliance with SLOMC 17.70.100 as required in SLOMC 17.69.040(E).
Response: Please see spec sheet C/MEP2 for lighting specs. Owner shall choose fixtures that are or are equal to said lighting fixture
to maintain compliance with SLOMC 17.70.100.
18. Comment: Per SLOMC 17.70.100(B), provide a 10’ by 10’ grid of both the initial and maintained lighting levels of all proposed
exterior lighting onsite, including impact on adjacent properties, to confirm compliance with SLOMC 17.70.100 as required in
SLOMC 17.69.040(E).
Response: Please see newly added sheet MEP2 for exterior lighting compliance. Drawings A /MEP2 and B/MEP2 show lighting
values around and at the property line to be in compliance with SLOMC 17.70.100.
19. Comment: Upon further review, it's been noted that the site plan shows what appears to be another condenser on the south side
of the proposed ADU that encroaches into the existing easement. This equipment is not shown on any other sheet in the plan set.
Is this condenser supposed to be a part of this project? If it is, it will need to be relocated out of the existing easement.
Response: Thank you for catching this. Said condenser has been removed. The condenser location is now correctly shown to be
along the northern building face.

below in half-tone for reference, and responses are provided in red font:
California Code Check – Building Review 2022 CBC Comments
Wastewater Offset v.2 Nico Gurney
1. Comment: Sheet AS1.1 - Correct sheet reference note 19 and 25 to reflect sewer pump configuration.
Response: Sheet reference notes 19 and 25 have been updated accordingly. Notes now correctly reflect the sewer pump
configuration.
2. Comment: Sheet AS1.1 - Modify note 16 to include replacement of onsite lateral.
Response: Sheet reference note 16/AS1.1 has been updated to reflect the sewer lateral to be replaced. Note now reads, “existing
sewer lateral to be replaced”.

Response: This shall be resolved prior to permit issuance. John Rourke (The property owner) has been in conversation with
community development staff on resolution of this item. Final determination on how to proceed is pending and will be provided once
it is available.
4. Comment: #3 Final fees pending response to comments and other department reviews.
Response: Understood.
Planning v.2 Ethan Estrada ejestrad@slocity.org 8057817576
5. Comment: For process tracking purposes, this correction will remain until all other corrections provided for this permit application
have been resolved.
Response: Understood.
6. Comment: Upon further review, it's been noted that the site plan shows what appears to be another condenser on the south side
of the proposed ADU that encroaches into the existing easement. This equipment is not shown on any other sheet in the plan set.
Is this condenser supposed to be a part of this project? If it is, it will need to be relocated out of the existing easement. Post 2nd
Submittal - this condenser is still shown on the site plan in the most recent submittal.
Response: Thank you for catching this. Said condenser has been removed. The condenser location is now correctly shown to be
along the northern building face.

I certify that, in the performance of the work for which this permit is issued, I shall not employ any person in any manner so as to become subject to the

APPLICATION FOR WAIVER OF SOILS TEST FOR MINOR ADDITIONS
TO ONE AND TWO-FAMILY DWELLING UNITS
GENERAL INFORMATION:
Project Address: ___________________________________Application #: _________________
Applicant Name: _____________________________________Phone #: ________________
BACKGROUND: Historically, quantifiable data has been created using accepted soil science
methodologies by approved agencies using approved methods indicating that, in general, the soil
conditions likely to be encountered throughout the City of San Luis Obispo would consist of expansive,
compressible, shifting or other questionable soil characteristics. These types of soil conditions would
require a complete geotechnical evaluation for moderate and major projects.
PURPOSE: In order to help alleviate the burdens of time and disproportionately high cost associated
with obtaining a soil test for minor residential additions up to 500 square feet to one and two family
dwellings, the City of San Luis Obispo Building Division has developed a policy allowing a waiver of the
soil test as specified in the California Residential Code Section R401.4.
POLICY STATEMENT: Where a soils test has not been previously provided in accordance with the
2022 CRC Section R401.4; one and two family dwelling unit residential additions of 500 square feet or
less, up to two stories (addition footprint area), may forego a soils test provided the applicant agrees to the
following checked statements by signing and dating this application in the appropriate location at the
bottom of this application:
An on-site investigation has revealed no foundation failure of the existing residence.
The type of construction proposed meets or exceeds the minimum provisions for wall and
roof-ceiling construction in accordance with the 2022 CRC Chapters 6 and 8.
The foundation system proposed meets or exceeds the minimum requirements in accordance
with the 2019 City of San Luis Obispo Construction and Fire Code Amendments Table
1809.7.
A minimum allowable soil bearing pressure of 1500 PSF has been utilized for the design of
foundation systems as shown in the 2022 CRC Table R401.4.1.
The proposed area of work on the site does not exceed a maximum 20% slope.

PURPOSE: This plan can only be used for minor building projects (SFR - new, remodels, additions; and/or commercial remodels).
Newly constructed commercial buildings under 2019 CalGreen Codes require the development and implementation
of a WPCP similar to the standards of a State submitted SWPPP. This plan is only to serve as a guide, if the
applicant elects to use it. The BMPS specified herein shall be considered just the “Minimum BMPs” and during the
course of the project additional BMPs (Necessary BMPs) may be required to protect water quality. Please note that
an in-fill new single family home project may require additional plan elements. This plan shall be used in accordance with
CGP 2009-0009-DWQ, City Stormwater Permit & 2019 CalGreen Building Codes.

Subject: Incomplete Letter #4: SBDV-0458-2022 (619 Grove): [Proposed minor
subdivision under Senate Bill 9 at 619 Grove Street]
Dear Mr. Rourke:
Thank you for the April 13, 2023, submittal for the 619 Grove Street minor subdivision project.
We have reviewed your application and found it to be incomplete. We will be unable to
process your application until additional information and/or revisions have been submitted
to the satisfaction of the Community Development Director. Preliminary review is necessary
to ensure that staff has adequate information to evaluate your project and identify any
conflicts with City standards or guidelines. The purpose of this letter is to provide you with
a list of items that need to be addressed prior to taking action on your project.
Preliminary review indicates that your application will remain in an incomplete status
until the following information and/or revisions are submitted:
Note: Upon resubmittal please provide a narrative indicating where responses to these items
can be found on plans.
Department comments/completeness items:
Planning Division - Community Development Department
1. Government Code Section 66411.7(c) states that the Urban Lot Split shall comply
with all applicable objective subdivision standards. The proposed lot split shall
comply with all objective standards identified in Municipal Code Section 16.18
(including Lot Frontage requirements). Parcel 1 has been proposed as a land
locked parcel and is not in compliance with objective standards. In accordance
with Gov Code 66411.7(e)(2) the parcel is required to adjoin the public right-of-

way.
a. Revise plans to show compliant access to public right-of-way.
Comment Remains. Comment Remains. Understood that the
project proposal contains access to public right of way via access
easement. Please refer to comment 8 to provide an accessway that
complies with the objective subdivision standards. Substandard
accessways shall only be approved by the Public Works Director.
2. If access to both lots is to be shared, please identify the location of the required
parking space for the existing residence, that does not interfere with the
accessway required for the newly created lot. Comment Remains. Comment
Remains. Please refer to engineering comments to provide compliant
parking or remove parking from your proposal.
3. Please identify all setbacks for the existing structures to all property lines. Setbacks
shall be provided with a minimum distance of five-feet from any existing structures
inclusive of the newly created property line (a four-foot setback may be available in limited
circumstances where building and fire codes can be met). OK.
4. If a shared driveway is proposed, an agreement shall be recorded to reflect ownership of
the accessway for Parcel 1. OK.
5. Please provide signatures from all affected parties on the preliminary title report
consenting to the subdivision. OK.
6. Please provide two copies of the drainage study or explaining the drainage area tributary
to the subdivision and a statement setting forth in detail the manner in which storm water
runoff will enter the subdivision are required. OK.
7. Provide a statement of proposed improvements and landscape modifications that are
necessary to satisfy parking requirements and the accessway to Parcel 1. OK.
8. Demonstrate compliance with applicable standards of Table 3 in 16.18.030 except for
requirements that would physically preclude the development of an 800 square foot
dwelling unit. Comment Remains. Please provide a statement stating how the project
cannot satisfy applicable standards. Please specifically identify the objective
standard that physically precludes the project from providing a 20’ access easement
or access way and why the project is unable to comply. The proposed exception is
only required because there are no feasible design options which could allow for site
development of two minimum 800 square foot units on either of the two resulting
parcels. For the purpose of this finding, existing improvements or development is not
considered a physical constraint. Comment Remains, in accordance with Senate Bill 9,
Section 2, 3. D., the parcel being subdivided shall not result in any alterations of the
existing residence (that was rented out in the last 3 years), if the substandard accessway
results in an adverse impact as determined by the Engineering Division or Fire Marshal,
then the proposed parcel map shall not qualify under SB 9.
9. If the project is proposed as a Flag Lot Subdivision demonstrate compliance with all
objective standards identified in Section 16.18.060. Understood that this is not a Flag
Lot Subdivision.
10. If the project is proposed as a Common Interest Subdivision demonstrate compliance with
SBDV-0458-2022– Completeness Review #4

all application requirements and objective standards identified in Chapter 16.17.
Understood that this is not a Common Interest Subdivision.
Additional Comments – These comments are not completeness comments but may directly affect the
staff recommendation. Please review the Subdivision Regulations Chapter 16.18 (General
Subdivision Design Standards) and revise plans as appropriate.
• Section 16.18.030 (Lot Dimensions), the lot does not satisfy lot frontage requirements.
Comment remains as a note.
• Per Engineering Code #2120, the existing driveway does not meet objective standards for
required dimensions of the driveway that is intended to provide access to the newly created lot
(10 feet). Comment remains as a note.
• The Urban Lot Split application does not appear eligible under Gov. Code 66511.7, because the
project does not comply with Gov. Code 66511.7(c) and is inconsistent with the objective
standards of the Subdivision Regulations Chapter 16.18 for lot frontage requirements, as
described above. Comment remains as a note.

comply with Section 66411.7.e.3 to the satisfaction of the Planning department.
Comment remains.
4th Review: Provide justification for how proposed parking spot can be

at least 5 feet from the new property line, sprinklered buildings may be no closer than
3 feet, although SB9 would increase that to a minimum of 4 feet. OK.
24. Provide legal fire department access from the public way to the newly created

from any new buildings on the created parcel shall have unobstructed access to
the public way. The Fire Marshal has significant safety concerns regarding
the occupants of the land-locked parcel being able to safely egress to the
public way considering the tight passage along the existing residence on a
parcel the occupants of the rear property have no control over, does not have
fire sprinklers and heat exposure from a structure fire would pose an

show a 6-foot-wide access, utility and driveway easement on the parcel 2 south
property line in favor of parcel 1. As both an access easement and driveway
easement it will be rendered unusable for egress from the residence on parcel 1
should a vehicle use the driveway for parking. In addition, it appears that the path
of egress from the residence on parcel 1 accesses the public way through the north
side of the residence on parcel 2. There is no indicated egress easement shown
that would make this legal.

a. Revise plans to show compliant access to public right-of-way.
Understood that the project proposal contains access to public
right of way via access easement. Please refer to comment 8 to
provide an accessway that complies with the objective subdivision
standards. Substandard accessways shall only be approved by the
Public Works Director.
2. If access to both lots is to be shared, please identify the location of the required
parking space for the existing residence, that does not interfere with the
accessway required for the newly created lot. Comment Remains. Please refer
to engineering comments to provide compliant parking.
3. Please identify all setbacks for the existing structures to all property lines. Setbacks

dwelling unit. Comment Remains. Please provide a statement stating how the project
cannot satisfy applicable standards. Please specifically identify the objective
standard that physically precludes the project from providing a 20’ access easement
or access way and why the project is unable to comply. The proposed exception is
only required because there are no feasible design options which could allow for site
development of two minimum 800 square foot units on either of the two resulting
parcels. For the purpose of this finding, existing improvements or development is not
considered a physical constraint.
9. If the project is proposed as a Flag Lot Subdivision demonstrate compliance with all
objective standards identified in Section 16.18.060. Understood that this is not a Flag
Lot Subdivision.

Department comments/completeness items:
Planning Division - Community Development Department
1. Government Code Section 66411.7(c) states that the Urban Lot Split shall comply
with all applicable objective subdivision standards. The proposed lot split shall
comply with all objective standards identified in Municipal Code Section 16.18
(including Lot Frontage requirements). Parcel 1 has been proposed as a land
locked parcel and is not in compliance with objective standards. In accordance
with Gov Code 66411.7(e)(2) the parcel is required to adjoin the public right-of-

way.
a. Revise plans to show compliant access to public right-of-way.
Comment Remains. Comment Remains. Understood that the
project proposal contains access to public right of way via access
easement. Please refer to comment 8 to provide an accessway that
complies with the objective subdivision standards. Substandard
accessways shall only be approved by the Public Works Director.
2. If access to both lots is to be shared, please identify the location of the required
parking space for the existing residence, that does not interfere with the
accessway required for the newly created lot. Comment Remains. Comment
Remains. Please refer to engineering comments to provide compliant
parking or remove parking from your proposal. OK.
3. Please identify all setbacks for the existing structures to all property lines. Setbacks
shall be provided with a minimum distance of five-feet from any existing structures
inclusive of the newly created property line (a four-foot setback may be available in limited
circumstances where building and fire codes can be met). OK.
4. If a shared driveway is proposed, an agreement shall be recorded to reflect ownership of
the accessway for Parcel 1. OK.
5. Please provide signatures from all affected parties on the preliminary title report
consenting to the subdivision. OK.
6. Please provide two copies of the drainage study or explaining the drainage area tributary
to the subdivision and a statement setting forth in detail the manner in which storm water
runoff will enter the subdivision are required. OK.
7. Provide a statement of proposed improvements and landscape modifications that are
necessary to satisfy parking requirements and the accessway to Parcel 1. OK.
8. Demonstrate compliance with applicable standards of Table 3 in 16.18.030 except for
requirements that would physically preclude the development of an 800 square foot
dwelling unit. Comment Remains. Please provide a statement stating how the project
cannot satisfy applicable standards. Please specifically identify the objective
standard that physically precludes the project from providing a 20’ access easement
or access way and why the project is unable to comply. The proposed exception is
only required because there are no feasible design options which could allow for site
development of two minimum 800 square foot units on either of the two resulting
parcels. For the purpose of this finding, existing improvements or development is not
considered a physical constraint. Comment Remains, in accordance with Senate Bill 9,
Section 2, 3. D., the parcel being subdivided shall not result in any alterations of the
existing residence (that was rented out in the last 3 years), if the substandard accessway
results in an adverse impact as determined by the Engineering Division or Fire Marshal,
then the proposed parcel map shall not qualify under SB 9. OK.
9. If the project is proposed as a Flag Lot Subdivision demonstrate compliance with all
objective standards identified in Section 16.18.060. Understood that this is not a Flag
Lot Subdivision.
10. If the project is proposed as a Common Interest Subdivision demonstrate compliance with
SBDV-0458-2022– Completeness Review #5
10/17/2023
Page 3
all application requirements and objective standards identified in Chapter 16.17.
Understood that this is not a Common Interest Subdivision.
11. New Comment. Per Municipal Code 16.15.020 I. 2., draft easement agreements shall be
submitted with the subdivision application. Please provide the draft easement agreements
to be recorded on both parcels.
12. New Comment. Please complete updated owner occupancy affidavit.
Additional Comments – These comments are not completeness comments but may directly affect the
staff recommendation. Please review the Subdivision Regulations Chapter 16.18 (General
Subdivision Design Standards) and revise plans as appropriate.
• Section 16.18.030 (Lot Dimensions), the lot does not satisfy lot frontage requirements.
Comment remains as a note. Please contact planning staff regarding a request to
this exception. Exceptions must meet the findings under Section 16.15.030
Exceptions to objective standards.
• Per Engineering Code #2120, the existing driveway does not meet objective standards for
required dimensions of the driveway that is intended to provide access to the newly created lot
(10 feet). Comment remains as a note.
• The Urban Lot Split application does not appear eligible under Gov. Code 66511.7, because the
project does not comply with Gov. Code 66511.7(c) and is inconsistent with the objective
standards of the Subdivision Regulations Chapter 16.18 for lot frontage requirements, as
described above. Comment remains as a note.

16. Provide any shared easements for parking, access, driveway, structural integrity
(retaining wall, etc), drainage (blanket drainage easement appears to have parcel
numbers reversed), irrigation, etc. Comment remains.
4th Review: Blanket drainage easement parcel numbers still shown as
reversed. Comment remains. Please contact engineering prior to
resubmittal to confirm corrections. Easement was not corrected it was just
removed. OK.
17. Provide plan for off-street parking and right of way approaches of both units to
comply with Section 66411.7.e.3 to the satisfaction of the Planning department.
Comment remains.
4th Review: Provide justification for how proposed parking spot can be
accessed from approach. As shown, it is unclear how vehicles can access this
spot (turning radius, etc.). Demonstrate compliance with the City’s parking
and driveway standards. Comment remains. Remove parking space if you are
pursuing car share or provide details for vehicle maneuverability in accordance
with the City’s parking and driveway standards for how the proposed parking
spot can be accessed from approach. OK.
18. Feasibility study checklist has some portions incomplete and questions unanswered.
Please complete. OK

26. Provide legal fire department access from the public way to the newly created
parcel. Building address numbers shall be visible from the public way. Egress
from any new buildings on the created parcel shall have unobstructed access to
the public way. The Fire Marshal has significant safety concerns regarding
the occupants of the land-locked parcel being able to safely egress to the
public way considering the tight passage along the existing residence on a
parcel the occupants of the rear property have no control over, does not have
fire sprinklers and heat exposure from a structure fire would pose an
eminent risk to those escaping to the public way and a reasonable size area of
refuge is non-existent. For safety reasons, the fire department can’t support
the application as submitted unless the applicant provides a map that
conforms to the City’s lot frontage requirements that provides both egress
and fire department access to the rear parcel. Comment Remains. [California
Residential Code 311.1 Means of Egress, California Fire Code 1028.5 Access
to a Public Way, California Fire Code 504.1] Comment Remains. The plans
show a 6-foot-wide access, utility and driveway easement on the parcel 2 south
property line in favor of parcel 1. As both an access easement and driveway
easement it will be rendered unusable for egress from the residence on parcel 1
should a vehicle use the driveway for parking. In addition, it appears that the path
of egress from the residence on parcel 1 accesses the public way through the north
side of the residence on parcel 2. There is no indicated egress easement shown
that would make this legal. OK.

SUBJECT: SBDV-0458-2022 – Conformity Review (619 Grove Street, San Luis Obispo CA,
93401)
Dear John Rourke:
On October 17, 2023, I reviewed your request to pursue a subdivision of a 6,000 square foot R-1
lot as allowed under Senate Bill 9 for conformance with applicable City standards. The proposed
subdivision is consistent with applicable City standards but does not meet the required Lot
dimensions of Municipal Code Chapter 16.18.030 Table 3. It is identified that under Senate Bill
9, this objective standard (Table 3. Minimum Lot Area and Dimensions) would physically preclude
the subdivision from being processed and therefore will not be required. It has also been identified
that this lot does not satisfy lot frontage requirements under 16.18.030 Table 3, but a justification
statement has been provided stating that a vehicle access easement is not required due to the car
share agreement provided and that the subdivision will provide a 10-foot pedestrian access
easement as required under Municipal Code Section 16.15.025 B. 2. Prior to final map recordation
the applicant will submit a car share agreement for recordation on the property in-lieu of providing
any required on-site vehicle parking spaces. It has been determined that the proposed subdivision
is eligible for the lot split under Government Code Section 66411.7 and Senate Bill 9 based on the
findings below. An application for a Parcel Map can now be submitted to the Engineering Division.
1. The subject property is zoned R-1.
2. The proposed project is not located within areas defined in subparagraphs (B) to (K),
inclusive, of paragraph (6) of subdivision (a) of California Government Code §65913.4,
which includes:
a. Very High Fire Hazard Severity Zone
b. Earthquake Fault Zone
c. Special Flood Hazard Area
d. Regulatory Floodway
3. The subject property is not located within a historic district, identified in the State Historic
Resources Inventory, or designated by the City as a historic resource.
4. The proposed project will not require the demolition, or alteration, of any of the following:
a. Housing restricted for moderate, low, or very-low income households.
SBDV-0528-2022
247 Warren Way
Page 2
b. Housing subject to rent or price control
c. Housing that was withdrawn from the rental market in the last 15 years (per Section
12.75 of Division 7 of Title 1 of the Government Code)
d. Housing occupied by a tenant in the last three (3) years.
5. Properties that contained a rental unit within the last three (3) years, will not demolish 25%
or more of the existing exterior structural walls.
6. The proposed project will not be rented for periods of less than thirty (30) consecutive days
at a time.
7. The project will provide at least one (1) off-street parking space per unit or complete a car
share agreement to qualify for a parking exception.
8. The lot split will result in no more than two (2) lots of at least 1,200 square feet per lot.
9. The resulting lots will be at least 40% of the size of the existing lot.
10. The property has not previously been split through an SB9 Urban Lot Split.
11. The resulting lot split will contain two (2) housing units or less, on each property, including
ADUs or JADUs.
12. The individual property owner will occupy one of the housing units as a result of the lot
split as their primary residence for a minimum of three (3) years after the approval date.
13. Applicant has read, signed, and submitted the 3-year owner occupancy affidavit.
14. The urban lot split conforms to all objective standards of the Subdivision Map Act.
If you have any questions regarding this letter, or if you need additional information about
identified requirements, please contact Matt Lafreniere at mlafreni@slocity.org, or Owen Goode

Subject: Response to Incomplete Letter #1: SBDV-0458-2022 (619 Grove) Minor Subdivision
(MBS 22-187)
Dear Mr. Goode:
Following is our response to the incomplete letter for the above project. I have copied your
letter and will respond directly under each item in red type.
Department comments/completeness items:
Planning Division - Community Development Department
1. Government Code Section 66411.7(c) states that the Urban Lot Split shall comply
with all applicable objective subdivision standards. The proposed lot split shall comply with all
objective standards identified in Municipal Code Section 16.18 (including Lot Frontage
requirements). Parcel 1 has been proposed as a land locked parcel and is not in
compliance with objective standards. In accordance with Gov Code 66411.7(e)(2) the parcel
is required to adjoin the public right-of-way.
This is a misquote and a misinterpretation of Section 66411.7(c) which it says:
“Except as provided in paragraph (2), notwithstanding any local law, a local agency
may impose objective zoning standards, objective subdivision standards, and
objective design review standards applicable to a parcel created by an urban lot split
that do not conflict with this section.(2) A local agency shall not impose objective
zoning standards, objective subdivision standards, and objective design review
standards that would have the effect of physically precluding the construction of two
units on either of the resulting parcels or that would result in a unit size of less than
800 square feet.”
It does not say “shall comply” it says you “may impose”. But it also says you shall not impose
objective standards that physically preclude construction of 2 units on either parcel.
2 of 6
Imposing a flag driveway with a minimum 20 foot width would preclude the ability to
construct 2 units on either parcel.
SB9 also states:
(e) In addition to any conditions established in accordance with this section, a local
agency may require any of the following conditions when considering an application for
a parcel map for an urban lot split:
(1) Easements required for the provision of public services and facilities.
(2) A requirement that the parcels have access to, provide access to, or
adjoin the public right-of-way.
You may require one parcel to provide access to the other but you may not preclude the parcel
based on street frontage because it would preclude the construction of 2 units on either parcel.
2. If access to both lots is to be shared, please identify the location of the required
parking space for the existing residence, that does not interfere with the accessway
required for the newly created lot.
Parking will be directly behind the existing home. Garage will be removed to provide access to
rear parcel.
3. Please identify all setbacks for the existing structures to all property lines. Setbacks
shall be provided with a minimum distance of five-feet from any existing structures inclusive
of the newly created property line (a four-foot setback may be available in limited circumstances
where building and fire codes can be met).
SB 9 Section 66411.7(c)(3)(A) does not require setbacks for an existing structure or a structure
constructed in the same location and to the same dimensions as an existing structure. So
setbacks are not required here.
4. If a shared driveway is proposed, an agreement shall be recorded to reflect
ownership of the accessway for Parcel 1.
Easements shall be recorded with the final map.
5. Please provide signatures from all affected parties on the preliminary title report
consenting to the subdivision.
Please be specific, which signatures are missing? Who’s signature are we missing?
6. Please provide two copies of the drainage study or explaining the drainage area
tributary to the subdivision and a statement setting forth in detail the manner in which storm
water runoff will enter the subdivision are required.
Please provide the code that says a drainage study is required for an urban lot split. I’m
3 of 6
assuming there can be an easement for drainage.
7. Provide a statement of proposed improvements and landscape modifications that are
necessary to satisfy parking requirements and the accessway to Parcel 1.
Improvements and modifications will be proposed with future building plans.
8. Demonstrate compliance with applicable standards of Table 3 in 16.18.030 except for
requirements that would physically preclude the development of an 800 square foot dwelling
unit.
We cannot meet city standards because there is no way to provide a 20ft frontage for the back
parcel, luckily SB9 does not require street frontage, only access.
9. If the project is proposed as a Flag Lot Subdivision demonstrate compliance with all
objective standards identified in Section 16.18.060.
The project is not proposed as a flag lot subdivision.
10. If the project is proposed as a Common Interest Subdivision demonstrate compliance
with all application requirements and objective standards identified in Chapter 16.17.
SB9 allows for subdivision with access rather than frontage or common interest. For it to be
considered common interest the common area is owned either by the association or in common
by the owners of the separate interests who possess appurtenant rights to the beneficial use
and enjoyment of the common area. In this case there is not a common interest, just
easements in favor of the rear parcel.
Additional Comments – These comments are not completeness comments but may directly
affect the staff recommendation. Please review the Subdivision Regulations Chapter 16.18
(General Subdivision Design Standards) and revise plans as appropriate.
• Section 16.18.030 (Lot Dimensions), the lot does not satisfy lot frontage
requirements.
SB 9 does not require lot frontage.
• Per Engineering Code #2120, the existing driveway does not meet objective
standards for required dimensions of the driveway that is intended to provide access to the
newly created lot (10 feet).
•
SB 9 does not require lot frontage.
• The Urban Lot Split application does not appear eligible under Gov. Code 66511.7,
because the project does not comply with Gov. Code 66511.7(c) and is inconsistent with the
objective standards of the Subdivision Regulations Chapter 16.18 for lot frontage
requirements, as described above.
•
SB 9 does not require a flag lot or the 20 foot minimum lot frontage. SB 9 regulations control
4 of 6
over the City’s subdivision regulations for the design and development of this subdivision,
where the City’s regulations would preclude the development of 2 units with a minimum of 800
square feet on either parcel.
Engineering Division – Public Works/Community Development Department
11. Provide dimensions for site setbacks of existing buildings, and distance between

1. Government Code Section 66411.7(c) states that the Urban Lot Split shall comply
with all applicable objective subdivision standards. The proposed lot split shall comply
with all objective standards identified in Municipal Code Section 16.18 (including Lot
Frontage requirements). Parcel 1 has been proposed as a land locked parcel and is not
in compliance with objective standards. In accordance with Gov Code 66411.7(e)(2) the
parcel is required to adjoin the public right-of-way. a. Revise plans to show compliant
access to public right-of-way. Please clarify how the project will comply with the
access to public right of way requirements under Senate Bill 9. Comment
Remains.
Access to both lots will be from Grove Street. There is an existing out building that is
slated for removal in the future. An easement will be granted over proposed Parcel 2
to benefit proposed Parcel 1 (as shown on the tentative parcel map). The tentative
parcel map has been revised to show the proposed easement.
619 Grove Street 2 of 6
As designed, proposed Lot 1 is not landlocked. It will have a 6-foot access easement
and there will be a car share provided, per the SB 9 standards.
Other standards of the City’s municipal code will be met as follows:

2. If access to both lots is to be shared, please identify the location of the required
parking space for the existing residence, that does not interfere with the accessway
required for the newly created lot. Comment Remains.
Parking will be directly behind the existing home. See the revised tentative parcel map.
3. Please identify all setbacks for the existing structures to all property lines. Setbacks
shall be provided with a minimum distance of five-feet from any existing structures
inclusive of the newly created property line (a four-foot setback may be available in
limited circumstances where building and fire codes can be met). OK.
619 Grove Street 3 of 6
4. If a shared driveway is proposed, an agreement shall be recorded to reflect
ownership of the accessway for Parcel 1. OK.
5. Please provide signatures from all affected parties on the preliminary title report
consenting to the subdivision. OK.
6. Please provide two copies of the drainage study or explaining the drainage area
tributary to the subdivision and a statement setting forth in detail the manner in which
storm water runoff will enter the subdivision are required. OK.
7. Provide a statement of proposed improvements and landscape modifications that are
necessary to satisfy parking requirements and the accessway to Parcel 1. OK.
8. Demonstrate compliance with applicable standards of Table 3 in 16.18.030 except for
requirements that would physically preclude the development of an 800 square foot
dwelling unit. Comment Remains. Please provide a statement stating how the
project cannot satisfy applicable standards of Table 3.
See the table above under Item 1. Also see the example 800 square foot footprint on
proposed Parcel 1. The footprint shows consistency with the rear and side setback
requirements.
The requirement for a 10 or 20’ access to proposed Parcel 1, over proposed Parcel 2
cannot be met, but SB 9 requirements will be met with a 6-foot access easement and
there will be a car share provided for proposed Parcel 1.
9. If the project is proposed as a Flag Lot Subdivision demonstrate compliance with all
objective standards identified in Section 16.18.060. Comment Remains as a note
until access to the right of way is shown.
The project is not proposed as a flag lot subdivision.
The project is proposed as a shared access subdivision, with the accessway being 6 feet wide.
Please see the easement noted on the revised tentative map.
10. If the project is proposed as a Common Interest Subdivision demonstrate
compliance with all application requirements and objective standards identified in
Chapter 16.17. Comment Remains as a note until access to the right of way is
shown.
The project is not proposed as a Common Interest Subdivision. Access is shown on the
revised tentative parcel map as a 6’ wide access and utility easement.
Additional Comments – These comments are not completeness comments but may
directly affect the staff recommendation. Please review the Subdivision Regulations
Chapter 16.18 (General Subdivision Design Standards) and revise plans as appropriate.

• Section 16.18.030 (Lot Dimensions), the lot does not satisfy lot frontage requirements.
Comment remains as a note. SB 9 does not require a minimum lot frontage. The proposed
Parcel 1 will be provided access from the public street by way of an access easement, as shown
on the parcel map.
• Per Engineering Code #2120, the existing driveway does not meet objective
standards for required dimensions of the driveway that is intended to provide access to
the newly created lot (10 feet). Comment remains as a note.
The proposed project cannot meet a 10 foot wide driveway requirement. It will have a
6-foot access easement and there will be a car share provided, per the SB 9 standards.
• The Urban Lot Split application does not appear eligible under Gov. Code 66511.7,
because the project does not comply with Gov. Code 66511.7(c) and is inconsistent
with the objective standards of the Subdivision Regulations Chapter 16.18 for lot
frontage requirements, as described above. Comment remains as a note.
Gov. Code 66411.7(c) states:
(c) (1) Except as provided in paragraph (2), notwithstanding any local law, a
local agency may impose objective zoning standards, objective subdivision standards,
and objective design review standards applicable to a parcel created by an urban lot split
that do not conflict with this section. The objective standards cannot conflict.
(2) A local agency shall not impose objective zoning standards, objective
subdivision standards, and objective design review standards that would have the effect
of physically precluding the construction of two units on either of the resulting parcels or
that would result in a unit size of less than 800 square feet. A 20 foot wide road frontage
requirement would precluding the construction of any units on the proposed second parcel.
(3) (A) Notwithstanding paragraph (2), no setback shall be required for
an existing structure or a structure constructed in the same location and to the same
dimensions as an existing structure.
(B) Notwithstanding paragraph (2), in all other circumstances not
described in subparagraph (A), a local agency may require a setback of up to four feet
from the side and rear lot lines.
The proposed subdivision meets the requirements of Govt. Code 66411.7(c) because the
local agency cannot impose a condition, in this case the lot frontage requirement, when the
condition would preclude the development of an 800 square foot residence. Such a
condition would preclude any development on the proposed parcel.

parcel is required to adjoin the public right-of-way.
a. Revise plans to show compliant access to public right-of-way.
Understood that the project proposal contains access to public right of
way via access easement. Please refer to comment 8 to provide an
accessway that complies with the objective subdivision standards.
Substandard accessways shall only be approved by the Public Works
Director.
Car Share vehicle provided, no off street parking or access required.
2. If access to both lots is to be shared, please identify the location of the required
parking space for the existing residence, that does not interfere with the accessway
required for the newly created lot. Comment Remains. Please refer to
engineering comments to provide compliant parking.
Car Share vehicle provided, no off street parking or access required.
3. Please identify all setbacks for the existing structures to all property lines.
Setbacks shall be provided with a minimum distance of five-feet from any existing
2 of 6
structures inclusive of the newly created property line (a four-foot setback may be
available in limited circumstances where building and fire codes can be met). OK.
4. If a shared driveway is proposed, an agreement shall be recorded to reflect
ownership of the accessway for Parcel 1. OK.
5. Please provide signatures from all affected parties on the preliminary title report
consenting to the subdivision. OK.
6. Please provide two copies of the drainage study or explaining the drainage area
tributary to the subdivision and a statement setting forth in detail the manner in which
storm water runoff will enter the subdivision are required. OK.
7. Provide a statement of proposed improvements and landscape modifications that are
necessary to satisfy parking requirements and the accessway to Parcel 1. OK.
8. Demonstrate compliance with applicable standards of Table 3 in 16.18.030 except for
requirements that would physically preclude the development of an 800 square foot
dwelling unit. Comment Remains. Please provide a statement stating how the
project cannot satisfy applicable standards. Please specifically identify the
objective standard that physically precludes the project from providing a 20’
access easement or access way and why the project is unable to comply. The
proposed exception is only required because there are no feasible design
options which could allow for site development of two minimum 800 square
foot units on either of the two resulting parcels. For the purpose of this
finding, existing improvements or development is not considered a physical
constraint.
A 20 ft access easement cannot be provided due to the existing home location. The
home was a rental within the last 3 years and cannot be altered or modified to provide
a 20 ft access easement, we request an exception to that development standard as it
would preclude us from doing an urban lot split. See California Government Code
section 66411.7(a)(3)(D)(iv).
If the city has a suggestion on a way forward we are open to suggestions. As you know
SB9 does not allow you to deny the subdivision because of development standards not
being met.
9. If the project is proposed as a Flag Lot Subdivision demonstrate compliance with all
objective standards identified in Section 16.18.060. Understood that this is not a
Flag Lot Subdivision.
10. If the project is proposed as a Common Interest Subdivision demonstrate
compliance with all application requirements and objective standards identified in
Chapter 16.17. Understood that this is not a Common Interest Subdivision.

The Fire Marshal has significant safety concerns regarding the occupants of
the land-locked parcel being able to safely egress to the public way
considering the tight passage along the existing residence on a parcel the
occupants of the rear property have no control over, does not have fire
sprinklers and heat exposure from a structure fire would pose an eminent
risk to those escaping to the public way and a reasonable size area of refuge
is non-existent. For safety reasons, the fire department can’t support the
application as submitted unless the applicant provides a map that conforms
to the City’s lot frontage requirements that provides both egress and fire
department access to the rear parcel. Comment Remains. [California

Spoke with Roger regarding access. Currently there is 7.65 ft between the existing
house and the property line. There is an additional roughly 3 ft of open area on the
other side of the property line that there is a prescriptive easement on as it has been
used as a driveway for the subject property for decades. So there is over 10ft between
the existing house and the neighboring fence which is more than sufficient. Even with
only the 7.65 ft we meet all of the codes cited by Roger. There are no windows on the
first story of the wall that is against the driveway. This seemed to satisfy Roger as well.

Requested exceptions: This project requires exceptions to the Depth, Street Frontage, Density
and potentially the FAR and Lot Coverage requirements of Sections 16 and 17 of the City’s
Municipal Code.
*Front, Interior and Rear Setbacks: The tentative parcel map shows a potential front setback
of 68’, interior and rear setbacks of 5’. This is consistent with the subdivision requirements.
The 19.8’ front setback and the 3.7’ rear setback for Parcel 2 are existing nonconforming.
California Government code section 65852.21(b)(2)(B)(i) states that no setback for for an
existing structure be required.
A building envelope for a future 800 sq. ft. residential unit is shown on the tentative parcel
map. The tentative building envelope conforms to all setback requirements.
**Lot Width/Depth/Street Frontage: Required lot depth is 90’ for R1 zoned property. The
depth of proposed Parcel 1 varies and is approximately 39-50 feet. Proposed Parcel 2 would be
68-80 feet. The underlying parcel size is approximately 120’ deep by 50’ wide, resulting in a
parcel size of 6,000 sq. ft. Given the physical dimensions of the existing lot, there is no lot
configuration that would allow for a 50 x 90’ size parcel.
Street frontage is required to be 20’ for each lot. The existing lot dimensions would allow for a
25’ x 120’ size lot, except that there is an existing house on proposed Parcel 2. SB 9
regulations prohibit demolition of an existing residential unit that has been rented out in the
past 3 years.
State legislation (SB 9 Urban Lot development) has overridden some local planning standards,
that when implemented, would preclude the construction of an 800 square foot residential unit,
or 2 units, on a parcel divided under SB 9 parameters. Here, implementation of the lot/width
local standards would preclude the subdivision and thereby preclude the construction of a
residential unit.
+Density: Density in the R1 zone is 1 dwelling unit/6,000 sq. ft. The proposed lots will result
in 1 dwelling unit/approximately 3,000 sq. ft. The physical dimensions of the existing lot are
approximately 120’ X 50’ = 6,000 sq. ft.
State legislation (SB 9 Urban Lot development) has overridden some local planning standards
regarding lot sizes and other standards, that when implemented, would preclude the
construction of an 800 square foot residential unit, or 2 units, on a parcel divided under SB 9
parameters. Here, the underlying lot is 6,000 sq. ft. There is no division that could result in 2
lots of 6,000 sq. ft. It’s impossible. SB 9 allows for the creation of lots to a minimum of 1,200
sq. ft. Both proposed lots would meet or exceed the SB 9 criteria for an urban lot split
16.23.020 Required findings and conditions for exceptions.
A. Before any exception is authorized, all of the following findings shall be made:
1. That the property to be divided is of such size or shape, or is affected by such
topographic conditions, that it is impossible, impractical or undesirable, in the particular case, to
conform to the strict application of the regulations codified in this title; the property to be
divided is 6,000 sq. ft. and is the smallest residential lot allowed under the City’s zoning
standards. Because of the size of the underlying lot, it is impossible and/or impractical to meet
the City’s standards for lot/width, setbacks and density.
2. That the cost to the subdivider of strict or literal compliance with the regulations
is not the sole reason for granting the modification; the cost to the subdivider was not taken
into consideration when designing this proposed urban lot split. The proposed design is based
on the property layout, City zoning regulations, SB 9 regulations, logical utility connections, and
logical accessibility requirements.
3. That the modification will not be detrimental to the public health, safety and
welfare, or be injurious to other properties in the vicinity: The modification will not be
detrimental to the public health, safety, or welfare because it does not change the uses or
residential nature currently established in the area. As designed, the project is consistent with
the requirements of SB 9 Urban Lot Split legislation and will contribute to California’s housing
crisis.
4. That granting the modification is in accord with the intent and purposes of these
regulations and is consistent with the general plan and with all applicable specific plans or other
plans of the city. Granting the modifications is in accord with the City’s goals/policies for in-fill
development, balanced communities, and accelerated housing production as discussed in the
Housing Element of the City’s General Plan. The modifications are also consistent with State
goals and policies to create more housing for all income levels.
B. In granting any exception, the commission or council shall impose such conditions as are
necessary to protect the public health, safety and welfare, and assure compliance with the
general plan, with all applicable specific plans, and with the intent and purposes of these
regulations. (Ord. 1490 § 3 (part), 2006). Here, it would be up to the Planning Director/City
Engineer to impose any necessary conditions and the conditions would have to be consistent
with City policies and SB 9 regulations.
