Response to Site Plan Review :
Dear Robert:
This is a response to the recently received Site Plan Review
completed by you. As per your instructions, we are
enclosing two copies of the revised documents and this
letter which addresses each item on your list.
•
Site Work:
1. This project has very little s' -e work which would
contribute to erosion. The ly site work involved are
the borings for the main •.les for the building, j
individual pad footing at a few places, and one small % ,� ij
piece of existing si• -walk demolition and reconstruction. '
All parking curre y exists_and is fully paved with AC. ` d
paving. Scope s work for-- parking lot is to re -seal /
only. Is th -- eany'ne for erosion control with this ∎ ,�
scope of work? 7.
2 See enclosed re onse from the Structural Engineer,
Berry /Nordlin Structural Engineers.
3., Since the new building is to be an addition to an
existing building, all grades are relative to the
existing building. See Ground Floor Plan, Sheet A2.la •
•
for all relative elevations. The parking lot is existing
and will not be modified. All sidewalks around the •
building (as shown on sheet A1.1 and A1.2) are to be
reconstructed in their existing locations at a slope less
than 1:12. The sidewalk work was previously permitted
under phase 1, using the same documents as submitted with
this phase.
4. The parking lot is existing and the scope_of the project
does not include any regrading of the parking areas.
This work was previously permitted under phase 1, using
the same documents as submitted with this phase. See
• attached drawings from Phase 1.
5. The extent of the existing utility system is shown on the
enclosed utility plan which was submitted in the previous
permit submission for phase 1.
6. Roof drains will be connected to the existing storm
drainage system.
7. "Hydrant Flow Test Report Form" and. "Fire Flow Worksheet"
will completed as soon as possible and returned to your
office. These forms were not included with the site plan
review. ' ,
Accessibility:
1. This accessible way was permitted under the phase 1
permit process.' This accessible way is shown on sheet
A1.1, which has been marked -up for clarification and
which has been enclosed.
2. Minimum clear widths hava been met as. shown on drawings
1/A1.2 and 1 /A2.la.
3. All accessible routes have a clear continuous minimum
height as per 1109.4.2 and as shown on the building
. sections on sheets A4.1 through A4-.7.
4. All sidewalks are a minimum of 5' wide with the exception
of the sidewalk to the North of the pool, which is only
4' wide. This sidewalk is only 146' long (less than the
200' maximum - permitted by code) and also has a passing
space,where it is intersected by-the sidewalk from the
community meeting room.
Please call if you have any questions.

Site Plan Review
Dear Paul:
The following discussion is our response to Site Plan Review comments for the
Villa La Paz project which relate to structural items.
Comment: Provide a liquefaction potential and soil strength loss report (OSSC,
Section 1804.1.1 and 1804.5).
Response: Given the small size of the project, a soil investigation was not
conducted. The structure has been designed for foundation allowable
bearing and passive pressures corresponding to Materials Class 4 in
Table 18 -1 -A of OSSC. These allowable pressures are conservative
values which are typically assumed in the absence of a soil report.
Since the project consists of single story wood construction with a
total square footage (existing plus new) of approximately 1600
square feet, can the liquefaction/soil strength loss report be waived?
Comment: Structures shall be designed for seismic forces coming from any
horizontal direction (OSSC, Section 1628.1).
A. Provide a seismic lateral forces analysis prepared in
accordance with OSSC, Section 1628.
Response: See enclosed structural calculations.
' 1
Comment: We are unable to ascertain whether the roof structural elements have
been designed to include the additional weight of the HVAC units.
A. Submit the engineer's analysis of the roof structural members
supporting the HVAC (OSSC, Section 106.3.2).
Response: HVAC units are bidder designed items, and their exact sizes, weights,
etc. are not known at this time. When the data on these units are
known, it will be provided to the roof truss designer for
incorporation into their design of the pre- engineered trusses. See
revised Drawing S4 (enclosed).
Paul, we trust that this letter address the structural items in the Site Plan Review.
Please contact our office if you have any questions.
Sincerely,
John A. Tesner, P.E.
