PURPOSE AND INTENT
GENERAL
The purpose and intent of hese Design Standards is to clarify and consolidate
present design criteria in the City of Lodi.
SCOPE
The Design Standards as hereinafter specified shall be used as the basis of design
for all development within the jurisdiction of the City of Lodi.
DESIGN
The design of each development is in itself a special case and these Design
Standards shall not be construed to be the maximum required design on all or
any separate phase of the construction. Under certain conditions, any or oil
phases of the development may be required to exceed these specifications. It
is also recognized that there may be developments where it is impossible to meet
these Design Standards. It is suggested that these cases be reviewed with the Public
Works Director early in the design process to minimize reworking plans where
deviation is not permitted.
Contact City of Lodi Utility Department for the design of electrical facilities.
FINAL AUTHORITY
The Public Works Director shall be the Final authority on all questions which may arise
as to the interpretation of these standards. The Director's decision shall be final
and he shall have authority to enforce and make effective such decisions. For
appeals from the Director's decisions see Section 22-9 of the Lodi Municipal
Code.
GENERAL NOTES
The typical General Notes required for all off-site improvement plans have been
included as Appendix A of these Design Standards.
•
BID ITEM ORDER
The bid item order and units for improvement plans have been included as
Appendix B of these Design Standards.
CHECK LIST
A check list has been included in Appendix C of these Design Standards in order
to familiarize the development engineer with some of the items checked by the
City to insure compliance and completeness of the improvement plans.

STORM DRAIN DESIGN EXAMPLE
The following procedure, based on the Rational Formula Q = CiA in conjunction
with the City of Lodi Design Standards, is used in determining design Q's for
City of Lodi projects. A runoff calculation example is attached, and referenced
to, far the purpose of illustration.
Procedure
1. On a plan, preferably 1" = 100' scale, show proposed street system,
existing and proposed drainage systems and delineate tributary sub -areas.
(See sheet 3)
2. Assume initial time of concentration (Ti), roof to gutter runoff time,
normally 25 minutes.
3. Calculate travel time (Tt) to the first inlet. Assume average velocity
in curb and gutter to be 1.5 feet per second.
4, The time of concentration (To) to the inlet is then the sum of the initial
time of concentration and the travel time. Tc Ti Tt (See sheet 4,
line 1).
5. Determine "i",. rainfall intensity in inches per hour, for a time equal to
the time of concentration (Tc) from the attached Rainfall Intensity Table,
City of Lodi Standard Plan 606.
6. Determine "C", coefficient of runoff using C values given in City of
Lodi Design Standards.
7. Determine "A", the area of the tributary sub -areas to the nearest 0.1
acres.
8. Compute Q = CiA, where Q equals the peak flow in cubic feet per
second (see sheet 4, line 1).
9. Considering all criteria (available slope, cover, hydraulic grade line
etc.), establish pipe size and slope, then determine pipe velocity and
travel time (Tt) required to carry above Q to the next M. H. inlet or
M.H. confluence. Use Manning's "n" equals 0.013 for all pipes.

10. Compute new time of concentration to next M. H. inlet or M.H. confluence.
Tc2 Tc 1 + Tt2
Tc2 = 27.0 + 0.6 + 3,3 = 30.9 min. (See sheet 4, line 1, 2, & 3)
At M.H. inlets compare the new Tc2 for the pipe system upstream
to the Te for the tributary sub -area which contributes to the M.H.
inlet. Calculate the total peak flow at the inlet, using the longest
Tc and the procedure outlined above for determining C and i. (See
sheet 4, lines 4 and 5) . Then proceed downstream in the same manner
outlined in steps 9 and 10.
At M.H. confluences compare the Tc for each leg of the confluence.
Calculate the total peak flow at the confluence using the longest Tc.
(See sheet 4, lines 9 &. 10). Then proceed downstream in the same
manner outlined in steps 9 and 10.
