pavers, a manufacturer’s detail for the pavers is required
. Done. But since in this submittal the pavers
are not being counted as pervious, the City has no requirements regarding how they are constructed and
installed. Please add to the Permeable Pavement detail the requirement that the base course of aggregate
shall have a minimum of 3” of storage and reference Handout E#72B all requirements.
25.Done. Call out rim and invert elevations for the existing CB on Bell St located northwest of the property.
Not Done. Revise to at minimum provide the option of standard material for this pipe, or specifically

Not done. Show the new sidewalk from property line to property line. Sawcut should be property
34.
line to property line. Make all changes to this plan (including the construction notes) when revising
sheet 4.
Not helpful. The frontage plan should not show underground piping or include call outs for the
utilities that are underground. It should show meters and cbs as final structures. There should be a call out
for the 2 ft sawcut. It should show the location of the required street trees. Call out width of sidewalk etc.
It should provide more information about the frontage improvements. Please add plan showing the frontage
improvements.

Subject: BLD20140613 -622 Bell St
Drainage Report
The second paragraph of page 1 says the project will have 3,990 square feet for the building footprint and the driveway plus
5,320
1,330 square feet of pavers. This total (not in the report) is square feet of impervious surface area. The third paragraph
5,2405,340
of page 1 says there will be square feet of impervious area. Sheet 1 of the plans say there will be square feet of
6,578
impervious area. The modeling has 0.151 acres of impervious area of square feet of impervious area. Re-calculate the
impervious surface area and make the number consistent between documents.
Minimum Requirement # 6 – Runoff treatment – Include the amount of pollution generating impervious surface planned for
the project.
Minimum Requirement # 7 – This section should say that this Category 2 Small Site project is located in Creek base (Shell
Creek) and is subject to the peak flow control standards of 0.07 cfs/ acre, 0.14 cfs/acre, and 0.33 cfs acre for the 2-yr, 10-yr,
and 100-yr recurrence events. Based on X,XXX square feet of proposed impervious area (fill in the amount based on the first
comment), the allowable peak discharge rates for the 2-yr, 10-yr, and 100-yr are x cfs, y cfs, and z cfs (calculate x, y and z by
multiplying the total impervious area in acres by the peak flow control standards). Re-model and re-design the detention
system as needed.
No text was found in the report that addresses Small Site Minimum Requirements #8, #9, #10, and #11. These requirements
shall be included.
Plans
Sheet 3:
Note 2 – CMP detention pipe is not per standard. Acceptable material for detention pipe are as follows:
Metal:
ACSP – Aluminized Corrugated Steel Pipe (Type 2 meets AASTO designations M274 and M36)
ASRP - Aluminum Spiral Ribbed Pipe (16 gauge or better)
CAP –Corrugated Aluminum Pipe (16 gauge or better)
DIP – Ductile Iron Pipe (Class 50 or better)
Concrete:
PCP – Plain Concrete pipe
RCP – Reinforced Concrete Pipe
Plastic:
PVCP – Polyvinyl Chloride Pipe (SDR 35 or better)
CPEP – Corrugated Polyethylene Pipe (smooth interior wall, or N-12® pipe)
RPP- Ribbed Polyvinylchloride Pipe
Pavers will have runoff during large storm events. Show how runoff from the paves enters the detention
system
Add a note that all pervious area will have compost amended soils per City handout E72C.
The new storm line from the detetion system to proposed CB#1 crossed a water line. Show the crossing in
profile to ensure no conflicts.
Sheet 5:
The two figures selected from the City policy on permeable pavement are for reference only and should not
be used as standard detail. Since these pavers are being counted as impervious and the detention system is
being sized to accept runoff of from them, no standard detail is necessary other than to indicate to the
contractor how they should be constructed.
