Re: 1805 Shelburne Road
Dear Rocky:
ZONING ADMINISTRATOR
658-7958
On Monday you requested and were granted a certificate of occu-
pancy for your Shelburne Road location Upon review of your site
plan I found that certain improvements were not completed. Your
site plan included the installation of a fire hydrant and the
construction of a sidewalk along the frontage of your lot. You
will be required to complete these improvements within the next
30 days.
My records indicate that we still have your performance bond
which includes landscaping, sidewalk and hydrant. Should you
fail to comply we will be forced to call in the bond.
If you have any questions please don't hesitate to call me.
Very truly,
Richard Ward,

approved as written. Mr. Belter seconded, and the motion
passed unanimously.
Consider request by Nordic Ford/Toyota for a 6-month
extension of the site plan approval granted on 9/24/85, for
construction of a 14,000 sq. ft. building at 1620 Shelburne

Mrs. Lafleur advised that the applicant has been working to
meet Wagner, Heindel & Noyes requirements which are very
strict. The parking lot configuration has been changed with
some spaces in back removed.
Mrs. Hurd moved that Nordic Ford/Toyota be granted a 6-month

„ Consider request of Rocky Clayborne for 6-month extension to
site plan approval granted August 6, 1985 for construction of
a car wash at 1432 Shelburne Rd.
When Holmes Rd. is extended to the east, access will be
changed to Holmes Rd. 'There has been some discussion on
developing land to the east of this parcel; 2-4 acres, which
is zoned residential and commercial, and there is talk of the
2 lots joining up. If Rocky doesn't do the carwash, he will
have to put the sewer allocation back into the pool. The
concensus of the members was that they wanted Mr. Clayborne
to come back for further discussion with the Commission.

3) ROCKY CLEBORNE, 1432 SHELBURNE ROAD
Rocky Cleborne requests an extension to the site plan that
was approved by the Commission on August 6, 1985. This
approval expired on February 6, 1986. Since this extension
request was received on February 4, 1986 I suggest we
consider it a request for an extension rather than starting
over. ,�-
There is some discussion about combining this property to DOD
with the 4 + acre parcel to the south and east that is
owned by Thomas Farrell. That parcel is zoned Commercial-1
and Residential-4 and will require a Planned Commercial
Development approval as well as a full traffic study.
I am enclosing the minutes of August 6, 1985 to answer your
questions regarding the traffic figures. Cleborne should
be present to answer any questions.

4) G.S. BLODGETT, 75 FARRELL STREET
The applicant requests an extension to the site plan approval
granted on September 17, 1985. It expires on March 17, 1985.
The conditions of the property are essentially unchanged and
the 6 month extension should be granted with the stipulation
that all stipulations of September 17, 1985 shall remain in
effect. The building permit will have to be obtained within
6 months of March 17, 1986.
5) CHINA LITE, CORPORATE WAY
The applicant proposes to construct a 60' x 12' greenhouse
addition to the northern end of the restaurant for additional
seating. Other sections of the restaurant will be reorganized
with a resulting capacity of 371 seats. The live entertainment
will be eliminated.

2) NORDIC FORD, 1620 SHELBURNE ROAD
The site plan approval granted on September 24, 1985 expires in
a month. The applicant requests a 6 month extension to the
approval.
Over the past 5 months the applicant has been working with
Wagner, Heindel and Noyes and the City to meet our erosion
control policy for this development. After numerous reconfig-
urations of green space, retention ponds and drainage areas,
the plans meet our requirement for the runoff. to not exceed
pre -development conditions for the entire site. (See attached
letter from Alexander/Truex/de Groot, Inc.)
I see no reason why this can not be- extended for 6 months.
3) ROCKY'S CAR WASH, SHELBURNE ROAD
The applicant requests an extension to the site plan approval
granted on August 6, 1985. I received this request prior to
February 6, 1986, the date of expiration. (See enclosed letter)
4) DESLAURIER, EAST TERRACE
The applicant requests a clarification of the Planning Commission's
intent for the 50 foot right-of-way to this 1.29 acre parcel.
It is his contention that the land was rezoned to R4 from C-1
so that this property and the Quarry Hill Club property could
"use this r.o.w. . to East Terrace. If the Commission intends to
not allow any other access through this r.o.w., Mr. Deslauriers
requests that the 4 acres of the golf course that are presently
R4 be rezoned to C-1. (See enclosed map)
5) CHINA LITE, CORPORATE WAY
The applicant proposes to construct a 60' x 11' greenhouse add-
ition to the northern end of the restaurant for additional seat-
ing. Other sections of the restaurant will be reorganized with

attend this meeting since your letter does not meet the require-
ments for a request for an extension. You must provide a reason-
able amount of evidence of intent to pursue the project and ~rAT
conditions are unchanged since the time of the original approval
(section 20.302).

Continue Discussion on Site Plana lication of Rocky Cla bourne,
or construction oa drive-throu Acarwashat 1452 Shelburne Rd.
The architect explained that all washing & drying of cars will
take place inside the building. There will be gas pumps in front,
but only for the convenience of people who also want to pick up
gas at the same time. They will be planting some additional
trees. When the street comes in across from Holmes Road, the
access will be changed to come off that road.
Roger Dickinson presented his firm's traffic study figures.
They put an automatic traffic counter at Rocky's Essex Junction
location beginning on a Friday, through the weekend, until the
following Thursday. Counts were taken hourly. They found that
the peak traffic was Saturday and Sunday mornings, averaging 15
vehicles per hour, the equivalent of 30 trip ends. During the
weekdays, the noon hour and the pm peak hour experienced 10 cars
per hour, or 20 trip ends. He noted that winter months see higher
use than summer months. In estimating traffic at the Shelburne
Road location, Dickinson felt that there would be 41 trip ends
per hour on weekdays and 61 trip ends per hour on weekend mornings.
He added that on Shelburne Rd. traffic is higher in summer than
in winter months.
Ms. Bechtel asked if it was possible to compare traffic levels
on Pearl St., Essex Junction and this location on Shelburne Rd.
Mr. Dickinson replied that both locations are major arterial
highways, 4 lanes or greater in width. Shelburne Rd. in this
area has about 24,000 vehicles per day, and Pearl Street in Essex
Junction has about 20,000. Me felt this was not a significant
difference and the 2 locations could be compared for this purpose.
Mr. Dooley noted that on July 28, 1984, based on Rocky's figures,
the peak was 67 cars while on March 24, 1984, the peak was 569
cars. He said this was not an ignorable difference. He stressed
that based on one weekend in July, they were calculating 61 trip
ends per weekend morning. Mrs. Hurd noted that even this was
exceeding the traffic overlay.
Lengthy discussion rose about the interpretation of the traffic
overlay zone. Mr. Dooley said it was his understanding that
either criteria applied, either 80% of the highest hourly volume
for the adjacent street or 7 AM - 6 AM, Monday -Saturday. As
long as the peak hour occurs in that time period, it is a peak
hour. In this instance the peak occurs on Saturday morning, so
it is a peak hour.
Mr. Jacob asked what they estimated traffic would be from 4-5 pm.
Mr. Claybourne said very few because people don't want to get out
of the line of traffic on their way home from work.
PLANNING COMMISSION
6 AUGUST 1985

It was noted that in the latter part of April, 1984, just north
of McIntosh, the highest hour was Friday, 4-5 pm, with 2,264
vehicles per hour. 80% of that is 1800 vehicles per hour. The
Saturday volume of 1840 is just about that 80% figure. Mrs.
Maher explained that they are thus talking about waiving or not
waiving the traffic overlay zone requirement.
Mr. Krassner asked how many cars can be stacked up on the pro-
perty. Mr. Claybourne said over 50, which is as many cars as
they can wash in an hour.
Mrs. Maher polled the members about waiving of the traffic re-
quirement. Mrs. Burgess, Belter, McClary and Jacob and Mrs.
Maher felt it could be waived. Mr. Dooley and Mrs. ?curt were
opposed.
Mr. Doolev then moved that the South Burlington Planning Commissia
approve the Site Plan application of Rockwell Cla borne for the
construction oa 13,000 sq. ft. car wash facilityat 1432 Shelbur
as depicted on a plan entitled e Plan, oc s ar Wash,

RE: August 6th Agenda Items
DATE: August 2, 1935
2) EAST TERRACE, MULTI -FAMILY CONVERSION
The City Attorney has verified that this project qualifies as a subdivision. According
to our regulations multi -family projects qualify as major subdivisions. Multi -family
is defined as three or more families (units).
Although the ordinance calls for this to be treated as a major subdivision, (2 Public
Hearings), the City Attorney has agreed that the Commission could rule it a minor
subdivision since it is a conversion of an existing structure, it requires no new
streets or public facilities, and it will have no increase in the building foot print.
This qualification will allow the application to proceed with only one public hearing.
The Commission should clearly state the reasons that this will be considered a minor
subdivision in order to distinguish it from future multi -family developments that
truly should be considered major subdivisions.
There is no prior application for this lot in either the files or individual recollections.
There was a proposed 4-unit DesLaurier Subdivision across the street that was denied
by the Zoning Board in 1980. It was zoned C-1 at the time and a variance was needed
for residential use.
A sewer allocation will be needed for this 4-unit dwelling and will be charged the
sewer fee. Nine parking spaces are required. Lanscaping should be shown for Final Plat.
3) PARK AND FLY
The City has a $30,000 letter of credit from Mr. Gregory for the completion of the
street and utlities. To date, the base is down. The letter of credit stated the
street is to be completed by Augusrttl5 '1985. If it is not, we will act on the letter
of credit. The stipulation of the Reprographics building on lot #1 required the
street to be completed prior to occupancy. There is no reason not to act upon this
site plan application as well in a similar fashion.
4) ROCKY'S CAR WASH
Mr. Clayborne will be providing -traffic information prepared by Roger Dickinson of
Fitzpartick-Llewellyn. (Enclosed) It was taken at the Essex Car Wash this past week.
Erosion Control information is also expected.
5) NATIONAL CAR RENTAL, 344 DORSET STREET
The applicant proposes to change the use of an existing building (formerly Climate
Control) to a printing business and the National Car Rental business. The property
is zoned C-2. The Zoning Board approved this for multiple uses.

1. Gravel parking area will have a slope in excess of 8%.(8..feet..
in 100 feet) this will subject the area to washouts. I would
recommend the material be the so called plant mix type which is
subject to washouts.
2. Parking rows should be deliniated with concrete pumpers.
3. Site should include drainage inlets with traps, to intercept
the runoff, and piped to the street system.
6) ROCKY'S CAR WASH, SHELBURNE ROAD
1. This site shall include a storm water retention area designed
by a professional engineer to control runoff. This shall be in-
cluded in a site drainage plan.
2. Storm drainage pipe shall be plastic or concrete pipe.
7) AUTOMATED FLIGHT SERVICE STATION, AIRPORT DRIVE
1. The entire site drainage plan must be submitted for review.
The existing drainage swale discharging northerly from this site
has been a problem. This must be studied, including the closed
system it discharges into, to see if it can handle this extra
flow. An alternate may be to drain the site into the Airport
Drive storm sewer system.
8) BROCKWAY AIR, CALKINS COURT
1. A site drainage plan shall be submitted.
2. The purpose of the connecting drive to the 50' easement is
not clear,also access to the northerly parking area.

Circulation and Access: recess is from the west side of Gregory
Drive. There will be a separate entrance and exit. Circulation
is provided around the proposed building and throughout the parking
lot.
Parking: The plan shows 227 parking spaces. Ninteen are for public
use; 208 are vehicle storage for Park and Fly patrons. According
to the traffic study of David Spitz, most vehicles will be parked
1.6 to 3.5 days on the average. Most of the lot is unpaved.
Landscaping and Screening: The plan meets the landscaping requirement.
The landscaping consists of cedar hedge, lilac bushes, linden, crab-
apple, euonymous spindle tree, and norway maple. A $7600 landscaping
bond must be posted.
Other: See Szymanski's comments. The traffic data of Mr. Spitz
indicates that 4 vans will shuttle users at 15 minute intervals,
unless there are no airplane arrivals. The traffic peak is estimated
to occur at 10-11 A.M. and 6-7 P.M. rather than peak Williston Road
hours. The entire subdivision was allowed 125 trips per peak hour.
This use projects 40, bringing the total to date to 60. Before the
fifth lot is to be developed the entire development is to be reevaluated.
The State required a flashing yellow light at the top of the hill,
a sign at the bottom warning of trucks entering and a decelleration
lane into the development.
6) ROCKY's CAR WASH, 1432 SHELBURNE ROAD
The applicant proposes to construct a drive -through car wash at
the site of the former Melandy's Chain Saw repair on Shelburne Road.
The property is zoned C-2 and car washes are a permitted use. The
existing building will be removed.
1'
Traffic: The property is in overlay zone 2; 48 trips per'hour are
allowed on this 2.2 acre lot. The ITE data sows an average of �10
trips during the peak hour on the adjacent street and:l32 trips
per peak hour during the weekday peak hour of the use. The applicant
estimates a maximum of 80 trips would occur on sunny Saturdays betv,-een
the hours of 12 and 2 P.M. Saturdays are known to be the peak day
of a car wash.
Access & Circulation: A 36 foot driveway is shown from the lot onto
Shelburne Road. A two lane exit is shown for separate right and
left turn lanes. The two existing curb cuts will be closed. The new
Memorandum

one is on the southern property line.
The property abuts land where the planned extension of Holmes Avenue
is (owned by Farrell). As was stipulated with the Burger King on
Shelburne Road, access to this lot should be moved to this proposed
road when the road is built. The access to Shelburne Road should
be closed at that time.
Parking: Thirteen parking spaces are shown.
Landscaping & Screening: There is an existing cedar hedge on the
northern property line along Handy's property. The ordinance re-
quires $10,500 in landscaping and a bond must be posted. Approximately
$7000 worth of new plantings is shown. Credit is requested foi
the existing plantings valued at $3,500.
Other: A sewer allocation will be needed. The applicant projects
4200 gpd. This will be charged the $2.50 per gallon set by the
Council.
The applicant is expected to produce the report from Wagner, Heindel
& Noyse for the erosion effects of this development and their re-
commendation to not increase the erosion. This is located on the
rth brook.
7) CYNOSURE, BURLINGTON INTERNATIONAL AIRPORT
The applicant proposes to construct an 8,000 square foot building
for an Automatic Flight Service Station. It is located at the end
of the former Dawn Court.
Circulation and Access: Access is at the northern end of driveway
that circulates in front of the terminal and out to Airport Drive.
Parking: Parking is provided for 71 vehicles.
Landscaping: The landscaping plan shows approximately $4500 towards
the $10,500 require by the ordinance. The applicant claim_ height
restrictions prohibits additional plantings. The front of this build-
ing is landscaped as is part of the parking lot.
Other: A sewer allocation of 375 gpd is needed at the fee of $2.50
per gallon. There is capacity to handle this amount.

The question of the road was raised, and Ms. Bechtel noted Mr.
Gregory had not yet completed work on it. The City has a bond,
and the time period for the work has not yet expired. Mrs.
?curd felt that no building permit should be issued until road
work was completed. Ms. Bechtel will check the wording of the
original subdivision motion.
Regarding traffic, Mr. Spitz reported that 125 trip ends are
allowable for this 6-lot development, roughly 20 per lot.
The first two lots cone in under that figure, and the proposed
project is right at that figure. In the same period during
which there were 110 accidents reported in the McDonalds location,
only 7 were reported at this location. Mr. Spitz said that the
peak hours for this location do not coincide with these for other
establishments.
The applicant stressed that the car servicing was only for "park
and fly" customers.
It was agreed to continue the request until the question of the
road work can be discussed further.
.onsider site plan applicatian of Rockwell Clayborne for con-
struction of a car wash _facility a
Mr. Lamphere explained that the site is across from Volkswagen.
It will have stacking capacity for 60-64 cars with strictly an
inside operation. Some new willows will be added to the land-
scaping. A storm drainage study is being done by Wagner, Neindel
& Noyes, and the applicant will provide a retention basin ox the
site. It is estimated that 4200 gpd will be required based on
Mr. Clayborne's Essex operation. The applicant stressed that
this is predominantly a carwash, not a gas station.
Ms. Bechtel noted that the area falls in overlay zone 2 and is
ct land where Molmes Road would be extended. (.trips per peak hour
are allowed. ITE informatian shows this facility would produce
110 trips per peak hour Which exceeds the zone allowance by more
than two times. Mr. Clayborne said the ITE data comes from only
1 source, Paul Box Associates who studied only 2 carwashes in
the Chicago area, which is 70 times the size of Chittenden County.
Mr. Box himself felt this was a limited sampling and added that
the stack -up area was a key factor with 25-30 cars being the
best recommendation. Mr. Clayberne noted they have capacity for
60. The building will also be set back 170 feet, 100 feet more
than the requirement. Me added that his peak day is Saturday
which would not interfere with regular weekday peak traffic.
Mr. Dooley raised the question of water run-off. Mr. Clayborne
said they recycle more than 75% of their water and that by law
run-off must be taken care of by interior drains.
PLANNING COMMISSION
23 July 1985

Mr. Dooley noted that he has consistently voted against Shelburne
and Williston Rd. projects which exceed allowable traffic figures
and that he would continue to do so. Mrs. Maher said they night
request data as to what traffic they would produce at peak hours:
7-9 AM and 4-6 PM; Mrs. Hurd added that peak hours on Saturday
should also be considered: 6-8 AM, 11-1 PM, and 4-6 PM. The
concenses of the Commission was that they wished to wait for
this information before proceeding.
Consider Site Plan Application of C nosure Inc. for construction
of an 8,000 sq. ft. buildingor Automated Flig#t Service Station-,
Airport Drive, Burlington International Airport
Ms. Bechtel reported that Mr. Goddette is now satisfied with
fire control measures.
Mr. Lamphere advised that in May, 1982, the federal government
sent out proposals in New York, Vermont, and New Mampshire for
an automated flight service station. There are now 360 in the
country, and all but 61 of these will be eliminated. In our area,
stations are currently located in Lebanon, N.M., Berlin, Vermont,
and Glens Falls, N.Y. The proposed facility will consolidate those
3. Cynosure, which is a sister corporation of GBIC, was awarded
the facility, which will be leased to the federal government for
one year, renewable for 3-25 years, for $1.00 per year. To make
this work, the state legislature appropriated $748,000; all costs
beyond this will be borne by Cynosure. The facility will employ
50-60 people in 3 shifts with $2,000,000 in salaries. This will
preserve jobs now held by people in Berlin and some of those in
Lebanon and Glens Falls. The facility will be tax-exempt; however,
if it is ever leased to a private concern in the future, it would
then be taxable.
Entrance to the facility will be from the main drive in front of
the terminal. At some future date, there will. be another access.
Dawn Court would not be used. The FAA will provide a tower facility.
Landscaping around the building will be kept low because of the
safety factor around the airport. All draina a will go to a
retention area and will not add to the airport problem. Water
will tie into existing mains and will give the continuing loop
Chief Goddette has been looking for. They will tie into the
sewer on Airport Drive and will have an allotment of 350 gpd.
Mr. Dooley questioned additional traffic in front of the terminal
building. Mr. Lamphere said it is possible to keep Dawn Court
as an access but that may cause more problems than they have now.
Mrs. Maher asked why there was no landscaping in the parking lot
area. Mr. Lamphere said this will eventually be done by the
airport. Me said they have no problem with continuing landscaping
around the parking lot. Miss Bechtel noted that $6,000 could
be reserved for future landscaping.

RE: Traffic Generation Rates
Rocky' s Car Hash, Essex Junction
FILE: 85079
Dear Mr. Cleborne:
At your request, He have evaluated trip generation rates at your existing
car wash at 124 Pearl Street in Essex Junction.
This existing facility consists of two bays, one containing a
semi -automated mechanical wash system and the other, two hand wash
stations. Gasoline is not sold at this facility. Four vacuuming stations
are also available for use by customers.
He understand that you have applied to construct a similar facility on
Shelburne Road in South Burlington, north of Holmes Road, on a 2.2 acre
parcel. The requirements of the South Burlington Zoning regulations limit
the maximum trip generation rate from this proposed car wash to 48 trip
ends per hour during periods of peak traffic volumes on Shelburne Road.
Because of the physical similarity between the existing (Essex Junction)
and the proposed (South Burlington) car Hashes, the trip generation rates
at each location should not differ significantly. Both are located on
major arterial streets Kith traffic volumes in excess of 20,000 vehicles
per day, further reducing potential differences in trip generation rates
between the two locations.
t.�
Traffic volumes at the existing car wash Here obtained by placing an
automatic traffic counter at this location from Friday, July 26th to(,?
Thursday, August 1, 1985. Peak traffic volumes Here observed to occur on
Saturday and Sunday mornings, with an average of15 vehicles per hour 30
trip ends) using the facility betwe6-K—"1t`Y0'-h. m. -1: 00 p. m. on Saturday.
Traffic volumes on Keekdays were observed o peak at a maximum of 10
vehicles per hour ( 20 trip ends) between 12: 00-1: Od p.'m. "amd 4:00-5: 00
p. M.

It is widely recognized that car Hashes, particuarly those in northern
climates, experience seasonal variations in their customer volume. The
magnitude of these seasonal variations have been documented by yourself by
maintaining daily customer volume records at the Essex Junction facility --�
during 1984. From these records and our recent traffic count, Re have �(p
calculated the annual average, peak vehicle generation rates to be 41 rip
�----
ends per hour on Heekdays and 61 trip ends per hour on weekend morn gs.-��
Seasonal variations also occur in traffic volumes on highways. Appendix A
illustrates monthly variations in traffic volumes at your Essex Junction
facility and the same for volumes on urban highways. The urban highway
trarfic volume information Has obtained from automatic traffic recorder
grouping studies prepared by the Vermont Agency of Transportation. Rhen
compared, it becomes evident that car -Rash generated volume
patterns differ significantly from adjacent street traffic volume
patterns. Your peak months are December through February, Rhen adjacent
street traffic volumes are at their lowest. Summer months, when adjacent
street traffic volumes are at their highest, are your slow periods. This
comparison Hill hopefully alleviate any concern which may exist about
potential impacts of seasonal variations in car wash traffic volumes on
adjacent street traffic flow.
He Rish to thank you for this opportunity to be of service. As requested,
Re are planning to attend the August 6th meeting of the South Burlington
Planning Commission to answer any questions concerning the potential
traffic impacts of your proposed car wash. Should you have any questions
concerning the above conclusions before this meeting, please feel free to
contact us.

Dear Jane:
This is to inform you that we have met with Mr. Dwight Baker of
Wiemann-Lamphere Architects to discuss plans for Rocky's Car
Wash located at the site of the Mollendi's Chain Saw repair
shop. We will be reviewing the hydrologic calculations which
have been performed and using the TR-20 computer model to assess
the impact of this development on peak streamflows and runoff
volumes in the North Brook watershed. Our final analysis will
be completed pending the receipt of a final site plan from
Wiemann-Lamphere. Please contact me if you have any questions.
Sincerely,

Re: Car Wash - Shelburne Road
Dear Jane:
I have a client, Rocky Clayburn, who is interested in the Brothers
Two Site on Shelburne Road just south of the site that was developed
by the Crane Family a few years ago.
The intent is to provide a car wash on the site and obviously with
this kind of use, the available sanitary sewer capacity is of great
concern to us and I think an issue which we need a reaction on before
we develop a great deal of plans for Site Plan Approval.
What I am requesting is that you research this and give us some idea
of our availability of approximate) 42'60 gallons per day or use
such as this. The system that we intend o ins a wit1Tr1i the
building is called International Autowash Systems and they use, in
the neighborhood of 50 gallons of fresh water per car and have a
reclaiming system which would reduce the waste water per car to
25 gallons per car, per wash.
We would appreciate it if you could review the above comments and
let us know if the capacity is available for this kind of use.
We look forward to hearing from you.
Very my yours,

846—Car Wash
Description: The car wash facilities cited are
semiautomated facilities in which the auto-
matic washing operation is preceded by inte-
rior cleaning and vacuuming by car wash per-
sonnel and followed by damp toweling to re-
move water and catch dirty spots which were
missed by the automatic washing. Most
facilities also have a car waxing capability in
which the wax is applied automatically in
liquid spray form at the end of the automatic
wash cycle. Gasoline is usually available for
purchase a is Me amount of purchase qualifies
the customer for a discount on the car wash.

REPORT/ANALYSIS OF HYDROLOGIC IMPACT
OF ROCKY'S CAR WASH DEVELOPMENT
ON NORTH BROOK
This report presents the results of our analysis of the
hydrologic impact by the proposed Rocky's Car Wash development
on North Brook. The location of the proposed Rocky's Car Wash
development is at 1342 Shelburne Road, in subwatershed 3 of the
North Brook watershed. The site is presently occupied by
Melendy's Chain Saw Shop and a private residence. The
hydrologic model for North Brook has recently been revised to
r more closely reflect the current drainage patterns within this
J area. A portion of the watershed surrounding the Rocky's Car
Wash site is shown on the schematic on page 1 of the Attachment.
Hvdroloaic Analvsis
To evaluate the impact of the proposed Rocky's Car Wash
development, we have examined the runoff response at section 3,
which is located just to the south of the site, on the small
tributary from the site which feeds into North Brook. The
design storm for this analysis was 25 year, 24 hour rainfall of
4.0 inches.
In
its
existing condition, the site
is
not
heavily
developed,
and
does
not appear to be contributing
to
the
erosion
problem in
2
North Brook. Although the curve number is relatively high
(CN=81), this is due to the fact that the underlying soils in
the area are predominately clay, and do not have the ability to
absorb large amounts of water. However at this time, two small
ponded areas exist on the site as shown on the site sketch
(Attachment, page 2). These ponds serve to provide some
buffering to peak stream flows during large storm events. The
filling of these ponds as a result of the development will
eliminate this existing buffering capacity. However, it does
not appear that any flow enters the site from upslope areas.
Although a 12 inch corrugated metal pipe was found at the
northern end of the northerly pond, field examination, as well
as interviews with local residents, revealed that this pipe is
no longer functional. Therefore the ponds serve to buffer only
runoff from the site itself.
We have used the TR-20 hydrologic model, and modified the North
Brook data file for subwatershed 3 to reflect the changes in
hydrologic response resulting from the proposed development.
The modifications which were made to the data file are shown on
page 3 of the Attachment. Computer runs were then made for both
the pre -development (existing) as well as the post -development
conditions. These runs reveal that the projected peak discharge
during the 25 year, 24 hour storm event is 6.00 cfs in the
existing condition and would be 8.92 cfs following the
W
development of the site, with no detention provided. The output
generated from the computer runs is included on pages 6-15 of
the Attachment. The expected runoff hydrograph during thedesign
storm is shown on page 4 of the Attachment. An expanded plot of
the portion of the runoff hydrograph which exceeds the
pre -development peak of 6 cfs is provided on page 5 of the
Attachment. From this information, we have computed that a
minimum storage volume of 1460 cubic feet would be required on
the site to prevent any increase in the peak discharge or
velocity from the site. The maximum volume required would be
` 5213 cubic feet, which equals the total volume of increased
J runoff from the site. The final design volume will likely be
between these two extremes, with a maximum discharge rate of
6.00 cfs for the expected maximum water surface during the 25
year, 24 hour storm. A spillway should be provided to allow
passage of larger storms without damage to the structure.
It should be noted that this analysis assumes that the runoff
from all modified portions of the site are routed through a
stormwater detention structure. However, the proposed detention
Nona
areas shown on the site plan developed by Weimann-Lamphere
Architects (dated July 5, 1985) would in fact service only a
portion of the impervious area on the site. In this case, it
may be necessary to overdesign the detention capacity for
certain portions of the site, so that runoff from other portions
4
of the site can be released without detention. Therefore it
will be important for us to review the final design of the
basins to include the proposed outlet structures.
This concludes our report on the proposed Rocky's Car Wash
development.
