RE: 1983 Annexations
Dear Jack:
In connection wi th the proposed 1983 Annexations of Spenwick
Place Municipal Utility District; College View Municipal
Util i ty District; and the acreage lying between said Util i ty
Districts, I enclose herewith draft of a proposed Service
Plan, which must be presented an explained to those attending
the Public Hearing on November 9, 1983, and which thereafter
is attached to the Final Annexation Ordinance as an EXhibit,
and becomes a binding contract between the Ci ty and the resi-
dents of the annexed area.
Please examine carefully, review
heads, and give me your comments
additions, in time for preparation
bution at the Public Hearing.
wi th appropriate departme nt
for necessary deletions or
of a final draft for distri-
Jack, for the submission to the United States Justice
Department under the Voting Rights Act, we will need a demo-
graphic census of the area proposed to be annexed. I believe we
could use 1980 census official figures, if we can correlate the
census tracts to the tracts to be annexed. I bel ieve a census
of the entire tract, taken as a whole, will be sufficient for
our purposes at this time. The census should be broken down
between Caucasian, Nexican-American, Black, Orientals and other
mi nori ty popula t ions. Nex t, I think it would be he 1pful to
submit figures on our estimate of the population of the City of
La Porte as of October 1, 1983. This could be done by taking

the 1980 census and adding the building permi ts which have been
issued since that date, with our estimate of the number of people
residing in each of the houses which have since been constructed.
If this could be done by council district, I think it would be
helpful, so that we can demonstrate to the Justice Department
the large amount of growth which has occurred, and which will
continue to occur, in the Western area of the City.
Finally, I need a map to submi t to the Justice Department, wi th
about six (6) copies, colored to show the existing six council
districts, together wi th the proposed annexation tract shown in
a different color. I would like to have the information for
the Justice Department within the next thirty (30) days, to
expedite the filing of the Application, as the Justice Department
has sixty (60) days from the f i 1 ing of the Applicat ion to rule
on it, and may ask for an additional thirty (30) days' extension.
~le need to time the Justice Department filing so as to hopefully
have a final ruling from them prior to the filing deadline for
candidates for office in the April, 1984 elections.
Yours very truly,

SUBJECT:
The sludge transfer problem between the digester and thickener has continued
to the point of slowing process operations at the treatment facility. Too
much valuable time is expended attempting to keep the existing transfer
piping unplugged. I recommend that we carry forward the advise of the
engineers from Turner, Collier and Braden as soon as possible.

Re: Wastewater Treatment Plant
Engineering Analysis
Turner Collie & Braden Job No. 13-02000-003
Dear Mr. Hodge,
In accordance with your letter of authorization dated June 21, 1983
to perform detailed hydraulic and mechanical analyses of several
problem~ at the wastewater treatment plant, we have completed our
evaluation and are presenting our findings and recommendations in
this letter report. We plan to meet with you on Tuesday, August 2
to present this report and discuss our recommendations.
1. HEADWORKS - confirm adequacy of l8-inch sluice gate for bypass
of aerated grit chamber
~.
We ~ave analyzed the hydraulics of the bypass channel in the
headworks based on the following assumptions.
a. future average daily flow = 3.75 mgd
b. future peak flow = 2.5 times ADF = 9.375 mgd
c. return sludge flow rate = 3.75 mgd
d. five remaining gates in headworks (one at entrance to
grit chamber, two in each of the two bar screen
channels) are changed from l8-inch square sluice
gates to 36-inch wide full height openings with
slide gates
At the future average daily flow rate of 3.75 mgd and with
the five other gates modified as described above, our cal-
culations indicate that the maximum water surface elevation
in the head~orks will be 24.35 if the grit chamber is out of
service and all the flow is being bypassed. With the top of
wall elevation of 27.00, there will be 2.65 feet of freeboard
under average daily flow conditions. We consider this to be
acceptable.

.,.
At the peak flow rate of 9.375 mgd, the maximum water surface
elevation in the headworks will be 25.52 under the bypass
condition. This will result in a freeboard of 1.48 feet,
which we also consider acceptable.
Our conclusion is that the l8-inch sluice gate in the bypass
channel is adequate if the remaining gates are modified to
a 36-inch width. During periods when the grit chamber is
out of service for cleaning or maintenance, the raw sewage pump
station pumps should be controlled so that the flow rate from
the station does not exceed the design peak flow of 9.375 mgd
(6,500 gpm). The l8-inch sluice gate in the headworks bypass
channel is adequate and we recommend that no modifications be
made to that gate.
2. WASTE SLUDGE PIPING - check hydraulics of p~p~ng system for
transfer of waste sludge between the digester and the thickener
There have been a series of problems with clogging of the waste
sludge transfer pipe between the digester and thickener. The
pip~. is 8-inch diameter. There is over 200 feet of pipe
bet~een the thickener and the digester, and over 350 feet of
equivalent length including fittings. The waste sludge is not
pumped from the digester to the thickener. The difference in
water surface elevations between the digester and the thickener
provides the head to overcome friction loss and cause the
sludge to flow to the thickener.
We have analyzed the hydraulics of this piping system for a
wide range of possible operating conditions. Our analysis
indicates that the probable waste sludge flow rate in this
pipe is 150 to 200 gpm, with a corresponding range of velocity
of 0.96 to 1.28 feet per second in the pipe during wasting
periods. Since the wasting operation should not be continuous,
ther~ should be no flow at times during the day. In fact,
the wasting period should not exceed 2.5 hours at the current
plant design rate and 3.8 hours at the future design rate.
Under the most favorable operating conditions, our analysis
shows that the sludge flow rate will be approximately 300 gpm
during wasting periods, with a corresponding velocity of
1.9l feet per second.

The probable rate of flow in this pipeline is not high
enough to prevent settling of solids in this pipe, even
during wasting periods. Most of the time the rate of
flow will be zero, which will allow further deposition
of solids and will increase the potential for the pipe
to clog.

;''1:>rovided.',f Our cOnclusion'is that the' arrangement of the
structures and the piping system is very likely to con-
triQute to the pipe clogging and may be totally responsible
for the problem. This problem could have been minimized or
eliminated by locating the structures closer together,
increasing the difference in water surface elevations,
'providing a waste.. sludge. pump... station ;or by a. combination

Ou~'recommendations for operational procedures to minimize
th~~ problem are as follows.
a. Thoroughly clean the piping system.
b. Maintain the water surface elevation in the thickener
below the overflow weir, at or slightly above the
point of discharge in the center feed pipe. This
will require the operators to pump out or siphon the
supernatant, or else will require modifications to
the overflow trough and piping.
c. Maintain the water surface elevation in the digester
at the maximum practical elevation (approximately
elevation 23.19).
d. Minimize the wasting period so' as to maximize the
~waste sludge flow rate and velocity. Do not attempt
to waste continuously or for extended periods of time.
Flush the sludge piping with process water after each
wasting period.

In the long run, the most practical solution is waste
sludge pumps, and we recommend they be installed as soon
as possible. On an interim basis, a single pump.in a
temporary installation would be an improvement over the
existing condition.
3. GRIT HANDLING EQUIPMENT - check hydraulics and mechanical
equipment design for the grit pumP. cyclone. and classifier
system
--
There have been problems at the plant with overflow of the
grit classifier hopper after periods of grit pumping. From
. the grit chamber, there is a single 6-inch suction pipe
which splits to two 4-inch suction lines feeding the two
grit pumps. The grit pump discharge lines connect into a
common pipe which feeds the grit cyclone. The cyclone
overflow is piped to a drain line and into the plant sewers.
The underflow feeds directly to the grit classifier. The
classifier overflow is also piped to the drain line and
'into the plant sewer.
Wechave evaluated the hydraulic and mechanical design of
this system and have found it to be satisfactory. There
is-no apparent design problem which would cause overflow
of the classifier hopper. The pump suction, pump discharge
and drain piping are all adequately sized. The grit pump,
grit cyclone and the grit classifier are properly sized
and matched in capacity. We have considered a range of
possible operating conditions and have not identified any
design problems at any point in the possible range of
operation. .
There are several possible explanations of the cause of
the problem. The drain piping may be clogged or obstructed.
The equipment furnished may not be in accordance with the
specifications and approved shop drawings; i.e. wrong pump
size, wrong pump speed, wrong impeller, undersized cyclone,
undersized classifier, etc., or the equipment may be mal-
functioning, i.e. cyclone is clogged, classifier overflow
is clogged or obstructed, etc.

To determine the cause of this problem, we recommend the
following course of action.
a. Check all drain piping for obstruction or blockages,
including the cyclone overflow, classifer overflow
and the drain line to the plant sewer manhole. Clean
and flush all lines and establish that they are
flowing freely.
b. Check the cyclone and classifier overflows and pipe
connections for obstructions.
c. Check pump speed to deter.mine if it is in range
(approximately 700 rpm).
d. Check pump discharge pressure to determine if it is
in range (8-12 psig).
e. "If possible, check the pump discharge flow rate.
This can be done with a portable sonic type flow meter,
if one is available. Flow rate should be 150-250 gpm.
II everything appears to be in proper operating condition
and the problem is still unsolved, we recommend that the
she.aves on the grit pump be modified to lower the grit
slJrry flow rate to a point where overflow of the classifier
no 'longer occurs.
4. ELECTRICAL SWITCHGEAR ROOM - evaluate the electrical switch-
gear room heat and ventilation requirements
There has been a series of problems with overheating of
motor starters, particularly those for the rotor drives,
in the electrical switchgear room of the operations building.
The electrical switchgear room is located at the south end
of the operations building. The switchgear is contained in
a room with dimensions of 30 feet by lG feet. Most of this
area is used for storage. The space is not air conditioned
and does not have any exhaust fans, openings, louvers or
other such methods of ventilation.

.,.
The switchgear contained in the room includes a 37.5 KVA
transformer, a 75 KVAR capacitor, the main distripution
panelboard, motor control center A and the main righting
panel. Motor control center A contains a 15 KVA trans-
former, four size 4 motor starters, twelve size 2 motor
starters, and some smaller equipment. Four size 2 motor
starters are proposed to be added in the future. __
We have calculated a heat gain of 12,200 BTUH in the
electrical switchgear room due to the equipment contained
in this area. When the outdoor ambient temperatures are
high, the heat gain in the switchgear room is enough to
cause thermal overloading of the motor starters in motor
control center A. Unless the heat generated by the switch-
gear is ventilated, it can be expected that there will be
some problems with nuisance tripping during summer months
or unusually hot days. In order to prevent this problem,
it will be necessary to provide some form of positive
yentilation for the switchgear room.
We have checked the existing air conditioning unit for the
op~rations building to determine if it would be possible
to~dd the electrical switchgear room to the system.
Unf~rtunately, the addition of the calculated heat gain to
the existing air conditioning load would create a total
heat gain that exceeds the capacity of the system by 27
percent. Therefore, this is not a viable solution.
We have evaluated two other possible solutions. The first
solution would be to seal the wall between the storage and
switchgear areas, louver the exterior doors and install a
2300 cfm roof mounted exhaust fan. The second solution
would be to install two 2300 cfm roof mounted exhaust fans
and replace two of the windows in the storage room with
louvers. In either case, the fans should be two-speed
with double set-point thermostat control,
We recommend that the second solution be implemented,
i.e. install two roof-mounted exhaust fans. This will
permit ventilation of the storage area as well as the
switchgear room, and will have the added benefit of

providing some amount of backup in the event that one
fan breaks down. As an interim measure, we woulq
recommend that the exterior doors be left open on hot
days and portable fans be used to ventilate the area.

On October 1,' the 1983-84 budget for the City of La Porte went into effect.
Three areas of this budget contain funds for street paving. The General
Fund Budget includes $246,935 for street maintenance. The Capital Improvement
Budget includes $450,000 for reconstruction of streets, and $69,810 for
improvement of Coupland Drive. The Revenue Sharing budget includes $150,000
for street repair, material only.
TO:
DATE:
October 19, 1983
FROM:
The General Fund budget will be used for maintenance purposes, and could
include some reconstruction. The Capital Improvement Budget will be used
for reconstruction, and could include some new construction of unpaved streets.
Revenue sharing will be used for construction of unpaved streets, using force
account labor.
With.$150,OOO in Revenue Sharing, eight (8) unpaved streets can be constructed
this year. Per priority, determined by Council, these streets include Lemon
Lane, N. "p" St. east of 26th, Willowview, BattlevievT, East Plainbrook, Easy St.,
Mossy St., anG Flintrock.
If Council determines that the City will pave unimproved commercial streets,
$100,000 can be used from the Capital improvement budget. Designed with 28
foot wide stabilized subgrade, 26 foot wide rock base 8 inches deep, and 26
foot wide asphalt surface 2 inches deep, approximately 7,000 square yards can
be paved, using contract prices obtained from the last Lomax street project.
Council will set priorities for paving commercial streets if the project is
approved.

RE: 1983 Annexations
Dear Jack:
In connection wi th the proposed 1983 Annexations of Spenwick
Place Municipal Utili ty District: College View Municipal
util i ty District: and the acreage lying between said Util i ty
Districts, I enclose herewith draft of a proposed Service
Plan, which must be presented an explained to those attending
the Public Hearing on November 9, 1983, and which thereafter
is attached to the Final Annexation Ordinance as an Exhibit,
and becomes a binding contract between the Ci ty and the resi-
dents of the annexed area.
Please examine carefully, review
heads, and give me your comments
additions, in time for preparation
bution at the Public Hearing.
wi th appropriate department
for necessary deletions or
of a final draft for distri-
Jack, for the submission to the United States Justice
Department under the Voting Rights Act, we will need a demo-
graphic census of the area proposed to be annexed. I believe we
could use 1980 census official figures, if we can correlate the
census tracts to the tracts to be annexed. I believe a census
of the entire tract, taken as a whole, will be suff icient for
our purposes at this time. The census should be broken down
between Caucasian, Mexican-American, Black, Orientals and other
minori ty populations. Next, I think it would be helpful to
submit figures on our estimate of the population of the City of
La Porte as of October 1, 1983. This could be done by taking

the 1980 census and adding the building permi ts which have been
issued since that date, with our estimate of the number of people
residing in each of the houses which have since been constructed.
If this could be done by council district, I think it would be
helpful, so that we can demonstrate to the Justice Department
the large amount of growth which has occurred, and which will
continue to occur, in the Western area of the City.
Finally, I need a map to submi t to the Justice Department, wi th
about six (6) copies, colored to show the existing six council
districts, together wi th the proposed annexation tract shown in
a different color. I would like to have the information for
the Justice Department within the next thirty (30) days, to
expedite the filing of the Application, as the Justice Department
has sixty (60) days from the filing of the Application to rule
on it, and may ask for an additional thirty (30) days' extension.
We need to time the Justice Department filing so as to hopefully
have a final ruling from them prior to the filing deadline for
candidates for office in the April, 1984 elections.

[The Following is Exhibit A]
SERVICE PLAN
FOR
A TRACT OF LAND COMPRISING
THE SPENWICK PLACE MUNICIPAL UTILITY DISTRICT:
THE COLLEGE VIEW MUNICIPAL UTILITY DISTRICT:
AND THE ACREAGE LYING BETWEEN SAID UTILITY DISTRICTS:
INTRODUCTION
This Service Plan ("Plan") is made by the City of La Porte,
Texas ("City") pursuant to Section lO of the Municipal Annexation Act
art. 970a, V.A.T.S., (Vernon's Supp. 1982) (the "Act"). This Plan
relates to the annexation by the City of a tract of land ("Tract") com-
prising the Spenwick Place Municipal Utility District: the College View
Municipal Utility District: and the acreage lying between said utility
districts. The Tract is described by metes and bounds in "Exhibit B"
which is attached to this Plan and to the annexation ordinance of which
this Plan is a part.
II. TERM: EFFECTIVE DATE
This Plan shall be in effect for a term of ten years commencing
on the effective date of the annexation of the Tract. Renewal of this
Plan shall be at the option of the City. Such option may be exercised
by the adoption of an ordinance by the City Council which refers to this
Plan and specifically renews this Plan for' a stated period of time.
III. SERVICE PROGRAMS
A. In General. This Plan includes two service programs:
(i) the Early Action Program, described below, and (ii) a Capital
Improvement Program, described below.
B. Scope and Quality of Services. Services under this Plan
shall equal or exceed the number of services and the level of services
in existence in the Tract prior to annexation. However, it is not the
intent of this Plan to require that a uniform level of services be pro-
vided to all areas of the City (including the Tract) where differing
characteristics of topography, land utilization and population density
are considered as sufficient basis for providing differing service
leve Is.
C.
I.
Definitions.
l. As used in this Plan, providing services in-
cludes having services provided by any method or means by which the
City extends municipal services to any other area of the City. This
may include causing or allowing private utilities, governmental
entities and other public service organizations to provide such
services, in whole or in part.
2. As used in this Plan, the phrase "standard pol-
icies and procedures" means those policies and procedures of the
Ci ty applicable to a particular service which are in effect ei ther
at the time that the service is requested or at the time that the
service is made available or provided. The policies and procedures
may require that a specific type of request be made, such as an
application or a petition. They may require that fees or charges
be paid, and they may include eligibility requirements and similar
provisions.
D.
Early Action Program.
1. Statutory Services. The statutory services will
be provided within the Tract within sixty days after the effective
date of this Plan, except as otherwise indicated. The statutory
services are as follows:
a. Police Protection. The Police Department
of the City will provide protection and law enforcement in the Tract.
These activities will include normal patrols and responses, the
handling of complaints and incident reports, and other usual and
customary police services.
-
...
b. Fire Protection. The Fire Department of
the City will provide fire protection in the Tract.
c. Solid Waste Collection. Residential col-
lection services will be provided by City forces. Non-residential
service and future residential service will be governed by standard
policies and procedures.
d. Maintenance of Water and Wastewater Faci-
lities. Those water and wastewater facilities included in the
Capital Improvement Program, below, will be maintained by an appro-
priate division of the Department of Public Works or, for a limi ted
period of time, by a conservation and reclamation district which is
.
to be dissolved. Should any extensions of such facilities be made
within the Tract, normal maintenance services will be provided.
e. Maintenance of Roads and Streets (includ-
ing lighting). The Department of Public Works will provide mainte-
nance of roads and streets over which the City will have jurisdic-
tion. (See Capital Improvement Program, below). The City of La
Porte will provide services relating to traffic control devices for
such roads and streets, and will provide street lighting for such
roads and streets through the Houston Lighting and Power Company or
by other means.
f. Maintenance of Parks, Playgrounds and
Swimming Pools. As indicated by the Capital Improvement Program, it
is not necessary to acquire or construct such facilities in the Tract,
so there are none to be maintained. Should any such facilities be
constructed by the City within the Tract, the Department of Parks and
Recreation will provide maintenance services for them.
g. Maintenance of Any Other Publicly-owned
Facility, Building or Service. Those drainage facilities included in
the Capi tal Improvement Program, below, will be maintained by the
Department of Public Works, as needed. Should any such facilities,
buildings or services be constructed or located by the City within the
Tract, an appropriate Ci ty department will provide maintenance services
for them.
2. Additional Services. Certain services, in addi-
tion to the statutory services, will be provided within the Tract to
the same extent they are provided to similar territories elsewhere
in the City. These are as follows:
a. Library services from existing facilities
and future facilities outside the Tract.
b. Health Services in accordance with stan-
dard policies and procedures.
c. Emergency Rescue and Ambulance Services
by the Ci ty I S contract or, La Porte Area Emergency Corps, in accor-
dance with standard policies and procedures.
E. Capital Improvement Program. The City will initiate
the construction or acquisition of capital improvements necessary
for providing munic ipal services for the Tract. Those improvements
which are necessary are indicated below, and any necessary construc-
tion or acquisi tion shall begin wi thin two and one-half years of
the effective date of this Plan, except as otherwise indicated.
1. Police Protection. Police protection for the
Tract can be provided by using existing capital improvements. Addi-
tional capital improvements are not necessary at this time to provide
police protection to the Tract. However, the Tract will be included
with other territory in connection with planning for new, revised or
expanded police facilities.
2. Fire Protection. Fire protection for the Tract
can be provided by using existing capital improvements. Additional
capital improvements are not necessary at this time to provide fire
protection to the Tract. However, the Tract will be included wi th other

the City's practices and are beneficial in integrating the area into
the City's water and wastewater systems~
, c. expedite the approval of plans and bond
applications in order to meet the time constraints imposed by annex-
ation and the dissolution of the districts~
d. allow the districts' residents and pro-
perty owners, who have or would have contributed to the retirement
of district bonds prior to annexation, a reasonable opportunity to
obtain the use of utility capacity if the districts' bond funds have
been used to pay for such capacity~ and
e. expend unobligated proceeds of the dis-
tricts' bonds for projects which are consistent with the purposes for
which the proceeds may be lawfully used, which may include providing
water, wastewater or drainage services for residents and properties
wi thin the boundaries of the annexed districts, such projects to be
undertaken in a timely manner.
5. Roads and Streets (including lighting). In
general, the City will acquire dominion, control, and' jurisdiction
in, ove r and under public roads and streets wi thin the Tract upon
annexation, pursuant to art. 1175, V.A.T.S., and similar provisions,
subject to' the jurisdictions of other governmental entities. Addi-
tional roads, streets or related facilities are not necessary at
this time to serve the Tract. Future extensions of roads or streets
and future installation of related facilities such as traffic control
devices or street lights will be governed by standard policies and
procedures. The Tract will be included with other territory in
connection with planning for new, revised, widened or enlarged roads,
streets or related facilities.
. 6. Parks, Playgrounds and Swimming Pools. These
services can be provided by using existing capital improvements.

SUBJECT:
Sewage Treatment Plant Improvements - Waste Sludge Pump Station
The sludge transfer problem between the digester and thickener has continued
to the point of slowing process operations at the treatment facility. Too
much valuable time is expended attempting to keep the existing transfer
piping unplugged. I recommend that we carry forward the advise of the
engineers from Turner, Collier and Braden as soon as possible.
According to Bob Reach, P.E., the cost estimate for the recommended sludge
pump station is $29,900. Plans and specifications for the project have
been completed. Please forward this for council approval to expend the
necessary Water/Wastewater Contingency Funds.
Please call if you need additional information.

Re: Wastewater Treatment Plant
Engineering Analysis
Turner Collie & Braden Job No. 13-02000-003
Dear Mr. Hodge,
In accordance with your letter of authorization dated June 21, 1983
to perform detailed hydraulic and mechanical analyses of several
problem~ at the wastewater treatment plant, we have completed our
evaluation and are presenting our findings and recommendations in
this letter report. We plan to meet with you on Tuesday, August 2
to present this report and discuss our recommendations.
1. HEADWORKS - confirm adequacy of l8-inch sluice gate for bypass
of aerated grit chamber
.'
we~ave analyzed the hydraulics of the bypass channel in the
headworks based on the following assumptions.
a. future average daily flow = 3.75 mgd
b. future peak flow = 2.5 times ADF = 9.375 mgd
c. return sludge flow rate = 3.75 mgd
d. five remaining gates in headworks (one at entrance to
grit chamber, two in each of the two bar screen
channels) are changed from l8-inch square sluice
gates to 36-inch wide full height openings with
slide gates
At the future average daily flow rate of 3.75 mgd and with
the five other gates modified as described above, our cal-
culations indicate that the maximum water surface elevation
in the head~orks will be 24.35 if the grit chamber is out of
service arid all the flow is being bypassed. With the top of
wall elevation of 27.00, there will be 2.65 feet of freeboard
under average daily flow conditions. We consider this to be
acceptable.

At the peak flow rate of 9.375 mgd, the maximum water surface
elevation in the headworks will be 25.52 under the bypass
.
condition. This will result in a freeboard of 1.48 feet,
which we also consider acceptable.
Our conclusion is that the l8-inch sluice gate in the bypass
channel is adequate if the remaining gates are modified to
a 3G-inch width. During periods when the grit chamber is
out of service for cleaning or maintenance, the raw sewage pump
station pumps should be controlled so that the flow rate from
the station does not exceed the design peak flow of 9.375 mgd
(G,500 gpm). The l8-inch sluice gate in the headworks bypass
channel is adequate and we recommend that no modifications be
made to that gate.
2. WASTE SLUDGE PIPING - check hydraulics of piping system for
transfer of waste sludge between the digester and the thickener
There have been a series of problems with clogging of the waste
sludge transfer pipe between the digester and thickener. The
pip~ is 8-inch diameter. There is over 200 feet of pipe
bet.een the thickener and the digester, and over 350 feet of
equivalent length including fittings. The waste sludge is not
pumped from the digester to the thickener. The difference in
water surface elevations between the digester and the thickener
provides the head to overcome friction loss and cause the
sludge to flow to the thickener.
We have analyzed the hydraulics of this piping system for a
wide range of possible operating conditions. Our analysis
indicates that the probable waste sludge flow rate in this
pipe is 150 to 200 gpm, with a corresponding range of velocity
of 0.96 to 1.28 feet per second in the pipe during wasting
periods. Since the wasting operation should not be continuous,
ther~ should be no flow at times during the day. In fact,
the wasting period should not exceed 2.5 hours at the current
plant design rate and 3.8 hours at the future design rate.
Under the -most favorable operating conditions, our analysis
shows that the sludge flow rate will be approximately 300 gpm
during wasting periods, with a corresponding velocity of
1.91 feet per second.

The probable rate of flow in this pipeline is not high
enough to prevent settling of solids in this pipe, even
during wasting periods. Most of the time the rate of
flow will be zero, which will allow further deposition
of solids and will increase the potential for the pipe
to clog.

ou~'recommendations for operational procedures to minimize
thi~ problem are as follows.
a. Thoroughly clean the piping system.
b. Maintain the water surface elevation in the thickener
below the overflow weir, at or slightly above the
point of discharge in the center feed pipe. This
will require the operators to pump out or siphon the
supernatant, or else will require modifications to
the overflow trough and piping.
c. Maintain the water surface elevation in the digester
at the maximum practical elevation (approximately
elevation 23.19). .
d. Minimize the wasting period so! as to maximize the
~waste sludge flow rate and velocity. Do not attempt
to waste continuously or for extended periOdS of time.
Flush. the sludge piping with process water after each
wasting period.

In the long run, the most practical solution is waste
sludge pumps, and we recommend they be installed as soon
as possible. On an interim basis, a single pump.in a
temporary installation would be an improvement over the
existing condition.
3. GRIT HANDLING EQUIPMENT - check hydraulics and mechanical
equipment design for the grit pumP. cyclone. and classifier
system
There have been problems at the plant with overflow of the
grit classifier hopper after periods of grit pumping. From
. the grit chamber, there is a single 6-inch suction pipe
which splits to two 4-inch suction lines feeding the two
grit pumps. The grit pump discharge lines connect into a
common pipe which feeds the grit cyclone. The cyclone
overflow is piped to a drain line and into the plant sewers.
The underflow feeds dir~ctly to the grit classifier. The
classifier overflow is also piPced to the drain line and
into the plant sewer.
We.have evaluated the hydraulic and mechanical design of
this system and have found it to be satisfactory. There
is-no apparent design problem which would cause overflow
of the classifier hopper. The pump suction, pump discharge
and drain piping are all adequately sized. The grit pump,
grit cyclone and the grit classifier are properly sized
and matched in capacity. We have considered a range of
possible operating conditions and have not identified any
design problems at any point in the possible range of
operation. .
There are several possible explanations of the cause of
the problem. The drain piping may be clogged or obstructed.
The equipment furnished may not be in accordance with the
spe9ifications and approved shop drawings; i.e. wrong pump
size, wrong pump speed, wrong impeller, undersized cyclone,
undersized classifier, etc., or the equipment may be mal-
functioning1 i.e. cyclone is clogged, classifier overflow
is clogged or obstructed, etc.

Page Five
To deter.mine the cause of this problem, we recommend the
following course of action. .
a. Check all drain piping for obstruction or blockages,
including the cyclone overflow, classifer overflow
and the drain line to the plant sewer manhole. Clean
and flush all lines and establish that they are
flowing freely.
b. Check the cyclone and classifier overflows and pipe
connections for obstructions.
c. Check pump speed to deter.mine if it is in range
(approximately 700 rpm).
d. Check pump discharge pressure to deter.mine if it is
in range (8-12 psig).
e. '"If possible, check the pump discharge flow rate.
This can be done with a portable sonic type flow meter,
if one is available. Flow rate should be 150-250 gpm.
If everything appears to be in proper operating condition
and the problem is still unsolved, we recommend that the
shaaves on the grit pump be modified t.o lower the grit
slJrry flow rate to a point where overflow of the classifier
no 'ionger occurs.
4. ELECTRICAL SWITCHGEAR ROOM - evaluate the electrical switch-
gear room heat and ventilation requirements
There has been a series of problems with overheating of
motor starters, particularly those for the rotor drives,
in the electrical switchgear room of the operations building.
The electrical switchgear room is located at the south end
of the operations building. The switchgear is contained in
a room with dimensions of 30 feet by lG feet. Most of this
area is used for storage. The space is not air conditioned
and does not have any exhaust fans, openings, louvers or
other such methods of ventilation.

The switchgear contained in the room includes a 37.5 KVA
transformer, a 75 KVAR capacitor, the main distribution
panelboard, motor control center A and the main fighting
panel. Motor control center A contains a 15 KVA trans-
former, four size 4 motor starters, twelve size 2 motor
starters, and some smaller equipment. Four size 2 motor
starters are proposed to be added in the future.
We have calculated a heat gain of 12,200 BTUH in the
electrical switchgear room due to the equipment contained
in this area. when the outdoor ambient temperatures are
high, the heat gain in the switchgear room is enough to
cause thermal overloading of the motor starters in motor
control center A. Unless the heat generated by the switch-
gear is ventilated, it can be expected that there will be
some problems with nuisance tripping during summer months
or unusually hot days. In order to prevent this problem,
it will be necessary to provide same form of positive
ventilation for the switchgear room.
We have checked the existing air conditioning unit for the
op~rations building to determine if it would be possible
to~dd the electrical switchgear room to the system.
Unf~rtunately, the addition of the calculated heat gain to
the existing air conditioning load would create a total
heat gain that exceeds the capacity of the system by 27
percent. Therefore, this is not a viable solution.
We have evaluated two other possible solutions. The first
solution would be to seal the wall between the storage and
switchgear areas, louver the exterior doors and install a
2300 cfm roof mounted exhaust fan. The second solution
would be to install two 2300 cfm roof mounted exhaust fans
and replace two of the windows in the storage room with
louvers. In either case, the fans should be two-speed
with double set-point thermostat control.
We recommend that the second solution be implemented,
i.e. install two roof-mounted exhaust fans. This will
permit ventilation of the storage area as well as the
switchgear room, and will have the added benefit of

providing some amount of backup in the event that one
fan breaks down. As an interim measure, we woulq
recommend that the exterior doors be left open on hot
days and portable fans be used to ventilate the area.
This completes the work authorized by your June 21, 1983 letter.
We would be pleased to meet with you to discuss our analyses and
recommendations. If you have any questions or require any

SUBJECT:
Budget
On October 1, the 198 -84 budget for the City of La Porte went into effect.
Three areas of this budget contain funds for street paving. The General
Fund Budget includes $246,935 for street maintenance. The Capital Improvement
Budget includes $450,000 for reconstruction of streets, and $69,810 for
improvement of Coupland Drive. The Revenue Sharing budget includes $150,000
for street repair, material only.
The General Fund budget will be used for maintenance purposes, and could
include some reconstruction. The Capital Improvement Budget will be used
for reconstruction, and could include some new construction of unpaved streets.
Revenue sharing will be used for construction of unpaved streets, using force
account labor.
With $150,000 in Revenue Sharing, eight (8) unpaved streets can be constructed
this year. Per priority, determined by Council, these streets include Lemon
Lane, N. "p" St. east of 26th, Willowview, Battleview, East Plainbrook, Easy St.,
Mossy St., and Flintrock.
If Council determines that the City will pave unimproved commercial streets,
$100,000 can be used from the Capital improvement budget. Designed with 28
foot wide stabilized subgrade, 26 foot wide rock base 8 inches deep, and 26
foot wide asphalt surface 2 inches deep, approximately 7,000 square yards can
be paved, using contract prices obtained from the last Lomax street project.
Council will set priorities for paving commercial streets if the project is
approved.
If you should have any question, please advise.

Mr. Ed Wolf

Dear Mr. Wolf:
This letter is to confirm the arrangements City Council made with you
concerning the repair of your house in the 100 block of North Third
street (block 57, lots 31-33, La Porte).
Council has granted thirty (30) days for all permits for repair of the
house to be issued. This thirty day period will run through Oct. 21, 1983.
One hundred and twenty (120) days have been granted to complete repairs to
the house. This period will be figured from October 21, 1983 and will run
through January 18, 1984.
Repairs to the house must include structural, electrical, and plumbing.
The house must, in all regards, be brought to the standards set in the
1982 Standard Housing Code. You may, of course, do all structural work
yourself,- however, all electrical or plumbing work must be done by
licensed, bonded contractors.
Enclosed are lists of all currently bonded contractors which you may find
useful. I am not requiring, or recommending, any particular contractor.
All listed contractors may pull permits. In addition, I have enclosed a
"Tips for Builders" booklet. This booklet will cover plan requirements
as well as inspection scedules.
If you have any questions, please contact me at 471-5020, extension 2 4,
or City of La Porte, P. O. Box 1115, La Porte, TX 77571 to my attention.
Thank you for your cooperation in this matter.

INTER-OFFICE MEMORANDUM
TO:
DATE: 10/11/83
David A. Pauli~~.
FROM: Mark s. Lew~V
SUBJECT: Ed Wolf's house 100 Block N 3rd
City Council, in the September 21, 1983 Public Hearin& granted Mr. Ed Wolfl
30 days (from September 21, 1983) to pull permits; and 120 days (from
October 21, 1983) to repair his house located in the 100 block of North 3rd
Street (legal description lot 31-33, block 57). The morning after the
Council meeting I sent Mr. Wolf the enclosed letter specifying the repairs
the house requires and the time period allotted to complete tnem.
After receiving the letter, Mr. Wolf contacted the Inspection Department by
phone. He said he wanted to reboard the house, close the openings around the
botto~ and not do any other repairs as the house is to be used strictly for
personal storage and will not be occupied.
Section 8-122 The City's Dangerous Building Ordinance (#1145) specifies --
"the order shall further require, as the facts may justify, that the Owner
shall either repair such building in compliance with the Building Code of
the City"- -. In addition during the public hearing, we (you and I) specified
that all repairs must meet housing code standards. When Mayor Cline called for
the vote on whether or not to allow Mr. Wolf to repair the house, she specified
that the repairs must be to all applicable code standards.
I believe we are on solid ground with the Dangerous Building Ordinance if we
require the house to be completely repaired and brought to Housing Code Standards.
However, all of Council's instructions to Mr. Wolf and the Board of Inspections
were verbal. This has apparantly left room for some misunderstanding on Mr.
Wolf's part as to the extent of the repairs that must be made to the house.
To clarify the misunderstanding, I recommend we approach Council and request
a clarification as to their intent. We should also request written copies of
their decision for both Mr. Wolf and ourselves.
If Council should decide that securing the house is adequate, we should have
a set of "board up" specifications ready. We should, again, request written
copies of the decision and make sure the "board up" specifications are included.
Finally we should set up a procedure where all of Council's decisions on
dangerous buildings are issued in writing.

RE: 1983 Annexations
Dear Jack:
In connection wi th the proposed 1983 Annexations of Spenwick
Place Municipal Utili ty District; College View Municipal
Util i ty District; and the acreage lying between said Util i ty
Districts, I enclose herewith draft of a proposed Service
Plan, which must be presented an explained to those attending
the Public Hearing on November 9, 1983, and which thereafter
is attached to the Final Annexation Ordinance as an Exhibi t,
and becomes a binding contract between the Ci ty and the resi-
dents of the annexed area.
Please examine carefully, review
heads, and give me your comments
additions, in time for preparation
bution at the Public Hearing.
wi th appropriate department
for necessary deletions or
of a final draft for distri-
Jack, for the submission to the United States Justice
Department under the Voting Rights Act, we will need a demo-
graphic census of the area proposed to be annexed. I believe we
could use 1980 census official figures, if we can correlate the
census tracts to the tracts to be annexed. I bel ieve a census
of the entire tract, taken as a whole, will be suff icient for
our purposes at this time. The census should be broken down
between Caucasian, Mexican-American, Black, Orientals and other
minority populations. Next, I think it would be helpful to
submit figures on our estimate of the population of the City of
La Porte as of October 1, 1983. This could be done by taking

the 1980 census and adding the building permi ts which have been
issued since that date, with our estimate of the number of people
residing in each of the houses which have since been constructed.
If this could be done by counc il district, I think it would be
helpful, so that we can demonstrate to the Justice Department
the large amount of growth which has occurred, and which will
continue to occur, in the Western area of the City.
Finally, I need a map to submi t to the Justice Department, wi th
about six (6) copies, colored to show the existing six council
districts, together wi th the proposed annexation tract shown in
a different color. I would like to have the information for
the Justice Department within the next thirty (30) days, to
expedite the filing of the Application, as the Justice Department
has sixty (60) days from the filing of the Application to rule
on it, and may ask for an additional thirty (30) days' extension.
We need to time the Justice Department filing so as to hopefully
have a final ruling from them prior to the filing deadline for
candidates for office in the April, 1984 elections.

[The Following is Exhibit A]
SERVICE PLAN
FOR
A TRACT OF LAND COMPRISING
THE SPENWICK PLACE MUNICIPAL UTILITY DISTRICT~
THE COLLEGE VIEW MUNICIPAL UTILITY DISTRICT~
AND THE ACREAGE LYING BETWEEN SAID UTILITY DISTRICTS~
INTRODUCTION
This Service Plan (IfPlanlf) is made by the City of La Porte,
Texas (IfCitylf) pursuant to Section lO of the Municipal Annexation Act
art. 970a, V.A.T.S., (Vernon's Supp. 1982) (the IfActlf). This Plan
relates to the annexation by the City of a tract of land (IfTractlf) com-
prising the Spenwick Place Municipal Utility District~ the College View
Municipal Utility District~ and the acreage lying between said utility
districts. The Tract is described by metes and bounds in If Exhibit B"
which is attached to this Plan and to the annexation ordinance of which
this Plan is a part.
II. TERM~ EFFECTIVE DATE
This Plan shall be in effect for a term of ten years commencing
on the effective date of the annexation of the Tract. Renewal of this
Plan shall be at the option of the City. Such option may be exercised
by the adoption of an ordinance by the City Council which refers to this
Plan and specifically renews this Plan for' a stated period of time.
III. SERVICE PROGRAMS
A. In General. This Plan includes two service programs:
(i) the Early Action Program, described below, and (ii) a Capital
Improvement Program, described below.
B. Scope and Quality of Services. Services under this Plan
shall equal or exceed the number of services and the level of services
in existence in the Tract prior to annexation. However, it is not the
intent of this Plan to require that a uniform level of services be pro-
vided to all areas of the City (including the Tract) where differing
characteristics of topography, land utilization and population density
are considered as sufficient basis for providing differing service
leve ls.
C.
I.
Definitions.
1. As used in this Plan, providing services in-
cludes having services provided by any method or means by which the
Ci ty extends munic ipal services to any other area of the City. This
may include causing or allowing private utilities, governmental
entities and other public service organizations to provide such
services, in whole or in part.
2. As used in this Plan, the phrase Ifstandard pol-
icies and procedureslf means those policies and procedures of the
City applicable to a particular service which are in effect either
at the time that the service is requested or at the time that the
service is made available or provided. The policies and procedures
may require that a specific type of request be made, such as an
application or a petition. They may require that fees or charges
be paid, and they may include eligibility requirements and similar
provisions.
D.
Early Action Program.
1. Statutory Services. The statutory services will
be provided within the Tract within sixty days after the effective
date of this Plan, except as otherwise indicated. The statutory
services are as follows:
a. Police Protection. The Police Department
of the City will provide protection and law enforcement in the Tract.
These activities will include normal patrols and responses, the
handling of complaints and incident reports, and other usual and
customary police services.
f3~
e
e
b. Fire Protection. The Fire Department of
the City will provide fire protection in the Tract.
c. Solid Waste Collection. Residential col-
lection services will be provided by City forces. Non-residential
service and future residential service will be governed by standard
policies and procedures.
d. Maintenance of Water and Wastewater Faci-
lities. Those water and wastewater facilities included in the
Capital Improvement Program, below, will be maintained by an appro-
priate division of the Department of Public Works or, for a 1 imi ted
period of time, by a conservation and reclamation district which is
to be dissolved. Should any exte~sions of such fac i 1 i ties be made
within the Tract, normal maintenance services will be provided.
e. Maintenance of Roads and Streets (includ-
ing lighting). The Department of Public Works will provide mainte-
nance of roads and streets over which the Ci ty will have jurisdic-
tion. (See Capital Improvement Program, below). The City of La
Porte will provide services relating to traffic control devices for
such roads and streets, and will provide street lighting for such
roads and streets through the Houston Lighting and Power Company or
by other means.
f. Maintenance of Parks, Playgrounds and
Swimming Pools. As indicated by the Capital Improvement Program, it
is not necessary to acquire or construct such facilities in the Tract,
so there are none to be maintained. Should any such facil i ties be
constructed by the City within the Tract, the Department of Parks and
Recreation will provide maintenance services for them.
g. Maintenance of Any Other Publicly-owned
Facility, Building or Service. Those drainage facilities included in
the Capital Improvement Program, below, will be maintained by the
Department of Public Works, as needed. Should any such facilities,
buildings or services be constructed or located by the City within the
Tract, an appropriate Ci ty department will provide maintenance services
for them.
2. Additional Services. Certain services, in addi-
tion to the statutory services, will be provided within the Tract to
the same extent they are provided to similar territories elsewhere
in the City. These are as follows:
a. Library services from existing facilities
and future facilities outside the Tract.
b. Health Services in accordance with stan-

SUBJECT:
Sewage Treatment Plant Improvements - Waste Sludge Pump Station
The sludge transfer problem between the digester and thickener has continued
to the point of slowing process operations at the treatment facility. Too
much valuable time is expended attempting to keep the existing transfer
piping unplugged. I recommend that we carry forward the advise of the
engineers from Turner, Collier and Braden as soon as possible.
According to Bob Reach, P.E., the cost estimate fo~ the recommended sludge
pump station is $29,900. Plans and specifications for the project have
been completed. Please forward this for council approval to expend the
necessary Water/Wastewater Contingency Funds.

Re: Wastewater Treatment Plant
Engineering Analysis
Turner Collie & Braden Job No. 13-02000-003
Dear Mr. Hodge,
In accordance with your letter of authorization dated June 21, 1983
to perform detailed hydraulic and mechanical analyses of several
problem~ at the wastewater treatment plant, we have completed our
evaluation and are presenting our findings and recommendations in
this letter report. We plan to meet with you on Tuesday, August 2
to present this report and discuss our recommendations.
1. HEADWORKS - confirm adequacy of l8-inch sluice gate for bypass
of aerated grit chamber
~'
WeiQve analyzed the hydraulics of the bypass channel in the
headworks based on the following assumptions.
a. future average daily flow = 3.75 mgd
b. future peak flow = 2.5 times ADF = 9.375 mgd
c. return sludge flow rate = 3.75 mgd
d. five remaining gates in headworks (one at entrance to
grit chamber, two in each of the two bar screen
channels) are changed from l8-inch square sluice
gates to 36-inch wide full height openings with
slide gates
At the future average daily flow rate of 3.75 mgd and with
the five other gates modified as described above, our cal-
culations indicate that the maximum water surface elevation
in the headworks will be 24.35 if the grit chamber is out of
service arid all the flow is being bypassed. With the top of
wall elevation of 27.00, there will be 2.65 feet of freeboard
under average daily flow conditions. We consider this to be
acceptable.

At the peak flow rate of 9.375 mgd, the maximum water surface
elevation in the headworks will be 25.52 under the bypass
condition. This will result in a freeboard of 1.48 feet,
which we also consider acceptable.
Our conclusion is that the l8-inch sluice gate in the bypass
channel is adequate if the remaining gates are modified to
a 36-inch width. During periods when the grit chamber is
out of service for cleaning or maintenance, the raw sewage pump
station pumps should be controlled so that the flow rate from
the station does not exceed the design peak flow of 9.375 mgd
(6,500 gpm). The l8-inch sluice gate in the headworks bypass
channel is adequate and we recommend that no modifications be
made to that gate.
2. WASTE SLUDGE PIPING - check hydraulics of p~p~ng system for
transfer of waste sludge between the digester and the thickener
There have been a series of problems with Clogging of the waste
sludge transfer pipe between the digester and thickener. The
pip~. is 8-inch diameter. There is over 200 feet of pipe
bet~een the thickener and the digester, and over 350 feet of
equivalent length including fittings. The waste sludge is not
pumped from the digester to the thickener. The difference in
water surface elevations between the digester and the thickener
provides the head to overcome friction loss and cause the
sludge to flow to the thickener.
We have analyzed the hydraulics of this piping system for a
wide range of possible operating conditions. Our analysis
indicates that the probable waste sludge flow rate in this
pipe is 150 to 200 gpm, with a corresponding range of velocity
of 0.96 to l.28 feet per second in the pipe during wasting
periods. Since the wasting operation should not be continuous,
ther~ should be no flow at times during the day. In fact,
the wasting period should not exceed 2.5 hours at the current
plant design rate and 3.8 hours at the future design rate.
Under the most favorable operating conditions, our analysis
shows that the sludge flow rate will be approximately 300 gpm
during wasting periods, with a corresponding velocity of
1.91 feet per second.

The probable rate of flow in this pipeline is not high
enough to prevent settling of solids in this pipe, even
during wasting periods. Most of the time the rate of
flow will be zero, which will allow further deposition
of solids and will increase the potential for the pipe
to clog.

;pr()vided.~f OUr conclusion ,,'fsthat the"arrangement of the
structures and the piping system is very likely to con-
triQute to the pipe clogging and may be totally responsible
for the problem. This problem could have been minimized or
eliminated by locating the structures closer together,
increasing the difference in water surface elevations,

Ou~.recommendations for operational procedures to minimize
tht~ problem are as follows.
a. Thoroughly clean the piping system.
b. Maintain the water surface elevation in the thickener
below the overflow weir, at or slightly above the
point of discharge in the center feed pipe. This
will require the operators to pump out or siphon the
supernatant, or else will require modifications to
the overflow trough and piping.
c. Maintain the water surface elevation in the digester
at the maximum practical elevation (approximately
elevation 23.19).
d. Minimize the wasting period so' as to maximize the
~waste sludge flow rate and velocity. Do not attempt
to waste continuously or for extended periods of time.
Flush the sludge piping with process water after each
wasting period.

In the long run, the most practical solution is waste
sludge pumps, and we recommend they be installed as soon
as possible. On an interim basis, a single pump.in a
temporary installation would be an improvement over the
existing condition.
3. GRIT HANDLING EQUIPMENT - check hydraulics and mechanical
equipment design for the grit pumP. cyclone. and classifier
system
There have been problems at the plant with overflow of the
grit classifier hopper after periods of grit pumping. From
. the grit chamber, there is a single 6-inch suction pipe
which splits to two 4-inch suction lines feeding the two
grit pumps. The grit pump discharge lines connect into a
common pipe which feeds the grit cyclone. The cyclone
overflow is piped to a drain line and into the plant sewers.
The underflow feeds directly to the grit classifier. The
classifier overflow is also piped to the drain line and
into the plant sewer.
We4have evaluated the hydraulic and mechanical design of
this system and have found it to be satisfactory. There
is,no apparent design problem which would cause overflow
of the classifier hopper. The pump suction, pump discharge
and drain piping are all adequately sized. The grit pump,
grit cyclone and the grit classifier are properly sized
and matched in capacity. We have considered a range of
possible operating conditions and have not identified any
design problems at any point in the possible range of
operation. .
There are several possible explanations of the cause of
the problem. The drain piping may be clogged or obstructed.
The equipment furnished may not be in accordance with the
specifications and approved shop drawings; i.e. wrong pump
size, wrong pump speed, wrong impeller, undersized cyclone,
undersized classifier, etc., or the equipment may be mal-
functioning~ i.e. cyclone is clogged, classifier overflow
is clogged or obstructed, etc.

To determine the cause of this problem, we recommend the
following course of action.
a. Check all drain piping for obstruction or blockages,
including the cyclone overflow, classifer overflow
and the drain line to the plant sewer manhole. Clean
and flush all lines and establish that they are
flowing freely.
b. Check the cyclone and classifier overflows and pipe
connections for obstructions.
c. Check pump speed to determine if it is in range
(approximately 700 rpm).
d. Check pump discharge pressure to determine if it is
in range (8-12 psig).
e. "If possible, check the pump discharge flow rate.
This can be done with a portable sonic type flow meter,
if one is available. Flow rate should be 150-250 gpm.
I.f everything appears to be in proper operating condition
and the problem is still unsolved, we recommend that the
sheaves on the grit pump be modified to lower the grit
sldrry flow rate to a point where overflow of the classifier
no 'ionger occurs.
4. ELECTRICAL SWITCHGEAR ROOM - evaluate the electrical switch-
gear room heat and ventilation requirements
There has been a series of problems with overheating of
motor starters, particularly those for the rotor drives,
in the electrical switchgear room of the operations building.
The electrical switchgear room is 10cated at the south end
of the operations building. The switchgear is contained in
a room with dimensions of 30 feet by 16 feet. Most of this
area is used for storage. The space is not air conditioned
and does not have any exhaust fans, openings, louvers or
other such methods of ventilation.

The switchgear contained in the room includes a 37.5 KVA
transformer, a 75 KVAR capacitor, the main distribution
panelboard, motor control center A and the main tighting
panel. Motor control center A contains a 15 KVA trans-
former, four size 4 motor starters, twelve size 2 motor
starters, and some smaller equipment. Four size 2 motor
starters are proposed to be added in the future.
We have calculated a heat gain of 12,200 BTUH in the
electrical switchgear room due to the equipment contained
in this area. When the outdoor ambient temperatures are
high, the heat gain in the switchgear room is enough to
cause thermal overloading of the motor starters in motor
control center A. Unless the heat generated by the switch-
gear is ventilated, it can be expected that there will be
some problems with nuisance tripping during summer months
or unusually hot days. In order to prevent this problem,
it will be necessary to provide some form of positive
~entilation for the switchgear room.
We have checked the existing air conditioning unit for the
op~rations building to determine if it would be possible
to~dd the electrical switchgear room to the system.
Unf~rtunately, the addition of the calculated heat gain to
the existing air conditioning load would create a total
heat gain that exceeds the capacity of the system by 27
percent. Therefore, this is not a viable solution.
We have evaluated two other possible solutions. The first
solution would be to seal the wall between the storage and
switchgear areas, louver the exterior doors and install a
2300 cfm roof mounted exhaust fan. The second solution
would be to install two 2300 cfm roof mounted exhaust fans
and replace two of the windows in the storage room with
louvers. In either case, the fans should be two-speed
with double set-point thermostat control.
We recommend that the second solution be implemented,
i.e. install two roof-mounted exhaust fans. This will
permit ventilation of the storage area as well as the
switchgear room, and will have the added benefit of

providing some amount of backup in the event that one
fan breaks down. As an interim measure, we woulq
recommend that the exterior doors be left open on hot
days and portable fans be used to ventilate the area.

On October 1, the 1983-84 budget for the City of La Porte went into effect.
Three areas of this budget contain funds for street paving. The General
Fund Budget includes $246,935 for street maintenance. The Capital Improvement
Budget includes $450,000 for reconstruction of streets, and $69,810 for
improvement of Coupland Drive. The Revenue Sharing budget includes $150,000
for street repair, material only.

SUBJECT:
The General Fund budget will be used for maintenance purposes, and could
include some reconstruction. The Capital Improvement Budget will be used
for reconstruction, and could include some new construction of unpaved streets.
Revenue sharing will be used for construction of unpaved streets, using force
account labor.
With $150,000 in Revenue Sharing, eight (8) unpaved streets can be constructed
this year. Per priority, determined by Council, these streets include Lemon
Lane, N. "p" St. east of 26th, Willowview, Battleview, East Plainbrook, Easy St.,
Mossy St., and Flintrock.
If Council determines that the City will pave unimproved commercial streets,
$100,000 can be used from the Capital improvement budget. Designed with 28
foot wide stabilized subgrade, 26 foot wide rock base 8 inches deep, and 26
foot wide asphalt surface 2 inches deep, approximately 7,000 square yards can
be paved, using contract prices obtained from the last Lomax street project.
Council will set priorities for paving commercial streets if the project is
approved.
If you should have any question, please advise.

LA PORTE. TEXAS 77571
September 23, 1983
Mr. Ed Wolf
811 Bayshore Drive
La Porte, TX 77571
Dear Mr. Wolf:
This letter is to confirm the arrangements City Council made with you
concerning the repair of your house in the 100 block of North Third
street (block 57, lots 3l-33, La Porte).
Council has granted thirty (30) days for all permits for repair of the
house to be issued. This thirty day period will run through Oct. 21, 1983.
One hundred and twenty (120) days have been granted to complete repairs to
the house. This period will be figured from October 21, 1983 and will run
through January 18, 1984.
Repairs to the house must include structural, electrical, and plumbing.
The house must, in all regards, be brought to the standards set in the
1982 Standard Housing Code. You may, of course, do all structural work
yourself,- however, all electrical or plumbing work must be done by
licensed; bonded contractors.
Enclosed are lists of all currently bonded contractors which you may find
useful. I am not requiring, or recommending, any particular contractor.
All listed contractors may pull permits. In addition, I have enclosed a
"Tips for Builders" booklet. This booklet will cover plan requirements
as well as inspection scedules.
If you have any questions, please contact me at 471-5020, extension 2 4,
or City of La Porte, P. O. Box 1115, La Porte, TX 77571 to my attention.
Thank you for your cooperation in this matter.
Sincerely,
4-<~

INTER-OFFICE MEMORAND~1
TO:
DATE: 10/11/83
FROM:
David A. pauli~~f
Mark S. LewA'V
SUBJECT: Ed Wolf's house 100 Block N 3rd
City Council, in the September 21, 1983 Public Hearing granted Mr. Ed Wolf
30 days (from September 21, 1983) to pull permits; and 120 days (from
October 21, 1983) to repair his house located in the 100 block of North 3rd
Street (legal description lot 31-33, block 57). The morning after the
Council meeting I sent Mr. Wolf the enclosed letter specifying the repairs
the house requires and the time period allotted to complete tpem.
After receiving the letter, Mr. Wolf contacted the Inspection Department by
phone. He said he wanted to reboard the house, close the openings around the
botto~ and not do any other repairs as the house is to be used strictly for
personal storage and will not be occupied. .
Section 8-122 The City's Dangerous Building Ordinance (#1145) specifies --
"the order shall further require, as the facts may justify, that the Owner
shall either repair such building in compliance with the Building Code of
the City"- -. In addition during the public hearing, we (you and I) specified
that all repairs must meet housing code standards. When Mayor Cline called for
the vote on whether or not to allow Mr. Wolf to repair the house, she specified
that the repairs must be to all applicable code standards.
I believe we are on solid ground with the Dangerous Building Ordinance if we
require the house to be completely repaired and brought to Housing Code Standards.
However, all of Council's instructions to Mr. Wolf and the Board of Inspections
were verbal. This has apparantly left rqom for some misunderstanding on Mr.
Wolf's part as to the extent of the repairs that must be made to the house.
To clarify the misunderstanding, I recommend we approach Council and request
a clarification as to their intent. We should also request written copies of
their decision for both Mr. Wolf and ourselves.
If Council should decide that securing the house is adequate, we should have
a set of "board up" specifications ready. We should, again, request written
copies of the decision and make sure the "board up" specifications are included.
Finally we should set up a procedure where all of Council's decisions on
dangerous buildings are issued in writing.
