SUMMARY & RECOMMENDATION
City Council, at the January 26, 2009 meeting, authorized the City Manager to proceed with
twelve (12) projects identified by the recently completed Drainage Master Plan. Two of the
Projects, Brookglen (#2) and Fairmont East (#8) are of sufficient complexity to require outside
engineering services. Additionally, other factors affecting drainage in these areas warrant
additional detailed study. Klotz and Associates was requested to provide a proposal to perform
the following:
. Identify and design sheet flow relief swales and, if needed, increases in outfall pipe sizes
and inlets.
. Provide necessary surveying and produce plans and specifications for bidding.
. Additional services to include a storm sewer analysis on the existing storm sewer system
for Fairmont Park East and develop three (3) alternatives.
. Additional services to include investigation of the Brookglen Subdivision to judge the
impacts ofreconfiguring the confluence ofB112-02 and BI12-00 to reduce backwater
buildup in B 112-02.
Additionally, staff has request Klotz and Associates to provide a proposal to design
improvements in Fairmont Park West (#3) and Creekmont (#7) to provide a reliefpipe(s) for
areas identified in the Master Plan. Staff will return to Council with this proposal for
a . ation, when received.

Re: Scope of Work and Budget for Constructing Sheet Flow Relief Structures
in Brookglen & Fainnont Park East Subdivisions
Klotz Associates Proje(:t No. 0127.009.000
Dear Mr. Bottoms:
As requested, submitted herein is the proposal for professional engineering services for design
and preparation of bid ready documents for the construction of sheet flow relief swales and storm
sewer outfall improvements for Fairmont Park East and Brookglen Subdivisions. These services
will be perfonned under the proposed attached General Services Agreement (we will send our
one page agreement for these services to you when the scope is agreed upon).
UNDERSTANDING OF THE PROJECT
Brookglen drainage and sheet flow drain naturally toward HCFCD Unit B 112-00-00 from the
east and west, and toward. Unit B 112-02-00 from the north and south. Sheet flow collects in the
low lying areas that cause flooding to occur for events more frequent than the 1 DO-year storm
even. Floodwater from these areas cannot escape, resulting in repetitive losses for home owners
who are not in the 1 OO~year flood plain. Excess runoff is stored in the streets and cannot flow
out until the storm sewers empty. To solve this problem, sheet flow relief swales are proposed in
the lower areas, and for higher elevations increasing storm sewer pipe sizes and adding inlets are
proposed to be constructed between HCFCD Unit B112-00-00 and Bandridge Road, between
HCFCD Unit B112-02-00 and roadways Bandridge Road and Gladwyne Lane.
Fairmont Park East experiences a similar drainage problem. During the preliminary engineering
phase, a brief stonn sewer capacity analysis will be performed to detennine the level of
protection the existing system provides. Proposed improvements for these areas may require a
combination of sheet flow relief swales with increases in pipe size and inlets. Fairmant Park
East drains toward HCFCD Unit's B106-00-00 and Unit B106-02-00 from the north and the
south.
Klotz Associates will develop an economic solution and identify locations which can be
constructed by City personnel quickly, if the City chose this option over the bid process. Klotz

Associates meet with City staff to present our findings and prepare. a construction cost estimate,
list of bid items and specifications used and layouts for approval of the drainage and relief swale
alignments chose. Design plans and specifications are part of this scope of work. Listed herein
is the proposed scope of basic services for Brookglen and Fairmont Park East drainage and sheet
flow relief swales.
As part ofthis agreement, Klotz Associates will perform additional services for the City. The
purpose ofthe additional services is to perform a stonn sewer system analysis on the existing
storm sewer for Fairmont Park East Subdivision. Three (3) storm sewer systems will be
analyzed; the system draining to main trunk line along Fleetwood Drive, the system draining to
main trunk line along Driftwood Drive and the system draining to the outfall at Cottonwood
Drive and Pecan Drive. Common methods acceptable to HCFCD and the City will be used to
investigate the conveyance capacity of the existing system for stonn events up to and including
the 1 O-year and 100pyear storm events. Klotz Associates will detennine the inlet and pipe
capacities based on tailwater effects in HCFCD receiving streams for each storm event and
develop three (3) alternatives intended to decrease the frequency oflocalized street flooding
within depressed roadway sections.
As part of the additional services Klotz Associates will investigate the impacts of reconfiguring
the confluence ofHCFCD Units B112-0200 and B112-00-00 to reduce backwater buildup effects
occurring in B112-02-00 upstream of the confluence.
The results of this effort will account for the location and sizes of proposed sheet flow relief
systems from the Basic Services listed herein. A letter report will be prepared recoounending
alternatives to reduce the level of ponding in the roadways at the lowest cost possible.
SCOPE OF BASIC SERVICES
A. Project Planning and Initiation
1. Identify drainage easements and survey locations from plans provided by City Staff.
'2. Contact utility companies for locations of subsurface facilities.
3. Meet with City and County staff to coordinate design review activities.

SUMMARY & RECOMMENDATION
Summary
Per the City Wide Drainage Study prepared by Klotz & Associates, revisions to Chapter 5, Storm
Water Design of the Public Improvement Criteria Manual (PICM) were suggested. Staff presents
these suggested revisions to Council for its consideration. The key considerations are as follows:
1) Changing the design criteria for underground stonn sewers and roadside ditches from a 3-
year to a 5-year stomlfrequency.
2) Amending the required detention volwnes for 0.2 to 0.45 acre feet per acre for
developments between one and three acres.
3) Consider disallowing developments within a FEMA mapped floodway. Currently, the City
allows such development as long as a registered professional engineer prepares a No
Rise Certificate based on accepted hydraulic models.
Recommendation:
Staff is recommending amending Chapter 5 of the Public Improvement Criteria Manual to reflect
the suggested changes made by Klotz & Associates.
Action Required of Council:

CHAPTER 5
STORM WATER DESIGN CRITERIA
5.t GENERAL PROVISIONS
Drainage Criteria for development within the City of La Porte, and where applicable within La Porte's
Extraterritorial Jurisdiction (E.TJ.) is dependent upon the size and type of development, the conditions
within the individual watershed, the conditions or design of the receiving stream. bayou, channel, roadside
swale, culvell, or roadway.
The basic objective of this policy is to minimize the threat of flooding to areas within the City and its E.TJ.
and to minimize the effect of continued development on individual watersheds.
I. The City believes that the best long-term means of accomplishing its objective is a continued
program of improvement and extension of the Harris County Flood Control District's system of
open channels. This statement recognizes the technical reality that an essential prerequisite to an
effective flood control program is a system of open channels capable of carrying storm runoff of
any type in Harris County to Galveston Bay without adversely impacting existing urban areas
adjacent to the channels.
2. 'nle City recognizes that both District's and City's existing open channel system is, in many
instances, inadequate to accomplish the goal of eliminating existing flooding conditions for
existing levels of urban development, or for ultimate development in the watershed.
3. The City therefore recommends that where required, certain additional flood control facilities be
utilized to supplement the open channel system. Such flood control facilities shall be designed to
preclude flooding in areas that do not presently flood and not increase flood levels where flooding
now occurs. Specifically, the City supports the use of storm water detention to supplement the
open channel system until long-term channel improvements can be completed, or as permanent
facilities where additional open channel improvements are not feasible. The result will be that
new development will limit or restrict the impact downstream.
5.1.1 All the drainage plans and construction shall meet or exceed the requirements of the City of La
POIte, Han'is County Flood Control, Harris County. TxDOT, or any other entities having
jurisdiction over a facility (i.e. roadway, channel, etc.).
5.1.2 Unless otherwise provided for in these policies, development shall follow the Harris County Flood
Control District Criteria Manual for the design of Flood Control and Drainage Facilities in Harris
County, Texas.
5.1.3 If application of the policies and criteria contained in this document contlict with the City's duties
under the Flood Hazard Prevention Ordinance, the regulations of the Flood Hazard Prevention
Ordinance shall apply.
5.1.4 Drainage structures shall be constructed in such locations and of such size and dimensions to
adequately serve the development and the contributing drainage area. In new developments, the
developer shall provide all the necessary easements and rights-of-way required for drainage
structures, including storm sewer and open or lined channels.
5.2 CONSTRUCTION PLAN REQUIREMENTS
5.2.1 A drainage map shall be included in the construction plans. The drainage area map shall include:
Stonnwater Criteria Page 1 of 10
A. Drainage areas, including areas draining from off-site onto or adjoining the project
B. Design storm runoff, based on the type of facility and storm frequency listed in Section
5.4.
C. 100 - year runoff sheet flow pattern.
D. Route of overland flow including the overflow to a drainage channel or detention facility
E. Water surface profiles for the 25-year and/or 100-year storms in the outfall channel. All
available information will be considered when making this determination.
F. Flow per inlet
G. Maximum ponding elevation
H. For bridge designs the] OO-year WSEL must be shown on the plans and the low chord of
the bridge must be a minimum of eighteen inches above the 100-year WSEL.
5.2.2 Detailed drainage calculations shall be submitted with the construction plans.
5.2.3 A lot grading plan should demonstrate that the finished grading plan will drain to approved
collection and discharge points and that the overland flow of water from adjacent propelties will
not be impacted. A dedicated easement must be provided at the tenninus to allow the IOO-year
event to sheet flow to the ultimate outfalL In no instance will plans be approved without specific
detail as to how the I DO-year event will sheet flow from the development to the outfall without
adversely impacting structures.
5.2.4 The hydraulic gradient for the design storm may be shown on the construction drawings.
Calculations for the elevation for the hydraulic gradient shall be provided with the design storm
drainage calculations. The hydraulic gradient must be below the gutter line for the design storm.
The tail water elevations based on a 25-year frequency in the outfall channel shall be used for
calculations ofthe hydraulic gradient.
If the 25-year WSEL is not available then use 80% of the ultimate channel height. In areas which
are tidally influenced the mean high tide elevation will be used unless it is lower than the 25-year
WSEL, in which case the higher value will be used. In instances where the 25-year WSEL in the
receiving channel is lower than the top of pipe then the top of pipe shall be used as the starting
point for HGL calculations.
5.2.5 The location of detention facilities required by these standards shall generally be in the vicinity of
the lowest point of the property being developed. The city engineer has authority to make
exceptions in the event that the runoff is conveyed via underground stonn sewer facilities that
accommodate the 100-year discharge.
5.3 USE OF PREVIOUSLY DESIGNED AND INSTALLED INFRASTRUCTURE
Situations where previously installed infrastructure is in place but not yet utilized to its design
capacity will be considered on a case by case basis. The developers engineer shall after
consultation with the City, prepare a report that:
a. outline the original design criteria
b. evaluates the impact of the original design on the receiving stream, adjoining
properties and/or the 100 year Floodplain.

B. Storm Runoff
Design flow of stoon water runoff is to be calculated using the Rational Method.
The Rational Method is based on the direct relationship between rainfall and runoff, and
the method is expressed by the following equation:
Q = CIA. where
Q is the storm flow at a given point in cubic feet per second (c.[s).
C is a coefficient of runoff (see Table 1).
I is the average intensity of rainfall in inches per hour for a period equal to the
time of flow from the farthermost point of the drainage area to the point under
consideration. (See figure I, I-D-F Curves and Figure 2, Determination of Time
of Concentration)
A is the drainage area in acres
The size and shape ofthe watershed must be determined for each installation. The area
of each watershed may be detennined through the use of planimetric-topographic maps of
the area, supplemented by field surveys in areas where topographic data has changed or
where the contour interval is insufficient to adequately determine the direction of flow.
The outline of the drainage area contributing to the system being designed and outline of
the sub-drainage area contributing to each inlet point shall be determined.
When calculating the peak flow rate of storm water runoff, rainfall intensity will be
determined from the rainfall intensity, duration and frequency curves, shown in Figure 1.
The storm frequency used for this determination will be according to the facility to be
designed as listed in Section A.
I. Runoff Coefficients and Time of Concentration
Runoff coefficients, as shown in Table I, shall be the minimum used, based on
total development under existing land zoning regulations. Where land uses
other than those listed in Table I are planned, a coefficient shall be developed
utilizing values comparable to those shown. Larger coefficients may be used if
considered appropriate to the project by the City Engineer.
The time of concentration is defined as the longest time, without unreasonable
delay, that will be required for a drop of water to flow trom the upper limit of a
drainage area to the point of concentration. The time of concentration to any
point in a storm drainage system is a combination of the "inlet time" and the
time of flow in the drain. The inlet time is the time for water to flow over the
surface ofthe ground to the storm drain inlet. Because the area tributary to most
storm sewer inlets is relatively small, it is cllstomary in practice to determine the
Slonnwalcr Criteria Page 3 of 10
inlet time on the basis of experience under similar conditions. Inlet time
decreases as the slope and the imperviousness of the surface increases, and it
increases as the distance over which the water has to travel and retention by the
contact surfaces.
Time of concentration shall be computed ii'om Figure 2 and in no case shall the
inlet time be more that the time shown in Table I.

5.5.1 Design Standards for Detention Basins
Detention requirements for developments less than 50 acres shall be according to the following table. For
developed areas of 10 acres or less, the required volume equals the total development area times the
appropriate storage coefficient. For areas greater than 10 acres and less than 50 acres the volume is
determined by applying Harris County Flood Control District criteria for small watersheds.

0.45 acre ft. I acre
per HCFCD criteria
For developments which are larger than 50 acres, Harris county Flood Control District and/or the City
Engineer shall approve the detention facility criteria.
5.5.2 Outlet Sizing
I. The outlet structure shall be designed using the orifice equation as follows:
Q = CA x (2gh)"
Where,
C=0.8
A = cross sectional area

h = head differential
For head differential use 2' or the IOO-year water surface in pond minus the 25-year
water surface in receiving channel, if available.
2. Minimum restrictor shall be 6" diameter.
5.5.3 Generally accepted areas of localized runoff to roadways and the ditches adjacent to them consists of
150-ft wide strips adjacent to the roadway right-of-way on each side of the road. Drainage from beyond
this commonly accepted width zone is discouraged and should be directed to areas and/or drainage
pathways to which natural drainage occurs. If such drainage cannot be safely directed to natural drainage
pathways, on-site detention shall be required at a rate prescribed in this chapter to limit the peak rates of
discharge to an acceptable level for discharge either to the roadway or natural drainage paths. Such event is
prescribed by the design capacity of said receiving outfall.
5.5.3 Additional Standards for Detention Basins
The detention facility shall be designed for easy maintenance. For smaller developments the designer is
encouraged to use parking lots, underground piping, swales, green spaces, etc. to achieve the volume
required.
Stonnwaler Criteria Page S of 10
For larger developments every consideration shall be given to designing of the facility for multipurpose
use, such as playgrounds, ballfields, miniparks, required green spaces, etc. to assure that maintenance will
be accomplished. The design shall include the following:

of ten feet;
2. the bottom of the detention basin shall have a minimum 0.50% cross slope to facilitate quick
drainage.
3. a v-shaped trickle channel a minimum of 5' wide, six-inch thick, reinforced concrete shall be
constructed through the detention basin at a longitudinal slope 01'0.20% to accommodate low flow
and facilitate rapid drainage. For developments less than 3 acres. the trickle channel may be 2 feet
wide and 4" thick.
4. a minimum 12-foot wide maintenance beml shall be provided around the perimeter of the
detention facility.
5. ingress and egress for maintenance including a dedicated right-of-way if required. shall be
provided to the detention basin and clearly shown on the construction drawings or site plan
subdivision plat.
6. the detention basins, slopes, bottom, maintenance berm, and other associated right-of-way shall

plans.
8. Pumped detention systems may be allowed with specific approval from the City Engineer.
5.5.4 Ownership and Maintenance of Facilities
The City will not accept maintenance of on site facilities that serve only one tract or development, unless it
is determined to have other public benefits, is recommended by staff and approved by the Planning and
Zoning Commission.
Harris County Flood Control District may, at their discretion, accept maintenance of facilities, provided
they are designed in accordance with the District's criteria manual. Requests for Harris County Flood
Control District to assume maintenance of any facility should be coordinated with the City prior to any
development approvals.
5.5.5 Plat Review of Facilities
The rates of detention applicable to any development approved and authorized for construction shall be
subject to the detention rate applicable to the size tract ofland as configured on (date). As part of
the plat review process, the Planning DepaJ1ment shall utilize the configuration as shown in the Harris

SUMMARY & RECOMMENDATION
In furtherance of the La Porte Police Departments primary goal of "Providing a safe environment for the community
we serve tluough the efficient, effective, and innovative application of available police resources", the Police
Department is seeking the blessing of City Council relating to the implementation of a new K-9 program. Having a
trained and certified Police Officer/K-9 team assigned to the Department's Patrol Division would be extremely
beneficial, assisting the Patrol Division with narcotic detection as well as suspect tracking operations.
The implementation of this new program will not require any additional police resources as the officer assigned,
although competitively selected, specially trained, working with a Police Dog, and available for call-outs and special
use, will continue to work regular patrol operations, answering calls for service, etc. All other equipment and
resources necessary for program start-up, including a trained and certified narcotic detection police K-9, are being
graciously donated to the Police Department.
d b Council:
sked to give direction and their blessing regarding the establishment of a new K9 program within
e Department.

SUMMARY & RECOMMENDATION
I have completed the annual review of the employee compensation, including input from each of the department
directors (not including the police department who are engaged in Meet and Confer proceedings). The changes that
I am recommending and that have been approved by the department directors includes mainly pay grade
adjustments. However, there will still be an annual financial impact, again without including any police department
adjustments at this time) of approximately $92,000 per year - recurring, and a impact to this years budget of around
$60,000. These adjustments are based upon salary survey information that was gathered through the Human
Resources Department.

SUMMARY & RECOMMENDATION
Monday night I would like to present to council an idea for encouraging our employees to get, and more
importantly, stay in good physical condition. I believe that an employee who is physically fit is, in general terms,
more energetic, more content, more productive, and obviously healthier - reducing the demands on the city's
medical insurance (ie. cost savings). To this end, what I propose, and will go over in more detail on Monday, is that
the City provides an annual stipend to employees who meet quarterly "health" bench marks that results in meeting
an annual "health" goal. The "health" goal and quarterly bench marks will be established by a medical professional
based on an individual assessment of each participating employee. Employees participating in this program would
be required to pay a participant charge that would cover most, ifnot all, of the medical professional's fees. An
employee who meets all four quarters of bench marks and achieves the annual goal would receive the stipend. An
employee who does not meet one or more of the quarterly bench marks but still meets the annual goal would receive
the annual stipend minus the one of more quarters that they failed to meet the bench marks. For example an
employee who meets the annual goal and meets three of the four quarters would receive 75% of the annual stipend.
One of the main benefits of this idea is to provide a means to encourage the sustainment of a healthy lifestyle. The
program that we did last winter, the city's greatest loser program, had lots of participants and a lot of employees lost
a lot of weight. However, if we went back now and evaluated the same employees I suspect that most have put the
weight back on - it was a great idea, but wasn't sustainable. This idea creates a means of continuously encouraging
an employee to stay healthy, which ultimately will result in some life style changes. I also believe that our health
fund will reap benefits from this program. We looked and we haven't found any other cities doing this, so it is a
very novel approach, but I think one that is well worth considering. [look forward to visiting with you about this
idea on Monday.
