SUMMARY & RECOMMENDATION
The City has been working to improve and refine the City of La Porte's road design criteria. Standardization of
design criteria of public roads simplify and insure quality roads that are constructed to last and be in general
agreement with roads built for Harris County and the Texas Department of Transportation. As part of the ongoing
outreach efforts to involve the citizens in their local government, a voluntary public hearing on the road design
criteria is sought to receive public input Another part of this outreach program entailed the distribution of the
proposed criteria to various engineering consultants including Lockwood, Andrews & Newnam, Inc., Manning
Engineering, ESOR Engineering, Windrose Services, Klotz & Associates, Inc., Brown & Gay, Inc., local developer
Eddie Gray, H. Carlos Smith, LJA Engineering, and Claunch & Miller. Conunents were received from Claunch &
Miller, Windrose Services, and Klotz & Associates. Intemally, the proposed design criteria were reviewed by
Public Works whose conunents were sought. The proposed road design criteria will become Chapter 6 of the Public
Improvements Criteria Manual (pICM). Currently there is only one chapter ofPICM - Chapter 5 which deals with
the design of storm sewer drainage systems. The need for a full and complete PICM stems from the Development
Ordinance which refers to PICM as being the location for applicable design criteria for use in the design of public
~~ms. .
At its October 16,2003 meeting the La Porte Planning & Zoning Commission voted to reconunend approval of the
proposed Chapter 6 to the City Council.
Action ReQuired bv Council:
Consider holding a public hearing to receive any citizen input on the proposed Paving Design Criteria and consider
approving a resolution adopting the Paving Design Criteria Chapter of the Public Improvements Criteria Manual.

streets in conunercial and industrial areas, grades should be less than 5% and flatter grades are encouraged.
D. Vertical curves shall be designed when algebraic difference in grade exceeds 1%.
Elevations shall be shown on the construction plans at a minimum of 10 foot horizontal
intervals through vertical curves. The gradient for tangents to vertical curves at railroad
crossings shall be a maximum of 3.5%. All crest vertical curves shall be determined by
sight distance requirements for the design speed. The minimum design speed on any
vertical curve shall be based on street classification.

and may not be located on private property.
3. Major thoroughfares with a centerline radius of the right-of-way less than 2000
feet shall be designed in accordance with the guidelines for superelevation as
specified in the American Association of State Highway Transportation
Officials (AASHTO), A Policy on Geometric Design of Highways and Streets.

G. For the purposes of these design standards, tangent length is defined as the distance
between the point of tangency and the point of curvature of two adjacent curves along the
centerline of the street right-of-way.
Paving Design Criteria Page 4 of9
.
.
I. The minimum tangent length between reverse curves shall be 100 feet on principal

right-of-way line shall be as follows:
a. Streets intersecting major arterials: 200 feet.
b. Streets intersecting minor arterials: 150 feet.
c. Streets intersecting collector and local streets: 125 feet
5. Proposed streets shall be aligned with existing streets where possible. Offset
intersections shall be avoided at all costs and shall not be pennitted if the offset
distance is less than 125 feet.
6. Lane drop tapers shall extend a minimum of 50 feet beyond the intersection.
I. Minimum lane transition lengths shall meet or exceed requirements of the Texas Manual
of Uniform Traffic Control Devices (I'MUTCD). Pavement width transitions shall

40, 45, 50, 55 mph are 230, 330, 430, 550 and 680 feet respectively. These
lengths exclude the taper lengths.
2. Taper lengths should be calculated for roads with design speeds greater than or
equal to 45 mph by using taper lengths (L) equal to 0.6 times the design speed
(S) multiplied by the offset (W), L=0.6SW. For design speeds less than 45 mph,
the taper length (L) equals the offset multiplied by the design speed (s) squared,
then divided by 155, L=WS2/155. The distance for tapers should be lengthened
if the road is curved based on recommendations from the Professional Engineer
of Record.
J. Left Turn Lanes
I. Minimum storage bay lengths need to be supplied for at least 2 passenger
vehicles; or for the number of left turning vehicles likely to arrive at the
intersection in an average 2 minute span in the peak hour of traffic. If there is a

standards:
1. For median openings including left turn lanes, the storage and taper lengths
mentioned in these design criteria shall apply.
2. The median opening at the intersection of two streets shall be the width of the
minor right-of-way plus 10 feet.
3. No median openings will be allowed for private drives, private streets or
commercial shopping center entrances.

SUMMARY & RECOMMENDATION
The City has been working to improve and refine the City of La Porte's road design criteria. Standardization of
design criteria of public roads simplify and insure quality roads that are constructed to last and be in general
agreement with roads built for Harris County and the Texas Department of Transportation. As part of the ongoing
outreach efforts to involve the citizens in their local government, a voluntary public hearing on the road design
criteria is sought to receive public input. Another part of this outreach program entailed the distribution of the
proposed criteria to various engineering consultants including Lockwood, Andrews & Newnam, Inc., Manning
Engineering, ESOR Engineering, Windrose Services, Klotz & Associates, Inc., Brown & Gay, [nc., local developer
Eddie Gray, H. Carlos Smith, UA Engineering, and Claunch & Miller. Comments'were received from Claunch &
Miller and Klotz & Associates. Internally, the proposed design criteria were reviewed by Public Works whose
comments were sought. The proposed road design criteria will become Chapter 6 of the Public Improvements
Criteria Manual (pICM). Currently there is only one chapter of PICM - Chapter 5 which deals with the design of
storm sewer drainage systems. The need for a full and complete PICM stems from the Development Ordinance
which refers to PICM as being the location for applicable design criteria for use in the design of public systems.
At its October 16,2003 meeting the La Porte Planning & Zoning Commission voted to recommend approval of the
proposed Chapter 6 to the City Council.
Action ReQuired bv Council:
Consider holding a public hearing to receive any citizen input on the proposed Paving Design Criteria and consider
approving a resolution adopting the Paving Design Criteria Chapter of the Public Improvements Criteria Manual.
