BASIC SERVICES - PART II
Detailed Scope of Basic Services - Part II
Basic Services - Part II will consist of six phases as follows:
. Right-of-Way & Topographic Surveying
. Hydrologic & Hydraulic Analysis / FEMA Map Revision
. Storm Water Pollution Prevention Plan
. Section 404 Permitting
. Geotechnical Investigation
. Reimbursable Expenses
A. Right-of-Way & Topographic Surveying
1. Horizontal and vertical control will be established and tied to available City control. Three
permanent horizontal/vertical control points will be set outside the limits of construction along
Coppell Road for use by the Contractor during construction.
2. Records research at the County to determine ownership and existence of easements and right-
of-way on the properties affected by the proposed roadway.
3. Perform field surveys to locate existing rights-of-way, property lines, boundary comers and
easements for all parcels affected by the proposed roadways. Review of County information and
field data to establish the existing right-of-way for the roadway. A Registered Professional Land
Surveyor will prepare a Right-of-Way Strip Map and a Horizontal & Vertical Control Map to be
included in the final construction plans.
4. A Registered Professional Land Surveyor will prepare individual parcel exhibits and legal
descriptions to delineate the areas proposed for right-of-way dedications and easements. The parcel
exhibits and legal descriptions will be suitable for inclusion in right-of-way and/or easement deeds
to be prepared by the City. This task allows for the preparation of 4 land descriptions and exhibit
maps.
5. Set property comers on all new right-of-way and/or easement parcels that will be acquired by
the City.
6. Perform field topographic surveys to compile sufficient data for design. Cross-sections will be
5
Attachment 'A'
taken at 50 ft. intervals, 150 ft. wide maximum width and include all driveways, lead sidewalks and
cross streets. Produce a topographic map with a one-foot contour interval suitable for civil design.
7. Obtain up to six creek cross-sections to be used in the HEC-2 models of Grapevine Creek.
8. Obtain field data on existing franchised utilities above ground and as located and uncovered by
the owners ofthe utilities.
9. Obtain field data on existing City water mains, wastewater lines, storm sewer mains, and
streetlights.
10. Tie-in and identify all trees, shrubs, landscaped areas, sprinkler heads, irrigation controls and
valves, mailboxes, walls, signs and other features that are within the area to be surveyed.
11. Set horizontal and vertical control and stake the centerline of the roadway every 500 feet
including P.C.'s and P.T.'s of curves.
12. Re-stake property and easement comers at the conclusion of construction.
B. Hydrologic & Hydraulic Analysis and FEMA Map Revisions
1. Data Collection
Obtain the existing HEC-l models for Grapevine Creek from the City and FEMA. Obtain the
regulatory FEMA hydraulic models and the most recently adopted City models for Grapevine
Creek.
2. Hydrologic Analysis
Develop a fully developed conditions hydrologic model for the Grapevine Creek basin.
3. Hydraulic Modeling
Grapevine Creek - Import Grapevine Creek into HEC-RAS for that portion of the Creek needed
to model the proposed roadway and its potential upstream impacts. This run will be the
Duplicate Effective model. The imported model is not expected to extend upstream far enough
to require that any other bridges be imported into the model.
A Corrected Effective model will be developed by supplementing the Duplicate Effective model
with the topographic data being used for this design project. The model may be extended
downstream of its current point of beginning in order to be able to add the proposed bridge and
embankment to the Grapevine Creek model. Extending the model will be needed in order to
adequately assess bridge scour potential for the proposed bridge. The Corrected Effective model
will be analyzed for FEMA regulatory discharges as well as the fully developed discharges obtained
from the hydrologic study.
Pre-Project and Post-Project models will then be developed that incorporates the proposed roadway
and bridge. The proposed bridge will be designed in accordance with City guidelines to prevent
adverse impacts resulting from fully developed basin discharges as determined in the hydrologic
6
Attachment 'A'
study. The bridge will also be designed to be in compliance with FEMA guidelines for the FEMA
regulatory discharges.
4. Scour Analysis
A scour analysis will be prepared in accordance with HEC-18 and HEC-20 guidelines. Abutment
scour will not be computed. Rather, riprap needed to protect against abutment scour will be
designed.
5. Hydraulic Analysis Report
Develop a preliminary Hydraulic Analysis report documenting the floodplain analysis process,
results, and conclusions. The preliminary report will be submitted for City review with the
preliminary design submittal. A Final Hydraulic Report will be prepared that incorporates City
review comments and final design elements and will be submitted with the final design
submittal.
6. Letter of Map Revision
A FEMA Letter of Map Revision (LOMR) will be prepared and submitted to the City for review
after the completion of construction and preparation of Record Drawings. City review comments
will be incorporated into the submittal and the LOMR package will be prepared for the City to
submit to FEMA.
7. Assumptions:
A Conditional Letter of Map Revision (CLOMR) will not be required. HZI will not be
responsible for payment of any FEMA review fees. The LOMR submittal will be limited to
hydraulic changes resulting from this project and will not include updating information for
previous projects or for revised hydrologic discharges.
C. Phase 1 Environmental Site Assessment
The purpose of an Environmental Site Assessment Phase I is to identify any recognized
environmental conditions with the subject property. Recognized environmental conditions
includes the likely presence of any hazardous substances or petroleum products on a property
under conditions that indicate an existing release, a past release, or a threat of a release of
substances or products on the property, on the ground, ground water or surface water of the
property. The identification of recognized environmental conditions in connection with the
subject property may impose an environmental liability on the owners or operators of the subject
property and thus reduce the value of the site, or restrict the use of the site or marketability of the
site. This task includes the collection of data, research, and preparation of the Phase 1 Report.
D. Archeological Investigation
An archaeological and or cultural resources investigation tries to identify if any structures, sites,
campgrounds, or burial sites, both current and pre-historic, exist on or near the subject property.
The Texas Historic Commission (THC) requires such a clearance before construction and an
Antiquities Permit is required for such investigations. This task includes investigation in the
field, permitting and the preparation of a report.
7
Attachment 'A'
E. Storm Water Pollution Prevention Plan
Storm Water Pollution Prevention Plan and Notice of Intent (NOI) - Engineer will prepare a
comprehensive Storm Water Pollution Prevention Plan (SW3P) along with the required Notice of
Intent (NOI) for the construction portion of the project.
F. USACOE Nationwide Permit
Engineer will conduct an investigation to determine the location and extent of areas that have a
high potential of being jurisdictional waters of the United States, including wetlands, within the
project impact boundaries. Initial efforts will involve analysis of National Wetland Inventory
Maps, the Dallas County, Texas Soil Survey, and the most recent aerial imagery to locate areas of
highest probability. This will be followed by a field reconnaissance to investigate all suspect
areas on the ground to determine the presence of wetlands or jurisdictional waters of the U.S. as
recognized by the U.S. Army Corps of Engineers. Observations will be made regarding
predominant vegetation, soil characteristics, and hydrology indicators to ascertain if specific
areas meet the requisite criteria for jurisdictional waters. If it is determined that jurisdictional
waters / wetlands exist in the project impact area, a detailed delineation and survey will be
performed.
Regulations will require that the owner exercise avoidance and minimization of impacts to
jurisdictional waters and wetland areas. If impacts are unavoidable, a determination will be
made as to the overall affected area and a permitting strategy developed. Generally, if impacts
are less than 1110 acre, a Nationwide Permit can be used. If impacts are greater than Y2 acre, an
Individual Permit is required. In either case, compensatory mitigation will be required based on
overall amount impacted, type and quality of the resource lost, and other factors.
Engineer will prepare and submit an application for a U.S. Army Corps of Engineers
(USACOE) Nationwide Permit for the project based on the applicable plan current at that time.
The application will describe the proposed actions, the purpose of the actions, and any methods
of mitigating the proposed losses of waters / wetlands. This task will also include coordination
with the USACOE and TCEQ, U.S. Fish and Wildlife, State Historical Preservation Officer,
responding to other government agency and public comments as required, and finalization of the
permit documents.
G. Geotechnical Investigation
Engineer will contract with a geotechnical-consulting firm to conduct a geotechnical investigation
of the project area. The investigation will provide roadway and bridge borings to sample and
evaluate subsurface conditions along the proposed project alignment. From this data, the
geotechnical consultant will develop engineering design parameters for design and construction of
the proposed improvements and will provide recommendations regarding these improvements in
the form of a written report.
8
Attachment 'A'
H. Reimbursable Expenses
Reimbursable expenses accrued through printing as described in the Basic Services, newspaper and
print adds, TDLR fees, FEMA fees, printing fees at the County, filing fees, review and processing
fees, mileage, delivery fees, and other out-of-pocket expenses shall be reimbursed at cost upon
receipt of an invoice from Engineer.
