Eagle
Landing, Sections One, Two and Three (Harris County
MUD No. 399) Harris County, Texas
Project consists of general planning, platting,
surveying, preliminary and final engineering and
construction management for the development of
238.5 acres located in Harris County at the north
corner of Ella Boulevard and Kuykendahl Road in
Harris County MUD No. 399. Current development
consists of three completed sections, totaling
378 lots on 90 acres of property. EHRA completed
preliminary and final plats for the three sections,
received approval on construction plans for the
water, sanitary sewer, storm sewer, water quality
and pavement facilities to serve the three sections
and perform construction inspection and general
management of the project to ensure that it was
built according to designs and specifications.
Project also has several regional facilities required
for the development of the property, which included
drainage study of the region, channel improvements,
excavation of a regional detention basin and construction
of off-site waterlines to serve the development.
The drainage study for the development consisted
of an analyses of the North Fork of Greens Bayou
(HCFCD Unit No. P145-03-00) and the effects of
a proposed development located in the drainage
area for the North Fork Greens Bayou Regional
Detention Pond (HCFCD Unit No. P525-01-00). The
goal of the drainage analysis was to prove that
P145-03-00 (“the channel”), after
improvements, had the ability to carry the 100-year
storm runoff from the P145-03-00 watershed (including
the proposed development runoff) from discharge
point to the regional detention pond site without
creating any adverse effects to the water surface
elevation in the channel. The existing condition
of the channel and its drainage area were analyzed
and the channel improvements designed to increase
capacity to transport the flows to the regional
detention basin without adversely affecting adjacent
properties. The basin’s operation was improved
based upon the recommendations presented in the
study and implemented during construction of a
side weir structure that allowed for improved
flow between the channel and the basin. EHRA prepared
construction plans and specifications, bid documents
and performed bidding cycle, construction management
and inspection services in addition to coordinating
acceptance of project improvements by TCEQ, HCPID
and HCFCD. The off-site waterline consisted of
design and construction management for a 16-inch
trunk water line for approximately one mile of
16-inch trunk water line to serve Harris County
MUD No. 399 along Kuykendahl Road from Ella Boulevard
to near Richey Road including road and channel
crossings. EHRA prepared construction plans and
specifications, bid documents and performed bidding
cycle, construction management and inspection
services in addition to coordinating acceptance
of project improvements by TCEQ, HCPID and HCFCD. |

Cherie
Cove, Phase One and Phase Two
Houston, Texas
The Cherie Cove project consisted of engineering
design, preparation of construction plans and
specifications, bidding cycle services and construction
management services which include inspection and
processing of pay estimates for a residential
subdivision to serve Habitat for Humanity. The
design consisted of water distribution, sanitary
sewer collection, storm sewer collection and water
quality facilities along with paving design. |

Rivers
Run at the Brazos, Section One
Fort Bend County, Texas
Water, sewer, drainage and paving for 177 single-family
residential lots at the southwest corner of Reading
Road and Benton Road. Development includes the
construction of a large detention / amenity basin,
including an engineered clay liner to maintain
a permanent water surface elevation on the amenity
basin from leaking water. Additionally, a portion
of Gapps Slough was relocated through this development
to accommodate development in this region. |

Towne
Lake, Sections One and Two
Harris County, Texas
EHRA has commenced engineering and development
of a 2,400 acre single-family residential lake
community that will include a 325 acre lake /
detention pond system. EHRA has excavated ½
million yards of dirt, cleared 150 acres of land
and completed two sections (approximately 100
acres). Improved / reconstructed an existing Harris
County Flood Control ditch to be used as a primary
storm sewer outfall and constructed one mile of
sanitary force main and lift station along the
existing West Road to serve the development. |

Rodeo
Palms, Subdivision Improvements
City
of Manvel, Texas
Rodeo
Palms is a 585 acre mixed use development located
in Manvel, Texas. This was the first master planned
community within the City of Manvel which involved
the creation of Brazoria County Municipal Utility
District No. 29 and City of Manvel TIRZ No. 1.
Unique aspects of this project include the detention
system and amenity lakes; constraints on the shallow
drainage outfall depth and discharge rate which
were a challenge for the project drainage. This
project contains two lift stations, eight lakes,
a water plant and wastewater treatment plant.
The project included a roadway crossing the Gulf
Coast Water Authority irrigation canal. To enhance
access to the project, we designed and constructed
acceleration and deceleration lanes on SH 288. |

Rough
Hollow – Subdivision Improvements
Lakeway,
Texas
Professional
services for platting, design plans and construction
administration for 15-acre Yacht Club and 20-acre
Villas condos of a nine phase project on Rough
Hollow Drive and fronting Rough Hollow on Lake
Travis. Project included layout and design of
roadways, storm sewers, water, wastewater and
wastewater pump station over difficult terrain
including a bridge spanning a deep channel. EHRA
coordinated consultants performing other engineering
services for the project (surveying and geotechnical). |

Crossing
at Onion Creek – Subdivision Improvements
Austin,
Texas
Professional
services for platting, design plans and construction
administration for 92-acre development on E. Slaughter
Lane at Brandt Road. Project consists of five
phases and 464 lots, including three separate
water quality treatment facilities. First three
phases and off-site waterline improvements were
designed concurrently. FHA lot grading was provided
for all residential lots in the development along
with grading of remaining commercial tracts. EHRA
coordinated consultants performing other engineering
services for project (surveying, transportation,
geotechnical and structural). Travis County permitting
was also key. Worked with developer on layout
of lots and FHA lot grading to allow many prime
trees to remain upon completion of construction.
This included design of water quality and detention
pond preserving a 72-inch diameter oak tree along
Brandt Road. |

Rivers
Mist
Fort
Bend County, Texas
Project
consists of general planning, platting, surveying,
engineering design and construction management
services for the development of a 175 single-family
residential lot development located within the
City of Rosenberg ETJ. This project included the
design of a detention/amenity basin which serve
the Rivers Mist development located within two
drainage watersheds. A complete Watershed Analysis
of Gapps Slough was required by Fort Bend County
Drainage District to prove that the proposed development,
upon ultimate build out, would not impact the
existing channel or surrounding properties. The
development also included modifications of the
existing Reading Road, including the construction
of a left turn lane and closure of existing median
break. This project will be completed in three
sections. Section One, consisting of 52 single-family
lots, is complete.
