EXPERIENCE

PARKS/GREENBELTS/PRESERVATION AREAS

Pease Park is an urban park paralleling Shoal Creek and is steeped in Texas History. Originally a native American site, it was also a campsite for General Custer’s troops (many of whom died at the site due to Cholera) and was the site of a gold rush. Purchased by Governor E.M. Pease and his wife as part of his larger estate, they later donated it to the City of Austin as parkland. It was left unimproved for fifty years, but local groups raised money and built benches, restrooms, and a wading pool, thereby creating a used and well-loved community space. It is considered Austin’s oldest park, not including the four original squares created in the original map of Austin. Landmark Surveying, LP was chosen to provide the field work for a partial boundary, topo and tree survey, establishing a network using existing City of Austin control. Approximately 500 trees three inches and wider in diameter were measured, plotted, and identified. Over the course of the last twenty-five years, Landmark had worked along many stretches of Shoal Creek for erosion control and hike and bike trail improvement projects.

This design survey was for ADA improvements including a walking path and other amenities. The approximate 7-acre area was largely in a flash flood zone and a safety protocol was developed to deal with this and other safety issues specific to this park. Landmark collected topographic data and located, tagged, measured and identified all 3” diameter trees and wider. All visible evidence of improvements and utilities were located, and manholes were opened so that flow line data could be obtained. Terrain was unique and included dramatic limestone outcrops, cliffs, and stagecoach tracks. A large creek meandered through the survey. The data was mapped and delivered in AutoCAD format, and topography (1-foot contour interval), with approximately six hundred trees (including canopies), improvements and utilities shown in required layers.

This design and easement survey was for hike and bike trail improvements and included boundary location as needed for preparation of metes and bounds descriptions with accompanying sketches, review of encumbrances listed in title commitments and preparation of title commitment letters. Easements were for public access, drainage, and temporary construction. The survey traversed Boggy Creek for approximately 2,000 linear feet, extending along asymmetrical boundaries, between East 12th Street and the Capital Metro railroad station at Martin Luther King Jr. Blvd. Landmark collected topographic data and located, tagged, measured and identified approximately two hundred 3” diameter trees and wider. All visible evidence of improvements and utilities were located, and manholes were opened so that flow line data could be obtained. Survey included a children’s learning area and apiary teaching structure. The data was mapped and delivered in AutoCAD and PDF format, and topography (1-foot contour interval), with trees (including canopies), improvements and utilities shown in required layers.

Infrastructure

Population growth and density have created a need to upgrade multiple existing electric transmission mains throughout Austin. Landmark has worked on several of these transmission line as-built surveys. CKT 972 is one such example. The survey extended over two miles in length, from McNeil Electric Substation to Howard Lane Electric Substation, being the width of the transmission corridor (100 feet typically) plus an additional twenty-foot wide swath adjoining the existing easement. Visible evidence of utilities and improvements were located. In addition, trees were measured, identified, and tagged. The data was mapped and delivered in AutoCAD and PDF format.

The City of Austin has been subject, over the years, to fast growth compounded by aging water and wastewater lines. In response to this problem, the City formed several rotation lists; each rotation list included a pool of several highly qualified teams that could then be selected for specific projects. As a subconsultant on many of these teams throughout the years, Landmark has a very strong history in design surveying for water and wastewater pipeline projects, both large and small diameter. Landmark was heavily involved in a particularly aggressive program, the Austin Clean Water Program (ACWP), which was developed after the City was issued an administrative order by the Environmental Protection Agency to fix numerous questionable wastewater lines and manholes by June of 2009 or risk paying massive debt. The highly successful program included the standardization of surveying and mapping standards which were used by all who participated in the program. Landmark, working simultaneously with many different civil engineering firms on various projects throughout the City, completed approximately fifteen of these design surveys which included boundary, location of easements and building lines, ownership information, topography, tree surveys, utility location, manhole details and, preparation of new wastewater easements on time, within budget.

Austin’s unique geography makes it highly susceptible to flash flooding and drainage issues. Throughout the years, as density has continued to increase, the importance of developing drainage and flooding solutions has become paramount. Large portions of neighborhoods have had to be purchased by the City in efforts to eliminate escalating costs. Crystal Brook Neighborhood and Creek Bend Neighborhood were two examples of large-scale drainage and flood study areas surveyed by Landmark for the purpose of providing engineers information for building drainage and flood structures. Crystal Brook involved establishing aerial control panel points so that a large aerial map could be developed. In addition to the map control, engineers engaged Landmark to do topographic and tree surveys across approximately 52 acres of heavily wooded land, obtain cross-sections for flood studies, locate utilities and boreholes, and prepare approximately 25 metes and bounds descriptions with accompanying sketches for permanent and temporary easements. The deliverables included AutoCAD and PDF electronic documents.

Building Projects

As a Survey Contractor to Capitol Metropolitan Transportation Authority, Landmark had the opportunity to work on a multitude of mass transit projects, the most significant one being the downtown multi-modal facility in Austin, Texas. The central hub of Project Connect, the facility is an interconnection of light rail lines with bicycle, pedestrian, and bus transport. Landmark’s design survey extended four blocks along 4th Street, from I.H.35 to Trinity, extending across the full length of right-of-way and including outlines and window placements of the existing structures. It also included a detailed survey of the aging Waller Creek Bridge, its structural integrity having been damaged due to erosion from flash flood events. Landmark provided a MicroStation design file of the project.

Plaza Saltillo is a multi-use revitalization development constructed by Rogers O’Brien Construction Company across five urban blocks bordering Interstate Highway 35 on the west and Navasota on the east, and extending south from Fifth Street to the Cap Metro Rail Red Line, in Austin, Texas. Landmark Surveying, LP was chosen to establish base line control and stake gridlines, provide weekly monitoring and slab verification surveys, and prepare letters for Certificate of Occupancy.

In 2007, Landmark performed a GPS control, boundary, and design survey along Carson Creek and at Hoeke Lane for drainage, roadway, and bridge improvements. In 2012 Landmark Surveying, LP returned to the site to do an as-built survey on the new roadway and bridge to enable engineers to confirm construction was built per plans. The survey included re-establishing the horizontal and vertical control network from 2007; Landmark Surveying, LP provided the location and elevations of newly constructed visible surface improvements such as roadways and driveways. Cross-sections along roads were obtained, as well as elevations and extents of the Posten Lane low water crossing and intersecting street returns and driveways. Landmark located and obtained elevations of sidewalks, retaining walls, storm sewer inlets, outfalls, culverts, box culverts, and headwalls, fire hydrants, water valves, vaults, and meters. Flow lines at manholes and inlets, where visible and accessible were collected along with pipe sizes and materials for all storm sewer and wastewater systems. In addition, new cross-sections were surveyed to match the engineering plans to ensure the analysis between proposed and existing information could be made. The engineering construction plans and new Landmark Surveying data was then merged so that items not built according to plan could be identified. An AutoCAD Civil 3D drawing file was provided.

Quality Control and Construction Services

The Program was established to meet planned and future development along the South IH 35 corridor. It identified 24 capital improvements projects (CIP) required to construct 23 water main segments, five wastewater reaches, and one pump station. As a team member, Landmark provided design topographic and tree surveys, improvement surveys, utility staking, several CAD base maps, creek cross-sections, shaft site locations and borehole locations. As well, Landmark established I.H. 35 and City of Austin road rights-of-way, property line locations, staked proposed easements and prepared approximately one hundred certified metes and bounds descriptions with accompanying sketches for proposed easements. In addition to these tasks, Landmark provided third party quality control for other surveyors also involved in the easement process. As part of the Quality Assurance and Quality Control (QAQC), Landmark reviewed approximately 100 easements prepared by others.

Fifth and West is a 2018 addition to the Austin skyline. It stands at 39 stories and is one of the tallest residential towers in Austin. Landmark provided monitoring and elevations of right-of-way features, boundary verification, and metes and bounds descriptions for the tie-back systems. An AutoCAD map showing the Capital View Center Corridor was developed, and as-builts were obtained as each level was built, showing the layout, confirming slab elevations and their relationship to the Capital View Center Corridor.

Located at 2111 Rio Grande Street in the heart of west campus, this 19-story student housing project being built by Rogers O’Brien Construction Company will provide 284 housing units for students. Landmark was asked to provide boundary verification, establish vertical control, control grid lines and building corners with offsets. In addition, Landmark provided a vertical monitoring report and as-built Survey.

Survey Support

Landmark frequently works with world class engineering firms to provide SUE Survey (Level A, B, C and D) support throughout the state. Landmark provides SUE survey support for large roadway projects such as the expansion of I.H. 35 near San Antonio (approximately 23 miles), and Grand Avenue AKA State Highway 99 (approximately 13 miles) in Houston, as well as smaller projects for local firms, C.I.P. and County improvements. Project Deliverables are typically MicroStation or AutoCAD Civil 3 D electronic files.

Landmark works with Geoscientists to locate borings where soil samples have been taken and obtain horizontal and vertical location of monitoring wells. The location of the new Austin Central Library was part of the Seaholm Substation site, which was part of a larger electrical generation and distribution system dating back over a century. The project required Groundwater samplings and soil samplings to check for groundwater and soil contamination, and remove contaminated soil; over the course of many months, Landmark provided survey support including the location of horizontal and vertical control, placement of a grid which was required to be relocated as the site continued to be deeply excavated due to the significant contamination in the soil, and horizontal and vertical location of the borings.

Landmark works with Geotechnical engineers on virtually all public/private infrastructure and building projects, to locate borings horizontally and vertically as part of the soil evaluation process to determine suitability for foundations. Typically, when developing proposals for public/private infrastructure and building projects, a fee is included for this survey task.
