Wrightwood Forest Health Project, Wrightwood, CA - US Forest Service As part of the overall Forest Health Project, this project involved retracing and remarking the Forest Boundary lines surrounding the community of Wrightwood. In all, it required the retracing and maintaining of 5 miles of previously posted line, along with locating, monumenting, flagging and posting to Forest Standards of 10 miles of previously unsurveyed and unposted forest boundary line which followed se...ctional breakdown lines. Locating the previously unsurveyed lines required location and/or retracing the sectional controlling corners for eight complete sections and portions of several others, all in very steep and rugged mountainous terrain with 3000’ of elevation difference. In addition to existing monumentation found, positioned and used for the forest corners, 15 new USFS standard post monuments were set to define previously unmonumented corners. Records of Survey of twelve sheets each, were filed in both Los Angeles and San Bernardino Counties, addressing the idiosyncrasies of both counties not a small task on it’s own. The project was performed efficiently by first computing state plane coordinate search locations for all record monumentation using Star*Net Least Squares and all existing records weighted appropriately for the period in which the boundary control monuments were set. Then, using the best combination of Static GPS, RTK GPS, Total Stations, compass, chain, and will power, we physically located all necessary boundary control. Once found, and generally at the same visit, the existing monumentation was tied to control using Static GPS with Total Station offsets for those locations where GPS would not function. All final monuments were set by total station kick-overs from close Static GPS points positioned in the search phase of the project. All found and set corners were rigidly tied to the National Spatial Reference System through GPS static connections to two bracketing Continuous Operating Reference Stations (CORS), and those resulting positions recorded on the filed Records of Survey to preserve the precise location of all corners and lines.

Lee and Kyle Canyon Boundary Surveys, Mt. Charleston, NV - US Forest Service This project involved retracing and remarking the Forest Boundary lines surrounding private in-holdings in Lee and Kyle Canyons. The project required the retracing and posting of 4 miles of Federal / Private Boundary lines. The survey required location and/or retracing the sectional controlling corners for three sections, as well as Tracts within the independent resurvey of T19S, R56E, MDM. Elevat...ions throughout the project area ranged 7,500 to 8,500 feet. A total of approximately 7,500 total station, Static, and RTK observations comprise the final least squares network adjustments. Approximately 86 Forest Service dig-in monuments, set in concrete, were set marking the resurveyed boundaries. Three Records of Survey were compiled and filed with the Clark County Recorders Office. The project was performed efficiently by first computing state plane coordinate search locations for all record monumentation using Star*Net Least Squares and all existing records weighted appropriately for the period in which the boundary control monuments were set. Then, using the best combination of RTK GPS and Total Stations, we physically located all necessary boundary control. Once found, and generally at the same visit, the existing monumentation was tied to control using Static GPS and/or Total Station network traverse. All final monuments were set by total station kick-overs from control established during the search phase of the project. All found and set corners were rigidly tied to the National Spatial Reference System and those resulting positions recorded on the filed Records of Survey to preserve the precise location of all corners and lines.

Boundary and ROW Acquisitions, US / Mexico Border Fence - Los Angeles District, US Army Corps of Engineers This project consisted of boundary and cadastral surveying for right of way acquisitions along the U.S. / Mexico International Border. Specifically, the acquisitions involved existing roads currently being used by Customs and Border Protection (CBP), as well as roads and staging areas that were utilized in the construction of the new border fence. Many of these roads h...ave been utilized by CBP for years, however, no legal right existed to allow such use. As such, numerous properties had to be surveyed, along with said roads and staging areas, in order to compile legal descriptions to facilitate acquisitions and/or condemnations. To date, this project has involved 4 separate task orders and three modifications to the fourth task order, a total of 29 separate owners and 31 individual parcels from west of Tecate in San Diego County to west of Calexico in Imperial County. The projects cover approximately 13 fractional townships along the border, requiring extensive cadastral retracement throughout the area.

Aerial Mapping of 10 Cities within the Navajo Nation - Los Angeles District, US Army Corps of Engineers This project consisted of surveying and mapping services for flood plane studies throughout the Navajo Nation and focused on 10 of the largest population centers within the Nation. These sites were spread out across a vast area covering Arizona and New Mexico, and crossing three separate State Plane Zones. The sites included Ft. Defiance, Kayenta, Tuba City, Chinle, Leupp..., Many Farms, and Ganado in Arizona, as well as Tohatchi, Shiprock, and Crownpoint in New Mexico. This project was Task 24 under contract W912PL-06-D-0013 and totaled $497,792 in professional services. The 10 project areas covered 117 square miles, nearly 75,000 acres, required 86 individual permanent control aerial targets, and was flown at a photo scale of 1=1200’ with Airborne GPS control. The resulting products were produced at a scale of 1=160’ with a 4 foot contour interval. For each site, the established permanent survey control was compiled into a control map together with DA1959 data sheets for each station. Each site was delivered in Microstation together with an InRoads surface, ESRI Geodatabases, digital orthophotography, and photo indexes. All of the data was submitted to the Corps and in turn forwarded to the Nation for their future use. Most importantly, the project required close cooperation with that Navajo people. Our crews required escorts at all times which required our schedule to be flexible to accommodate theirs. We found the Navajo people, and our escort in particular, to be extremely helpful and friendly. The success of this project hinged on these escorts as many of the people on the Reservation still speak Navajo, do not speak English, and are many times distrustful of outsiders. The project was a high priority task for the Los Angeles District Colonel. It was fast tracked from the beginning. Estimating, negotiating, and contracting were completed within less than a month. The project was begun immediately upon notice to proceed and was completed within the 6 month period of service as requested. Johnson-Frank received an Very Good Performance Rating for this project
