Such major projects usually require either an Environmental Impact Statement (EIS) or Environmental Impact Report (EIR) to satisfy the National Environmental Policy Act. As part of this analysis, the need for a noise barrier is evaluated for each individual highway project. Under the Type I program, if a noise barrier is determined to be reasonable and feasible, it must be constructed as part of the project. What is a Type I project? (1) The construction of a highway on a new location; (2) The physical alteration of an existing highway where there is either:(i) Substantial Horizontal Alteration. A project that halves the distance between the traffic noise source and the closest receptor between the existing condition to the future build condition; (ii) Substantial Vertical Alteration. A project that removes shielding therefore exposing the line-of-sight between the receptor and the traffic noise source. This is done by either altering the vertical alignment of the highway or by altering the topography between the highway traffic noise source and the receptor; or,(3) The addition of a through-traffic lane(s). This includes the addition of a through-traffic lane that functions as a HOV lane, High-Occupancy Toll (HOT) lane, bus lane, or truck climbing lane; (4) The addition of an auxiliary lane, except for when the auxiliary lane is a turn lane; (5) The addition or relocation of interchange lanes or ramps added to a quadrant to complete an existing partial interchange; (6) Restriping existing pavement for the purpose of adding a through-traffic lane or an auxiliary lane; or,(7) The addition of a new or substantial alteration of a weigh station, rest stop, ride-share lot or toll plaza.(8) If a project is determined to be a Type I project under this definition then the entire project area as defined in the environmental document is a Type I. Highway agencies should take a broad approach to defining turn lanes when considering projects with auxiliary lanes. Generally, consideration for auxiliary lanes on local roads should be limited to those that could be used as a through lane rather than lanes used for parking, speed change, turning or storage for turning weaving. For interstates, limit consideration to auxiliary lanes between two closely spaced interchanges to accommodate weaving traffic and auxiliary lanes carried through one or more interchanges. http://www.fhwa.dot.gov/environment/noise/regulations_and_guidance/faq_nois.cfm#note2GeoPlanIIThe Type I program covers noise barrier construction coincidental with construction of major highways on new location, or physical alteration of an existing highway such as substantial realignment or widening to increase the number of through traffic lanes thereby increasing capacity.

Under the Type I program, if a noise barrier is determined to be reasonable and feasible, it must be constructed as part of the project. What is a Type II project? Usually called a retrofit project, a Type II project is a proposed Federal or Federal-aid highway project for noise abatement on an existing highway. Type II projects are not mandatory and are at a State's discretion. Projects of this type are proposed solely at the option of a State DOT, and specific requirements for the project are determined by the individual State DOT. Federal participation in the funding of such projects is limited to those that propose abatement measures along lands that were developed prior to construction of the original highway.

Noise barriers are solid obstructions built between the highway and the homes along a highway. They do not completely block all noise they only reduce overall noise levels. Effective noise barriers typically reduce noise levels by 5 to 10 decibels (dB), cutting the loudness of traffic noise by as much as one half. For example, a barrier which achieves a 10-dB reduction can reduce the sound level of a typical tractor trailer pass-by to that of an automobile. Barriers can be formed from earth mounds or "berms" along the road, from high, vertical walls, or from a combination of earth berms and walls. Earth berms have a very natural appearance and are usually attractive. They also reduce noise by approximately 3 dB more than vertical walls of the same height. However, earth berms can require a lot of land to construct, especially if they are very tall. Walls require less space, but they are usually limited to eight meters (25 feet) in height for structural and aesthetic reasons.

There is no "number standard" which requires the construction of a noise barrier. Federal requirements for noise barriers may be found in Title 23 of the U.S. Code of Federal Regulations, Part 772, "Procedures for Abatement of Highway Traffic Noise and Construction Noise." The Federal Highway Administration noise regulations apply only to projects where a State transportation department has requested Federal funding for participation in the improvements. The State transportation department must determine if there will be traffic noise impacts, when a project is proposed for (1) the construction of a highway on new location or (2) the reconstruction of an existing highway to either significantly change the horizontal or vertical alignment or increase the number of through-traffic lanes. If the State transportation department identifies potential impacts, it must implement abatement measures, possibly including the construction of noise barriers, where reasonable and feasible. Federal law and Federal Highway Administration regulations do not require State transportation departments to build noise barriers along existing highways where no other highway improvements are planned. They may voluntarily do so, but they are solely responsible for making this decision.

GeoPlan relied on the integrity of the original data layer's topologySpatial and Attribute InformationPrimary Data Collection - GPS In late May 2004, the Center for Urban and Environmental Solutions deployed a field team to ground-truth the original 30 noise abatement walls in the June 2000 Report. Utilizing a Trimble GeoXT with GPS correct for real-time post-processing, the field team collected GPS information to verify the location of these barriers. During the GPS field work, three (3) new walls were identified in District 1 along the I-4 Corridor, the GPS information was collected for these walls as well. Once research staff confirmed these were owned by FDOT, they were included into the Statewide Noise Abatement Geodatabase. GPS coordinates were collected by the research field team for 33 noise abatement walls. District 4 and District 6 indicated that they would be initiating their own GPS collection during the summer and fall of 2004. Rather than replicate this effort, CUES coordinated with these two districts to obtain the completed GPS information and import it into the Statewide Geodatabase. However, approximately seven walls were not included in these two Districts inventories. Therefore, CUES field team used GPS to collect wall information mainly for the Sawgrass Expressway and the Florida Turnpike. Overall GPS coordinates were collected for 40 walls by CUES. The internal setting of the GeoXT's GPS were set to ensure the highest possible accuracy. The settings utilized are as follows: PDOP: (Position Dilution of Precision) : 6 or less SNR (Signal To Noise Ratio): 4 Elevation Mask: 15% Number of Satellites: 4 or Higher Differential Correction: WAAS Each noise barrier wall in the region was surveyed to obtain both spatial, attribute and photographic information necessary for the project. Upon arrival to the particular barrier wall, the team would investigate the following conditions before undertaking the survey: · Traffic volume & Safety conditions · Survey Obstacles · GPS Satellite Visibility · GPS Availability Upon arrival to the location, traffic volume was determined by the amount of traffic traveling adjacent to the wall of interest. The estimated volume determined whether it was judged safe for a foot survey or required use of a vehicle. Hard hats and florescent safety vests were worn at all times while conducting the surveys. Numerous barrier walls surveyed had large swaths of vegetation planted next to them. Major types of vegetation included: Sable Palm trees, Sea Grape and various other bushes. These vegetation lines often followed the length of the given wall an ranged on an average from 10-75 feet. Since many of the walls had some type of vegetation, an offset was incorporated into the survey. Generally all surveys were done on an average of 20 feet in front of the wall. Many of the walls not only had a vegetation line in front but also a layer of standing water. This situation occurred in areas where the walls possessed a gully or depression directly in front of the vegetation line. In many situations, the accumulated water actually formed a small linear wetland including typical wetland flora and fauna which included unfortunately high concentrations of biting insects. If these water bodies existed, the offset was increased to account for the additional obstacle so that the survey could continue. Other barriers to the survey included manmade structures such as tollbooths, embankments, bridges and narrow walks. If such obstacles were encountered, the situation was noted in the attribute table and the offset increased as needed. GPS is a line of sight technology which relies on the ground based receiver the ability to have a clear and unobstructed line of sight to the GPS satellites. noise barrier walls provide a unique problem in that they can obstruct half of the sky depending on how close the survey is conducted to them. Due to this fact, an offset was also needed to obtain the best possible satellite lock. GPS uses a measurement called PDOP (Position Dilution of Precision) to indicate accuracy. To ensure high accuracy GPS positioning, it is recommended that the PDOP value be less than 6. During all wall surveys, PDOP was monitored very closely and any measurement greater than 6 was resurveyed. Once the Noise Barrier Wall was cleared to survey, the walking team member would activate the Mobile GIS/GPS unit and begin logging the poly-line feature. At the beginning of the logging, an initial starting coordinate would be relayed to the vehicle team member for input into handwriting log. If a walking Survey was done, the survey team member would walk the length of the wall with the vehicle team member following along to provide a look out for traffic. At the halfway point of the survey, the walking team member would again call out the coordinate of the middle of the wall to the vehicle team member. Once the entire length of the wall had been traversed, the walking team member would stop the logging and fill in the custom input form in the ArcPad software. Digital photos were also taken at each survey location. After each wall was surveyed, the team would back up the data on the GeoXT mobile device and then download the data onto a laptop computer. This procedure was completed at the location incase data was lost and the survey would have to be redone. Once back at the office, all data for that day was downloaded onto the project server to be used by the GIS section. Acquisition from Individual Districts of Walls in GIS format According to interviews conducted during this project among FDOT personnel, at the time of interviews, District offices were not maintaining an inventory of their noise barriers in GIS. However, in the summer and fall of 2004, two District offices used GPS technology to store their noise abatement walls in GIS. District Four utilized GPS to store both the point (begin/end points) and line feature classes representing 95 noise abatement walls. District 4 provided the research team with their personal geodatabase. Next, the point and line feature classes were merged and spatially projected into the Statewide Geodatabase. District 4 also created a hyperlink to the photos collected during their GPS work. This hyperlink is included as part of the Statewide Geodatabase. District Six utilized GPS technology to capture the begin node and end node for each wall. However, no line feature classes were created. Utilizing the GPS begin and end nodes, the research team digitized the line feature class representing the noise barriers for approximately 84 out of 96 total walls in District 6. A Trimble GeoXT was used to collect the points and linear features depicting the remaining 12 barriers. On Screen (Heads-up) Digitizing This spatial data collection technique, based on utilizing high quality, rectified aerial photos and other georeferenced GIS layers, was used to primarily to edit the spatial data collected through GPS for relative positional accuracy purposes. The level of accuracy of the derived dataset is taken from the initial accuracy of the digital image along with georeferenced GIS layers. One of the challenges was to utilize aerial photos in GIS at an acceptable resolution needed to create and edit spatial features for all District offices that have noise abatement walls. The central problem is that most ortho photos in GIS are collected by county governments who collected this raster information at varying scales, different data formats (e.g. MrSID, TIF, JPEG, SDE) and/or captured at different time frames. Based upon these challenges as well as the degree of acquiring these raster features, it was decided to utilize ESRI's ArcWeb Services. One of ArcWeb Services offered is access to GlobeXplorer's 'Citipix/Digital Ortho' which was used to perform the spatial edits required to verify and/or 're-align' the GPS collected data relative to scale of FDOT's GIS base map layers. Citipix is the largest high-resolution aerial imagery dataset available online through ArcWeb Services. Captured at six-inch resolution and in 24-bit color, Citipix is precision geo-referenced and ortho-rectified. It covers over 7,000 cities and towns in over 73 metropolitan areas in the United States, with a total area of over 90,000 square miles. Because of Citipix high resolution, it provided the optimal back ground layer to digitize, edit, and verify the linear features representing the walls. Using GPS points collected by District 6 which represent the begin and end nodes for each wall along with GlobeXplorer's digital orthophotography, the line feature classes for these walls were digitized. 96 out of the 217 walls within the Statewide Geodatabase were digitized. District 6 accounts for approximately 44% of all noise barriers in the Statewide Geodatabase.2004-01-01T00:00:00CUESGeoPlan took the data from the Statewide Noise Barrier GeoDatabase two disk set in May 2005. The layer was called NBGD_ALL and located in the Feature Dataset NBGD of the FDOT_NAB_GDB.mdb (on disk 1). This feature class was in Albers HPGN. A DESCRIPT field was added and based on the field ROAD_DESCR.2005-05-01T00:00:00GeoPlanNoise barrier locations were received from the Florida Department of Transportation via email as a spreadsheet in excel format in November of 2009. These noise barriers have been built since the initial CUES data was created or are planned to be built in the future. Noise barrier records containing TO and FROM, Latitude and Longitude information were formatted to Decimal Degrees. Once in Decimal Degrees the records were brought into ArcMap. Using the XY Tool in ArcMap the records were then converted to point features. These point features were then used as a guide along with Google Maps Street View to properly locate these noise barrier line features. Noise barriers without to and from latitude and longitude information were created using the RCI road id associated with the barrier and the beginning and ending mile post. Line route events were created using the basemap.route.road RCI basemap coverage and a table provided by FDOT that contained noise barrier locations. The route events were created in ArcMap 9.3.1 using the Add Route Events tool. Barriers that have already been constructed were verified when possible using Google maps street view or aerial imagery. Planned barriers rely on the accuracy of the RCI Road ID, Beginning Mile Post, and End Mile Post data provided by FDOT. Noise barrier records with no TO and FROM latitude and longitude or RCI Road ID and Beginning and Ending Mile Post information have been placed when possible based on the approximate location, group, and Highway / Route Number fields. In some instances not enough information is available to confidently locate these barriers. At this time these records have been omitted until further information on their location can be obtained. There are currently 45 noise barrier locations that have been omitted.2010-04-10T00:00:00GeoPlanGeoPlan reviewed the original table of unlocated constructed sound barriers. During this process 5 of the 8 existing missing sound barriers were located. There are currently 40 noise barrier locations that have been omitted. It was noted that a few roadways maybe creating new sound barriers in the future.
