Do you intend to build on property you currently own? If the answer to any of the above questions is "yes", this property may be affected by one or more constraints that you should be aware of before developing or purchasing the property. Most land on Guam is affected in one way or another by flooding, earthquakes, airplane noise and other natural and man-made constraints. These constraints do not necessarily stop you from developing your land but you should be informed of them so as to prevent loss of life, property and reduce inconvenience. This document will help you in identifying natural and man-made constraints that affect your property. It provides a series of maps by village showing the constraints and generally defining them. In addition, this document identifies the government agency to be contacted for more information. You only have to know the general location of your property to use this document. Since certain areas are affected by more than one constraint, you should look at all the maps within your village.

NOISE ZONES Noise Zones are land areas that are affected by aircraft operations. These zones exist primarily in the vicinity of the Guam International Air Terminal, Naval Air Station and Andersen Air Force Base. Aircraft landing and take off operations generate a tremendous amount of noise. Generally, this noise is greater the closer one is to the landing/take-off strip and. decreases the farther away one gets. This noise can cause inconvenience to residents and may also cause structural defects due to noise vibrations. However, certain design factors such as sound-proofing can minimize these effects. Most uses are premissable within certain noise zones but it is strongly encouraged that these design factors be applied in construction. B. ACCIDENT POTENTIAL ZONES (APZ) Accident Potential Zones are a result of the need to protect life and property in I the event of airplane crashes. Generally, these areas are situated closest to the landing or take-off areas which the Department of Defense.recommends remain undeveloped. Within the Accident Potential Zones, there is a Clear Zone, an Accident Potential Zone I and an Accident Potential Zone II depending upon the distance of the property from the air strip. The Clear Zone is the area immediately beyond the end of the runway; the Accident Potential Zone I is 3,000 feet wide and 5,000 feet long; while the Accident Potential Zone II is beyond Accident Potential Zone 1, 7,000 feet long by 3,000 feet wide. Within the Clear Zone all uses which involve development are unacceptable; development in Accident Potential Zone I is normally unacceptable while development in Accident Potential Zone II is encouraged by the Department of Defense to be of very low density.

One-mile radius Radio Frequency Interference Free Zones around receiving antennas are normally desirable; however, the impact on receiving capability of encroachment into the desired Radio Frequency Interference Free Zones must be determined by individual studies. For further information contact: Commander Naval Communication Station Finegayan, Guam Tel. 355-5311 ELECTROMAGNETIC RADIATION (EMR) ZONES Electromagnetic Radiation Zones are areas around transmitting antennas where high density electromagnetic power densities may constitute a hazard to personnel, explosives or fuels, or may interfere with non-military electronic equipment. General guidelines have been developed by the Department of Defense which recommend that land uses with.in a one-mile radius of transmitting antennas be controlled to preclude Electromagnetic Radiation problems. The actual degree of hazard at a specific location, however, must be determined by special studies because the degree of hazard can vary with the type of antenna, radio frequencies transmitted and amount of radio frequency energy radiated. In addition to Electromagnetic Radiation Zones required for high-powered transmitting antennas previously discussed, specialized transmitting facilities such as air navigational aids require isolation in order to operate correctly. The VORTAC is one of these facilities. It requires a 1,000-feet protection area around the facility. For further information contact: Commander Naval Communication Station Finegayan, Guam Tel. 355-5311 EXPLOSIVE SAFETY QUANTITY DISTANCE (ESQD) CIRCLES Explosive Safety Quantity Distance Circles are a result of the storage of explosives such as bombs and ammunition. These circles are set up to accommodate accidential explosions thereby, preventing or reducing injuries and property loss. Explosives are stored in structures called "magazines". Each magazine can store up to 500,000 pounds of TNT. For safety purposes, 3,970 feet is required around the magazine to prevent injuries and property loss. Generally, uses that do'not involve the construction of homes and other habitable structures such as agriculture, conservation, open recreation and roads are permissable within the outer forty percent (beyond 2,382 feet) of the Explosive Safety Quantity Distance Circle. For more detailed informatfon contact: Commander Naval Magazine Santa Rita, Guam Tel. 339-4148 HISTORICAL AND PREHISTORICAL SITES Historical and prehistorical sites are areas on Guam Where past human activity has left structures and artifacts that are highly valued as links with a rich cultural heritage. These areas are particularly important because of their archaeological significance, aesthetic value and fragile nature. Unplanned development can destroy these areas or limit their use as areas for observation, recreation and educational experience. The three elements of historic preservation are historic sites, archaeological sites and architectural sites. Included in historic sites are pre-spanish village areas characterized by a prevalence of artifacts and associated features such as latte stones, rock shelters and mortar stones. Since much of the island's present lifestyle has been influenced by a Spanish heritage, buildings that have survived this colonial era are valuable historic sites. Also, of historic significance are World War II relics that provide fascinating information for both residents and visitors, into the past time of conflict. For further information contact: Department of Parks and Recreation Government of Guam Toto, Guam Tel. 477-9620/21 AQUIFERS RECHARGE AREAS, WATERSHEDS AND WELLS Within the northern and central parts of the island, a layer of freshwater floats upon saltwater and forms a lens. This freshwater is pumped upwards and provides island residents with drinking and irrigation water. The freshwater lens is replenished by rain seeping through the limestone. In the south, water is obtained from reservoirs which hold water from rivers and streams. Rainwater does not seep underground as much as in the north and central areas because the south is composed of volcanic rock. The areas surrounding these streams and rivers are called watersheds which directs rainwater into the streams and rivers. Since aquifer recharge areas, watersheds and wells are critically important in providing water and protecting our water resources, these areas must be effectively managed to prevent water contamination. For further information contact: Guam Environmental Protection Agency Government of Guam Harmon Plaza, Guam Tel. 646-7916 SEISMIC FAULT ZONES Seismic fault zones are those areas that subdivide the island's geologic structure and are potentially hazardous during an earthquake. During the island's geological development, different blocks of land have uplifted and subdivided. Six major blocks are divided by fault lines or geologic.structural subdivision zones. Most seismic activity occurs in the vicinity of these zones. Since geologic activity occurs over such a long expanse of time, the immediate hazard along fault lines is relatively minor. The land is stable enough for most land uses. Further geologic and seismological studies are needed before a more precise determination of the extent of the hazards associated with fault lines is.known. For more information contact: Bureau of Planning Government of Guam Room'403, Pacific News Building Tel. 477-9502 SLIDE AND EROSION ZONES Slide and erosion zones are areas with topographic characteristics.that are liable to create an inconvenience and sometimes disasterous threats to human life if not properly maintained or developed. These are hilly areas with slopes in excess of 15%. Approximately half of Guam's total acreage (43%) nas slopes in excess, of 15%. Steep terrain generally occurs on the island's coastal cliffs, terraces, and southern savannah grasslands. Construction on hillsides can promote erosion which destroys protective vegetative cover, limits lan'd use.- and degrades water quality and visual appearance. Unplanned development can also lead to landslides and increase flood hazards. The weight of structures on steep hillsides can cause unstable soils to "slump" and weaken foundations. In extreme cases, mud slides may cause building damage and/or threaten human life. When ground cover is disturbed or removed during development, exposing the soil, potential for erosion is introduced. As the surface area available for absorption of rainwater is reduced by impervious surfaces (roofs, roadways, parking lots, etc.), runoff is increased and the potential for erosion also increases. As a rule, slopes are more easily eroded than level lands; the extent of erosion during construction and prior to soil stabilization is substantially increased on steep terrain. Septic tanks and leaching fields installed on steep slopes are more susceptible to failure than similar installations in more level landscapes. Where provisions are made for the public power, water, telephone, or sewage systems, the difficulties and costs are significantly greater on steep slopes. In addition, the acreage requirements for roads and also for structures increase with slope. In short, land cannot be used as efficiently on steep slopes as on level land. Efficiency is related to cost and some cost of developing land on steep slopes must be borne by the public, as local government must maintain roadways or other utilities or when erosion, water sedimentation, or slide damage occurs. For more information contact: Bureau of Planning Government of Guam Room 403, Pacific News Building Tel. 477-9502 FLOOD HAZARD AREAS Flood hazard areas are low lying areas which retain the overflow of runoff from the natural and developed drainage systems during periods of persistant'rainfall. If improperly used, flood hazard areas can become problem areas as a result of deterioration of flood-damaged structures and the recurrence of public expense for relief and repair of flood-damaged facilities and failing sanitary systems. In a lot of cases, these flood hazard areas are level and because level land is in high demand on the island, much development has already occurred in or encroaches upon flood hazard areas. There are presently performance standards developed by the Government of Guam in compliance with the requirements of the National Flood Insurance Program and by -Executive Order 78-294 For further information contact: Department of Land Management Government of Guam Agana, Guam Tel. 472-8851/2/3 SEASHORE RESERVE The seashore reserve is defined by P.L. 13-154 as "that land and water area of Guam extending seaward to the ten fathom contour (60 ft.), including all islands within the Government's jurisdiction except Cabras Island and those villages wherein residences have been constructed along the shoreline prior to the effective date of the Seashore Act (1974), and extending inland to the nearer of the following points: 1) From the mean high water li-ne for a distance on a horizontal plane of 10 meters (33 ft.). 2) From the mean high water line to the inland edge of the nearest public right-of-way. The law basically intends to protect the seashore reserve through the review of development proposals by the Territorial Seashore Protection Commission. For further information contact: Department of Land Management Government of Guam Agana, Guam Tel. 472-8851/2/3 WETLANDS Wetlands are unique parts of the island's natural land area. They include swamps, marshes, mangroves and river valleys that are constantly covered with water. They support aquatic plants and animals. Wetlands also act as a source of freshwater or as floodplatns. Most importantly, they are a nursery ground for juvenile plants and animals. The mangrove wetlands are not only a wildlife habitat, but are also useful for shoreline protection from wind and waves. Development within wetlands should not involve their filling or uses which adversely affect water quality or wildlife. For more information contact: Department of Land Management Government of Guam Agana, Guam Tel. 472-8851/2/3 MARINE PRISTINE ECOLOGICAL COMMUNITIES Marine Pristine Ecological Communities are relatively undisturbed near-shore and off-shore areas that provide a rich variety of habitats for rare aquatic and marine species. They include mangrove swamps, seagrass beds, reef channels and submarine cliffs and should be protected for their educational, scientific and aesthetic values. For further information contact: Department of Agriculture Government of Guam Mangilao, Guam Tel. 734-3941 CORAL REEFS Coral reefs are geological formations created by living marine organisms which separate the shore from the deeper ocean. During low tide, these reefs may be exposed to a great extent. Coral reefs provide protection of the shoreline, especially beaches from storm waves and erosion. They also provide recreational areas for water sports and fishing. It is for these reasons that development on land and within near-shore areas be managed to prevent damage or destruction of coral reefs. For further information contact: Department of Agriculture Government of Guam Mangilao, Guam Tel. 734-3941 LIMESTONE FORESTS The limestone forests of Guam are so named because they grow in minimal soil upon the northern limestone plateau. They are a limited resource because land development has cleared most of the forested areas. They can never be reforested to their original condition because newly introduced weeds and shrubs prohibit the reestablishment of native plants and animals. Limestone forests are characterized by large trees which shade the lower vegetation. These areas nust be protected to support wildlife, recreational, and educational uses.
