We and our subcontractors are subject to a variety of local, state, federal and other environmental, health and safety laws, statutes, ordinances, rules and regulations, including those governing storm water and surface water management, discharge and releases of pollutants and hazardous materials into the environment, including air, groundwater, subsurface and soil, remediation activities, handling of hazardous materials such as asbestos, lead paint and mold, protection of wetlands, endangered plants and species and sensitive habitats and human health and safety.
The particular environmental requirements that apply to any given site vary according to multiple factors, including the site's location and present and former uses, its environmental conditions, the presence or absence of endangered plants or species or sensitive habitats and environmental conditions at nearby or adjoining properties.
There is no guarantee that we will be able to identify all of these considerations during any pre-acquisition or pre-development review of project sites or that such factors will not develop during our development and homebuilding activities. Environmental requirements and conditions may result in delays, may cause us to incur substantial compliance, remediation and other costs and can prohibit or severely restrict development and homebuilding activity in certain areas, including environmentally sensitive regions or areas contaminated by others before we commenced development. In addition, in those cases where an endangered or threatened plant or species is involved and agency rulemaking and litigation are ongoing, the outcome of such rulemaking and litigation can be unpredictable and, at any time, can result in unplanned or unforeseeable restrictions on, or the prohibition of development in, identified environmentally sensitive areas. In some instances, regulators from different governmental agencies do not concur on development, remedial standards or property use restrictions for a project, and the resulting delays or additional costs can be material for a given project.
Certain environmental laws and regulations also impose strict joint and several liability on former and current owners and operators of real property and in connection with third-party sites where parties have sent waste. As a result, we may be held liable for environmental conditions we did not create on properties we currently or formerly owned or operated, including properties we have developed, or where we sent waste. In addition, due to our wide range of historic and current ownership, operation, development, homebuilding and construction activities, we could be liable for future claims for damages as a result of the past or present use of hazardous materials, including building materials or fixtures known or suspected to contain hazardous materials, such as asbestos, lead paint and mold. A mitigation plan may be implemented during the construction of a home if a cleanup does not remove all contaminants of concern or to address a naturally occurring condition such as methane or radon. Some homebuyers may not want to purchase a home that is, or that may have been, subjected to a mitigation plan. In addition, we do not maintain separate insurance policies for claims related to hazardous materials, and insurance coverage for such claims under our general commercial liability insurance may be limited or nonexistent.
Pursuant to such environmental, health and safety laws, statutes, ordinances, rules and regulations, we are generally required to obtain permits and other approvals from applicable authorities to commence and conduct our development and homebuilding activities. These permits and other approvals may contain restrictions that are costly or difficult to comply with, or may be opposed or challenged by local governments, environmental advocacy groups, neighboring property owners or other interested parties, which may result in delays, additional costs and non-approval of our activities.
From time to time, the EPA and similar federal, state or local agencies review land developers' and homebuilders' compliance with environmental, health and safety laws, statutes, ordinance, rules and regulations, including those relating to the control of storm water discharges during construction. Failure to comply with such laws, statutes, ordinances, rules and regulations may result in civil and criminal fines and penalties, injunctions, suspension of our activities, remedial obligations, costs or liabilities, third-party claims for property or natural resource damages or personal injury, enforcement actions or other sanctions or additional requirements for future compliance as a result of past failures. Any such actions taken with respect to us may increase our costs and result in project delays. We expect that increasingly stringent requirements will be imposed on land developers and homebuilders in the future. We cannot assure you that environmental, health and safety laws will not change or become more stringent in the future in a manner that would not have a material adverse effect on our business, prospects, liquidity, financial condition and results of operations.
We have provided environmental indemnities to certain lenders and other parties. These indemnities obligate us to reimburse the indemnified parties for damages related to environmental matters, and, generally, there is no term or damage limitations on these indemnities.
