The common benefits are usually obtained by CBAs, which can take the form of a private agreement between the developer and the local community, a contract between the developer and the government, or a three-way agreement between the developer, the government and the community. In addition to CEAs, the benefits of COMMUNITY policy can be achieved through social contracting clauses, as well as other policies and legislation. In short, the benefits of the Community are the additional social, economic or environmental benefits that are granted to local communities through the use of infrastructure funds. These benefits may include local employment and training opportunities for disadvantaged people in the labour market, social markets for the purchase of goods and services from local or social enterprises, improvement of public space or other benefits identified by the Community. CBAs contribute to the completion of public projects on time and on budget and provide benefits to the municipalities in which they are built. CBAs ensure that taxpayers` money is reinvested in local communities and that there is a lasting legacy of experience, skills, training and employability among the workers who built the project. If you adapt CBAs to specific community needs, they`re more successful, says Kiran Alwani, a political analyst at the Mowat Centre. “Communities, for example, always want to make sure that their voices are heard, and they are not only consulted or engaged in the traditional sense, but that they engage in the process,” she says. In fact, the agreement depends on establishing a long-term relationship – that is, there will never be a single CBA. Since a CBA is a legally binding contract, it can only be applied by the parties who signed it. CBAs included in development agreements can be implemented by government and community groups.  To date, there is no case law on the validity and applicability of CBAs. The 1993 contract, similar to Donald Trump`s CBA, for the New York City Riverside South project was the subject of an expert opinion by the 2008 New York Appellate Division, but the court found that the terms of the contract had expired.
