    I am not sure if I fully understand your question, but I think this is the ans you are looking for.

    Infill land development is taking empty space between building and using it in productive manner. It does not necessarily have to be a building, it can be a park or small gathering area. 

    Brownfield is land that has hazards elements which can damage the environment, however it can be repurposed into usable land through treatment... ie gas stations, old chem factories, landfills ect

    I did some research on the infill and found out that an infill site sometimes can be a brownfield. 

    Wikipedia defines infill as “the use of land within a built-up area for further construction; especially as part of a community redevelopment or growth management program or as part of smart growth. It focuses on the reuse and repositioning of obsolete or underutilized building and sites.”

    Infill development is the process of developing vacant or under-used parcels within existing urban areas that are already largely developed.

     

    What is Infill and Redevelopment?

    There are various definitions of infill and redevelopment. The American Planning Association describes infill development as redevelopment that, “optimize[s] prior infrastructure investments and consumes less land that is otherwise available…” Infill development and redevelopment can result in:

    • Efficient utilization of land resources
    • More compact patterns of land use and development
    • Reinvestment in areas that are targeted for growth and have existing infrastructure
    • More efficient delivery of quality public services

    The Maryland Sustainable Growth Commission offers three definitions of infill, redevelopment, and revitalization. The following is an adaptation of these definitions.

    • Infill refers to the development of vacant parcels within previously built areas. These areas are already served by public infrastructure, such as transportation, water, wastewater, and other utilities.
    • Redevelopment describes converting an existing built property into another use. Ideally, redevelopment aims for better use of the property that provides an economic return to the community. For example, a vacant property may be converted to a mixed-use development that combines residential and commercial uses.
    • Revitalization means instilling new life and vitality into a community through activities such as infill and redevelopment. Revitalization activities may include reusing or renovating buildings, improving building façades, streetscaping to beautify an area, and/or conducting incentive-based or preservation-based economic development tools to leverage local assets.

    Infill development can occur on brownfield sites with potential environmental issues like a small isolated parcel with former gas station, on the site of a large, abandoned manufacturing facility, or on a declining commercial-strip mall location, or “greyfield.” This development strategy aims to fill in “gaps” in communities, playing a key role in efficient land-use, community revitalization, and economic development. Infill utilizes existing infrastructure, directs reinvestment to high-priority growth areas, and has the potential to generate jobs. Infill development also provides a smart alternative to sprawling development in undeveloped, greenfield areas that lack infrastructure are not designated for growth.

    Pros of Urban Infill

    • Ability to utilize existing infrastructure/facilities
    • More transportation options for those that will be utilizing the proposed use - urban infill means a higher population and encourages cities to create more city resources, such as public transportation.
    • Businesses are closer to residents and existing facilities and vice versa - located close to things like grocery stores, schools, doctors, and work reduces the cost of living for people.
    • Possibility of utilizing historic structures and/or mature landscaping
    • Investing in the existing community
    • Possibility of incentives provided by the municipality
    • Reduction in the municipal costs associated with maintaining suburban areas
    • Gives the Community a Face Lift - Urban infill provides beautiful new buildings, which in turn improves the community’s appearance and reputation and encourages people and businesses to return to the area.
    • Lowers City Costs - less money needs to be spent on everything from creating roads, providing police protection, and utility services. The city will be bring in more annual tax incom

    Cons of Urban Infill

    • Unique and increased project constraints
    • Can be more costly than suburban development
    • Zone Change or Use by Special Review (“USR”) requirement if current land use classification does not fit proposed land use classification (and possible increased buffering requirements if neighboring uses differ from proposed use)
    • Heightened expectations/concerns from businesses and residents in areas surrounding the new development
    • Possible need to upgrade and/or relocate existing infrastructure to support the new development, including on-site and off-site utilities
    • Other barriers to Infill Development - The community needs to recognize and overcome impediments such as:
    1. neighborhood opposition
    2. financing challenges
    3. inflexible building code and development regulations
    4. lengthy permit processes
    5. substandard infrastructure
    6. difficult land assembly
    7. site contamination and other conditions
