*Installation of pre-treatment features will vary based upon type. Similarly, installation timeline will range with type and could occur at excavation and mass grading, curb work or at finishing grade. Given pre-treatment features are typically integrated with the LID inlet coordination amongst multiple sub-contractors is sometime needed. The following details steps for various pre-treatment types:

'''Key Inspection Points:'''

'''Key Inspection Points:'''

*Verify that the correct pre-treatment device (jellyfish filter, vegetation, curbing, etc.) is being installed.

*Verify that the correct pre-treatment device ([[pretreatment|jellyfish filter]], [[vegetation]], [[curb cuts|curbing]], etc.) is being installed.

*Verify that all components of the pre-treatment device are installed

*Verify that all components of the pre-treatment device are installed

*Verify correct size and location of pre-treatment device.

*Verify correct size and location of pre-treatment device.

*Using wrong concrete forms if concrete curbs are part of pre-treatment.

*Using wrong concrete forms if concrete curbs are part of pre-treatment.
