NYC DEP records requests provide water and sewer information that can be essential before design, permitting, excavation, or due-diligence work begins. DEP currently uses PARIS for requests involving sewer drainage plans, water and sewer maps, sewer as-built drawings, tap cards, sewer cards, and other records tied to defined project scopes.
A records request is most useful when it is connected to a specific project question. The project team should identify what it is trying to confirm, such as an existing tap, sewer connection, fronting main, drainage plan, or sewer location. A tap card helps document a property’s water-service connection, a sewer card helps document the property’s sewer connection, and a sewer as-built drawing shows how existing sewer infrastructure was actually constructed. Understanding what each record can show makes it easier to request the right information before design or filing begins.

DEP’s current records guidance asks for a project description and generally a site map or plan. A tax map or aerial photograph with street names can be used when a site plan is not available. Requests covering 12 or more blocks require a memorandum of understanding under the current instructions.
For certain engineering records, if the requester is not a PE or RA, DEP also requires an engineering cover letter describing the project and how the requested records will be used. City agency work can use the alternative documentation identified by DEP.
Existing maps and cards can reveal infrastructure that changes design assumptions before a permit is filed. A missing or unexpected sewer connection, water tap, drainage-plan condition, or main location can affect Site Connection Proposals, water-service design, backflow plans, excavation, and construction logistics.
DEP records should be treated as one source of project information. The design professional may still require field verification, survey, testing, dye testing, utility mark-outs, or other investigation before relying on an existing condition for construction.
DEP’s current guidance matches record types to project scopes. For example, Site/House Connection Proposal requests can receive sewer cards, drainage plans, and sewer as-builts, while water-service or backflow requests can receive water maps and tap cards. Drilling or excavation requests can receive water maps and sewer as-built information.

NYC Department of Environmental Protection (DEP) requirements can affect property owners, developers, business operators, design professionals, contractors, and project teams when work involves water or sewer connections, hydrants, backflow protection, stormwater, wastewater, asbestos, air emissions, construction noise, drilling, records, violations, or other environmental requirements administered by DEP.
Before relying on a filing path, the project team should confirm the regulated activity, existing infrastructure and property records, required DEP program, current portal or submission method, licensed professional or trade requirements, inspections, testing, and related DOB, DOT, NYS DEC, FDNY, or OATH coordination.
At SLK Buildings, we assist with NYC DEP permit expediting, agency filings, Site Connection Proposals, sewer and water coordination, hydrant work, backflow, stormwater, drainage, wastewater, asbestos, air, noise, drilling and excavation coordination, records research, violations, hearings, and related multi-agency project requirements within the confirmed service scope.
Whether you are beginning a new DEP application, responding to agency comments, researching existing water or sewer conditions, coordinating licensed professionals and contractors, correcting a compliance issue, or carrying a DEP approval into related construction permitting, SLK Buildings can help organize the records, filings, coordination, and next actions needed to move the project forward.
SLK Buildings provides free educational content to help property owners, developers, business operators, design professionals, contractors, and project teams understand NYC DEP permitting, filing systems, water and sewer approvals, stormwater, environmental compliance, inspections, records, and related agency requirements.
For those who prefer professional assistance, SLK Buildings is available to coordinate DEP application strategy, filing preparation, portal submissions, agency comments, records research, licensed-professional and contractor coordination, approval tracking, violation response, and related NYC agency requirements that may affect the property or project.
