Purpose These requirements for site plans have been prepared to assist developers, builders, architects, engineers, and others in securing the necessary approvals from the Boston Water and Sewer Commission. In addition, details and guidelines relative to the requirements and information necessary for the site plan drawings are included. Click here for a site plan review checklist.
Authorized Approval All site plans submitted to BWSC for review The location of all utilities in the street: water, sewer, storm drain, telephone, gas, electric, steam and cable television must be shown to scale on the site plans. A north arrow is required on the site plan. Review and Approval The average time span for BWSC review and approval of a site plan is one week to ten days. A longer period of time may be necessary if the project is large and complicated or the submission is inadequate. Narrative Letter A narrative letter briefly describing the Drawing Requirements One print is needed for preliminary review and comment by BWSC. Five site plan drawings should be submitted for final review and approval. Two approved signed prints will be retained by the BWSC, one for the record file and the other for the BWSC Investigating Inspectors. All final site plan submissions must be accompanied with an AutoCad Release 14 or higher disk. Drawing must be in compliance with the BWSC CAD Standards for Site Plans (Design and As-Builts). When submitting Site Plan Record Plan Drawings to Engineering Customer Service, please make sure that there are no XREFS included in the Drawing. You can choose to bind a XREF to a drawing using either the Bind option or the Insert option. The option you choose determines how the file names are merged from the reference file into the drawing file. Using Bind will avoid overriding existing block definitions. If you use Insert, the symbol names are merged into the drawing file. If duplicate symbols exist, AutoCAD uses the symbols already defined in the local drawing and overrides them. If you are unsure whether your drawing contains duplicate symbol names, it is recommended that you use Bind, not Insert. A 5"x5" box reserved for BWSC use only shall be required on each drawing. The official street number of locations are required on the drawings. The City of Boston Building Department street numbering form must be filed with the Inspectional Services Department. Submission of this form must be included with the site plan. The WARD and PARCEL NUMBER of the lot The Owner's Name, Address and Telephone Number are required on the site plan. The address of the site including Extended Zip Code is also required. The estimated sizes of all public street and sidewalks openings that will be required for Fire Pipes Any request for installation of a new fire pipe |
Inspections After the site plan is signed by the Chief Engineer or his designee, a General Service Application must be filled out and signed by the owner of the property or the owner's agent prior to the time of installation of domestic water service, fire pipe service, building sewer or building storm drain connections. A deposit based on the size of the water service or fire pipe connection and sewer and drain connections must accompany the GSA submission. Upon receipt of the appropriate deposit, the Commission will establish a water and sewer account and assign an account number to the property. An inspection fee will be charged for each water and sewer connection. Twenty-four (24) hours advanced notice is required for inspection scheduling. If any inspection date is scheduled on the weekends, holiday or after regular work hours, and the contractor fails to notify the BWSC inspectors of cancellation in advance, an additional inspection fee will be charged to the contractor when the job is subsequently rescheduled. All construction work performed on BWSC systems or construction work performed on systems whose ownership may be transferred to the BWSC must be inspected by a BWSC Construction Inspector at the developers expense. The contractor will be charged the current BWSC rate per diem based upon estimated work days through the completion of the project. The Manager of Engineering Services will make this determination. These payments shall be made through the Engineering Services Department. Upon completion of the work a refund or an additional bill will be issued based upon actual working days. The contractor must notify, in writing, the Director of the BWSC. Construction Division, seven (7) days prior to the beginning of construction. This will allow the Commission sufficient time to schedule field inspection. Sewer Connections When there is a separate sanitary sewer and a separate storm drain in the street, the building sewer must be connected to the sanitary sewer and the building storm drain can connect to the storm drain. It is however mandatory to retain stormwater on site whenever possible. Where there is a combined sewer only in the street, and a BWSC storm drain is not accessible, installation of a drywell is required. A percolation test must be taken by a Registered Professional Engineer or Registered Sanitarian to determine if the soil is suitable for dissipation of storm water runoff. If the proposed site is in wetland or within 100 feet of a wetland or water, an Order of Condition must be obtained from the Boston Conservation Commission in order to make water or sewer connections to BWSC facilities. If the proposed site is located in an area where BWSC sewer facilities are not accessible but MWRA facilities are available, the applicant must fill out an Application/Permit to Connect to the Sewerage System of the Massachusetts Water Resources Authority. In accordance with the Massachusetts Water Resources Authority (MWRA) Sewer Use Rules and Regulations, the amount of time in advance the Toxic Reduction and Control Department (TRAC) requires is a minimum of ninety (90) days to process a Sewer Use Discharge Permit Application for a new user. TRAC does issue temporary permits in some cases so that industry may begin operation once the temporary permit has been issued, which usually takes 30-45 days. However, it is best for the industry to submit the application 90 days in advance so TRAC can issue a more specific permit before operations begin. Permit Renewals For permit renewals, the current regulations, 360 CMR 10.062(2), state that industry must submit a renewal application no later than thirty (30) days before its current permit expires in order for that permit to remain in effect after its expiration date. It should be noted that this is an area of the regulations that most likely will be revised in the future to require renewal application submittal earlier than 30 days in advance.
