This is a service / maintenance or supply contract in Chelmsford, Massachusetts. Contact the soliciting agency for additional information.

The Town of Chelmsford, through its Engineering Division, is seeking proposals from qualified professional engineering consulting firms to develop a watershed analysis for three subbasins, Deep Brook, Black Brook East, Area to Lowell within the Town. Background Chelmsford, incorporated in 1655, is located in northern Middlesex County approximately 24 miles northwest of Boston. The town is approximately 23 square miles in size and has a residential population of roughly 33,800. The majority of the town is residentially zoned with most business and commercial type properties located along the Route 129 and Route 110 corridors. Nearly all of the town has access to the town's public water system which is supplied via several wells. The Town is serviced by 3 independent municipal entities that are formed as water districts as follows: The Chelmsford Water District, North Chelmsford Water District and East Chelmsford Water District. The town is located within two major regional watersheds, the Merrimack River watershed in the northern portion of town and the Sudbury-Assabet-Concord (SuAsCo) River watershed in the southern portion of town. These watersheds are home to many different natural resources. Some of the more significant waters in town include Freeman Lake, Hart Pond, River Meadow Brook, Stony Brook, Beaver Brook and Black Brook. Chelmsford is regulated by the EPA as an urbanized area and is permitted to discharge stormwater runoff to these natural resources through an approved NPDES MS4 Phase II permit. The majority of the town's regulated stormwater discharges are associated with either town owned roadways or town owned properties. PROJECT SCOPE Below is a detailed summary of the anticipated tasks and services required to complete the master plan and should be viewed as the basic project framework. Consultants are strongly encouraged to expand on these tasks where applicable in order to include any additional services that they would consider to be an essential element of a successful Stormwater Management Master Plan. 1) Data Information Gathering Gather and review all applicable information and data available including, but not limited to: existing capital improvement projects, operation and maintenance efforts, regulatory requirements, town-wide water quality issues, stormwater infrastructure inventory, survey site to collect elevation data of flooding areas. Perform a limited amount of field work (as identified by the Bidder) to assess the accuracy and completeness of the current GIS stormwater mapping layers. In field survey of existing known flooding locations as indicated in attachment 2. 2) Tributary Catchment Area Identify and evaluate the tributary catchment area for all three subbasins. Perform a condition assessment of the existing stormwater mapping based on completed field work. The assessment shall utilize the results of the project field work to extrapolate the current accuracy and completeness of the town wide GIS stormwater mapping. 3) Hydraulic Modeling Develop Hydraulic modeling of drainage area to see if the drainage infrastructure is undersized, culverts, pipes, and stream channels. This should include base flow conditions of streams within each subbasin. Modeling of ground water to be identified by the Bidder. 4) Deliverables Prepare and present a DRAFT report to be reviewed by the RFP Review Committee. Based on input by the Review Committee, prepare a FINAL Report for presentation at a Public Meeting. The FINAL report shall include the stormwater assessment, potential solutions, estimated construction costs, and preliminary recommendations for coordination of programs, for organizational changes, and for next steps to implement the plan. 5) Additional Tasks and Services Recommended The consultant shall include and detail any additional work or services that they believe are essential to the completion of a comprehensive Watershed Analysis. 6) Meetings A detailed outline of the type and number of meetings anticipated to complete the project shall be provided. These meetings shall be included in the proposed project fee. The goal and objective of this project is to develop a comprehensive assessment of the area contributing stormwater flow to each site by verifying tributary catchment delineation, determine the volume of stormwater and identify deficiencies in the existing infrastructure as they relate to system capacity. Propose solutions to known flooding issues after assessments have been completed, including estimated construction costs and timeline for completion. To develop a means and methodology for groundwater solution within each subbasin. The final assessment will show a hydraulic model for each site to evaluate whether the existing drainage infrastructure is able to handle the flow from various rain events.
