In addition, the owner of #9 Orleans Avenue has reported frequent water problems in his basement and has installed several sump pumps • which currently discharge water onto Orleans Avenue where it connects overland to the Orleans Avenue drainage system. In an effort to reduce flooding in the Orleans Avenue neighborhood, the city of Salem retained New England Civil Engineering to investigate the drainage system and provide a list of recommendations to improve the reported flooding and groundwater problems. Project Understanding: The"Orleans Avenue Drain Outfall' is located to the rear of.property #17 Orleans Avenue and appears to be located within the boundary of a City of Salem drainage easement. The drainage.system tributary to this outfall begins in Orleans Avenue with two catch basins that convey drainage through the parking area at #276 Highland.Avenue (Mattress Giant property), and through the backyards of the odd side of Orleans Avenue. The drainage previously discharged through an outfall (OF1) but has been redirected where it currently discharges through a hole in MI-13 (labeled as OF1A). We understand that MI-13 was modified by previous City of Salem efforts'to address flooding concerns in this area. From the current point of discharge (OF1A), Orleans Avenue drainage follows a drainage channel and passes through two concrete culverts before it ultimately reaches the headwaters of the Forest River. Refer to project area Map in Appendix A and profile views in Appendix B. • During periods of heavy rainfall, standing water has been reported and observed in the rear parking lot of #276 Highland Avenue. The owner,of #9 Orleans Avenue has reported frequent groundwater problems In his basement and currently pumps water onto Orleans Avenue where it enters the closed drainage system. During periods of heavy rainfall when the Mattress Giant property has standing water, sump pump discharge from #9 Orleans Avenue is directed into the surcharged drainage system and in effect is pumped in a circle. Recently the owner of #9 Orleans Avenue has redirected his sump pump discharge to the drain behind his house in the City of Salem Easement. • WATER RESOURCES - BURIED INFRASTRUCTURE-PUBLIC WORKS - CONSTRUCTION ADMINISTRATION - LAND DEVELOPMENT Study Related Investigation: In September and October, 2008, the main drain from MH2 to CB3 was cleaned numerous times and,internally inspected with closed circuit televised (CCN) camera. In an attempt to remove roots, sub-contractor Thomas Mackey & Sons (Mackey)jetted the pipe and dragged increasing diameter"cages"through the pipe to dislodge roots. Use of a root cutter was not recommended by Mackey due to the poor condition of some of the joints along the section. The results of the CCN pipeline inspection are summarized in Appendix D. • NECE completed a level survey of the main drain using a local datum to determine the relative elevations of all culverts and drain outlets. The results of this level survey are incorporated into the profile plan in Appendix B. Findings: The Orleans Avenue drainage system has several significant problems which limit its hydraulic capacity: 1) The existing drain.outfall (OF-1A) is positioned approximately two feet below the inlet elevation of the downstream drainage culvert (IN1). As.a result, the outfall Is constantly submerged and is therefore limited in its ability to store and convey rainfall runoff. 2) The existing drain pipe from the Mattress Giant manhole (MH2) to the outfall (ORA) was installed with minimal, bordering on reverse, slopes. The average slope along this reach is 0.0037 ft/ft. As a result, the velocities through this drain pipe are slow and make the pipe prone to sedimentation problems. 3) Heavy root intrusion exists in a section of the drain pipe behind the properties of #9 and • #11 Orleans Avenue, approximately 60 linear feet. Several large Weeping Willow trees exist in this area and are the likely source of the root problems. The presence of roots in the pipe compounds problem #2-and increases the likelihood of sedimentation buildup. Specific Findings: Pine section between MH2 and CB3: Root'intrusion was observed in every pipe joint (7 foot pipe sections) from approximately 85 to 143 feet downstream from MH2. These were partially cleaned out in September, 2008. However, there are severe roots at approximately 143' downstream from MH2 (115' upstream from C133) that could not be removed with the methods employed by Mackey at that time. NEW ENGLAND CMI.ENGINEERING CORP. Page 2 of 4 • • Pipe a section between CB3 and OF1: The pipe that conveys flow from MH3 to OF1 appears to have settled, has negative slope, and is covered by dense vegetation, and should be permanently abandoned. The pipe section between CB3 and MH3 (OF1A) appears to have settled since installation, due to construction and grading of the #19 Orleans Avenue property, leaving OF1A approximately 2 feet lower than the previous outfall OF1 and the downstream culvert inlet IN1. Compounding this problem, the drainage channel downstream of OF1A is choked with large rocks, trash, and debris partially blocking flow in several areas. • Recommendations There are several options to improve drainage and flooding problems in this area that vary in probable cost and potential benefit.. ,1) High Cost/ High Benefit: A. Pipe section between MM2 and CB3: Remove and replace the approximately 60 feet of pipe with heavy root intrusion and externally seal all new joints with concrete. Consider removal of two Weeping Willow trees in this area that are the likely source of root problems. B. MH Remove existing manhole which serves as outfall OFiA, replace with flared end outfall and riprap erosion protection, and plug 12" pipe out to OF1 with grout. C. Culvert IN1-OF2: Remove and reset or replace existing culvert (approximately 20 feet of 18" RCP) in the same location but at approximately 2 feet lower elevation. D. Channel between MH3 and OF3: • Perform maintenance and cleaning of open drainage channel from MH3 to IN1, to remove obstructions and improve drainage to culvert IN1-OF2. Consider maintenance and cleaning of drainage channel between OF2 and IN2 to improve drainage in this area. 2 i h C Hi h Benefit. A. Pipe section between MH2 and CB3: Remove and replace the approximately 60 feet of pipe with heavy root intrusion and externally seal all new joints with concrete. Consider removal of two Weeping Willow trees in this area that are the likely source of root problems. NEW ENGLAND CIVIL ENGINEERING CORP. Page 3 of 4 • B. MH3: Replace approximately 80 feet of pipe between CB3 and MH3 with new 12" drain pipe installed at minimum slope so outfall is located at a higher elevation than existing downstream culvert inlet IN1. Remove existing manhole which serves as outfall OF1A, replace-with flared end outfall and riprap erosion protection, and plug 12" pipe out to OF1 with grout. C. Channel between MH3 and OF3: Perform maintenance and cleaning of open drainage channel from MH3 to IN1, to • remove obstructions and improve drainage to culvert IN1-OF2. Consider maintenance and cleaning of drainage channel between OF2 and IN2 to improve drainage in this area. 3) Moderate Cost / Moderate Benefit: A. Pipe section between MH2 and CB3: Remove and replace 2 pipe sections adjacent to the major blockage in the yard of #11 Orleans Ave and externally seal all new joints with concrete. Provide drain stub to edge of City drainage easement to the rear of #9 Orleans Avenue to provide a discharge location for his sump pump. B. Channel between MH3 and OF3: Perform maintenance and cleaning of open drainage channel from MH3 to IN1, to remove obstructions and improve drainage to culvert IN1-OF2. 4) Low Cost / Low Benefit: A. Pipe section between MH2 and CB3: Run root cutter upstream from CB3 to remove major blockage. This may result in root cutter becoming lodged in pipe and requiring excavation removal. B. Channel between MH3 and OF3: Perform maintenance and cleaning of open drainage channel from MH3 to IN1, to remove obstructions and improve drainage to culvert IN1-OF2.
