    Lancaster highway department resurrects GIS

    The Lancaster highway department is resurrecting the GIS system to transfer over old data and store future collected data for the purpose of identifying and recording any work done to a box culvert, bridge, drainage ditch, catch basin, etc. According to Highway Superintendent Dan Amatura, the system will allow the town to eat away at drainage issues, record size of pipe openings, record of last clearage, locate designated sign positioning, etc.

    A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. GIS allows it’s user to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.

    The town has an incredible wealth of knowledge that is now stored in minds, memories or in paper records that are difficult to cull out and make sense of. This will allow work records to be entered daily into a computerized system and not lost over time. The town is working with the Wendel Duchsherer engineering firm. Along with Amatura, Duchsherer representatives Scot Rybarczyk (drainage) and Orest Ciolko (GIS) gave a presentation on the benefits of the system and on how it could be used to integrate information with other departments and utilized by the Town Planning and Zoning Boards.

    Favoring the use of the GIS system, Town Assessor Dave Marrano spoke on the interfacing that could take place with his departments to better analyze and evaluate properties. “We could see what’s on the property that could impact assessment – wetlands, additions and their placements, environmental issues, etc. By using overlays flood maps, school districts and other pieces of information could be integrated into the system. Hamburg and other municipalities use the system and find it to be of much value.”

    Finding this to be a valuable tool, it is hoped that the GIS information will be posted on the town’s web site in the future and used by the public as well – as is currently done in the Town of Hamburg.

    Declaring, “We are looking for the big rocks, big things that can provide help with fairly low cost,” Duchsherer representatives gave a PowerPoint presentation on two drainage examples that Amatura is currently using the system to map out and used for resolution.

    Walden Pond Park

    Observations:

    • Under existing conditions, the baseball fields in Walden Pond Park flood and the flooding remains for many days.
    • A drainage pipe was installed in the park to divert flow to the south. Unfortunately, during floods there is no capacity in the drainage ditches to the south and the pipe sits filled with water.
    • Storm sewers along Peppermint Road to the north of the Park were observed during large flooding events. Water was flowing into these sewers with no flooding above the catch basin rims.
    • Survey data collected showed that the lowest elevations in Walden Pond are still higher that the elevations of the storm sewer along Peppermint Road.

    Next Steps:

    Investigate the possibility of developing a drainage swale at the west edge of the Park and connect this to a new storm sewer running north to Peppermint Road. Easements for locating a new storm sewer in private property would be required.

    Slate Bottom Creek

    Brunck Road has a history of drainage problems. The problem has become significantly worse with the redirection of the creek at Brunck Road and through years of surrpounding residential construction.

    Observations:

    • The section of Slate Bottom Creek between Chestnut Court and Brunck Road is home to a number of beavers that are actively constructing dams across the creek. Water elevation jumps with beaver dams. Flow is restricted through these damns and water surface elevation increase upstream of these damns. This increase in the water elevation can increase flooding.
    • Three large beaver dams were noted. The one is large enough to increase elevation by one foot and creates a waterfall. The second creates a large creek blockage flow and a pond just upstream of the damn. The third is the smallest but will grow over time, and at present restricts flow.
    • There are numerous footbridges that cross the creek in the area. The great majority of these bridges do not impede flow, but one bridge is constructed of a series of small culverts and is greatly undersized. It is hoped this footbridge will be removed as here is a newer footbridge just downstream of this one.

    Next Steps:

    The Town needs to remove the source of the problem, the beavers. Individual residents can ask for permits to remove the nuisance beavers. The Town can also ask for a permit based on flooding at Brunck Road, but it (permits) will be more difficult to obtain.

    After permits are obtained, someone can be hired to trap the beavers, or the Town can wait until November for trapping season. During trapping season, the Town may be able to get someone to trap beavers for free as the trappers could then keep the pelts.

    After trapping is complete, the Town can apply for a permit (DEC) to breach the dams.

    Maybe, Donna Lukowski and her Brunck Rd neighbors will eventually be relieved of their drainage issues.

    I believe the Chippewa beavers weren't interested in the erection of dams. They were interested in an erection of another kind.

    Amatura seems very commited to assist Lukowski in getting flooding and drainage relief.

    This would not have been a problem had the town not redirected the creek 30+ years ago.

    This is a classic example of, "the town creates the problem, the residents complain, the town blames the residents." Gary, I hope you don't mnd that I stole this from you, but geez it fits so much of how the town has screwed up and when the resients do complain they are labeled NIMBY'S, obstructionists, cave dwellers, etc., etc.

    Hey gorga and yaksplat, I like the humor exchange.
