Halfmoon Lake Watershed - Based Management Plan Implementation – Phase 1

2026-11-03

1 . Develop a Site Specific Project Plan ( SSPP ) that will include all aspects of data collection and modeling for each of the above - referenced three ( 3 ) site locations as identified in the HMLA WBMP . This will include , but not be limited to , watershed Best Management Practice ( BMP ) phosphorus load reduction modeling . 2 . Develop conceptual BMP designs , estimated cost of materials , and implementation costs for each of the three ( 3 ) sites . These conceptual designs will be reviewed with NHDES Watershed Assistance Section ( WAS ), landowners , HMLA , and NHDES for comment . After review , address comments to prepare the final BMP designs to be issued to landowners , HMLA , NHDES , and WAS . 3 . Meet all procedural requirements to provide the legal authority to implement BMPs on each of the three ( 3 ) sites . Obtain all necessary town , state , and federal permits for the Site . Prepare Operation and Maintenance ( O & M ) plans with landowners for the site to ensure longterm success of implemented BMP designs . 4 . Provide assistance with developing construction bid documents , and then supervise construction of the designed and permitted BMPs to mitigate stormwater runoff from each of the three ( 3 ) sites into Halfmoon Lake . 5 . Develop final measurements to calculate pollutant reductions . Prepare Non - Point Source ( NPS ) pollution site reports and Pollutants Controlled Reports ( PCRs ) for the Site . 6 . Prepare conceptual stormwater BMP designs , estimated cost of materials , and implementation costs to mitigate stormwater runoff at several additional BMP sites as selected by HMLA . Calculate pollution load reductions on these sites after BMP implementation by HMLA , private contractors , and / or community volunteers .
