About this file
This is a Solicitation Amendment (Amendment 1) issued by the State of Maine Department of Agriculture, Conservation and Forestry, Maine Geological Survey for RFP#202603043 regarding the Resilient Maine Coastal Bluff Mapping Update project. The amendment, revised as of October 16, 2025, modifies the study area figure to clarify the extent of bluff mapping activities, distinguishing between currently mapped bluffs with classified stability (green), unmapped areas (red), and areas mapped as non-bluffs (black). The amendment adds an exclusionary area on the southwestern corner of Mount Desert Island that is to be excluded from all field mapping and ground-truthing efforts. Under the Scope of Services, a new section detailing Existing Datasets has been added, specifying datasets available to bidders including VEXCEL, NEARMAP, and GoogleEarth imagery; MGS Oblique Coastal Air Photos from 2025; NOAA 2022-2023 Topo-bathymetric LIDAR data; coastal bluff features and related layers; and various habitat and environmental sensitivity datasets from NOAA, SIFW, DMR, and MDEP. The contract term under Renewal Period 1 has been revised with an end date of August 31, 2029.
The amendment provides comprehensive geospatial and environmental datasets to support the coastal bluff mapping update, including topographic, bathymetric, imagery, and ecological information from multiple state and federal sources. These datasets are made available to facilitate accurate mapping and ground-truthing of Maine's coastal bluff features and their stability classifications. The extended contract end date to August 31, 2029 reflects the project's multi-year implementation timeline for completing the resilient coastal bluff mapping initiative across the specified study area.
