Project Description
• Tax Map 35I, Grid 19, Parcel, 1288
• Located in the Northwest portion of the Town of Centreville along Chesterfield Avenue
(Public Street) and the Yellow Bank Stream, a tidal headwater tributary of the Corsica
River.
• Subject property is a 46.869 acre site with existing vacant home, agricultural field and
wooded shoreline with steep slopes leading to non-tidal (1.263 AC) and tidal (6.396 AC).
wetlands. A short section of tributary stream exists in the southwest portion of the
property. 0.72 AC of tidal wetlands on County portion of the property are mapped as
“State Wetlands” per the 1972 State Wetland Maps. Wetlands and streams as shown on
the Environmental Features Plan have been reviewed by Chris Pajak, Maryland
Department of Environment. Nontidal wetlands as shown have been reviewed by the
U.S. Army Corp of Engineers and a Jurisdictional Determination Verification Map was
approved April 1, 2014 (Attachment #1).
• All steep slopes 15 percent or greater, tidal wetlands, non-tidal wetlands and streams are
protected by an Expanded Buffer of 12.505 AC. Tidal wetlands are not included in the
Expanded Buffer. The methodology and calculations used for Buffer Expansion for Steep
Slopes and Tributary Streams is outlined in detail on the Environmental Features Plan.
• The Critical Area calculations, methodology and Buffer Expansion as shown on the
Environmental Features Plan have been previously reviewed and approved by the
Maryland Critical Area Commission in association with a prior approval of Growth
Allocation on this site associated with a different project in 2015 (Attachment # 2)
• Site elevations in the open field portions of the site range from approximately 55 feet to
16 feet as shown on the Environmental Features Plan. Shoreline Buffer areas contain
steep slopes many exceeding 15 percent. An Expanded Buffer is proposed for areas of
steep slopes. All upland areas of the site drain towards the Yellow Bank Stream.
• As shown on the Environmental Features Plan the 100 year Flood Zone (AE elevation 6
ft) is located within the Expanded Buffer and does not impact the proposed development.
• 44.757 AC of Parcel 1288 located within Town limits has a Critical Area Limited
Development Area (LDA) designation.
• 2.112 AC is located in the unincorporated portion of Queen Anne’s County. The
unincorporated area of the property is almost exclusively tidal wetlands and is designated
as a Critical Area Resource Conservation Area. (RCA)
• Proposed PUD development includes 126 total non-riparian residential units consisting of
single-family detached homes, townhomes, multi-family, shared residential and
commercial parking areas, adaptive re-use of the existing farm residence, neighborhood
Page 2 of 7

commercial space, a community farm, community open spaces, public and private streets,
multi-modal pathways, perimeter trail and two overlooks and Environmental Site Design
stormwater management features. The project is proposed to be constructed in several
phases.
• Growth Allocation from LDA to IDA is requested for 40.372 acres. (entire site area
minus unincorporated area and area of tidal wetlands)
Recent Subdivision/Development History
• The property has not been developed or subdivided since December 1, 1985. The site
includes a private single-family, detached residence that pre-dates December 1, 1985.
The site is listed in the Maryland Historic Trust (MHT) Inventory. (QA-333) An inquiry
has been made to MHT concerning a records search for any significant archeological
resources which may be present on the site. No information has been provided to date
although it is believed the site once contained a historic home which burned down in
1908
• The site received Concept Plan approval for a proposed TND development and Critical
Area Growth Allocation approval for 40.372 acres IDA designation in 2015. This project
was not moved forward by the previous developer.
Project Narrative Overview
• The proposed PUD is designed as an environmentally-sensitive and agrarian-themed
neighborhood developed around a protected forested Critical Area Buffer, other
community open spaces and a working community farm. The proposed community is
pedestrian-friendly with a hierarchy of public streets, living streets (Woonerfs) and other
multi-modal pathways and sidewalks connecting all parts of the community. Shared
vehicular parking is proposed instead of traditional residential driveways in a majority of
the developed area. All residential homes have required access for delivery, service and
emergency response vehicles.
• A 12.505 AC± completely forested Critical Area Buffer with expansions for steep slopes
is proposed.
• Proposed development, excepting portions of a proposed public trail and two observation
overlook areas, is limited to the area of the site outside of the Expanded Buffer. (27.968
AC)
• Town of Centreville 2009 Community (Comprehensive) Plan identifies Centreville as a
“Growth Area” for Queen Anne’s County.
• The Plan’s Future Town Land Use Map, Figure 11, (Attachment #3) identifies the site as
appropriate for “Traditional Neighborhood Development.” Through numerous work
sessions with the Town Planning Commission and Town Council, it has been determined
that the proposed development is a form of Traditional Neighborhood Development
subject to pending PUD Zoning Ordinance and Subdivision Regulation text amendments.
• Maximum density permitted in the TND Zoning District with a PUD is 5 dwelling units
per acre. Proposed density is 2.8 dwelling units per acre (126 units/44.75 AC total site
area).
• Figure 12, Future Town Growth Area and Greenbelt (Attachment #4) identifies the site as
an “Infill Area” and shows a Proposed Greenway along Yellow Bank Stream. The
greenway is further described on Page 5-6 of the Centreville Community Plan.
Page 3 of 7

(Attachment #5) The Plan objective is to provide a greenway and path for The North
Brook subdivision east of MD RT 213 all the way to the Town Wharf property just west
of the project site and ultimately to the existing Mill Stream path and greenway on the
west and south sides of the Town. The proposed project provides the greenway buffer
and public path connections generally envisioned in the Town’s plan.
• The proposed project will be served by public water and sewer. Town Staff has indicated
that the Town’s wastewater treatment plant (WWTP) currently has capacity for the
proposed development. While only limited preliminary engineering for utilities has been
performed to-date, it is anticipated that a gravity collection system will be used on-site
with conveyance to the nearby Centreville WWTP via on-site pump stations with
shellfish protection measures and a force main crossing the intervening Board of
Education property. Public water would be a loop system into existing water mains
which would also include a crossing of the Board of Education property to the existing
water storage tower. The developer will be responsible for acquisition of sewer and
water allocation and for all on-site and off-site public water and sewer improvements
necessary to serve the project.
• The subject site is designated on the Town’s Critical Area Map as “Infill Growth
Allocation Area” (Attachment #6). This is consistent with the Town’s Comprehensive
Plan and Zoning Ordinance as outlined above.
• The proposed Growth Allocation from Limited Development Area (LDA) to Intensely
Developed Area (IDA) is entirely consistent with the Town’s Comprehensive Plan,
Zoning Ordinance and Critical Area Program. The site was previously approved for
Growth Allocation by the Town and Critical Area Commission in 2015 as a Refinement
to the Town’s Critical Area Program since the site was identified and pre-mapped for
Growth Allocation.
Critical Area and Growth Allocation Acreage
• The entire property is located within the Critical Area 46.869 AC.
• 44.757 acres are within Town limits and are designated as Limited Development Area
• 12.404 acres within the Town limits are in Expanded Buffer
• 4.385 acres are tidal wetlands within Town limits
• 2.112 acres are within the County and are designated as Resource Conservation Area
(RCA) and are not proposed for development disturbance or Growth Allocation.
• 2.011 acres within County are tidal wetlands of which 0.72 acres are “State Wetlands.”
0.101 acres are upland and part of the Expanded Buffer
• Growth Allocation from LDA to IDA is requested for the 40.372 acre Town portion of
the site including the Expanded Buffer within Town limits (12.404 AC) and not including
the 4.385 acres of tidal wetlands within Town limits.
• The Town of Centreville currently has 180 acres of Growth Allocation available.
Proposed Forest Clearing
• Total forest on the site is 11.664 acres and is predominantly located within the Expanded
Buffer. As shown on the PUD General Plan there are a few locations where existing
forest cover extends slightly beyond the Expanded Buffer but no clearing of existing
forest is proposed beyond minimal clearing necessary for construction of a Public Trail
within and slightly outside of the Expanded Buffer. Trail alignment and design are still
Page 4 of 7

conceptual at this point and will require coordination between the developer and the
Town to ensure the Trail is compliant with all applicable Town, State and Federal
requirements for public access.
Stormwater Management Concept
• A Concept Stormwater Management (SWM) Plan has been prepared by Common
Ground to address the County Stormwater Management Ordinance and Critical Area 10
Percent Rule requirements. The SWM features proposed to be utilized are shown on the
SWM Concept Plan and include Best Management Practices (BMPs) such as Micro
infiltration, non-roof top disconnection, bioswales, green roofs, permeable pavers, rain
gardens, and grass swales.
• Engineering and construction plans for SWM and a complete SWM report will be
reviewed and approved by the Town, County and Critical Area staff as a condition of
final development approval.
Ten (10) Percent Pollution Reduction
• By adhering to new State and County regulations and standards for SWM, it is not
anticipated that the project will have any difficulty adhering to the Critical Area 10
Percent Rule for IDA development which requires that pollutant loads from a
development site be reduced to a level at least 10 percent below the same load generated
by the site prior to development.
• Preliminary calculations prepared for the Concept SWM Plan indicate that phosphorous
loads will be reduced by more than 10 percent from pre-development levels and that
Environmental Site Design treatment volume requirements will be met.
• Engineering and construction plans for SWM and a complete SWM report will be
reviewed and approved by the Town, County and Critical Area staff as a condition of
final development approval.
Soil Erosion and Sediment Control
• A Limit of Disturbance (LOD) will be established for the area proposed for development
construction activity. This LOD will not encroach on the Expanded Buffer.
• A detailed Sediment and Erosion Control (SEC) Plan will be prepared and approved by
the Queen Anne’s County Soil Conservation District (SCD). This plan will detail
measures and a sequence of construction to be used to minimize sediment and erosion
while the site is under construction and before it is properly stabilized.
• Queen Anne’s County Department of Public Works will issue a grading permit and all
sediment and erosion control devices will be subject to posting of a surety.
• A pre-construction meeting is required with Town, County and State officials to confirm
sediment and erosion control methods to be used and the sequence of construction.
• During construction there are regular reporting and inspection requirements with the
Maryland Department of Environment.
Critical Area Lot/Site Coverage
• Lot/site coverage limitations will not apply to the IDA portion of the development.
• The lot coverage proposed within the Expanded Buffer (LDA) portion of the site is the
proposed public trail and overlooks. Lot coverage in the LDA portion of the site is
Page 5 of 7

limited to 15 percent. Conceptual design for the public trail within the Expanded Buffer
(LDA) is a 5 ft. wide crushed limestone dust trail of approximately 4,100 LF totaling
approximately 20,500 SF. The Expanded Buffer is 12.404 AC. Lot coverage for the trail
is 3.7 percent of the LDA area.
Mitigation for Forest Clearing
• Mitigation for limited clearing for the Public Trail and overlooks will be required based
on amount of clearing proposed for these paths within and outside of the Expanded
Buffer. It is anticipated that the specific trail alignment and construction will work
around existing trees to the maximum extent possible so clearing is limited.
• Mitigation planting amounts will be determined with the final design of the proposed trail
as designed.
Proposed Afforestation
• No afforestation is required for IDA development other than that which is required within
the Expanded Buffer as part of an approved Buffer Management Plan. The proposed
development will be required to comply with Town Landscaping and Tree Canopy
regulations.
Local Zoning
• The property is currently zoned as Traditional Neighborhood Design (TND). A TND
Planned Unit Development (PUD) is proposed.
• The proposed project is designed to be consistent with the adopted TND regulations as
modified by pending zoning text amendments for the PUD overlay or floating zone.
Maximum density permitted is 5 dwelling units per acre. Proposed density is 2.8
dwelling units per acre (126 units/44.75 AC total site area).
Buffer Management Plan
• The Buffer Management Plan for this project will require complete
afforestation/establishment of the expanded Buffer except for areas used for the Public
and Community Trails. There are a few small areas where the Expanded Buffer extends
into the existing farm field. These Buffer Areas will be required to be afforested using
native species plantings and per the quantities and plant mixes as prescribed by Critical
Area Buffer Management Plan regulations.
• The Conceptual Critical Area Buffer Management plan shows approximately 1.6 acres of
proposed afforestation within the Expanded Buffer. Proposed plantings for afforestation
of this area include native canopy trees, understory trees and large shrubs creating a
multi-tiered canopy.
• The final Buffer Management Plan planting amounts will be determined with the final
design of the proposed public path and overlooks as designed.
Habitat Protection Plan
• The Maryland Department of Natural Resources (DNR) Wildlife Heritage Service has
determined in a letter dated April 28, 2021, that there are no State or Federal records for
rare, threatened or endangered species within the boundaries of the project site as
delineated. Open waters that are adjacent to the site are known historic waterfowl
Page 6 of 7

concentration areas. DNR remote sensing analysis suggests that the forested areas on the
property provide habitat for Forest Interior Dwelling Birds (FIDs). (Attachment #7).
• No woodland clearing is proposed that would disturb any possible FIDs habitat and no
marine construction is proposed that would disturb migratory waterfowl.
• Virginia Institute of Marine Sciences (VIMS) 2019 mapping indicates no submerged
aquatic vegetation (SAV) in waters adjacent to this site.
• Figure 7, Natural Resources Map from the 2009 Centreville Community Plan identifies
the area of Yellow Bank Stream on the western edge of the site as anadromous fish
propagation waters.
• Based on the above information a Habitat Protection Plan should not be required with this
proposed Growth Allocation request. The developer should consult with the Maryland
Department of Natural Resources before proceeding with any marine permit and
construction activity related to any future proposed marine construction.

RE: Environmental Review for 408 Chesterfield Avenue, Centreville, Tax Map 351, Parcel 1288, Lane
Job #210117 File C923, Queen Anne’s County, Maryland.
Dear Ms. Usilton:
The Wildlife and Heritage Service has determined that there are no official State or Federal records for listed
plant or animal species within the delineated area shown on the map provided. However, our remote analysis
suggests that the forested area on this property provides habitat for Forest Interior Dwelling Birds. Many species
of forest interior breeding birds are declining in Maryland. This group of bird species requires large, contiguous
blocks of forest to successfully breed. Most FIDS are neotropical migrants; these long distance migratory birds
breed in North America and winter in Central and South America. The declines in FIDS have been attributed
largely to the loss and fragmentation of forests in the eastern United States due to urbanization, agriculture and
some forest management practices. Tropical deforestation on the wintering grounds also is an important factor.
The key to maintaining suitable breeding habitat for FIDS, and halting or reversing their declines, is the
protection of extensive, unbroken forested areas throughout the region. Riparian forests are particularly
important habitat for several FIDS that breed on the Coastal Plain. The conservation of this habitat is mandated
within the Chesapeake Bay Critical Area and must be addressed by the project plan. Specifically, if FIDS habitat
is present, the following guidelines should be incorporated into the project plan (as applicable): 1) Do not
remove or disturb forest habitat during April-August, the breeding season for most FIDS - This seasonal
restriction may be expanded to February-August if certain early nesting FIDS (e.g., Barred Owl) are present; 2)
Avoid creating canopy openings, and maintain the complexity of forest structure along the stream, and 3) Retain
snags and retain woody debris on the forest floor.
The Critical Area Commission’s document “A Guide to the Conservation of Forest Interior Dwelling Birds in
the Chesapeake Bay Critical Area” provides details on development standards and information about mitigation
for projects where impacts to FIDS habitat cannot be totally avoided. Mitigation plantings for impacts to FIDS
habitat may be required under the local government’s Critical Area Program. The amount of mitigation required
is generally based in whether the guidelines listed above are followed.
Also, we would like to point out that the open waters that are adjacent to or part of the site are known historic
waterfowl concentration areas. If there is to be any construction of water-dependent facilities please contact Josh
Homyack of the Wildlife and Heritage Service at (410) 827-8612 x100 or josh.homyack@maryland.gov for
further technical assistance regarding waterfowl.
