Community Meeting , November 26, 2012
Banner, Buchanan, Crittenden 40th Ave Project
Budget Presentation
Project Scope (General) The Banner, Buchanan, Crittenden, 40th Avenue project scope is to address a number of deficiencies having to do with sidewalks, street trees, roadways and stormwater drainage.
1. Besides general sidewalk issues having to do with maintenance related to heaving of tree roots and settlement creating tripping hazards along with stormwater damming in residential yards, the current sidewalk route is not ADA compliant and needs to be extended.
2. A solution needs to be developed to address significant tree root girdling due to lack of space between the sidewalk and curb on Banner Street where one condition is threatening a PEPCO power pole. Also a separate issue is the threat to the power and communication infrastructure by tree growth (limbs) encompassing the PEPCO and Verizon lines on Banner and 40th Avenue. Pruning to create clearance may not be adequate.
Budget Presentation
Project Scope (General cont) 3. A tree management plan for the existing trees will need to be
established along with a new tree planting plan. New design features for tree boxes (curb bump outs?) will need to be developed and incorporated into the overall project plan.
4. A comprehensive stormwater drainage plan of the Banner, Buchanan, Crittenden, 40th Avenue project needs to be developed to create positive drainage to all of the stormwater structures to stop ponding in the roadway and creating erosion at each.
Additional stormwater structures (rain gardens, etc) need to be developed at both ends of Buchanan Street and at the Crittenden Street cul-de-sac terminus.
Existing roadway and curb elevations will need to be surveyed and reengineered , requiring removal and reconstruction.
Budget Presentation
Project Design Principles 1. The project design will make every attempt to preserve the
character of the neighborhood.
2. Provide safe accessible pedestrian access throughout the neighborhood in conformance with the City Sidewalk policy.
3. Comply with the City’s Sustainability policy and best practices.
4. Reduce vehicular traffic and vehicle speeds.
5. Avoid right-of-way impacts to residents and limit impacts to owner improvements within the right-of-way
6. Save existing mature trees, and where necessary recommend native species for new planting.

Project Schedule
Budget Presentation
Project Scope (Preliminary BAI Proposal) Proposed deletions in red and additions underlined
BAI understands that the City of Hyattsville desires to upgrade Banner Street, Buchanan Street, Crittenden Street, 40th Avenue, and Alleys 8 and 9 in the city of Hyattsville, MD. The improvements will encompass the entire “block” in this area, and will be designed to tie in accordingly to the Crittenden Street 40th Place Improvements project.
These improvements will be based on the City-provided list of issues submitted to BAI on August 15, 2011, containing details on specific engineering upgrades needed in the project area and in accordance with the City’s Sidewalk policy and Environmental Sustainability Policy.
Budget Presentation
(Preliminary BAI Proposal continued) Additionally, the following design principles will be incorporated into the project: safe pedestrian facilities, sustainability, reduced vehicle speeds, avoidance of right-of-way impacts to residents, avoidance of impacts to surface/subsurface utilities, reduced vehicular traffic, and limiting impacts to owner improvements within the right-of-way. The design will make every attempt to preserve the character of the neighborhood, save existing mature trees, and recommend native species for new planting. Upgrades to these streets will include: 1. Partial or Full-depth patch, as necessary, any areas exhibiting
pavement distress. 2. Mill and overlay the surface course on all the roadways. 3. Wedge and level pavement to establish positive drainage
throughout.
Budget Presentation
(Preliminary BAI Proposal continued) 4. Reconstruct curb and gutter, in-kind, as necessary. 5. Reconstruct all ADA non-compliant sidewalks in the project area. 6. Resolve concerns over varying cross-slopes of existing sidewalk. 7. Redesign sidewalk to alleviate drainage issues on all streets
Banner Street and Crittenden Street, remove tripping hazards and comply with the City’s sidewalk policy.
8. Resolve drainage issues on the following streets/locations: •Intersection of Crittenden Street and Alley 8 •Crittenden Street terminus at trail head •Banner Street, Buchanan Street, Buchanan Street terminus •40th Avenue terminus •Intersection of Buchanan Street and Alley 9 •And up to six additional locations that the City identifies
Budget Presentation
(Preliminary BAI Proposal continued) 9. Re-engineer the Crittenden Street terminus, the Buchanan Street
terminus and determine the feasibility of installing rain gardens or other storm water management facilities.
10. Re-engineer the 40th Avenue terminus to address drainage issues, prevent soil erosion and determine the feasibility of installing a rain garden.
11. Address conflicts while minimizing impacts to existing trees. Potentially narrowing roadway to create new sidewalk paths and tree boxes of adequate size.
12. Obtain all permits for performing the work. “Blanket” permits from PG DER and PG SCD may be warranted, depending on disturbed area calculations.
Budget Presentation
(Preliminary BAI Proposal continued) 13. Take inventory of all existing pavement markings and signage and
ensure that they are adequate and meet standards, and are replaced correctly following any improvements.
14. Clean, rehabilitate or replace any roadside drainage appurtenances, as needed, including grate replacement.
Additionally, upgrades will include: 15. Storm drain inlet installation and system connection at SB 40th
Avenue and Buchanan Street 16. System connection of existing storm drain inlet at NB 40th Avenue
and Buchanan Street 17. Stabilization of the area south west of the intersection of 40th
Avenue and Buchanan Street
Budget Presentation
(Preliminary BAI Proposal continued) 18. Coordination with PEPCO utility work including pole relocation
Budget Presentation
Next Steps (next 60 days) 1. Receive comments from residents
2. Review overhead tree issues with PEPCO and Verizon
3. Revise Scope and negotiate BAI engineering proposal
4. Report out to City Council and residents. Seek approval of revised BAI engineering proposal.
5. Start engineering work for project.
