Site Analysis - General Site/Civil/Fields

View Across Playfields View at Smith Lot Exit

Site Issues

• Storm drainage appears insufficient; ponding observed along paved edges

• Downspouts discharge directly onto ground

• Parking lot to east of Reed half underwater occasionally

• Driveways, parking lots, sidewalks and curbs in fair to poor condition

• Handicap accessibility does not meet MAAB code

• Water table is high, causing seasonal wet conditions at fields



Permitting Issues - Wetlands

• Wetlands Protection Act (310 CMR 10.00) – The site falls within an environmentally sensitive area and a Notice of Intent is required, the wetland resource areas include:

• Riverfront – Critical to have the limit of Riverfront determined, this has a direct impact on project

• Bordering Vegetated Wetlands• Bank• Land Underwater

• Lincoln Wetlands Protection Bylaw - includes 50-foot “no disturb area”

• Natural Heritage & Endangered Species – the site does not fall within Priority or Estimated Habitat and does not contain a certified vernal pool per MASSGIS

• Flood Plain – the majority of the site is not located within a 100-year floodplain. There is a 100-year floodplain associated with Stony Brook but is generally confined to Stony Brook channel.

Limit of Riverfront Area?

Wetland Map From Lincoln GIS



Permitting Issues

• Zoning - Zone – R-1, Single Family Residential – the zoning for schools vary greatly depending on the Town’s regulations and their interpretation of the Dover Amendment. The Dover Amendment exempts schools from certain requirements of a Zoning Bylaws and Ordinances. It is critical to have a full understanding of the Towns interpretation of the Dover Amendment and the requirements and extent of review.

• Surface Water Supply Protection – site falls within water supply protection zone – Zone II, this will impact the drainage design.

• USEPA NPDES – disturbances over one acre require a submission of a Notice of Intent (NOI) that includes the stormwater pollution prevention plan to the EPA prior to beginning construction. This permit is signed by the operators of the construction site – the Owner and the Contractor

• Sanitary Sewer – There is a functioning existing 14,000 gallon per day Title 5 Septic System (1994) on site. Recommend the existing site be maintained. The function, size, and status of the existing Septic System will need to be confirmed with the Board of Health.



Existing Septic Information

3 septic fields • Main leach field under the soccer field (13,792 gpd) – 1994 designed for

14,000 gpd –not a pressure dosing system - works on a siphon • Hartwell School leach field (2,880 gpd) – 1969 no design flows available• Codman Pool leach field (2,500 gpd) – 1984 no design flows available• Total of 19,172 gallons per day based on Title 5

• Board of Health could require installation a wastewater treatment plant to come into compliance with Title 5 and Groundwater Discharge permit

• It appears that the septic leach fields were functioning in 2000 and that the

nitrogen loading was below the 10 mg/l required

• The 2000 GZA report also indicated that the actually flows based on water meter readings was approximately 2,800 gpd (15% of design/Title 5) in 2000

• The GZA report indicated that monitoring wells were installed to monitor the water table water quality.

• In general, Massachusetts General Law M.G.L. c.148, s.26G requires that any existing building, including any additions or major alterations, which total more than 7,500 square feet in aggregate floor area must be sprinklered. Should the existing building undergo a major renovation the building will require an automatic sprinkler system to provide complete protection of all spaces.

Lincoln Public Schools Mission

“The Lincoln Public Schools seeks to unite our communities in challenging and equipping our students to:

• Acquire essential knowledge

• Think critically and independently

• Exhibit academic excellence

• Appreciate and respect diversity

• Demonstrate creativity

• Value reflection

• Work hard and play fair.”



Educational Philosophy Summary

• Two Schools within a School: The philosophy and curriculum are articulated and aligned as a K-8 program, however, operationally the scheduling, structure and administration are separate between the elementary and middle schools.

• Relational teaching bound by a community of learners: Communities are formed by the classroom, the grade, the school and the families.

• Enrollment Projection: 600 students confirmed.

• Preferred Class Size: 18 (K); 20 (1st); 21 (2nd-3rd); 22 (4th- 5th); 24 (6th-8th).

• Grade transition is seamless within and between buildings.

• Scheduling of Space: One teacher per classroom. Classrooms are clustered by grades. Specialized spaces support grade group clusters.

• A high level of intervention, support and collaboration within classrooms reduces special education needs.

• Physical structure should promote collaboration.

• Transition from “curriculum silos” to “project based learning” opportunities.

• The school is a green community interlaced with the greater community.



A Shared View

“For a Pre-K-8 education, [the students] are together in the circle…

This is community.”



Next Steps
