1. The sidewalk in front of my house is broken or uneven, and I'm afraid someone may trip over it. Who's responsible for fixing it?: If the sidewalk is broken or has settled unevenly due to age, then you as the property owner are responsible as described in the City Code Section 22-60.

2. Why does the sump pump in my basement run all the time when it rains?: When this happens it is usually because the water being discharged from your downspouts has no place to drain or the ground around your house may need to be graded so water runs away from the walls towards the street. You may contact the Sewer Department at 301-759-6426 for additional assistance.

Where can I find this information?: The Community Development Department (301-759-6442) has Flood Maps from the Federal Emergency Management Agency National Flood Insurance Program (NFIP). They will compare your street address to the NFIP maps and can issue you a statement declaring your flood zone.

I am looking to develop a site and need to know what utilities are available?: The Engineering Department maintains the city's water and sewer utility maps, and in most cases can provide you with this utility information.
